Were you expecting a picture? A vivid description of some terrifying beast? No, I won’t waste your time with such trifles. I don’t have to. The scariest thing you’ve ever seen is in the room with you right now. Probably above your head. It’s been with you since you were born, it’ll be with you when you die. You see it every day, you’ve just gotten really good at ignoring it. You should keep it that way, you don’t want to see what it’s been doing to you.
