The COMPNOR Arcology was a labyrinthine building on Imperial Center, the capital world of the Galactic Empire. It was located in the planet's Federal District, on Level 5127. It housed several Imperial organizations, including the Commission for the Preservation of the New Order, the Imperial Security Bureau, and the Ubiqtorate. Five years before the Battle of Yavin, the Minister of Information of the Galactic Empire, Pollux Hax, maintained an office there.
