The Asteroid of Doom is Sludge Vohaul's fortress, orbiting Labion. It was inhabited during the door-to-door salesmen plot in and destroyed by Roger Wilco during the denouement of that matter. Employs robots, traps, and non-sentient beings for security; otherwise, only a minimal staff is on hand to assist Vohaul in his developments. Sariens are said to have served on board as well.
