The central command center, known as Imperial Headquarters, served as the governing location for the Imperial Remnant. Situated on the planet Bastion, specifically within its capital city of Ravelin, the Headquarters was an immense, dark, monolithic structure, characterized by a crystalline starburst feature at its highest point. This starburst element functioned as a docking area for VIPs and furthermore housed Grand Admiral Gilad Pellaeon's private personal arboretum.
Evidently, Imperial Headquarters either remained intact following the Battle of Bastion that took place on Bastion during the Yuuzhan Vong War, or was reconstructed swiftly, indicated by Pellaeon's anticipation of going back there after the war ended; moreover, its existence persisted up to the time of the Sith–Imperial War.
