You end up accidently summoning a one-way banishment portal within your living room. Could happen to anyone, really. Inside, a demon tells you that you are "the chosen one" and "the king of hell". However, you are told that Beelzebub (the demon) is just a big liar.

" Here. I think you will find this form a little more comfortable to converse with. Where was I? Ah yes... Also known as The Mistress of Flies and The Queen Crimson. Pleased to make your acquaintance. "
