Zariel

The Fallen One
The fiery first layer of the Hells is known as Avernus, and is ruled by the Archduchess Zariel, a fallen angel. She is the example Asmodeus has set for all the other would be crusaders, that the price of aggression against him can be worse than death. Zariel was a nightmare for devil kind, she flew from layer to layer slaying all who she could find, evading the hordes hoping to slay her. The different rulers of the Hell's waited for Asmodeus's wrath to fall upon the intruder, but the Overlord knew better, he knew death awaited her and she wasn't afraid. What she didn't know was the dangers inherent in hunting the pervasive evil of the Hells. Before long she had become that which she hated, now she rules over the devils with the same fury that she had hunting them.

As the Archduchess of the first layer she has many rivals and foes, the former ruler Bel who now must advise her, the goddess of greed Tiamat who shares the first layer and any who wish to enter the lower layers must deal with her. She is the guardian to everything she once fought so hard to destroy, her hate is what makes her dangerous, and Asmodeus will never let her go.
