For the past 24 years, Harry Potter had been able to live a fairly normal life by wizarding standards. However, on December 31, 2022, 100 years after the birth of Voldemort, Harry's life takes a strange turn when people from Harry's past suddenly begin reappearing.

A year after the Battle of Hogwarts, Harry Potter was nearly finished with his time at Hogwarts, was happily raising his godson Teddy, and was actually beginning to forge a connection with someone he had been certain was an enemy. After finally beginning to feel comfortable with his post-war life, Harry's life is thrown into disarray yet again when people from his past return.
