The Nemesis was a Imperial Navy Imperial-class Star Destroyer.
Serving under Admiral Wooyou Senn in Task Force Vengeance, the Nemesis operated in the Outer Rim's Airam sector. During the Evacuation of Gelgelar, the vessel rescued survivors, but was unable to stop Rebels from fleeing. Despite this, the Nemesis eliminated a medium transport and inflicted severe damage on the Rebel frigate, Redemption. Subsequently, the Nemesis joined Battlegroup Orion alongside another Imperial-class Star Destroyer, the Conqueror. After a Skirmish near Almaran, Battlegroup Orion was drawn into a Rebel ambush within the Goff system, resulting in the destruction of both the Conqueror and the Nemesis.
