In a parallel world, Harry Potter has a twin sister named Hazel.
On Halloween night in 1981, Hazel mysteriously disappeared without leaving a trace. After that, almost no one remembered her real name. The Boy Who Lived became famous, and people soon forgot all about her, as if she had never existed.
Unlike the oblivious masses, Harry never stopped thinking about his missing sister, even as he fought with all his might against Voldemort's dark forces. Time passed quietly, and soon it was 1994.
Everything began to take an unusual turn with the Triwizard Tournament.
One strange thing followed another. Right in front of everyone, the Goblet of Fire spat out a fourth name. Then the flames turned green again, and a fifth slip of parchment floated down.
The fifth champion.
Unlike the famous Chosen One, this was an obscure fourth-year student from Beauxbatons. Doubts and jeers came raining down on the two of them, and all of Hogwarts was in an uproar. But no one could have imagined that beneath all the commotion, a conspiracy far darker than anything they knew was quietly closing in on them.
P.S. This follows the original work. The canon characters will all follow their canon pairings, and no one will be whitewashed.
