Harry Potter and the Goblet of Fire
At Hogwarts, Professor Dumbledore announces that Alastor "Mad-Eye" Moody will be the Defence Against the Dark Arts teacher for the year. Dumbledore also announces that Hogwarts will host a revival of the Triwizard Tournament, in which a champion of Hogwarts will compete against champions from two other European wizarding schools: Beauxbatons Academy, and Durmstrang Institute. The champions are chosen by the Goblet of Fire from names dropped into it. Because Harry is under 17 (the age of majority in the wizarding world), he is disallowed from entering.
