Premise
Voldemort never had the time or the inclination to make horcruxes. He died with Quirrell in May 1992.
In June 1992,as the Wizarding World celebrated Voldemort's final death,Amelia Bones led a coup that instated Rufus Scrimgeour as minister of magic. She also had Sirius Black brought before the Wizengamot,as he hadn't had a proper trial. They judged him innocent.
The Triwizard Tournament was held in 1993 and 1994,at Hogwarts, but with Ilvermorny substituting for Durmstrang as that school was undergoing an administrative crisis following the suicide of Headmaster Igor Karkaroff. Fleur Delacour was the Beauxbatons champion,Angelina Johnson was the Hogwarts champion,and Jaime Anders was the Ilvermorny champion. Hogwarts won the championship.
And that is where our story begins.......
