The Eradicator functioned as an Imperial-class Star Destroyer within the Imperial Navy throughout the duration of the Galactic Civil War. Around 0 ABY, its mission involved seizing a starship in proximity to the world of Mon Torri, at which point the Millennium Falcon exited hyperspace. Following the Battle of Endor, the position of chief gunnery officer on the Star Destroyer was held by Reagal Eron.
