The Star Fortress that hovered above Belsavis was just one of a vast network, potentially numbering in the hundreds, of Star Fortresses deployed by Emperor Arcann of the Eternal Empire. These fortresses were strategically positioned to monitor conquered worlds, such as Belsavis, for any signs of rebellion following the Eternal Empire conquest. Under the command of Exarch Forta Gair, this particular Star Fortress was heavily defended by Skytroopers and Knights of Zakuul. Notably, the Star Fortress was deploying shuttles to the depths of the Belsavis prison, releasing inmates and thereby instigating widespread chaos. In 3631 BBY, the Whiphid recruiter K'krohl joined forces with the Commander of the Anti-Zakuul Alliance with the aim of dismantling the Star Fortress. Working together, they formed a strike team that successfully attacked and demolished the Belsavis shield bunker that provided protection to the Star Fortress, before subsequently regrouping at the Alliance base located on Odessen. From that location, Theron Shan and Miot Dengd aided the Commander in a covert operation to infiltrate the Star Fortress. After battling through numerous levels within the station, the Commander finally reached the Sun Generator chamber and confronted the Exarch directly. During the intense combat that ensued, the Sun Generator's safety mechanisms were overridden, resulting in the death of Exarch Forta Gair. The Commander narrowly escaped aboard a shuttle just before the Sun Generator reached critical overload, completely obliterating the Star Fortress and all the personnel remaining on board.
