Triwizard Maze

On June 24, the Third Task was to navigate a maze grown on the Hogwarts Quidditch pitch. The maze was populated by various obstacles and dangers that each Champion had to overcome. Crouch Jr, as Professor Moody, was entrusted with placing the Triwizard Cup at the centre of the maze. While doing this, he enchanted the Cup to be a Portkey that would be activated by touch.

Cedric and Harry, tying for first place after two tasks, were to enter the maze first, followed by Viktor, and then Fleur. The first Champion to successfully navigate the maze and reach the Cup would be declared the winner.During the task, Cedric encountered a Blast-Ended Skrewt, which he barely escaped from. Harry had to deal with a Boggart in the form of a Dementor, and overcame an odd golden mist which turned things upside-down. Crouch Jr, however, was leaving nothing to chance. Using Moody's magical eye, he watched events unfold in the maze, keeping the more dangerous obstacles out of Harry's path. He also Stunned Fleur, and placed the Imperius Curse on Viktor. He used Viktor to attack Cedric with the Cruciatus Curse in order to clear Harry's path to the Cup.

Harry encountered the Blast-Ended Skrewt that had attacked Cedric, then heard Cedric being tortured, and rescued him by Stunning Viktor. Cedric and Harry parted company, and Harry had to answer a riddle from a Sphinx to continue on into the maze.

Cedric and Harry joined forces to defeat an Acromantula, before they both arrived at the Cup together. After an argument over who deserved to win more, they decided to take the Cup together, since it would still be a Hogwarts victory. Touching the Cup at the same moment, they activated it as a Portkey, and were transported out of the maze. This task eventually lead to the Return of the Dark Lord and the Duel in Little Hangelton, and Cedric Diggory's death.
