"I've only heard that name once. From Kanan. He said Mustafar is where Jedi go to die."
―Hera Syndulla — (audio) Listen (file info)[src]

Mustafar was a small planet located in the Mustafar system, within the Atravis sector of the galaxy's Outer Rim Territories. Once a garden world nourished by the Bright Star artifact, its orbit was shifted when Lady Corvax unleashed the energies of the Bright Star in an attempt to return her husband to life. The resulting gravimetric duel between the gas giants Jestefad and Lefrani over Mustafar heated the planet's core, transforming the lush world into an imbalanced volcanic hellscape. Adapting to life on their devastated homeworld, the arthropodal Mustafarians evolved into two distinct subspecies that cooperated to ensure their continued survival. Legends of Corvax's search for immortality brought the ancient Sith to Mustafar, seeking the same secrets of eternal life. There, they built a temple over a locus in the dark side of the Force, above the buried ruins of Corvax Fortress.

Acquired by the Techno Union over three hundred years before the Clone Wars, Mustafar's lava flows were mined for unique and valuable minerals. It was also home to the Black Sun crime syndicate, whose headquarters was located near the mining town that became known as Zitontown after the Falleen Ziton Moj ascended to leadership of the organization. During the Clone Wars, the Mustafarians aligned themselves with the Confederacy of Independent Systems, who used Mustafar to produce battle droids for their droid army. Darth Sidious had a secret facility on the planet where he intended to turn "harvested" Force-sensitive children into Force-talented spies. However, the Sith Lord had the base scuttled when Jedi Knight Anakin Skywalker and his Padawan, Ahsoka Tano, arrived to rescue the younglings.

Mustafar served as the final redoubt of the Separatist Council until the newly-appointed Darth Vader, formerly Anakin Skywalker, was sent by Sidious to slaughter the council, effectively ending the Clone Wars. The Sith Lord was confronted by his wife, Padmé Amidala, and his former Jedi Master, Obi-Wan Kenobi. The latter dueled Vader, defeating him and leaving him to burn on a lava bank. However, Vader was saved when Sidious arrived and carried him offworld. Mustafar then came under the ownership of the Galactic Empire after the Techno Union and its assets were nationalized. Sidious had new facilities built on the planet, where more Force-sensitive infants were taken and transformed into agents of the Inquisitorius.

During this era, Vader returned to the site of his greatest defeat and, with the help of the ancient Sith Lord Darth Momin, erected the massive monolith Fortress Vader to serve as his personal sanctum, built on the site of the former Sith temple. Throughout the Age of the Empire, Vader used the planet to fulfill his master's biddings, with the fiery world becoming the final resting place for victims of the Great Jedi Purge. In addition, Vader also undertook personal business within his new realm, attempting to wield the dark powers of Mustafar to bring his deceased wife back from the dead. Following behind the Dark Lord of the Sith, the Empire took hold of planet. Resource extraction efforts on Mustafar were taken over by the Mining Guild, though strict Imperial travel restrictions on the system made it difficult for the guild to turn a profit and mining operations eventually ceased entirely. Black Sun also abandoned Mustafar for a more low profile world when the Empire established a garrison there. The Mustafarians resisted the Imperial occupation of their homeworld and attempted to drive them from Mustafar by launching multiple assaults on Fortress Vader.

Though it hosted one of the earliest rebel victories of the Galactic Civil War, Mustafar fell into obscurity following Vader's demise at the Battle of Endor. After the destruction of the Bright Star, the planet's ecosystem slowly began to heal from the devastation it had endured for centuries prior. Many devout pilgrims journeyed to the ruins of Fortress Vader, hoping to tap into the late Sith's dark power. Decades after Vader's death, his grandson, Kylo Ren, journeyed to the world to continue the legacy of his family's grisly past. The Supreme Leader of the First Order slaughtered the Sith cult that defended Fortress Vader and discovered his grandfather's Sith wayfinder, a tool that allowed him to locate the phantom emperor Sidious on Exegol.

Description[]

World of fire[]

"Mustafar is a lava planet, terrible place, full of awful mines. There's a custom there to jump lava flows and…well, you'll see."
―L3-37[src]

The landscape of Mustafar during the day

A small planet located in the Atravis sector of the Outer Rim Territories[31] within the eponymous system,[4] Mustafar was situated on the Tosste Spur trade route, off the Rimma Trade Route,[5] in grid square L-19[8] of the Standard Galactic Grid.[32] Located 53,000 light-years from the galaxy's Core,[5] Mustafar was once a lush world thriving with life, thanks to the power of the Bright Star, which nourished what came to be known as a garden world.[12]

Millennia before the Imperial Era, however, Mustafar become an unstable volcanic world, with lava constituting 35% of its surface. Occupying the third orbit of its system around the primary star Priate, the tortured planet[5] was powerful in the dark side of the Force,[33] and, along with its valuable mineral allotropes that surfaced from the planet core[31] as well as its obscurity to the wider galaxy, attracted various off-world interests that exploited the molten planet.[10] Mustafar remained a fiery world until the destruction of the Bright Star, at which point the planet was allowed to regrow.[34] Such different states of the world led some to believe that spiritual forces were the catalysts to the changes in Mustafar's nature.[7]

Heart of lava[]

Deep underground, Mustafar contained lava lakes from which fumes drifted up to surface-level facilities; such fumes played tricks with the minds of organics who inhaled it, giving rise to what Lellis referred to as "shadows of the mind"—visions of fears and doubts that could manifest as ghosts of the past. Such gases were most potent around the vicinity of the Mustafarian Mining Complex, and sustained exposure to it drove an individual insane. Repulsor vents were thus installed at the Mining Complex to prevent such toxic fumes from rising to indoor facilities and being inhaled by those within.[27]

Orbiting close to the gas giant Jestefad, with which it was twinned, Mustafar was constantly pulled by the gravitational force of the nearby planet, which nearly captured the smaller world as its moon; only the counterbalancing gravitational pull from the more remote gas giant of Lefrani prevented it from being claimed as Jestefad's orbit. In spite of such, Mustafar possessed a standard gravity. The influence of the massive magnetic field of Mustafar's larger twin, however, resulted in its hellish volcanic landscape, as the power of Jestefad's gravitational force caused massive tidal disruption that heated Mustafar's interior.[11] Along with being engulfed in a constant gravimetric battle, Mustafar housed an unstable core that caused groundquakes powerful enough to split the planet's continents apart,[35] and its split tectonic plates allowed the planet's searing magma to push through to the surface, creating a volcanic hot spot visible as a bright red cluster from space.[7]

While great portions of the planet were always in motion, one of the few constant features was the central volcano. Lava poured out of the spot at nearly 100,000 litres per second and pooled at the giant volcano's base. To the north was a region named the Burning Plains, which boasted heavy volcanic activity. Another region earned its nickname, the Smoking Forest, as smoke spewed from its tree-like rock chimneys. Mustafar's Berken's Flow was the largest lavafall in the galaxy, while a landmass named Tulrus Island was surrounded by tall mountains.[5]

The young[5] world's instability churned magma carrying ores[7] with unique and valuable minerals[36] to its surface,[7] attracting business interests[11] from various[2] galactic mining conglomerates[7] such as the Mining Guild[2] to exploit the mineral wealth of the otherwise untouched world.[11] The searing magma that bubbled beneath the surface flooded the planet, covering it in oceans[13] and rivers of lava. Geothermal energy was the main power source of the Techno Union's mining complex on the planet,[11] and the lava flows that coated the rocky terrain left behind traces of flood basalt.[37] At 800°C (1500°F), Mustafar's lava, while still very hot, had a lower temperature than that found on other worlds due to unusual mineral allotropes that were molten at lower temperatures.[11] Nevertheless, patches of Mustafar began to cool in the decades leading up to[7] 35 ABY.[38]

Tempestuous skies[]

Mustafar featured rivers of lava.

Mustafar's atmosphere was influenced by the breath of its volcanoes and Jestefad's massive magnetic field. Along with cyclonic-force updrafts and thermal currents, titanic lightning storms made up the planet's unfriendly skies. Turbulent and ash-laden,[11] the atmosphere was also hot and chemical,[39] consisting of thick clouds of black smoke[19] and allowing for[35] choking ash[29] to fall like rain.[35] Lava processing operations created toxic gas by-products,[11] and a noxious air cast the world in a hazy fog.[39] Thus, Mustafar was classified as a world with a Type II atmosphere, wherein the usage of a breath mask was recommended.[5]

The frequent[31] electromagnetic interference and lightning storms in the atmosphere led to signal loss and noise respectively, though the effects of Mustafar's hectic skies could be reduced through the use of dedicated dampers. However, electromagnetic interference also posed a significant risk for off-world arrivals and departures.[11] Those caught in one such storm[37] without the assistance of specially shielded surface-level landing equipment[11]—which included energy-shielded[31] landing pads and guidance and tractor beams—found, at best, their starship's scanners rendered useless and navigational equipment and control systems interfered with.[11] In certain cases, a ship was torn apart[37] as Mustafar was by Lefrani and Jestefad.[11] Ships were additionally threatened by Mustafar's intense heat and incendiary ash, though any damage could be prevented should a vessel be equipped with sufficiently powerful energy shields.[40]

Fauna and flora[]

Hardy beasts[]

"The very beasts themselves conspire to thwart my vision. Fascinating. Utterly fascinating."
―Lord Momin, reacting to a lava flea attack on Fortress Vader[src]

Northern Mustafarians ride lava fleas along a molten river.

Despite its hellish environment, Mustafar was teeming with life, a home to fragile but determined organisms all connected through the Force.[39] In the solid rock betwixt lava flows, there lived mammalian, reptillian, as well as insect species.[5] The extremophile creatures of the planet had adapted to Mustafar's desolation and become indomitable.[39]

The large insectoids known as lava fleas had developed a tough exoskeleton that protected them from the fiery devastation of the world. They were known to eat away at the planet's crust and were commonly used as mounts by the sentient Mustafarians, who were insectoids themselves.[29] Other species found on the planet included lizard-crows, which could be found in Mustafar's lava fields; these creatures were often scared away by what the Mustafarians referred to as "molten men."[24] Spark-roaches[27] and rodents called fire rats also called Mustafar their home, the latter of which were known to gnaw on the lava crystals that formed on the planet.[21]

Similar to lava fleas, xandanks were another insectoid species well protected by their armor; those beings were predators native to Mustafar that hunted in packs.[41] Tough, semi-sentient creatures[42] known as roggwarts hunted the planet's tunnels and lava tubes in search of xandanks,[43] as well as for giant, man-eating[23] lava eels. Despite the danger of roggwarts, they could be domesticated with the proper training[43] and were imported to Mustafar to work in the planet's mines.[26]

By 3 BBY, a roggwart known as Kongo the Disembowler was employed to keep the dolovite mine tunnels free[41] of xandanks and lava eels.[23] Kongo was reputedly the last of his kind[42] by between 0 and 1 ABY,[44] although it may have been said in an effort to make the roggwart seem more mysterious and exotic.[42]

Life-forms lethal and unswerving[]

Much like the planet itself, some of the creatures found on Mustafar were especially deadly.[20] Highly aggressive creatures posed a significant hazard on the planet due to its scarce resources.[22] The fearsome darkghast, similar in some respects[20] to the rancors of Dathomir,[45] was a multi-limbed carnivore that could be found beneath the world's rocky surface. Lava nymphs, winged creatures that lived in hives, could also be found in the planet's caverns. Considered to be vermin, the creatures' insides were filled with lava, which they were able to spit out when provoked.[20] A species of beetle also inhabited the planet; starting life as a small larva, the creature developed a defense mechanism by the time it reached adulthood that allowed it to warn its brood by exploding.[25] Burrowing quadrupeds known as krishels inhabited Mustafar's labyrinthine caverns and tunnels. Those strong, hardshelled creatures were hunted by the Mustafarians.[22]

Irontrees were some of the few plants found on the world.

Although the lush vegetation that once covered the planet eventually disappeared beneath fire and ash,[12] Mustafar was not devoid of fungal and vegetal life. Hidden away from the world's searing lava rivers, kahel cave fungi grew underground. These organisms were deeply symbolic to the native Mustafarians and served as the inspiration for their mushroom-like architecture.[11] Following the destruction of the Bright Star during the Imperial Era, life began to slowly creep back once again.[34] By 35 ABY,[38] barren irontrees could be found within the few places where fertile soil existed,[7] such as the muggy marshland[35] of Corvax Fen.[7]

History[]

Cataclysm immortalized[]

"Once, our world Mustafar was green, filled with life."
―The Priestess teaches Mustafar's past to the descendant of Lady Corvax[src]

In its ancient past,[7] Mustafar was a lush and forested[12] terrestrial planet,[5] thriving with life through the Bright Star, the native Mustafarians' most sacred artifact that nourished[12] the small[11] garden world.[7] Ancient legends said that offworlders led by Lady Corvax and her husband arrived at some point, living in harmony with the natives. However, the garden world came under attack, and Corvax's husband fell in battle. Unable to let go of her love, Corvax stole the Mustafarians' Bright Star in her pursuit of immortality, having thought it had the power to resurrect her husband from death.[12]

Corvax created the Aeon Engine and encased the artifact within, although her actions ultimately resulted in the devastation of the planet;[12] energies ruptured from the Bright Star, pushing Mustafar out of its original orbit.[7] Legends claimed that due to a cataclysmic struggle between the Sith and the Jedi millennia before the Imperial Era, the orbit of[5] the gas giant Lefrani was also shifted, and Mustafar entered an unusual and gravitationally crushing alignment between[22] it and Jestefad's magnetic fields.[5]

Mustafar's new, precarious orbit rendered it a volcanic wasteland[12] as both gas giants pulled on tiny Mustafar, heating its interior in their attempts to claim Mustafar as their moon.[11] The crust of the smaller world was also torn apart, allowing the flow of lava toward the planet surface.[5] Very few species survived the cataclysm,[22] with the homes of nearly all native species being destroyed. The remaining life-forms evolved short, tough bodies to endure the superheated clime,[5] and the Mustafarians were forced to areas in Mustafar's north and near the equator. There, they adapted and evolved to the new realities of life on Mustafar.[22] These events passed into legend, attracting Sith who were looking for the secrets of eternal life. Eventually,[7] a Sith temple[11] and a Sith shrine was built on the world.[7]

A colony for mines and an outlaws' cove[]

Mustafar's surface transformed into a hellish landscape.

Over three hundred years before the Clone Wars, the Techno Union came to own the planet[31] and charged the Mustafarians rent.[7] The Union provided the Mustafarians with tools to mine mineral allotropes for them,[31] labor which served to pay their rent.[7] Mixed with workers of a great variety of other species, Mustafarian miners lived in simple residences at dedicated though run-down mining towns,[19][11] and were helped by Techno Union technology such as the Baktoid UH-XH repulsorlift-powered platforms,[22] lava-processing centrifuges,[11] electrorefining droids,[9] and the DLC-13 mining droid[29] to collect mineral-rich lava spewing from Mustafar's heated interior.[11]

Over the centuries, however, Mustafarians became wary of technology that[31] failed under the intense heat of their world and which had an inadequate melting point due to witnessing mechanical breakdowns. Such was the case for speeders, including the heavy-duty UH-XH, which were generally left to be operated by droids.[22] Nevertheless, by the end of the Clone Wars, Mustafar had served as a literal gold mine for the Techno Union for almost three hundred standard-years.[11]

Although Mustafar came to be known primarily for its mining activities, those desperate offworlders and law-evaders who were undeterred by the world's harsh conditions were drawn to it as a result of the obscure world's sparse population.[10] Mustafar was also ideal for hiding or disposing items in secret.[5]

Revenge of the Sith[]

Scum and villainy[]

Schemes and cabals[]
"I sense something, Master. And I don't like it."
"It's the dark side, Ahsoka. This is the right place."
―Ahsoka Tano and Anakin Skywalker — (audio) Listen (file info)[src]

During the Clone Wars, the Mustafarians aligned themselves with the Confederacy of Independent Systems. However, they were not fanatically committed to the cause, having only joined to secure themselves Separatist contracts, and life continued much as it had before.[22] With members of the Jedi Order, the galaxy's guardians of peace and justice, focused on defeating the Separatists, law enforcement found itself in a declining state, especially in the infrequently patrolled Outer Rim. Thus, organizations of the criminal underworld flourished, including Black Sun, a syndicate led by a cabal of Falleen nobles with interplanetary influence. The Falleen operated from the shadows,[46] establishing elusive holdings on Mustafar[22] and headquartering themselves in a well-defended fortress on the world,[46] where they regularly met[22] and found the surrounding lava useful for the disposal of evidence.[19] The native Mustafarians cared little for Black Sun, since most of their operations took place elsewhere in the galaxy.[22] Hidden away from prying eyes, the Techno Union also produced battle droids behind their mining operations on the planet at the time of the Clone Wars.[11]

Sidious secretly controlled a facility on Mustafar to train the kidnapped Force-sensitive children.

Aside from skirmishes and lesser operations, fighting largely passed Mustafar by during the Clone Wars.[22] In one instance, the planet bore witness to a plot to kidnap Force-sensitive children by bounty hunter Cad Bane, who deposited the children at a facility there for the Sith Lord Darth Sidious' plan to create an army of Force spies. However, Jedi Anakin Skywalker and Ahsoka Tano rescued the children, and the facility was destroyed by Sidious' nanny droids on the Sith's orders, ensuring the loss of any evidence of the plot's mastermind.[15]

In 19 BBY,[41] renegade Sith Lord Maul, his apprentice Savage Opress, and Pre Vizsla, the leader of the Mandalorian terrorist organization Death Watch, traveled to the Black Sun fortress with the intention of recruiting them into their criminal empire, the Shadow Collective.[14] The Captain of the Guard,[3] Ziton Moj, greeted them upon their arrival and led them to the Black Sun's leaders, headed by[14] the Falleen Xomit Grunseit, who hailed from Mustafar.[47] After negotiations with the leaders went sour, Savage beheaded all of them with his lightsaber. Moj became the new leader of the Black Sun, and joined with Death Watch, providing them with weapons, troops, and supplies.[14]

The lost children[]

The Black Sun was headquartered on Mustafar during the Clone Wars.

When Quinlan Vos was sent undercover as a bounty hunter to work alongside Dooku's former apprentice, Asajj Ventress, the pair was hired by the Pyke Syndicate to retrieve Marg Krim's wife, Tezzka Krim, and their children, Vram and Laalee, who were kidnapped by Black Sun and brought to their base on Mustafar in order to bribe the Pykes into joining Maul's Shadow Collective. The two traveled to Mustafar in the Ventress' ship Banshee and entered Zitontown seeking to gather information at the The Last Resort, the lone bar in the town. There, the pair interrogated a Falleen Black Sun enforcer and discovered where the prisoners were held. They infiltrated the lava-surrounded Black Sun fortress and rescued the children, though they later discovered that their mother was held in Ziton's palace. After the pair freed Tezzka, Moj had assembled his forces, which left Mustafar to attack the Pykes on Oba Diah.[19]

Mirror of the soul[]

The obviated war[]
"After you have killed all the Jedi in the Temple, go to the Mustafar system. Wipe out Viceroy Gunray and the other Separatist leaders. Once more the Sith will rule the galaxy, and we shall have peace…"
―Darth Sidious to his new apprentice, Darth Vader — (audio) Listen (file info)[src]

The Techno Union's Mustafarian Mining Complex served as the Separatist Council's refuge at the war's end.

As the war's end drew nearer, Anakin Skywalker made a pact with the Sith Lord Darth Sidious for himself to gain the power to save his lover, Padmé Amidala, from leaving him by death at the cost of submitting his soul as Darth Vader, Sidious' new apprentice. The fallen Skywalker was then sent by his new master to dispatch of the Separatist leaders previously sequestered by Sidious to the Mustafarian Mining Complex on Mustafar, traveling with a green Eta-2 Actis-class light interceptor and his droid R2-D2. Darth Sidious hoped for Vader to be bathed in the dark side of the Force and emerge stronger than even him, ordering his apprentice to transmit the order to Separatist assets subsequent to wiping out the Separatist leaders for the Separatist Droid Army to be deactivated immediately, effectively ending the war and allowing his Sith Master's newly-established Galactic Empire to seize control of the galaxy.[4]

A rumor spread over the fire plains of Mustafar that a Jedi Knight—a reputed protector of light, guardian of peace and life, and a hero of the Republic—had been spotted at the Mining Complex. The Mustafarian boy Kakan hoped to exact his dream of meeting a Jedi, and so approached the fallen Skywalker,[27] who was viewing[4] the eclipse of Mustafar's sun by Lefrani at the complex's balcony, just as Skywalker's massacre of the Separatists eclipsed the light of the Force within him.[11]

However, Kakan saw that the figure was not the Jedi he expected. The fallen Jedi's eyes radiated such anger and hate that Kakan was compelled to run away, escaping to the complex's foundry. Kakan found the miner Lellis, who operated the facility's repulsor vents, releasing fumes from the depths of Mustafar that gave one illusions when inhaled. The potent fumes overwhelmed the fallen Skywalker with his fears, and Kakan and Lellis took advantage of the former Jedi's distraction to escape. However, as fear took hold of the boy, the two Mustafarians fell into a lava lake, though they were saved by a burst of Force power released by the fallen Skywalker in a bout of anger.[27]

To not let go[]

Shortly after the slaughter of the Separatist leaders at[10] the Techno Union mining complex's secret war room,[11] Padmé Amidala arrived at Mustafar, having rushed to the volcanic world in the hope of saving her husband from falling further to the dark side.[10] Her pleas fell on deaf ears, however, when Vader spotted Obi-Wan Kenobi emerging from the ship. In his anger and his inability to let go of Amidala, Vader incorrectly assumed that his wife had betrayed him to Kenobi. Thus, he strangled his pregnant wife through the Force, demonstrating to her that Skywalker was consumed by his lust for power and became Darth Vader.[4][11]

Darth Sidious rescues his apprentice after he was left for dead by Kenobi.

Darth Vader then delivered an ultimatum that one was either with him or against him. Upon such a Sith trait of acting in absolutes, Vader was plagued by self-doubt and gave himself to the dark side, attacking his former friend and master; as he attempted to murder Kenobi, Vader bathed the remnants of Anakin Skywalker in the dark side of the Force that echoed from the Sith sanctum on Mustafar. Sabers clashed, and amidst the chaos, the shields protecting the mining facility were shut down, destroying parts of the building as well as the Lapiz Cutter, Separatist Council member Nute Gunray's personal shuttle.[48]

Forced to fight across the lava streams, Vader was fueled by hatred and, in his hubris, the fallen Jedi went without regard to his own limitations, and fell to Kenobi's blade. As the Chosen One lost himself to the dark side, his remaining limbs were severed and his entire body suffered severe burns from one of Mustafar's many lava rivers.[4][11]

Scarring legacies[]

The fallen Jedi's lightsaber was then taken by Kenobi, who left him to die on the sands[49] of the river bank and took Amidala to a base on the asteroid field Polis Massa in order for her to give birth to her twins, Luke and Leia. Alhough charred and broken, Vader was recovered by Sidious, and he was brought back to Coruscant to be rebuilt with cybernetics at[4] the Grand Republic Medical Facility[11] with the technology of the acclaimed scientist Cylo,[50] becoming encased in a suit of terrifying black armor.[51]

Despite his survival, the events of Mustafar haunted Darth Vader throughout the age of the Empire, affecting the Sith's performance as the Emperor's[52][53] primary enforcer.[54] Seldomly, stories circulated amongst Mustafarians of a great Jedi duel on their world, although no evidence was given for such tales.[22] Nevertheless, Mustafarians had knowledge of the former Jedi who slaughtered the Separatist leaders and nearly killed the boy Kakan and the miner Lellis, and whilst some thought that the fallen Jedi Knight was gone, some thought that he still remained in the mists of Mustafar. By the reign of the Empire from Darth Vader's castle years later, Lellis realized that his kind lived in the shadow of the fallen Jedi Knight, of Vader, since the fall of the Separatists.[27]

Vader's domain[]

Sanctum of the Sith[]

"When you arrive on Mustafar, find the place where the dark side calls to you. Draw upon the energy there—combine its power with your own. Then… use it."
―Darth Sidious, to Darth Vader[src]

A short time after his loss to Kenobi, Vader returned to Mustafar under instructions from his master Darth Sidious. Vader was to bleed a kyber crystal he had obtained from the Jedi Master Kirak Infil'a, who he killed, in order to gain a crimson crystal for his new Sith lightsaber. He traveled to a cave strong in the dark side of the Force[33] that contained the shrine erected by the ancient Sith[7] and poured all of his pain and anger into the crystal, making it sing a hymn of darkness. With this new weapon, Vader returned to his master, and was believed by Sidious to be one step closer to becoming a true servant of the dark side.[33]

Vader was later tasked by his master with hunting down surviving Jedi, and was sent to capture the former Jedi Chief Librarian Jocasta Nu at the Coruscant Jedi Temple. Master Nu possessed a memory crystal given to her by seekers of the Jedi Order that contained a list of potential Jedi Initiates from throughout the galaxy. After the new Sith apprentice took the list from a captive Nu, the latter told him that the Emperor's true purpose was to use it to create more agents like Vader, and the Jedi questioned what Vader truly desired while the Sith read the list. As seen by Vader, the list contained the names and locations of Force-sensitives, including Nik Lowe on Mustafar. Conflicted, Vader killed the librarian and destroyed the memory crystal, reporting back to the Emperor that he found nothing of interest on Nu.[55]

Vader bled his new kyber crystal until it shone crimson.

Over a year after the battle against his former friend on Mustafar,[56] the memory of Darth Vader burning on the volcanic slopes of Mustafar resurfaced in Obi-Wan Kenobi's thoughts along with other past happenings. Despite the pain inflicted by the memories of the past, Kenobi willed himself to let go of the series of events that led to the traumatic confrontation on Mustafar. Although the exiled Jedi still clung to his own master, his hold on his past was loosened, and Kenobi was able to focus and eventually succeed on his mission to watch over Luke, the son of Anakin Skywalker; by letting go of Mustafar and other past occurrences,[57] Obi-Wan Kenobi was able to instruct the boy in the ways of the Jedi, guiding the young Skywalker as the latter went on to help restore balance to the Force and bring down Darth Sidious' empire.[58]

Although Sidious had lost his original facility during the Clone Wars,[15] he soon built additional installations on Mustafar where he continued to abduct Force-sensitive infants. Over time, he manipulated these children and molded them into members of the Inquisitorius,[59] dark side agents trained by Darth Vader.[60] Sidious stole the childhoods away from these individuals, turning them into hunters of the Jedi they may have otherwise become.[59]

Vader's plans[]

"You created this design, in your last body. Tell me what it is."
"The door to the dark side is locked. This is the key. Your beloved waits for you there, Vader. My fortress will tune the energies of the locus. It is your first step towards using the power of the dark side to pierce the veil of time, between life and death."
―Darth Vader and Momin, on the design of Fortress Vader[src]

Fascinated by the power he tapped into in the Sith cave on Mustafar,[37] and associating the world with his rebirth and personal connection to the dark side,[51] Vader requested that the world be given to him by his master[37] around 14 BBY,[61] believing that the planet held the key to seeing his deceased wife once again. Gifted with a Naboo starship, an ancient Sith mask, and a team of top Imperial architects, Vader departed Coruscant for his new home. The Sith Lord entered the planet's violent atmosphere unshielded, causing severe damage to his vessel and casting a streak of fire across the smokey sky. His entry was witnessed by the Mustafarian Father Kkkt, who warned his clanmate Zzzs that the fireball was an omen of events to come.[37]

Vader meditates in the Sith cave.

Landing near the Sith cave, Vader meditated within its dark walls, leaving the Emperor's architects, Colonel Alva Brenne and Lieutenant Roggo, to draw up plans for a personal base Vader could inhabit. Brenne scouted the terrain of the planet, believing that, although Vader was seemingly impossible to satisfy, she could manage to design a home suitable for the Dark Lord. Unbeknownst to the architects, the mask that Sidious had gifted Vader was possessed by the spirit of Darth Momin, a heretic artisan from the Sith's forgotten past. The mask took control of Roggo, using his body to kill Brenne and create its own designs for the base.[37]

Vader confronted the spirit, killing its host body and demanding that it give him answers. The spirit introduced itself as Momin and offered to help Vader construct a fortress that would harness the energies[37] of the dark side locus below the cave to open a door into the Force itself;[51] through and beyond the limitations of time and space. After abducting the Mustafarian Sssp to serve as Momin's new body[37] and taking command of a vast Imperial construction force on the Gahenn Plains, the two Sith Lords began their work on what would become Fortress Vader.[62]

Portal to the past[]

"I have been in contact with the other clanholds. We are not the only one affected—the entire planet screams at what the dark one is building on the Gahenn Plains."
―Father Kkkt[src]

Momin's imperfect designs caused chaos on Mustafar.

The construction of the fortress was not a simple task. Over the course of eight attempts[51] with at least five separate designs, Momin struggled to find the perfect structure that could correctly channel the dark side. The energy Vader exerted while attempting to open a rift in the locus caused electromagnetic storms to rage across the planet, throwing the world's creatures into a frenzy and casting the Mustafarian people into disarray. Father Kkkt, realizing the danger Vader posed to his world, rallied the clanholds across Mustafar prepared to mount an attack on the Imperial intruders.[16]

Upon the completion of Momin's ninth design[16] in 12 BBY,[63] Vader was finally able to reach through the Force and open a pathway into time, but he was interrupted in his moment of triumph by Kkkt and his forces. With the Dark Lord distracted, Momin entered the portal and claimed his original body, betraying Vader.[16] Kkkt's army had initial success in pushing back the Imperials, attacking them with surprise tactics. Vader, however, soon arrived and rallied the stormtroopers to double their efforts. Recognizing Vader as the Imperial leader, Kkkt lead the Mustafarians in powerful usage of the Force, drowning the enemy forces in a vast flood of lava. Vader was able to retreat into the fortress, summoning his own massive force of energy to destroy the Mustafarian attackers.[64]

Returning to the inner sanctum, Vader confronted Momin, who mocked the cyborg Sith for his failures in service to the dark side. Using Momin's hubris against him, Vader crushed and killed the resurrected artist. With no one to stop him, he entered the portal,[64] encountering visions of his past and future, including his beloved wife, Padmé. Upon witnessing what Skywalker had become, however, the vision of Amidala ran from Vader, choosing to kill itself.[65] Frustrated with the dark visions clouding his attempts, Vader retreated and crushed the altar in the Sith cave, destroying the portal[51] and accepting that the truth he encountered was exactly what he needed.[65]

Mustafarian revolts[]

"This is an Imperial facility."
"And this is our world. A world with secrets that I have vowed to protect at all costs."
―Rersey and Sssl[src]

According to a tale, an Imperial officer was driven insane by Mustafar's lava fumes and submitted to Vader as the servant Vaneé.

The Black Sun moved off of Mustafar to a lower-profile world after the Empire established a garrison there.[7] Following Kkkt's failed attack and the completion of Fortress Vader,[28] according to a story told years later by the Mustafarian Lellis, Darth Vader sought candidates for a servant who would attent to his needs, searching for months until the human named Vaneé came into his service. During Vader's search, an Imperial officer was sent from Imperial Command to Mustafar by Moff Seward, and tasked to handle an outbreak of insanity amongst Imperial Lava Troopers assigned to Fortress Vader. On Mustafar, the inspector found that the troopers had inhaled toxic fumes from the planet's depths that gave one illusions of fears and doubts, and thus entered Vader's castle to speak with Darth Vader himself with the intentions of resolving the matter. However, Vader, bathed in his bacta tank, instead forced the officer to inhale the fumes and confront his fears by holding him in place telekinetically, refusing to let the human go and stating that the fumes could be filtered later. Face with the illusions caused by the Mustafarian fumes, the inspector denied their existence and began to laugh, laughing for days until he took advice from the voices by his head and submitted to Vader as the servant named Vaneé.[27]

Eventually, years before the Battle of Endor[27] of 4 ABY,[41] the lava fumes leaking into Vader's castle were blocked off.[27] During the early days of Vader's reign over the planet, Vaneé witnessed the efforts of a second force of Mustafarians to push the Sith away from their homeworld. The group, led by Criakan, desired vengeance for their slaughtered kin and stormed the fortress in a surprise attack. Surrounding Vaneé, Criakan and his forces intended to show no mercy to the Imperials, but were shown the same respect by Lord Vader, who cut them all down before they could burn down the castle.[28]

Darth Vader fights Priestess Sssl's forces at Fortress Vader.

Sometime later, during a visit from the Emperor's adviser Rersey, a third attack on Fortress Vader was undertaken by Clan Rrrt's Mother Sssl, a Mustafarian priestess who could force her will upon others by subjecting them to a mind-altering plague. Sssl's forces soon overwhelmed the Imperials, infecting Vader's soldiers and turning them against the Sith. Although Sssl had only intended to scare off the invaders, her plans changed when the Dark Lord himself was seemingly infected. In reality, Vader's mechanical body was immune to the plague, allowing him to feign subservience and draw the priestess out. Using a mind trick, Vader forced Sssl to command her own forces to drag her into the lava, a sight that caused the adviser Rersey to lose his sanity. Vaneé praised his master and noted that the Mustafarians would fear Vader's name in the future.[24]

Fire across the galaxy[]

"Whoa. Whoa, that looks like—that looks like Mustafar. Mustafar's a mining planet. Why are the Imperials taking us there?"
―ZO-E3, to her captain[src]

Joining Vader on his new home, the Galactic Empire took control of Mustafar[30] and maintained secret facilities on the world where Jedi survivors of Order 66 were interrogated and executed, though the lava planet was still only publicly notable for its mining operations.[10] Rumor had it that Darth Vader carried out these interrogations, torturing the Jedi for any useful information before their execution.[66] Additionally, both Vader and Sidious returned to the planet, using it as a focus for meditation on the power of the dark side of the Force.[11] The latter half of the Imperial Era saw outsiders coming to Mustafar as conflicts arose against the rule of the Galactic Empire. With the establishment of Darth Vader's castle, both the Empire's leaders and rebels came to the planet as a result of the Imperial presence.[67][68][17]

In around this time,[69] the term "Mustafarian Special" was used by smuggler Lando Calrissian and his first mate, L3-37, to refer to a starfighter maneuver that involved great speed and surprise, and which ensured at least one side of a starship confrontation "end[ed] badly." L3-37 explained that the tactic was named such in reference to the eponymous lava planet's fiery nature.[70]

Also around the time of Fortress Vader's construction,[71] after being attacked by a trio of cadets when he was studying at the prestigious Royal Imperial Academy on Coruscant, the Chiss Mitth'raw'nuruodo recommended to the Imperial Academy's commandant, Deenlark, that his assailants should be transferred away. In response, Commandant Deenlark snorted with derision and asked if the Chiss wished to have the three attackers transferred to Mustafar as punishment. However, Mitth'raw'nuruodo suggested that the three train instead as starfighter pilots at[67] the elite Skystrike Academy on Montross.[72]

A smuggler and ZO-E3 arrive at Mustafar.

At some point prior to the Battle of Yavin, a smuggler and ZO-E3 were forcefully taken to Mustafar, taken out of hyperspace by an Interdictor-class Star Destroyer. While the duo was present, the smuggler was discovered to be a descendant of Lady Corvax, a ruler who once presided over Mustafar. As the smuggler and ZO-E3 made their escape, they attempted to retrieve the Bright Star to restore Mustafar to its former state.[12] The smuggler briefly trained under Vader, learning of their Force sensitivity, though Vader later betrayed the smuggler, taking the Bright Star in an attempt to revive Padmé Amidala.[20] The smuggler prevented this, staging an escape from Fortress Vader and destroying the Bright Star. This act allowed Mustafar to begin replenishing the ecosystem it lost long ago.[34]

Galactic war on Mustafar[]

Rebels in peril[]

Thus falls the Inquisition[]

Imperial Star Destroyers stood watch over Mustafar.

The strict travel restrictions imposed by the Empire made it difficult for the Mining Guild to make Mustafar profitable.[2] While the world remained under heavy Imperial guard, mining operations on the planet eventually ceased.[73] Four years before the Battle of Yavin,[41] an Imperial fleet commanded by Grand Moff Wilhuff Tarkin aboard his personal Imperial I-class Star Destroyer, the Sovereign, orbited Mustafar. When the Spectres rebel cell leader and Jedi Kanan Jarrus was captured, he was brought aboard the Sovereign.[10]

When the Spectres attempted a mission to rescue Jarrus under the leadership of Hera Syndulla, the Sovereign was destroyed during a duel between Jarrus and the Grand Inquisitor when the latter's lightsaber was cut in two by Jarrus and fell into the ship's power core, sending the vessel falling towards the lava fields below. With the aid of Phoenix Cell, a resistance group[68] affiliated with a growing network of rebels formed by Senators Bail Organa and Mon Mothma,[74] the Spectres successfully extracted their Jedi leader and joined the larger Phoenix Cell.[68] The skirmish over Mustafar thus became one of the earliest rebel victories in the Galactic Civil War against the Empire.[10]

Due to their Jedi members, and having become a part of Bail Organa's rebel network, the Spectres began to work with the former Jedi Ahsoka Tano[68] on Jedi business.[75] In around 4 BBY and 3 BBY,[76] Tano reported to the Spectres' Kanan Jarrus that in her search for information regarding the Sith Lord[75]—who, unbeknownst to the rebels, was Darth Vader, the former Anakin Skywalker and master of Ahsoka Tano[77]—who attacked them over the planet Lothal shortly before, she had been monitoring transmissions from Mustafar, and despite information on the Sith Lord remained elusive, she had gathered more intelligence on the Empire's Inquisitors.[15]

The former Jedi divulged her findings of that their secondary mission was to "make retrievals," along with two sets of coordinates she decoded from the Mustafar transmissions. Informed of the news, Kanan Jarrus and Ezra Bridger investigated one of the coordinates given to them by Ahsoka Tano. Together, they uncovered the Inquisitors' plot to kidnap Force-sensitive infants on Takobo,[75] similar to Darth Sidious' attempt to take Jedi potentials to Mustafar for reconditioning that Tano, then former Padawan to Anakin Skywalker, foiled alongside her master during the Clone Wars.[15]

Fortress of terror[]
"I thought I was doing the right thing. I thought the planet was our only hope. I had no idea what terror lay ahead…"
―Lina Graf[src]

Later in the war between the Empire and the Alliance to Restore the Republic, newly-formed from various rebel cells by Mon Mothma, a crew of rebels led by Commander Lina Graf was attacked by Imperial forces, and their ship, the Auric, was heavily damaged. They were forced to crash-land on Mustafar, a planet that Graf hoped would lead to her crew's salvation. Surrounded by lava, the rebels abandoned their ship and began toward the only structure in sight, Vader's fortress.[73] They did not make it far before being attacked by Mustafar's exploding beetles. After defeating the beetles and arguing over the best course of action, Graf and her crew were cornered by a squad of Imperial Lava Troopers.[25] Escaping the troopers, the group entered the fortress but soon became separated in its dark halls. Alerted to their presence by his aide Vaneé, Vader confronted the rebels,[78] capturing Lieutenant Thom Hudd[79] and destroying the bodyguard droid XM-G3,[78] though Graf and her remaining crew managed to escape Mustafar.[28] The rebels' successful escape from Vader's castle was remembered by the native Mustafarians by the aftermath of the Empire's collapse.[27]

The Auric crashes on Mustafar.

For the next several weeks,[80] Vaneé kept Hudd locked within the fortress and tortured him, all the while tormenting him with horrific tales from across the galaxy,[81] including the story of Vader's brutal murder of Sssl years prior.[24] The abuse and starvation that Hudd suffered while chained to the Sith servant's torture web was so severe that he lost enough body mass to slip from his shackles and escape his cell.[81] Hudd managed to send a distress signal to the Alliance but was ultimately recaptured and sentenced to death. His execution was stalled by Graf, however, who had returned to Mustafar disguised as an Inquisitor. Although Vaneé saw through her ruse, Graf and Hudd were able to escape and flee the planet with the rest of their crew. Vader, angered at his servant's ineptitude, rigged Vaneé up to the torture web, though he allowed him to live.[24]

After gaining intel on the Empire's operations on the planet, a small Rebel force was sent by Captain Cassian Andor to infiltrate an Imperial base located near Vader's castle on the lava fields of Mustafar and steal a vital artifact to assist the Rebellion. Upon infiltrating the base, the Rebels discovered the artifact was a proto-saber, a precursor to the lightsaber. Despite the intervention of Darth Vader, the Rebels escaped with information about the ancient weapon.[18]

Crushing aspirations[]

"You seem unsettled."
"No…just pressed for time."
―Lord Vader and Director Krennic[src]

Orson Krennic arrives at Fortress Vader.

In 0 BBY,[82] the Empire completed construction on the Death Star, an orbital battle station capable of destroying a planet. After a rebel attack on an Imperial laboratory on Eadu threatened to expose the Death Star's capabilities to the galaxy at large,[17] Vader summoned the director of the project, Orson Krennic, to his fortress on Mustafar.[13] Krennic, arriving while Vader was sustained within a bacta tank,[17] was escorted into a rotunda in Fortress Vader by Vaneé to await the Dark Lord. Confronting the uneasy director, Vader admonished Krennic for his failures, using the Force to choke the aspirational officer when he requested an audience with Emperor. With his message relayed,[13] Vader watched Krennic's ship depart[83] for the planet Scarif.[13]

Despite Vader's threats, Krennic would fail in his endeavors,[17] and the Death Star was ultimately destroyed by the Rebel Alliance. Around the same time, the Rebels also destroyed the Empire's Mirkanite Mining Facility on Mustafar.[5] Additionally, the loss of the Death Star served to galvanize resistance across the galaxy, causing trouble for the weakened Empire. In response to this outbreak of rebellion, Vader was met on Mustafar by Admiral Kendal Ozzel and General Maximilian Veers. Overlooking the planet's lava fields, the trio discussed the proper route to deal with the rising Alliance, though Vader viewed Ozzel's suggestions as nothing more than excuses for incompetency. An interesting point from General Veers, however, persuaded Vader to view the rebels in a new light, prompting him to develop a different plan to cripple the Alliance.[84]

Into the fire[]

"The last time you were broken…I found you…and I rebuilt you. This time… you must rebuild yourself."
―Palpatine, to his battered apprentice[src]

Darth Sidious sent Ochi of Bestoon to recondition his apprentice, Vader, on Mustafar.

In 3 ABY,[41] Vader attempted to turn his son, Luke Skywalker, to the dark side during a duel over the planet Bespin. After Skywalker fled, however, Vader temporarily abandoned his duties to the Emperor, embarking on a personal quest that led to the discovery of a rebel cell led by Sabé, the former decoy of Padmé Amidala. Vader allowed the rebels to live, a decision which convinced Sidious that his apprentice was in need of a reminder of his place. The Sith Emperor mutilated Vader on Coruscant, ripping his cybernetic limbs from his body and strangling him as he had done to men like Krennic in the past.[85]

Not finished with his lesson, Sidious took his student back to Mustafar. He had Vader's personal guard of death troopers drag the crippled Sith to the spot where Kenobi had defeated him decades ago, leaving Vader to fend for himself. Warned by his master that there would be consequences should he use the Force to save himself, a one-armed Vader crawled along the lava banks and retrieved his fallen lightsaber before slowly making his way to the ruins of the Techno Union installation. Sidious watched from Vader's Lambda-class shuttle as the broken man pulled himself across the sand. Although Mas Amedda, the Emperor's Grand Vizier, warned that the Dark Lord planned to kill his master, Sidious was unconcerned and sent his Sith assassin, Ochi of Bestoon, to turn Vader's anger into pain.[85]

Having reached the Techno Union installation ruins, the very building where he had slaughtered the Separatist Council decades prior, Vader repurposed surrounding Separatist droid parts as his own limbs and confronted Ochi, overpowering the assassin and demanding him to reveal Darth Sidious' plans. As Vader did so, the Eye of Webbish Bog called out to the Sith Lord,[86] who, despite being deprived of his chest box and lightsaber by Ochi, fought his way through hordes of lava nymphs and lava fleas as well as a roggwart to reach the Eye's cavern. As Vader did so, he was tested by the Eye and reminded of his inner conflicts between his chosen Sith and Jedi destinies as well as between his personal desire of power and his need for his son. During Vader's journey to the Eye's lair, Sly Moore and a group of death troopers spoke to Ochi of Bestoon, reminding the assassin to abide by the Emperor's directives.[87]

At the end of Vader's trek to the Eye, the latter gave the cyborg a wayfinder and allowed him to leave the cavern to rejoin Ochi. Once outside, Vader made his way to the green Jedi starfighter that he took to Mustafar at the end of the Clone Wars,[87] repairing the ship until Ochi reappeared with the Droid Crush Pirates of Bestoon. Having been promised Vader's cybernetic parts by Ochi, the army of droid pursued the Emperor's enforcer until they found that his parts were no more special than their own. In the midst of a quarrel with Ochi about their deal, the droids were interrupted by Vader, who took down the machines for use in retrofitting his green starfighter and an escape pod, which he locked Ochi in after forcing the assassin to activate his wayfinder. In his determination to find the Emperor's secrets, Vader bound the pod to his starfighter and set off to the wayfinder's coordinates, reaching the vicinity of Exegol by way of hyperspace.[88]

With Ochi in tow, Vader confronted Sidious on Exegol, an ancient Sith world which housed hundreds of Sidious' secret experiments and weapons. The Emperor reminded his wayward apprentice that he left him weak and broken on Mustafar's burning shores, and asked Vader what he learned from the experience. However, Vader remained rebellious, stating his intention to make his "master" fear him. Despite Vader's efforts, he was overwhelmed by Sidious' power. Terribly pained but having experienced a vision of his son telling him it was his destiny to destroy Sidious, Vader accepted his master's dominance over him for the time being before leaving Exegol with him and Ochi.[89]

Ashes of Empire[]

Lingering darkness[]

"It is not over. Not yet. Not while you can bring him back…your master will return to the fires of Mustafar and, this time, will be made whole… Vader triumphant. Vader supreme. Vader… reborn!"
―A voice speaks to Vaneé[src]

Toward the end of the Galactic Civil War, Vader was saved by his son Luke Skywalker's selfless compassion and in turn sacrificed himself to destroy the Emperor[90] aboard the second Death Star during the Battle of Endor in 4 ABY.[41] Having re-embraced his identity as Anakin Skywalker as he succumbed to the injuries inflicted upon him by his late Sith Master,[58] Vader died leaving his fortress without a host.[27] After the battle, pilot Wedge Antilles went on a scouting mission to suspected Imperial planets. He reported back to the New Republic when he was on Raydonia before going missing above the planet Akiva. Due to its proximity to Raydonia, Admiral Gial Ackbar sent a scout to Mustafar, as well as to Tatooine, Dermos, and Geonosis, while two scouts were sent to Akiva.[66]

Following news of Darth Vader's death over Endor that was broadcast by the Rebel Alliance, Mustafarians gathered around the fortress' vicinity in celebration of the fall of the Empire. Lightning storm clouds and lava on Mustafar stirred around Vader's castle, howls sounded in the night, and cries echoed across the lava plains. The Mustafarian boy Giggek recognized that his kind were not truly free as long as they lived under the shadow of Vader's castle, and so resolved to rid the land of Vader's curse by bringing the castle to ruin. Along with Tuttel, Giggek acquired detonators from a store of equipment from the obsidian mines belonging to Tuttel's uncle, Lellis. However, the latter forbid the young boys from entering Vader's castle for the reason that it was lethal and evil, telling the story of how Vaneé came into servitude under Vader and further speculating that the young Mustafarians were only wanting to be figures of legends.[27]

Two young Mustafarians ventured into Fortress Vader despite being cautioned against doing so by Lellis.

Nevertheless, Giggek led Tuttel into Vader's castle by way of lava flea, venturing in to find a pit trapping Vaneé, the servant of Vader and the self-styled "one true Acolyte of the Beyond" who was detained by Vader there some time ago. Rescuing the Acolyte in hopes of not bringing death upon anyone in the process of destroying Vader's castle, Giggek was at once betrayed by Vaneé, who dropped the boy down the pit in hopes of bringing death to those who sought to tarnish his master's legacy. However, after instructing his Mustafarian companion to flee, which Tuttel did with their lava flea, Giggek ignited his explosives through a remote detonator, and although the blast did not bring down Vader's castle, Vaneé was buried in black sand. However, the Sith servant survived. A voice familiar to Vaneé told him not to fear, and assured its servant that he could return Vader to the fires of Mustafar and be made whole.[27]

Mustafar grew in obscurity in the decades that followed, and Vader's castle eventually fell into ruins.[7] Thanks to the destruction of the Bright Star,[34] Mustafar's ecosystem began to be healed. Several individuals from off-world also visited the planet,[7] including the spy Vi Moradi[91] as well as the historian and adventurer Eloc Throno, who wrote of the world in Volcanic Planets: Your Guide to the Galaxy's Hottest Destinations, one of the many travel guides he wrote throughout his career.[92] By 35 ABY,[38] many pilgrims had come to the ruins of Vader's castle seeking to tap into the Sith Lord's dark power. One group of pilgrims,[7] the Alazmec of Winsit, guarded the castle ruins as well as its secrets jealously,[10] colonizing the nearby Corvax Fen—a rich soil ground—and planted a forest of irontrees in the hopes of restoring Mustafar's once lush landscape from centuries ago, believing that the soil was soaked by the tears of Lady Corvax.[7]

Pathway to the Sith Eternal[]

"I must warn you, our fiery planet burns away deception. If you proceed down this path, you will encounter your true self."
―Eye of Webbish Bog, to Kylo Ren[src]

Mustafar was visited by Kylo Ren, Supreme Leader of the First Order, years after the death of his grandfather, Darth Vader.

After the destruction of the First Order's Starkiller Base and the Battle of Crait[2] in 34 ABY,[93] the Weequay pirate Hondo Ohnaka wrote about Mustafar in his book titled Galactic Explorer's Guide.[2] During the ongoing war between the First Order and the Resistance[94] in 35 ABY,[38] First Order forces arrived at the planet via the Resurgent-class Star Destroyer[94] Steadfast[7] following a mysterious broadcast by the resurrected Darth Sidious.[94] Knowing that Mustafar was once ruled by his grandfather, Darth Vader, Supreme Leader Kylo Ren regarded it as hallowed ground—the place where Anakin Skywalker died and a Dark Lord of the Sith was born.[35]

Due to the wayfinder of Vader being located in the castle's ruins, the Supreme Leader and his stormtroopers attacked the cult of Alazmec colonists,[94] who were sworn to protect the fen surrounding the ruins of Vader's castle.[7] Having arrived at the planet in his TIE whisper,[39] Ren slaughtered several cultists using his lightsaber in search of the wayfinder that would allow him to reach the planet Exegol in the Unknown Regions, where Sidious resided amongst his Sith Eternal followers,[94] while General Armitage Hux and Allegiant General Enric Pryde observed Ren from afar.[39]

Ren killed the Alazmec colonists before claiming the Sith wayfinder that once belonged to his grandfather.

After defeating the cultists, Ren traveled through the forest and arrived at a small lake, where he encountered a spider-like creature sitting atop a blind giant in the water. The spider creature, identifying itself as the Eye of Webbish Bog, informed Ren that it knew what he sought, but it warned him of encountering his "true self" if he were to continue down his current path. When Ren did not respond, the Eye relented and rewarded the Supreme Leader for his victory over the Alazmec, pointing the way to the Sith artifact.[39] Ren was guided by wisps of the dark side and came to an altar surrounded by the ruins of Vader's fortress. Using the Force, he tore open the structure and finally discovered the wayfinder.[35] The Eye of Webbish Bog and the giant then disappeared into the lake, leaving Ren alone with the artifact. Knowing that he would not be the only one to travel to Mustafar in search of the object, he and the rest of the First Order forces departed the planet.[39]

Inhabitants[]

The Mustafarians[]

"Mustafar is our world. We have already lost so much. The lifefires barely burn. It is time to come together…and save what is left."
―Father Kkkt[src]

However harsh and volcanic, Mustafar was not devoid of life.

Mustafar was the homeworld of the Mustafarians, a species primarily concerned with their own advancement and survival[22] that lived in underground caves created by the lava fleas that ate through the planet's crust.[29] Two races of Mustafarians evolved in distinctly different cave systems[7] in the mountains from extremophile arthropods,[11] one subspecies living near the planet's equator and the other in the north. They lived together as needed, although the geographical distance and limited desirable living space tended to limit the subspecies in their own communities.[22]

Only venturing up to the surface in order to collect valuable minerals from the lava flows, the southern Mustafarians carried out the heavy labor involved due to[29] their short and strong physiology that developed due to the relatively higher gravity of their homeland, surviving high temperatures and frequent accidents on lava flows thanks to their thick carapaces, while the tall and slender northern Mustafarians had keen, faceted eyes which easily spotted flaws in ore and machinery alike,[22] and who acted as guards and expert riders of the lava flea, a creature that the natives made their armor from the heat-resistant shells of.[29]

Chitinous exoskeletons and low-water biology allowed Mustafarians to withstand the intense heat of their homeworld, though they still required insulated clothes and breathing apparatus to work on the surface.[11] The native Mustafarians developed and sought technology for survival more so than most other species, and some enhanced themselves with cybernetics to better carry out common tasks and withstand the harsh environments of their homeworld. Having learned from tragic experiences, Mustafarians did not trust imported technology until they themselves modified and adapted them to Mustafar's climes. While the two Mustafarian subspecies lived together as needed, the geographical distance and limited desirable living space tended to keep them in their own communities,[22] though it was not unheard of for clans to be comprised of both northern and southern Mustafarians.[37]

Mustafar's volcanic crust allowed for the creation of Mustafarian Lava Buns.

The Mustafarians grew few crops, as the lack of water meant traditional farms, even when located underground, could not be sustained;[22] water had to be imported to Mustafar.[29] Nevertheless, despite the what little life Mustafar had compared to other worlds, various types of edible fungi and domesticated herds of large insectoid creatures made up much of the Mustafarian diet, and unlike other hotbeds of industry in the galaxy, Mustafar was largely self-sufficient in regards to its food supply.[22] Southern Mustafarians made Mustafarian Lava Buns by placing sweet balls of dough upon the planet's volcanic crust, heating it up to create a red bread with a cracked and blackened exterior. The Artiodac chef Strono Tuggs witnessed the production of the baked goods during a visit to Mustafar, learning the recipe to the buns in the process. Tuggs later served the buns at his mobile restaurant on the Outer Rim planet Batuu after the fall of his previous place of employment on Takodana[95] in 34 ABY.[41]

Though they typically inhabited natural caverns and abandoned mines, Mustafarians built outdoor structures as necessary, including saucer-shaped buildings at and near active mining sites. Their structures were strongly reinforced and armored to protect them from natural disasters, making their larger facilities fortresslike in construction and durability.[22]

The Mustafarian people shared a deep connection with their planet,[37] seeking harmony with the natural forces that sculpted their homeworld.[2] Surrounded by volcanic magma, their culture was tied to the ebbs and flows of the lava on which they lived.[37] In the difficult times of the Empire, history and lore of Mustafar lived on in a Mustafarian leader known as the Priestess, who provided guidance and invaluable information to natives and visitors alike.[96] The natives lived in clans,[2] and members of Father Kkkt's clan spoke of "lifefires" and "endfires" while discussing the arrival of Darth Vader; Kkkt himself used the Force to form a symbol within a lava river, which he interpreted as an omen of the planet's future. The Mustafarians had a strong desire to protect their homeworld, banding together[37] on multiple occasions to defend against Imperial forces.[28] They had a special relationship with the other life on Mustafar; lava fleas were used to jump over lava flows in a rite of passage, and kahel cave fungi served as the inspiration for Mustafarian architecture.[11] The Priestess spoke of a being known as Sleeper, whom she prayed to after encountering a deceased darkghast.[20]

The Mustafarians were fierce defenders of their planet.

Mustafarians were politically organized in accordance with the caverns and communities they inhabited, though they had little in the way of a central government. However, some trusted leaders were allowed to make deals with offworlders in order to help ensure their survival and quality of life. As a result, the Mustafarians fell under the sway of the Techno Union and later the Mining Guild,[22] serving them as ore scouts, miners, and refinery laborers. Though they resented the presence of offworlders,[2] Mustafarians were generally willing to tolerate a degree of outside political influence as long as it furthered their own cause. Because of the demanding environment of their world, Mustafarians were generally insular and disinterested in galactic affairs, few regarding offworlders with much curiosity. Their focus on the advancement and survival of their own species overrode other concerns, a result of inhabiting a world that demanded so much in order to so much as continue living.[22]

Mustafarians spoke a language of the same name,[28] which allowed for the precise expression of concepts related to naturals features above and below ground, especially phenomena that were deceptively dangerous. Though the Mustafarian subspecies spoke different dialects, any two individuals could communicate on a functional level despite differing terms and cultural concepts. Though they were also capable of speaking Basic and other common galactic languages, most that did not work with the Mining Guild or deal with outsiders by necessity did not bother to learn Basic. However, Mustafarians that lived or traveled offworld almost always spoke Basic and sometimes the language of their trading partners. Due to their history with the Techno Union, they were more likely to know languages regularly used among former Separatist worlds.[22]

Mustafarian travels off-world were driven by business pursuits and trade negotiations, and were generally restricted to the Outer Rim. So long as their safety or that of their companions was not threatened, the species was disinterested in galactic affairs, which made them foremost disinclined to leave their homeworld. For Mustafarian merchants and Mining Guild personnel, regular trips were made off-world to trade for upgrades in protective technology and equipment, as well as to deliver ores to buyers. However, there were some Mustafarians who sought full-time employment off-world. They found most inhabited worlds cold, yet relished the relative safety.[22]

Invaders and colonizers[]

"We bow only to one, the Dark Lord, the true father and ruler of the galaxy. Vader."
―Kylo Ren's translation of an Alazmec warning[src]

Black Sun's Falleen leadership was based out of Mustafar until the Empire established a garrison on the planet.

The Techno Union, a guild of technology firms led by Skakoans like Wat Tambor,[97] came to value the lucrative minerals of Mustafar and set up operations on the planet.[11] The offworlders introduced heavy industry, and were welcomed by the native Mustafarians in exchange for access to mining droids and heavy-duty speeders.[22] However, the natives became subjugated, being put to work in the Techno Union's mining operations[11] and charged rent on their own planet.[7] Management staff of the Union utilized native buildings throughout their operations and provided a refuge for the Separatist Council during the final days of the Clone Wars.[11]

Aside from the native people and the Techno Union, Mustafar was also inhabited by Falleen,[14] tall and muscular repto-mammalians native[98] to the Mid Rim[8] planet of the same name[98] that controlled the vast Black Sun criminal empire. Humanoids with distinctly nonhuman appearances, they had ridged skulls,[99] scaly green skin,[98] and exuded powerful pheromones to attract mates.[19]

The Sith Lord Darth Vader called Mustafar his home during the Imperial Era. Originally coming to the planet in hopes of resurrecting his deceased wife,[37] Vader lived on the volcanic world for over a decade, utilizing its scorched earth to conduct his personal business.[17] Stories of the Jedi who died by his hand on Mustafar became synonymous with the planet itself.[68] During his visit to Fortress Vader, Director Krennic theorized that Mustafar was Vader's homeworld, imagining that the Dark Lord's cybernetics were designed to allow him to survive while away from the molten planet.[13] The Sith Lord's occupancy was known to others in the galaxy as well. After discovering that Mustafar was Vader's domain, the Naboo resistance group known as the Amidalans deduced that he was responsible for Padmé's death and plotted to kill the Dark Lord to avenge the fallen queen.[100]

Vader spent time in bacta tanks to tend his grievous wounds.

As Darth Vader established his personal headquarters on Mustafar, the forces of the Galactic Empire followed.[37] The Imperials' occupation of the planet forced Black Sun[7] and the Techno Union to abandon their operations, with the Mining Guild taking over what remained.[2] Within both Vader's fortress[28] as well as other installations, the Imperial Army had a sizable presence on the world,[18] enough that the native population sought to remove them from the planet.[24] Stormtroopers guarded Imperial interests on Mustafar;[18] among their ranks were Lava Troopers, specialized soldiers that operated within the planet's volcanic environment.[28] During this period, the agents of the Inquisitorius trained in their own fortress on the nearby moon Nur, keeping close to their master Vader and his castle.[101]

Many groups of cultists came to Mustafar in the decades since Vader's passing, seeking the power that the Sith Lord once tapped into on the planet. One of these groups, called the Alazmec of Winsit, gained control of the Corvax Fen, a land of fertile soil. They planted several irontrees in the hopes of restoring the landscape that was once present centuries ago, and were devoted to guarding it from outsiders such as Kylo Ren and the First Order.[7]

Other inhabitants[]

"Lady Corvax abided here with her husband Sir Dorwin, living in peace with my people."
―The Priestess speaks to the descendant of Lady Corvax[src]

Lady Corvax was responsible for Mustafar's devastation.

In the planet's vibrant past, the Mustafarians shared the world with Lady Corvax and her husband Dorwin, humanoids who lived peacefully with the natives. Dorwin fell in battle,[12] but he did not die; instead, he was cursed to exist between life and death on the ruined world[20] until he was freed by Corvax's descendant.[34]

The ancient Sith established a presence on Mustafar, hoping to reap the benefits of the dark world and obtain immortality.[7] At some point, the Sith Lord Momin found himself on Mustafar, and later, during the Imperial Era, recalled that long ago time.[62]

Two mysterious beings resided within a small lake and guarded the path to the ruins of Vader's castle; one, a blind giant, and the other, an individual known as the Eye of Webbish Bog, were locked in a symbiotic relationship.[39] Spoken of in the myths of the Mustafarians, the Eye was defended by the Alazmec of Winsit.[35]

Locations[]

Settlements[]

Vos: "Where can we get a drink?"
Mustafarian: "The Last Resort."
Ventress: "That the best bar in town?"
Mustafarian: "Only bar in town."
―Quinlan Vos and Asajj Ventress ask a local for directions in Zitontown[src]

The native Mustafarian populace, including both the Northern and Southern sub-species, took up residence in underground caves that were made by lava fleas munching through Mustafar's crust.[29] Despite this, the two peoples lived in distinct underground cave systems, which resulted in their evolution into two sub-species.[7] The Mustafarians' underground buildings were designed in the shape of kahel cave fungus,[29] which was highly symbolic in Mustafarian culture.[11]

Due to the planet's fiery surface, outdoor structures were built where necessary—usually at and near active mining sites[22]—and buildings on Mustafar were held up by stem-like gravity supports.[29] Its capital city was Fralideja, one of the few remaining Mustafarian settlements at the time of the Clone Wars. A cataclysmic eruption that occurred centuries before the war's end almost destroyed the entire local population. The city and its surrounding structures were of Mustafarian architecture: mushroom-like structures with a habitation dome raised from the scorched ground, based on the shape of the local culture's highly symbolic kahel cave fungus.[11] The saucer-shaped structures were strongly reinforced and armored against natural calamities, with larger facilities on Mustafar becoming fortresslike in construction and durability.[22] Although Fralideja and its surrounding buildings that numbered several appeared modular, the structures varied in size and elevation.[11]

Another settlement was a mining town[19] known as Zitontown,[2] named for Ziton Moj, a senior Black Sun Vigo who rose to leadership of the organization during the Clone Wars.[102] Located outside of town was as a fortified[19] cliffside facility[103] that served as the organization's headquarters during the conflict.[104] The installation's architecture was distinct from other facilities located on Mustafar.[105] Miners from a variety of species lived and worked in Zitontown, most of whom were poorly nourished in comparison to the Falleen that inhabited the Black Sun fortress. In addition to the fortress, Moj also possessed a palace.[19]

Structures and installations[]

"Few people have the honor of seeing Lord Vader in his sanctum. I suggest you keep all you witnessed to yourself."
―Vaneé, to Orson Krennic, upon the latter's arrival at Fortress Vader[src]

Darth Vader's Fortress on Mustafar

During the Clone Wars, Darth Sidious secretly maintained an old mining outpost. He planned to use it as a facility to train Force-sensitive children to become Dark Side spies. He tasked the bounty hunter Cad Bane with kidnapping children and delivering them to the facility for their training. However, it was destroyed in 21 BBY by Sidious' crew of nanny droids after Anakin Skywalker and Ahsoka Tano rescued multiple kidnapped children from the facility.[15]

The Techno Union maintained multiple mining operations on Mustafar, including a complex built into a lava-filled mountain and a nearby residence for technicians and mine management staff located opposite to the capital city Fralideja. Around the area was a molten rock plain with erupting lava geysers that were repressed by the facility's repulsor fields. In addition to containing a secret command facility, the structure served as cover for a Techno Union droid production operation concealed inside the mountain upon which the mine sat, manufacturing battle droids[11] for the Separatist Droid Army.[22] The repulsor fields that protected the complex were inadvertently deactivated during the duel between Obi-Wan Kenobi and Darth Vader and the facility soon fell into ruin.[11]

Fortress Vader was an obsidian tower built by the eponymous Sith Lord as a personal retreat during the Imperial Era.[106] With a gap dividing the central body of the tower in the middle that resembled tuning forks, the fortress harnessed the surrounding lava for energy. It was also designed to channel the dark side's power,[10] and, along with being near the site of the Sith Lord's duel against his former master Obi-Wan Kenobi,[106] it was located above an ancient Sith cave to provide a more powerful locus of the dark side for Darth Vader to draw upon.[10] When visiting the fortress, Imperial officers were intimidated by the surrounding environments, and the treacherous landscape of Mustafar worked to remind them of their place.[51]

Other landmarks[]

"Mustafar is not like other planets. It is unique. Deep beneath its surface rests a locus for the dark side of the Force."
―Darth Sidious, to Darth Vader[src]

The Sith cave housed a powerful heart of darkness.

Formerly a part of a Sith temple, the cave beneath Vader's castle contained a locus of the dark side of the Force.[51] The walls of the cave were covered in glowing runic symbols, which Vader and Momin later rearranged to focus the energies of the planet. By tapping into the dark powers of the locus, an individual could open a rift between time and space to enter a portal through the Force.[64] Darth Vader also forged his first red lightsaber at the cave, and Snoke, the First Order Supreme Leader who trained Kylo Ren, wore a ring that featured obsidian carved from the same cave.[51]

The Corvax Fen was a vaguely hospitable bog that contained irontrees, being one of Mustafar's few such places. Located close to the ruins of Darth Vader's fortress, the fen was guarded by the Alazmec of Winsit, a group of cultists devoted to the Sith Lord.[107] Barren and noxious, the marsh was surrounded by a misty air that smelt of ozone. It contained a shallow lake of brackish water that was covered in an oily film.[39]

Behind the scenes[]

Early conception[]

"It was a whole part of the plot that essentially got cut out. It may be in one of the sequels. […] Ben and Vader have a confrontation, just like they have in Star Wars, and Ben almost kills Vader. As a matter of fact, he falls into a volcanic pit and gets fried and is one destroyed being."
―George Lucas in 1977, the earliest known mention of what would become Mustafar[src]

Concept art of the Emperor's Throne Room situated above a lava lake, by Ralph McQuarrie

By 1977, George Lucas conceptualized the creation of Darth Vader happening after a duel with Ben Kenobi and the father of Luke Skywalker. The father is killed by Vader, who is confronted and nearly killed by Kenobi. Vader falls into a volcanic pit and becomes a destroyed being, necessitating his use of cybernetics.[108] The concept of a lava duel was revisited in the earliest versions of the 1983 film Star Wars: Episode VI Return of the Jedi. In those versions, Luke Skywalker fights Darth Vader over a lava lake in the Emperor's Throne Room, located in the lowest levels of the Imperial capital Had Abbadon. Although this was visualized by veteran Star Wars concept artist Ralph McQuarrie, the concept was not carried over to the final script.[109] The concept of Kenobi dueling Vader, though altered with Skywalker's father now being Vader himself, was realized in Star Wars: Episode III Revenge of the Sith, twenty-eight years after the original film.[4]

Debut[]

Development[]

"Mufasta's been around for a long time. I've always had this set piece: the end between Obi-Wan and Anakin. I knew that's where this movie was going to end up. It's all this volcanic land, with lava shooting up, so it's almost monochromatic in its red-and-blackness. I've had that image with me for a long time."
―George Lucas on Mustafar, known as "Mufasta" at that point in the production of Revenge of the Sith[src]

Released in 2005, Revenge of the Sith marked the first appearance of Mustafar.[4] Brought up as a major location of the film, the volcano world becomes the culmination of the lava designs from the development of the original trilogy. Whilst the planet is named "Mufasta" in earlier concepts for Revenge of the Sith, the finalized spelling was in place by October 25, 2002; George Lucas had decided to dedicate about twenty to thirty minutes screen time to the planet he respelled, and planned to include a major fight as well as a "love scene" there. Despite the new spelling, draftspeople and model-makers working on the film in Australia spelt the planet name as "Mustafa" when labelling an early 3-D rendering of the lava world's Separatist war room.[110] "Mustafa," romanized from the Arabic (أَلْمُصْطَفَى), is an epithet of Muhammad in the Qur'an that means "The Chosen."[111]

Writer-director George Lucas intended the lava planet to symbolize the Biblical hell.[112] Lucas also said that Anakin Skywalker's injuries that were inflicted by Mustafar led to the loss of his power in the Force; Darth Sidious' plan for his new apprentice to become more powerful than himself was derailed by Obi-Wan Kenobi.[113]

Before Lucasfilm artists finished work on the 2002 prequel trilogy film, Star Wars: Episode II Attack of the Clones, George Lucas wanted ideas of what his lava planet for Episode III would look like.[114] At Skywalker Ranch, artists conceptualized Lucas' lava planet as either a technologically-advanced world or a wild, primordial location.[115] Ryan Church made concepts of both using Corel Painter,[114] and one such piece[115] featured Wikipedia:Gothic architectureGothic constructs of skyscraper proportions.[116] When Lucas was shown one of Church's more abstract and fanciful concepts for Mustafar, the director said that he wanted a more grounded design.[117] The concept artists who worked on Mustafar for Episode III include Ryan Church, Aaron McBride, and design supervisor Erik Tiemens.[110] McBride originally designed the Pau'ans seen in the final film as natives of Mustafar, although Lucas decided to use his designs for the residents of Utapau by 2004.[118]

After suggestions of controlled mineral-harvesting environments complete with lava dams and an orbital ring structure that siphoned energy from the lava world, the two extremes ultimately coalesced into what became of Mustafar: a blend of lava-reliant technology and an untamed hellscape.[115][119] The ring world was intended to be a Star Wars take on a Dyson sphere.[120] George Lucas revised his drafts for the film as the concept art for Mufasta developed, and left details of the duel between Vader and Kenobi untouched for guest director Steven Spielberg to form ideas for, based on concept art approved by Lucas during his meetings with the art department.[110]

Production[]

Having heard news that Mount Etna, a volcano on the island of Sicily in Italy, was erupting in late October, 2002, George Lucas asked film producer Rick McCallum to arrange the filming of the ongoing volcanic eruption for Mustafar's imagery. With approval from the Italian government and a local guide, acclaimed documentary filmaker and cinematographer Ron Fricke[110] accompanied McCallum at the site for over a week,[121] capturing the bursting lava on a camera rented from a company in Milan.[110]

Brett Northcutt's animated, cycloramic background matte painting of Mustafar.

Amongst other images, lava fountain elements shot by Fricke were incorporated by[122] digital matte artist Brett Northcutt[123] at the Digital Environments department[121] into an animated background cyclorama used in Revenge of the Sith.[122] A mesh of various assets that also included stills of gravel at the Industrial Light & Magic parking lot and computer generated images, the matte painting comprised of 25,000 pixels and took several months to make, and served as the backdrop for Mustafar in the film. In addition to Northcutt's painting, footage taken from Mount Etna was further cut into the film by George Lucas and editor Roger Barton for the Mustafar sequences.[121]

In the film, while Vader and Kenobi fight on the fallen mining complex arm, the lavafall[4] flows backwards as a result of George Lucas' decision that the camera follows the duelists as they progress in a single direction.[121]

Star Wars: The Clone Wars[]

"Mustafar was also a big deal for me, 'cause I argued with George about that, I said, 'Really, Mustafar?' Because that's where the whole thing with Vader happens […] You find your fan-self clashing with the story that George wants to tell, 'cause we hold everything—'Oh, it's so precious to me, and nobody can know about Mustafar!" […] We take it to such this uber-serious level and it always takes George to, you know, snap you out of it sometimes and say, 'But this a great ending to this trilogy.'"
―Dave Filoni, on his initial reluctance to use Mustafar on the show[src]

An earlier version of the story for the Star Wars: The Clone Wars Season One episode "Liberty on Ryloth" featured Mace Windu rescuing Twi'lek captives from a prison suspended over a volcanic caldera. Although this was cut when production paintings of the setting ended up looking too similar to Mustafar,[124] the location was revived for the Season Four episodes "Slaves of the Republic"[125] and "Escape from Kadavo" as the Kadavo slave processing facility.[126]

The symbolic Well of the Dark Side at the ethereal realm of Mortis.

Mustafar itself made an appearance in the show's second season episode "Children of the Force," serving as the final destination of a three-part arc in the series.[15] Development of the planet for the show was challenging for the Clone Wars team, as the lava and explosion visuals required for the episode called for significant effects work. Supervising director Dave Filoni also noted that Mustafar's inclusion in the show was initially difficult for him as a fan; to him, the planet was too important to Anakin's story in Revenge of the Sith to be included earlier in the timeline. George Lucas, however, convinced him that Mustafar served as the ideal location for the arc's finale, prompting Filoni to rationalize that the world was not likely to be unknown to the galaxy at large, further reasoning that the planet's perceived significance among fans was superseded by the needs of the story.[127]

According to effects supervisor Joel Aron, some of the elements of Mustafar's lava from Revenge of the Sith were repurposed for the Well of the Dark Side on Mortis in the episode "Ghosts of Mortis."[128]

Rogue One[]

"When we established Mustafar as Vader's home for Rogue One, we then needed more interiors and a bigger picture. So it was really fun to dig up those old McQuarrie designs, to figure out how to blend them with our aesthetic, as well as the aesthetic from Revenge of the Sith."
―Doug Chiang on Mustafar's appearance in Rogue One[src]

Mustafar was later featured in the 2016 Star Wars Anthology film, Rogue One: A Star Wars Story. It was the site of Fortress Vader, a stronghold where Darth Vader resided.[17] To prepare for the planet's return to film, art director Doug Chiang and the design team revisited Ralph McQuarrie's old designs for Mustafar and combined them with its depiction in Revenge of the Sith in order to create a unique aesthetic. Fortress Vader was created based off of a few of McQuarrie's designs. Interior concept designs for what eventually became the stronghold were created by Ryan Church, Matt Allsopp, Luke Fisher, Julian Caldow, Thom Tenery, Brett Northcutt, and Erik Tiemens, while the landscape was drawn by Allsopp and Christian Alzmann.[129]

The Rise of Skywalker[]

"The one time we weren't in the studio got cut."
"Yes. One time we were in a battle scene in a forest, with Kylo Ren. Our bits got cut out, so we have to wait for those on the extras."
―Gleeson and Grant speak on their deleted scene[src]

Domhnall Gleeson and Richard E. Grant on The Rise of Skywalker's Mustafar set

The planet was featured in the opening scene of the 2019 sequel trilogy film Star Wars: Episode IX The Rise of Skywalker, in which Kylo Ren leads a First Order attack on Mustafar to obtain a Sith wayfinder. Although the final film features only about a minute of screentime for the world,[94] additional scenes were originally planned. Actors Domhnall Gleeson and Richard E. Grant, who played the First Order leaders Hux and Pryde, respectively, have stated that at one point their characters were meant to accompany Ren to Mustafar. Although the actors did indeed film the scene, it was removed from the final cut of the film. Gleeson and Grant expressed a desire to see the scene released on home media,[130] but the footage was never provided.[94] A version of this scene was later included in Rae Carson's 2020 novelization of the film.[39]

Another deleted scene, featuring Ren's encounter with the Eye of Webbish Bog and a giant on the planet, was filmed near the United Kingdom's Pinewood Studios in a lake at Black Park. According to creature and special make-up effects creative supervisor Neal Scanlan, the scene was cut due to its long length and concerns with conveying information to the audience effectively.[131] This scene also went on to be included in Carson's novelization,[39] as well as in Michael Kogge's junior novelization later that year.[35] The two works present different interpretations of the sequence, however. In Carson's book, Ren wades through the Eye's lake to reach a small island and obtain the wayfinder,[39] whereas Kogge's adaptation depicts the creature pointing Kylo beyond the lake and towards the remains of Vader's fortress.[35] This article assumes neither story has canonical precedence over the other and presents a combined version of these events.

Starfighter Missions[]

In the 2020 mobile video game Star Wars: Starfighter Missions, Mustafar appears as one of the locations over which starfighter battles take place.[132]

The later issue Darth Vader: Dark Lord of the Sith 19 features the Second Sister, who is killed in Star Wars Jedi: Fallen Order. Fallen Order takes place five years after the Great Jedi Purge, which is dated to 19 BBY by Galactic Atlas. Therefore, Fallen Order is also set in 14 BBY. As Dark Lord of the Sith 18 is set between both Tarkin and Dark Lord of the Sith 19, the events of the former issue must take place in 14 BBY, as well. The events of Darth Vader: Dark Lord of the Sith 21 take place shortly after the events of issue 19 and therefore also around 14 BBY.

  62. Star Wars: The Rise of Skywalker: The Visual Dictionary states that Fortress Vader was completed forty-six years before the Starkiller Incident, which Star Wars: Galactic Atlas dates to 34 ABY.

  68. Solo: A Star Wars Story The Official Guide dates the segments of Solo: A Star Wars Story that features Lando Calrissian as the owner of the Millennium Falcon during the Galactic Empire's existence to nine years after the formation of the latter organization, which Star Wars: Galactic Atlas dates to 19 BBY. Therefore, it could be found that the aforementioned segments of Solo took place in 13 BBY. Since Lando's Luck depicts Calrissian in possession of the Falcon during the reign of the Empire, and the novel's events is established to have taken place shortly prior to the events of Solo: A Star Wars Story, thus placing the events of Lando's Luck to or shortly before 13 BBY. Because Star Wars: The Rise of Skywalker: The Visual Dictionary states that Fortress Vader was completed forty-six years before the Starkiller Incident, and Galactic Atlas dates the Incident to 34 ABY, it could be found that the fortress was constructed in 12 BBY, and the events of Lando's Luck must have taken place around that time.

  70. The Del Rey timeline places Thrawn between Solo: A Star Wars Story and A New Dawn. Solo: A Star Wars Story The Official Guide dates the prologue of Solo to six years after the formation of the Galactic Empire, which Star Wars: Galactic Atlas dates to 19 BBY. Therefore, it could be found that Solo took place in 13 BBY. Star Wars Rebels: The Visual Guide dates Kanan Jarrus and Hera Syndulla's first meeting in A New Dawn to six years before Star Wars Rebels, which, according to the Galactic Atlas, begins in 5 BBY. This places A New Dawn in 11 BBY. This means that Thrawn must begin between 13 BBY and 11 BBY. Thus, events from the early chapters of Thrawn, including Mitth'raw'nuruodo's time at the Royal Imperial Academy, must have occurred around 13 and 11 BBY. This includes 12 BBY, which could be found to be the date of construction of Fortress Vader since Star Wars: The Rise of Skywalker: The Visual Dictionary states that the fortress was completed forty-six years before the Starkiller Incident, which Star Wars: Galactic Atlas dates to 34 ABY.

  75. According to Star Wars: Scum and Villainy: Case Files on the Galaxy's Most Notorious, in the year 7973 C.R.C., Ketsu Onyo resigned from Black Sun. It also dates the Battle of Scarif, which Star Wars: Galactic Atlas dates to 0 BBY, to 7977 C.R.C., four years after Onyo's resignation. Therefore, it could be deduced that 7973 C.R.C. is equal to 4 BBY. Since Ketsu Onyo states in Rebels-mini-logo.png Star Wars Rebels – "Blood Sisters" that she currently works for Black Sun, the episode must occur by 4 BBY. As the Siege of Lothal is dated to 4 BBY by Galactic Atlas, and precedes the events of "Blood Sisters," it could be found that the episode took place in 4 BBY. According to StarWars.com Star Wars Rebels Returns...with Princess Leia on StarWars.com (backup link), Rebels-mini-logo.png Star Wars Rebels – "A Princess on Lothal" is "set roughly three years before the events of A New Hope. Since Star Wars: Galactic Atlas dates the events of A New Hope to 0 BBY, Rebels-mini-logo.png Star Wars Rebels – "A Princess on Lothal" must occur in around 3 BBY. Thus, events taking place between "Blood Sisters" and "A Princess on Lothal," including Rebels-mini-logo.png Star Wars Rebels – "The Future of the Force", must occur around 4 BBY and 3 BBY.
