"We're the Imperial Security Bureau. What we say is principle; what we decide is regulation; what we do is law." "And whoever you order shot is dead?" "So you do understand."
― Drelfin and Daric LaRone
The Imperial Security Bureau (ISB), the public branch known as Imperial Security Services or simply Imperial Security, was a law enforcement and internal intelligence organization of the Galactic Empire under Galactic Emperor Palpatine. Based in the massive ISB Central Office on Imperial Center, it was separate from, larger than, and often rival to Imperial Intelligence.
