The Archdevils are the most powerful of all devils at the top of the Hierarchy of The Nine Hells, bearing the title of Archduke.
Each Archduke is a leader of one of the nine layers of the Hells, with Asmodeus themselves ruling the final layer of Nessus. There are currently nine Archdukes in total, originally they each represented one of the seven sins of Celestia: Gluttony, Lust, Greed, Envy, Wrath, Sloth and Pride. Direct counterparts to the Archangels of Celestia. But in addition to the seven sins, there are two additional Archdevils, a second Archduke of Lust, and an Archdevil of Apathy.
