"I think I've been shown how the presence--how the Unnamed--works. It looks for a door, a way into your heart. Sadness. Grief. Jealousy. Melancholy. It finds an opening and enters."
"Demons afflict the weak."
"Or the ones who ask for help without caring who's ready to give it."
"Then what?"
"It breaks down the wall between what you can imagine doing and what you would never do."
Andrew Pyper * The Demonologist
