It's been eight years since Aurelia Beaverdam left Hogwarts, ten years since the Battle of Hogwarts. Aurelia has moved in with her best friend, Hermione Granger, in London and is working as the Head of the Auror Office at the Ministry of Magic. She didn't have the intention to ever go back to Hogwarts and when she was asked to come back by Headmistress McGonagall she really didn't expect to see an old friend again.
