- "It's funny that your land is being swallowed. From the sky, we noted several other landmasses that appeared far more habitable. Grasslands and forests, perhaps, even a few large compounds that suggest some sort of civilization. But no one answered our distress call. What do you make of that?"
- ―Brendol Hux talking with Phasma about Parnassos from orbit
Parnassos was a desolate planet located in the galaxy that was the homeworld of Phasma. Formerly lush and green, Parnassos had been colonized by the Con Star Mining Corporation. Following a nuclear disaster, Con Star abandoned Parnassos and abandoned the colonists, who were forced to eke out a perilous existence on the environmentally-ruined world.
Whilst on a mission to recruit the greatest warriors in the galaxy, the First Order General Brendol Hux was stranded on Parnassos after his starship was shot down by an automated defense system. Hux encountered the Scyre warrior Phasma, who helped him find his ship in return for joining the First Order.
Parnassos was a planet that was once a lush and enjoyable world, at least as portrayed by Con Star Mining Corporation in their advertising and training programs. It had mountains, greenery and crystal blue oceans. The oceans were so clear that the sandy bottoms were visible. There were also valleys that were rich in greenery and nature's bounty.
However, following a nuclear disaster at Calliope Station, the planet underwent a dramatic change in environment. The oceans became dark, cold, forbidding and teeming with hungry beasts. Much of the greenery was turned into a large desert with purple sand. Most of the food animals were killed. Due to the nuclear disaster, the planet's oceans continued to rise, acid rain was also a common occurrence, and many of the food animals were killed off.
Parnassos was home to several continents. The landmass which Phasma inhabited was largely covered in mountains and deserts. The Scyre territory, from which Phasma came, had black spires of rock along with caves and cliffs including the Nautilus, a cave which served as the home of the Scyre clan. The Scrye territory bordered a plateau that the Claw territory was located on. The Scrye and Claw territories were located high above the continent's surface.
Phasma's continent was the site of Terpsichore Station, Con Star's largest mining station on the planet. It was situated in a formerly lush valley that was a short tram ride away from the Siren Sea, which used to be a former tourist destination. This continent was also home to Arratu Station, a former Con Star outpost that had developed into a city. Farther away from Arratu Station lay the dead lands, a radioactive wasteland surrounding a former nuclear plant which had malfunction, causing a cataclysmic nuclear reaction. There was also another station called Calliope Station, which had a medbay.
The planet also had several other landmasses which had grasslands, forests, and a few settlements. One such landmass that lay across the ocean was home to Cleo Station, an abandoned Con Star factory used to produce mining equipment. While that settlement was more lush than the Scrye territory, a famine killed most of the population. 
Flora and faunaEdit
Parnassos was home to a toxic species of lichen which could be used to coat blades. Some notable animals that were indigenous to Parnassos included venomous gold beetles, sea urchins, snails, skinwolves, squeeps and large lizards that were used to draw sleds. The planet's oceans were also home to hungry teeming creatures including large creatures with meter-long teeth.
Parnassos was settled during the Republic Era by Con Star Mining Corporation, which wanted to exploit the planet for its metals and minerals. Con Star also established several settlements throughout the planet with laboratories, factories, mines, and houses for the colonists including Terpsichore, Arratu, Calliope, and Cleo Stations for various purposes. Con Star also built a powerful automated orbital defense system around the planet.
Approximately a hundred years before the Cold war, a poorly-maintained reactor at an unidentified Con Star station malfunctioned, causing a nuclear reaction that devastated the planet's environment. The building housing the reactor as well as the surrounding buildings were destroyed while the surrounding land was reduced to a radioactive wasteland called the "dead lands." Much of the surrounding continent was reduced to a barren desert.
Overnight, Con Star abandoned Parnassos, erasing it from official files. The few remaining records listed the planet as uninhabited. Latter observers such as First Order General Brendol Hux speculated the disaster was either the result of Con Star's malfeasance or sabotage by a rival company.
Surviving the apocalypseEdit
The planet's abandoned population were reduced to a primitive existence. Some like the Scyre and Claw clans became hunter-gatherer societies consisting of small bands that fought for territory and resources. Since the devastation killed off many of the food animals and plants, some clans like the Scyre used machines called detraxors to extract nutrients and minerals from fallen sentient beings and animals to create a nutritious paste.
In the absence of their sentient supervisors, the droids at Terpsichore Station became self-aware and yearned for the return of their "creators." Meanwhile, Arratu Station became a lush, green city inhabited by a wealthy elite and an impoverished commoner class. The city's rulers, known as Arratu staged gladiatorial fights in order to keep the masses entertained. Across the ocean, the inhabitants of Cleo Station, a former factory settlement, survived due to bountiful fields of grain.
The woman who would become Phasma and her family inhabited a cave called the Nautilus. Despising what she termed as her parents' "weak and indecisive" leadership, Phasma conspired with the Scyre clan to kill her own family with the exception of her older brother Keldo, whom she wounded in the leg. Phasma and Keldo subsequently joined the Scyre.
After the Scyre leader Egil was murdered by the young upstart Porr, Phasma defeated him in combat while Keldo hobbled him. Keldo and Phasma then became the co-leaders of the Scyre, the former serving as political leader and Phasma as military leader. Due to the high infant mortality rate, the Scyres only produced one child, a girl named Frey. Following a failed Claw attempt to kidnap Frey, Keldo negotiated a truce with the Claws' leader Balder, a Dug. However, his truce earned him the enmity of the militaristic Phasma.
General Hux's expeditionEdit
During the Cold War, General Hux traveled to Parnassos while on a mission to recruit warriors for the First Order, a remnant of the Old Empire seeking to overthrow the New Republic. While approaching the planet, Hux's ship was shot down by Parnassos' orbital defense system. The ship crashlanded in the "dead lands" while Hux and three stormtroopers PT-2445 ("Pete"), LE-2003 ("Elli"), and HF-0518 ("Huff") landed in an escape pod near the Claw territory.
Hux and his fellow survivors were captured by Balder, the Dug leader of the Claws. Hux related his predicament to the Claws and offered them a life of wealth and comfort if they joined the First Order. Before the Claws could consider Hux's offer, Phasma assassinated Baldor and convinced Hux and his troopers to accept her help. Following a fight with the Claws, the Scyre and Hux's party managed to escape back to the Nautilus.
Unable to convince Keldo to support the expedition, Phasma and her most loyal warriors Siv, Torben, Gosta, and Carr left the Nautilus with Hux and his men. They also stole the Scyre's supplies including their two detraxors. Traveling through Parnassos' inhospitable deserts and a mountain, Phasma and Hux's party braved venomous beetles which claimed the life of Carr, marauders riding large lizards, and a pack of mutated skinwolves.
After Hux was bitten by a skinwolf, the group sought shelter at Terpsichore Station, which was inhabited by self-aware droids. While Hux sought treatment, Phasma and the others were force to work as indentured miners to pay off Hux's medical bills. Working together, the group managed to breach the control room and disable the droids. The group then departed on a ground assault vehicle and several speeder bikes.
While traveling towards Arratu Station, Hux and Phasma's party were ambushed and captured by the locals. They were brought to Arratu Station where they were forced to fight in the arena. Working with Torben and Siv, Phasma managed to kill the Arratu champion Wranderous and the ruling Arratu, leaving the city in a state of anarchy. The group then fled Arratu, continuing their quest to Hux's ship.
Hux and Phasma's group then traveled to the "dead lands" but were pursued by Keldo and the combined Scyre and Claw forces. Following a fierce battle outside Hux's ship, Phasma managed to kill Keldo. Despite the destruction of the enemy forces, Hux's stormtroopers and most of Phasma's followers with the exception of Siv were killed. Meanwhile, Hux managed to contact the First Order for an evacuation.
General Hux's son Armitage Hux soon arrived with a Resurgent-class Star Destroyer and an Atmospheric Assault Lander. Phasma along with the orphaned Frey, who had accompanied Keldo's party, boarded the shuttle with Hux. However, Phasma barred Siv from joining them for disobeying her order to kill Wranderous. Before departing Parnassos, General Hux orbitally bombarded the Nautilus and Arratu Station as a demonstration of the First Order's power.
A year after joining the First Order, Phasma returned to the site of Hux's crashed ship. She removed the ship's chromium plating and then flew on her TIE/sf space superiority fighter to Cleo Station across the ocean. There, she discovered that the population had starved to death due to a famine afflicting their grain crops. Phasma used the station's armory to forge the chromium plates into her unique armor.
Despite being abandoned to die in the "dead lands", Siv managed to seek shelter at Calliope Station where she was treated for radiation sickness. After recovering, Siv later gave birth to a daughter named Torbi. Ten years later, Siv encountered the Resistance spy and operative Vi Moradi, to whom she recounted Phasma's biography prior to joining the First Order. After escaping the First Order Star Destroyer Absolution, Vi traveled with the wounded stormtrooper captain Cardinal to Parnassos to honor her promise to bring Siv and Torbi offworld.
Behind the scenesEdit
Parnassos first appeared as a major plot setting in Delilah S. Dawson's 2017 novel Phasma, which chronicles the origins of the eponymous character. Phasma was produced as part of the multimedia series Journey to Star Wars: The Last Jedi prior to the release of Star Wars: Episode VIII The Last Jedi on December 15, 2017.
When asked about her description of Parnassos during an interview with StarWars.com, Dawson described Parnassos as the Earth after a nuclear disaster, where the rain is poison, the food-animals are dead, and the land is barren and rocky, with an angry ocean esque-Mad Max: Fury Road, a 2015 film which inspired Dawson during the writing of Phasma.
