The Templar Order, and older variations of it, have protected world throughout the ages. The order had died but Humanity needs it once again so it will be reborn in the form of one boy, Hadrian James Potter, Progenitor of the new Templar Order. He must protect those cannot protect themselves and shield the weak.

Harry Potter an obscurial, makes sense to me. Let's see what happens. Obscurials are dark parasitic creatures from Fantastic Beasts and Where to Find Them. I'm terrible at writing summaries so just read the story if you want to understand.

After Harry Potter sacrifices himself to Voldemort, he finds himself in a void with a disembodied voice. He learns that his life is a video game and tries life again to fix everything that went wrong the first time around.
