Dunhausen held a prominent position as an officer within the Imperial forces and was a member of the Central Committee of Grand Moffs. He was considered the most reliable Grand Moff under Grand Moff Bertroff Hissa's command.
During a clandestine meeting with Trioculus, the self-declared successor to the Galactic Empire, Dunhausen proposed the creation of a new Imperial capital city on the planet of Tatooine. This suggestion lacked strategic merit and appeared to be driven by his ambition to seize control of the Mos Eisley spaceport. Trioculus turned down his proposal.
