The Legends & the Stooges of Fate

DrT is not a great fan of where Rowling left us after the sixth book. That might be an explanation for this startling one chapter story. It tells the end of the story. Harry fought through the seventh year as hidden „third forth“. On a planing meeting of the Death Eaters on the ministry he kills everyone but Snape. Then he follows Snape to Dumbledores hideaway, who was not yet killed after all. Harry explains that Dumbledore played on destroying Voldemort by destroying Harry. Harry kills him, sends Snape one to Voldemort who kills him. Then Harry follows again and kills Voldemort.
There was a surprising Death Eater Harry did not kill because she showed regret: Hannah.

Harry’s Second Chance

At the end of Harry’s seventh year Voldemort is defeated; but at what costs. Virtually everybody but Harry and Luna are dead. Therefore Luna finishes a spell that her mother started 8 years earlier to send Harry back in time to give him a second chance. It works, although Luna dies but on the ‚bright‘ side the ghost of Hermione returns too. So Harry goes through all this again but with superior knowledge and all his magical power. Therefore all Horocrux‘ are destroyed at the beginning of Harry’s first year. In the summer after his third year he defeats Bella and Voldemort – who is her second – in an official duel. Afterwards he and Hermione, with whom he is magically bonded, disappear from Britain.
DrT writes:

The Last Battle has been fought, and Harry Potter has won. The price, however, has been high. Nearly every person Harry cared for is dead, maimed, or otherwise injured. The magical culture of Britain might never recover. Luna Lovegood, however, knows a secret which will give Harry a second chance, a chance to make a better future for himself and for most of the people he has cared about.

In the process of doing so he introduces them to the Old Belivers that separated them self from the rest of the magical world between 300 and 400 and emigrated in 1500 to North America.
