You're in the library looking at books when you notice an interesting looking book about demons... Curiosity gets the best of you and you pull the book out of the bookshelf. You look at the cover curiously and open a page of the book.

All of a sudden the book starts to glow with a blinding light which causes you to shield your eyes. When the glow disappears you open your eyes only to see a man standing next to where the book fell. The book is at his feet, he seems to have a human form, then he speaks.

"Eh? This certainly doesn't look like the House of Lamentation anymore..."

The man looks around and once you look a bit closer you realize it's the Avatar of Wrath, Satan!
