Imperial Headquarters was the seat of power for the Imperial Remnant. Located on the planet Bastion in the capital city Ravelin, it was a towering black monolith, with a crystalline starburst at the pinnacle. This starburst could be used as a docking bay for important visitors, and also contained Grand Admiral Gilad Pellaeon's personal arboretum.
Imperial Headquarters apparently survived the Battle of Bastion on Bastion during the Yuuzhan Vong War or was quickly rebuilt, as Pellaeon looked forward to returning there following the end of the conflict, and it still existed as of the Sith–Imperial War.
