Book of Admittance

The Book of Admittance is an ancient book bound by peeling-black dragonhide that sits locked in a small tower, and no human hands have touched it since its placement there by the founders. Beside the book is a small silver inkpot with a long quill called the Quill of Acceptance. The quill writes down the birth of every magical child in the book, as well as non-magical children who display magical ability. Few wizards even know of the book’s existence, and fewer still have ever witnessed it in action. This is the only system that has ever existed for admitting children into Hogwarts—if their name is in the book, they are accepted.
