The Star Fortress positioned above Voss was just one of a vast network, perhaps numbering in the hundreds, of Star Fortresses utilized by Emperor Arcann of the Eternal Empire. These fortresses served as observation posts, monitoring conquered worlds during the Eternal Empire conquest for any signs of rebellion. Exarch Andur Melor was in command of this particular Star Fortress, which was defended by numerous Skytroopers and Knights of Zakuul. The Gormak believed that the Star Fortress was the origin of the ailment plaguing their vulnerable population. In 3631 BBY, a Gormak warrior named Rokuss joined forces with the Commander of the Anti-Zakuul Alliance with the goal of dismantling the Star Fortress. Together, they formed a strike force that attacked and demolished the Voss shield bunker that protected the Star Fortress, after which they reconvened at the Alliance base located on Odessen. From that location, Theron Shan and Miot Dengd aided the Commander in their infiltration of the Star Fortress. After battling through multiple levels of the station, the Commander finally reached the Sun Generator chamber and confronted the Exarch directly. During the intense battle, the Sun Generator's safety mechanisms were deactivated, resulting in Exarch Andur Melor's death. The Commander narrowly escaped aboard a shuttle just before the Sun Generator reached critical mass, obliterating the entire Star Fortress and all of the personnel who remained inside.
