Jaius Yorub was a male Sullustan who served in the Galactic Alliance Defense Force. A naval officer, he was captain of the MC140 Scythe-class main battle cruiser Indomitable during the Sith–Imperial War of 127–130 ABY. The Indomitable served as the flagship of the Galactic Alliance Core Fleet, under the command of Admiral Gar Stazi. During the final engagement of the Sith–Imperial War—the Battle of Caamas in 130 ABY—Stazi took elements of the Core Fleet and began a resistance against the combined forces of the Fel Empire and the One Sith rather than surrender. Yorub accompanied the admiral into self-imposed exile.
