Prologue

Late 2062

HJP's POV

Life can change a lot depending on perspective. You change a comma and you can kill black men or you can kill, black men. Something so simply, yet, the whole life can change with that.

That's how alternative world work, actually. A simple change, just alike a comma, and everything's different.

Harry watched as his friends fell down, dead. Yet, what he wouldn't do to actually be able to change that comma right now. To not stay here. To not be forced to watch his dead friends. Everyone he knew… dead.

He glared up at the Muggles. Five years after the Dark Lord Voldemort died it become public that magic was real. Within less than ten years, Harry become the only still alive Wizard. It was a complete massacre.

After the Wizards and Witches came the Magical Creatures and before Harry could think, the Earth started dying as well. That had been what the Muggles hadn't thought about. Earth could keep up without them, but it couldn't without the magic.

In a desperate attempt to secure life, just as Harry felt the Earth's core start to fade, his own heartbeat stopped beating.

Just for then it to restart decades prior…

–LSE–

Late 1932

The raven-haired male opened the new shop in Hogsmeade village. Anything to be close to Hogwarts, the last place to fall to the Muggles before Earth used the last of its powers to send him the last son of Earth to the past.

The only safe place on the whole world. All the others had fallen within the first year. Yet, Hogwarts had lasted half a century…

Life had died in the future thanks to a Wizard now protected by the school wards. Because of his prejudice.

Decades of fighting, of not having anyone who to speak to, of even the portraits stopping moving, the green-eyed had forgotten his own name or worse the name of the Wizard who would create their death.

Yet… he pushed his glasses up his nose. He would find him and stop him before a repeat would've make a comeback.
