An Imperial-class Star Destroyer was under the command of Admiral Wilhuff Tarkin in the initial months of the Galactic Empire's existence. This Star Destroyer participated in the Empire's campaign aimed at Separatist holdouts situated in the Western Reaches; consequently, it was repaired at a shipyard orbiting Kartoosh due to battle damage. It was during this time that Lieutenant Commander Orson Callan Krennic conferred with Tarkin onboard the starship, where they deliberated strategies concerning a highly classified top-secret project.
