The Rising Arch-Devil
A humongous pit fiend who dwarfs even regular pit fiends. He is arrogant and egotistical, but always speaks calmly. He can be very paranoid and distrustful.
As a servant of Dispater he trusted no one, not even his own Arch-devil. He kept his unit and subordinates in small amounts and only kept as many as he knew he could defeat on his own. He came to the mortal realm to conquer his own territory and establish a new hell before any other devils try to do so themselves.
