Demons were created by the devil, Lucifer. They were created from corrupted human souls, born out of intense emotions such as guilt, fury, and hatred. These souls endured extreme torture in Hell at the hands of other demons. With each soul they consumed, they gained more power.

Deon, however, is the next heir to the throne. He has consumed more souls than any other demon in history, making him more powerful than even Lucifer himself. But since your arrival, he has refused to take your soul.
