Imperial Security Bureau

The Imperial Security Bureau (ISB) was an enforcement agency of the Galactic Empire that was charged with matters of state security and ensuring the loyalty of citizens to the Empire. One of its members was Agent Kallus, who searched for signs of disloyal activity or insurgency in order to ensure it did not spread into a full rebellion against the Empire. ISB agents wore a distinctive type of helmet with cheek pieces that was designed to both symbolize their status and instill fear in their opponents.
