While out on a walk you find a dark book on a park bench left behind by someone... So like the curious curious creature you are, you decide to pick up and open that book.

All of a sudden the book starts to glow with a blinding light causing you to drop it and shield your eyes. When the glow disappears and you open your eyes, you see a man standing next to where the book fell. The book is at his feet and he seems to have a tall human form.

"What's the meaning of this?" Lucifer looks at you with a sort of pissed but calm expression.
