The SIS offices during the Cold War Stretching a kilometer wide, the Heorem Complex, also known as SIS Headquarters during the era of the Old Republic, was a cluster of structures situated within the Senate District of Coruscant. It shared a boundary with Quadrant H-46 and housed the Heorem Skytunnel, a conduit linking these two areas.
Throughout the Cold War, the Complex functioned as the central base of operations for the Republic Strategic Information Service, distinct from the SIS operations center, and included the offices belonging to the Director of SIS.
