Not serious - in the magical world at the peak of Grindelwald, there are no cheats for time travel! Serious - the story begins before the plot of Harry Potter, and a few years after the ending of 'Fantastic Beasts and Where to Find Them'... ..That year, the first-generation Dark Lord summoned the saints who followed him at Père Lachaise Cemetery. That year, the second-generation Dark Lord had just been born. That year, the greatest white wizard in history was just a Transfiguration professor. This year , an orphanage outside London, our protagonist Sypha Corwin was born... PS: Hogwarts, Harry Potter, Wizards, Wizarding World, Grindelwald, non-original plot, with hundreds of millions of changes
