"I've never seen any other libraries. What are they like? Probably bookcases hanging from the ceilings, and mephits living in the fireplace. Let me tell you about this library. It's for our books, ones from the First World. Other types of books don't like it here and disappear. We have books about everything: joy, triumph, fear... If you want to, you can walk around and read whatever you like. But remember: books about evil and bad things are on the lower shelves. Terrible fear. Vicious joy. Books about good things go on the top shelves!"
