Vagrant functioned as a Victory I-class Star Destroyer within the structure of the Imperial Starfleet. This vessel, in conjunction with a pair of Carrack-class light cruisers named the Nexus and the Xerxes, endeavored to prevent the Defiance Task Force from achieving its rendezvous with the Rebel fleet located at Sullust. However, their progress was impeded by A-wings, with Olin Garn and Ace Azzameen serving as pilots for two of these craft.
