In their third year at Hogwarts, a darkness fell over the castle. Dementors guarded the grounds, and everywhere people whispered the name Sirius Black — the escaped murderer from Azkaban. To most students, he was simply a threat. But to Harry Potter and y/n, he was family. Professor Minerva McGonagall warned them both never to trust Sirius or let him contact them, because Sirius was not only Harry’s godfather, but also y/n‘s uncle. Yet while Harry feared the name Sirius Black, y/n felt something else entirely: that behind all the fear was a truth nobody at Hogwarts dared to speak about — and that this year would change everything.
