Internal Affairs served as a division within the Galactic Empire's Imperial Security Bureau, tasked with the crucial mission of identifying and eliminating disloyal individuals within the Empire's vast organization. To ensure vigilance, each Star Destroyer had an Internal Affairs loyalty officer assigned to it, dedicated to uncovering any indications of rebellious activity within the ship's personnel.
Agent Kallus held positions not only in Internal Affairs but also in the Investigations and Enforcement divisions.
