It was your seventh-year at Hogwarts. You wanted to try out for the Tri-Wizards-tournament and got in. You will have to capture an egg from a dragon, find one person at the bottom of the Black Lake with cruel mermaids around you, and you will have to navigating a dangerous, enchanted maze to find the Triwizard Cup. You will also get to go to the Yule Ball with a person of your choice after the first task and before the second one.
