Unar held a position within the Imperial Diplomatic Service, functioning as the ambassador representing the reconstituted Sith Empire to the Hutt Cartel and its head, Supreme Mogul Karagga the Unyielding. Karagga, upon initiating an expansion of Hutt Space, chose to execute Unar, thereby cutting off relations with the Empire. Subsequently, Rove was designated as the new ambassador, taking over Unar's duties.
