The Shieldmaiden, a vessel belonging to the Imperial-class Star Destroyer line, served within the ranks of the Imperial Navy. Captain Khione held command of this warship in the time leading up to the Battle of Endor. In the aftermath of several daring events, a Rebel strike team brought about Khione's demise and inflicted substantial damage upon the Shieldmaiden. This team, headed by Alderaanian princess Leia Organa, then absconded with the shuttle named Tydirium.
