Dispater is a great archdevil and the powerful lord of Dis, the second plane of Baator. He wears red robes and looks humanoid, except for his goat hooves, small horns, and spiked tail. He carries his legendary Rod of Dispater and rules from his fortified Iron Tower in the iron city of Dis, named after the whole plane itself. He is an amazing strategist and often fights defensively. His Iron Tower of Dis provides amazing protection. Dispater is said to have skin almost as hard, or even as hard, as iron. He is worshiped by some mind flayers.
