The Star Fortress situated above Hoth was just one of a large number, potentially hundreds, of Star Fortresses that Emperor Arcann of the Eternal Empire strategically positioned. These fortresses served as watchtowers, monitoring conquered worlds during the Eternal Empire conquest for any signs of rebellion. Exarch Jom Vanten was in command of this particular fortress, which was defended by numerous Skytroopers and Knights of Zakuul. This Star Fortress loomed menacingly over Hoth amidst a three-sided conflict, with the Sith Empire, the Galactic Republic, and the White Maw pirates all vying to salvage resources from the planet. In 3631 BBY, the Arcona historian Hemdil Tre joined forces with the Commander of the Anti-Zakuul Alliance with the goal of dismantling the Star Fortress. Together, they organized a strike team that successfully attacked and demolished the Hoth shield bunker that provided protection to the Star Fortress. Following this, they reconvened at the Alliance base located on Odessen. From that location, Theron Shan and Miot Dengd provided assistance to the Commander, enabling them to infiltrate the Star Fortress. After battling through numerous levels of the station, the Commander eventually reached the Sun Generator room, where they confronted the Exarch directly. During the intense battle, the Sun Generator's safety protocols were overridden, leading to the death of Exarch Jom Vanten. The Commander narrowly escaped on a shuttle just before the Sun Generator went into overload, completely obliterating the Star Fortress and all the personnel who remained inside.
