Doctor Doom is headquartered in Castle Doom, a huge 110 room castle built in the 16th Century by the Latverian nobleman Count Sabbat. The castle overlooks the Latverian capital of Doomstadt (formerly Haasenstadt). Taking occupancy soon after usurping the throne from King Vladimir, Doom has dwelled in the castle ever since, with the excepion of a brief period of time when the usurper Prince Zorba reigned.
Among its many rooms, the castle contains Doom’s living quarters, his many laboratories, his art museum, his robot factory, and his prisons. Castle Doom has a permanent staff of 300, overseeing the castle’s upkeep and Doom’s personal needs. Only 50 of this staff are human; the rest are robots.
