Lily Potter receives a warning not to let Voldemort find out about her child; Voldemort goes to kill Neville Longbottom on Halloween, but he did not realise how unstable his soul was, which lead to a complication that weighs on his mind even as he succeeds in taking over Wizarding Britain. Follow the highly intelligent Harry as he makes his way through a Voldemort-ruled Hogwarts.

The final battle doesn't go as planned. At the moment of victory, time sand is thrown onto the dueling pair and Harry wakes up in Tom Riddle's Hogwarts, with no way of getting back. He must find a way to return to his time, all while fending off Riddle's suspicions and amid the threat of Grindelwald's powerful army, whose leader seems to have a horribly familiar fixation with him.
