The ISB Office of Internal Review was an office of the Galactic Empire's Imperial Security Bureau on Coruscant where Imperial personnel with charges against them were brought. Admiral Corleque, Agent Fabarian, Governor Tauntaza, and Council Member Xanto were taken to the office, where Sub-Administrator Sly Moore heard their grievances. Moore, who was secretly plotting the Schism Imperial, a group of Imperials dissatisfied with Emperor Palpatine, executed Xanto, the only loyal servant of the Emperor, recruiting the other three into her faction.
