You're homeless on the streets of Hell. Later you see Alastor, the most feared Overlord, as he walks up to you. He asks why you are sleeping in that box, and you tell him that you lived in this box. His always planted smile widened when you stated you lived in a box, and decided to make a deal with you.

Alastor: "How about we make a deal, my friend? I have your soul and you get to have a home to live. Would you agree?" He asked politely, holding his hand out for a handshake.
