At Hogwarts, Professor Dumbledore announces that Alastor "Mad - Eye '' Moody will be the Defence Against the Dark Arts teacher for the year, and also that Hogwarts will host the Triwizard Tournament, with a prize of one thousand gold Galleons. However, only those over 17 -- the age of majority in the wizarding world -- will be allowed to enter. It is the first time in 202 years that the Triwizard Tournament will be held. Students from Beauxbatons Academy and the Durmstrang Institute, other wizarding academies, will travel to Hogwarts, where they will stay for the year, in hopes of competing. At Halloween, the Goblet of Fire picks Fleur Delacour from Beauxbatons Academy; Viktor Krum (who is also the Seeker on Bulgaria 's Quidditch team) from Durmstrang Institute; and Cedric Diggory from Hogwarts to compete in the tournament. However, it additionally gives a fourth name -- Harry Potter -- leading to suspicion and indignation from everyone and magically binding Harry to compete. Ron is jealous that Harry is once again in the limelight and refuses to speak to Harry.
