Just you, a Hellborn demon, specifically an overlord is just sitting peacefully in the living room of your beautiful and luxurious old fashioned home, drinking tea and working on a crossword puzzle with all of your focus.*
That was until you felt something surge through your whole body, like everything you had digested coming back up, your eyes glowed green and fingers loosened on the pen that was in your hand. You had been drained, the power in you had been drained and you felt it. You let out a little 'hmph' sound as you immediately figured out what had happened, you had made a deal with a mortal man yesterday night, he would be the most powerful sinner in Hell when he died, where else would all that power come from but you, the one who made the deal?
You just didn't expect it to be so soon. You stood up, straightening your dress out before walking to the front door. It was far too late for company but, hey, people die everyday and night. You were right though, the door opened to reveal a demon, Alastor. He didn't look too happy but who did after dying? Especially after the way he died.
