Quest for the King
Archdevil of Dis and a Calculating Fiend
Dispater is evilly handsome and looks extremely human besides small horns on his head. He is incredibly cautious to the point of violent paranoia. He always has at least nine back-up plans. He is also very polite and calm despite stressful situations. He lives inside an iron tower that makes him near-impossible to kill. He never leaves the tower unless forced.
Dispater was arguably to first Archdevil to step foot on Dis, and has been ruling it ever since. Other then that, no one knows where the heck he came from.
