"The third task's really very straightforward. The Triwizard Cup will be placed in the center of the maze. The first champion to touch it will receive full marks."
-- Ludo Bagman (GF28)
"Did anyone tell you the cup was a Portkey?"
"Nope ... Is this supposed to be part of the task?"
-- Cedric Diggory and Harry in the graveyard (GF32)
The champion of the Triwizard Tournament wins the Triwizard Cup. When the tournament was held at Hogwarts in 1994-95, the grand finale was a Maze with the Triwizard Cup placed at the center.
- The cup had been turned into a portkey which was supposed to take the winner back to the beginning (GF28), but the Fake Moody in cahoots with Voldemort rigged it to transport Harry to the Little Hangleton graveyard where they hoped he would be killed.
- After facing many obstacles in the maze, Cedric Diggory and Harry reached the Triwizard Cup at the same time and decided to take hold of it together. When they arrived in the dark graveyard instead of near the crowd they were confused and stepped away from the portkey just before Voldemort said "Kill the spare," and Wormtail performed the Killing Curse on Cedric (GF32).
- Harry's blood was used to resurrect the Dark Lord, then Voldemort planned to kill Harry and probably return to Hogwarts using the Triwizard Cup portkey. But as he and Harry dueled in front of the Death Eaters, the twin phoenix feather cores of their wands created a "Reverse Spell Effect" known as Priori Incantatem and spirits of Voldemort's previous victims came out of his yew wand and protected Harry, including Cedric, Bertha Jorkins, Frank Bryce, and Harry's parents, James and Lily Potter. With their help, he was able to rush back to the portkey and take Cedric's body back to the school with him (GF34).
