The Office of Internal Review of the ISB existed as a division within the Imperial Security Bureau of the Galactic Empire, situated on Coruscant. It served as the location where Imperial staff facing accusations were escorted. Individuals such as Admiral Corleque, Agent Fabarian, Governor Tauntaza, and Council Member Xanto were brought before this office, where Sub-Administrator Sly Moore listened to their complaints. Unbeknownst to others, Moore was covertly organizing the Schism Imperial, a collection of Imperial figures who were unhappy with Emperor Palpatine. She executed Xanto, who was the sole loyalist to the Emperor among them, and subsequently enlisted the remaining three into her rebellious organization.
