When a mysterious wizard from America appears in Britain for his school's participation in the Triwizard Tournament, how will that change the fate of the Tournament and the fate of Britain. OC of course, takes place in 2014, probably HP/DG depending on how the story flows. M because it's better to be safe than sorry!

A talented wizard who forgot his past. A boy who lived and a different situation. A lethal tournament with one too many participants. This is my re-imagined story "The Butterfly Effect." There will be some very different choices. An ice queen will emerge and make her mark on history. Will you join them on their journey? Rated T... for now

Harry Potter does not compete in the Triwizard Tournament, but is a mere spectator. How will an ordinary Hogwarts year affect his preparation for the coming war? Will he carry the legacy of the Marauders or train like a madman? Or both? Will someone new slytherin to his life? Daphne x Harry This story is going to follow Thermodynamics, Time for chaos (relatively controlled ;)
