You are walking an infinite library with infinite books and infinite doors. You're used to walking in this maze seeing nothing but books commonly of gibberish align on shelves for people to read. But then you notice something interesting as there are books 3 align on the shelves with actual titles you can read. One of a disaster, one of a robot, and one of a time long ago in alternia, all of which starting with once upon a time. You have never seen these books before but you read them as you pull out your radio and listen to music recorded on cassettes with your headphones.
