"Do not underestimate the Sith. Though quaint, they will do whatever it takes to survive."

During the fifth year of the renewed warfare between the Galactic Republic and the reconstituted Sith Empire, the Eternal Empire made an attack on the planet Korriban. It was part of a series of preliminary raids by the Empire, which up to that point had been concealed to the rest of the galaxy, as a test of the strength of the border worlds of the Republic and the Sith.

Korriban was a prime target for the Eternal Empire, due to the presence of the Sith Academy for the training of Acolytes. The twin princes Arcann and Thexan led the assault of the force-sensitive Knights of Zakuul, facing fierce resistance. Arcann was critically injured during the battle, suffering severe burns and the loss of an arm and an eye. However, the following day he was on his feet again and executed the Sith commander Darth Atroxa. Despite the efforts of the Sith, the Knights of Zakuul breached the Sith Academy during the fighting.

The attack was a tremendous defeat for the Sith, while the Eternal Empire only suffered moderate casualties. Following the battle, the forces of the Eternal Empire withdrew, eventually heading back to their throne-world of Zakuul. Shortly afterwards, the Republic and the Sith Empire joined together to find the source of these unknown aggressors.


"Look around you. Zakuul is poised to become the greatest civilization in the history of the galaxy. I have forged this empire to surmount all of my previous works. To span eternity."

Located in the Esstran sector of the Outer Rim Territories,[10] Korriban was the homeworld of the Sith species[11] as well as the Sith Order,[9] though the Great Hyperspace War against the Galactic Republic saw the ruin of the Sith Empire.[11] Millennia later, Vitiate, Emperor of the reconstituted Sith Empire, grew weary of the restraints placed upon him by the Sith and his Empire.[12] Freeing himself, he split his consciousness into a new body, a man named Valkorion.[13] He then set to work forging a new empire from the swamps of the planet Zakuul, which became the Eternal Empire.[14] The new realm became immensely powerful, all the while remaining concealed from the rest of the galaxy in Wild Space.[2]

Centuries later, the Sith Empire returned to the known galaxy, initiating the Great Galactic War against the unsuspecting Republic. Early in the war, the Sith stormed Korriban, overwhelming the few Republic defenders.[15] The abandoned Sith Academy, previously used three centuries earlier during the Jedi Civil War, once again saw use, turning out only the most powerful Acolytes.[9]

Arcann and Thexan - Conquest

Arcann and Thexan lead the Knights of Zakuul earlier in the raids.

Although the Treaty of Coruscant was signed decades later between the two opposing sides, the resulting tension between the Empire and Republic eventually overflowed, spilling into yet another war.[9] Around 3637 BBY, the fifth year of the conflict,[5] Valkorion's twin sons, Princes Arcann and Thexan, proposed a plan to test the capabilities of the Republic and Empire in combat. Valkorion agreed, granting Thexan control of the Eternal Fleet[4]—an armada operated by sentient droids[16] though he ordered that Arcann remain on Zakuul. However, Arcann disobeyed his father's wishes and led the assault alongside his brother regardless.[4] They fought on many worlds, before finally striking at Korriban.[3]

The attackEdit

"Acceptable casualties, on our side. Darth Atroxa remains a threat, but I'm confident she will be neutralized. With her downfall, victory will be ours."

The forces of the Eternal Empire, composed of starfighters, shuttles, at least two battleships and one warship descended on Korriban, facing fierce resistance from the Sith's own naval forces. The latter was comprised of[3] Mark VI Supremacy-class starfighters[3][9] and Fury-class Imperial interceptors.[3][8] Led by Arcann and Thexan,[7] the Force-sensitive[17] Knights of Zakuul and several droids[7] advanced on the Sith Academy[18] on foot.[3]

Knights defend Arcann

A handful of Knights defend Arcann while he is tended to.

They clashed with the Sith under the command of Darth Atroxa[7] in the Valley of the Dark Lords, whose forces were composed of Sith Warriors[3] as well as Acolytes and Overseers from the Academy.[6] During the battle, Arcann was grievously wounded. As several Knights stood guard,[3] medics operated upon him. The prince was later taken away from the battle to an encampment, where he thrashed in pain for hours before finally succumbing to sleep. There, Arcann was further performed upon; by the end of the ordeal, he had been fitted with a replacement cybernetic arm and eye—the latter as a part of a durasteel mask made to protect the prince's burnt face and to intimidate his foes.[7]

While Arcann was incapacitated, Thexan updated Valkorion on the status of the battle via holocom. The emperor did not express concern over his son's injuries, remarking that Arcann had "paid the price for defiance" in leaving Zakuul. The following day,[7] Arcann was on his feet again and led a renewed assault during an intense sandstorm. Darth Atroxa, the Sith commander, met her end by the prince's lightsaber after he used his cybernetic arm to twist her wrist and disarm her.[3]

Darth Hexid was among those Sith who joined in the defense, carving her path through the invaders until she was knocked out by an explosion.[19] Despite Sith resistance, the Eternal Empire stormed the Sith Academy,[18] where Sith Acolyte Veeroa Denz decapitated her Overseer, using the confusion to escape Korriban and the Sith.[6]


"When I woke, I was surrounded by death and ruin. The Eternal Empire had conquered the Sith."
―Darth Hexid[src]
Departing Korriban

Arcann and Thexan depart Korriban via shuttle, leaving the Valley of the Dark Lords in ruins.

The attack was a crushing defeat for the Sith. Not only had they suffered heavy casualties, but considerable damage had been done to[3] a prominent academy for the training of prospective Sith.[20] The Eternal Empire also sustained sizable losses during the battle, though not as extensive as those of the Sith.[7]

As a result of the attack, many Acolytes fled and settled down to live their lives without interference from the Sith or the Eternal Empire, such as Veeroa Denz on Nar Shaddaa,[6] while Darth Hexid despised the weakness of the Sith who bowed down to the Eternal Empire and went to wage her own personal vendetta against Zakuul.[19] When the raids were concluded, the forces of the Eternal Empire returned to Zakuul. A joint Republic-Sith taskforce led by Darth Marr was dispatched to locate the source of these unknown assailants. During the ensuing skirmish with the Eternal Fleet, forces of the Sith Empire identified the starships of the Fleet as belonging to the same faction that had earlier attacked Korriban.[2]

Behind the scenesEdit

Attack on Korriban concept art

Arcann injured on the battlefield

The attack on Korriban made its first appearance in the cinematic trailer Sacrifice, released on June 15, 2015. The trailer promoted the then-upcoming expansion for the massively multiplayer online roleplaying game Star Wars: The Old Republic, titled Knights of the Fallen Empire. The attack served to establish how Arcann sustained his injuries and received his cybernetic replacements, which led to his change of personality to a darker tone.[3]


Notes and referencesEdit

  1. Per Chapter I: The Hunt of Knights of the Fallen Empire, Vitiate's disappearance coincided with the Eternal Empire's raids, which the attack on Korriban was part of. Since Vitiate's disappearance is established in the Chapter as having occurred following the Invasion of Ziost, the attack on Korriban may be concluded as having taken place after the Invasion.

  5. 5.0 5.1 According to the novel The Old Republic: Annihilation, the Treaty of Coruscant collapsed in 3642 BBY, and Star Wars: The Old Republic: Knights of the Fallen Empire states that Choza Raabat disappeared two years before that, or 3644 BBY. The game also establishes that Raabat's disappearance occurred twelve years before the events of Fallen Empire, so Chapters II-VII of Fallen Empire must take place in 3632 BBY, and Chapter I—which takes place five years prior to the rest of the expansion—in 3637 BBY. Chapter IX and the post-chapter content span a number of months, between the years 3632 and 3631 BBY. According to Chapter I, Vitiate's disappearance, which preceded the events of the Chapter, occurred simultaneously with the Eternal Empire's raids, which included the attack on Korriban. As Chapter I may be dated to 3637 BBY, the attack on Korriban may be dated to approximately the same year, having preceded it.
