Archdevil

s are the rulers of the Nine Hells. They each control one of the nine hells and are the most powerful and highest-ranking devils. Unlike the demon lords of the Abyss, the Lords of the Nine Hells are arranged in a strict hierarchy. The lord of the first layer has the lowest rank of the nine archdevils, while the lord of the ninth and deepest layer, Nessus, has the highest rank. While the demons of the Abyss answered only to their own basic instincts, every single devil, at least in theory, answered to the Lord of the Ninth, Asmodeus. Every archdevil is a unique being with an appearance that reflects its particular evil nature.

One of the Arms of the Betrayers was created by Asmodeus: the Mace of the Black Crown. One of the few proposed ways to destroy one of the Arms of the Betrayers is to bathe it in the ichor of an archdevil.
