At Hogwarts, Albus Dumbledore introduces ex-Auror Alastor "Mad-Eye" Moody as the new Defence Against the Dark Arts teacher. He also announces that the school will host the Triwizard Tournament, in which three magical schools compete across three challenges. Only wizards aged seventeen and above may compete. The Goblet of Fire selects "champions" to take part in the competition: Cedric Diggory of Hufflepuff representing Hogwarts, Viktor Krum representing the Durmstrang Institute from Eastern Europe, and Fleur Delacour representing the Beauxbatons Academy of Magic from France. The Goblet unexpectedly selects Harry as a fourth champion. Dumbledore is unable to pull the underage Harry out of the tournament, as Ministry official Barty Crouch Sr. insists the champions are bound by a contract after being selected.
