Y/N was born into the world of Harry Potter books, so ending up in the same stories she loved, with her favorite characters going to Hogwarts with her? She was in shock at first after being sorted into Gryffindor the same year as the Marauders. Initially, she stayed invisible, making a few friends while pretending to be English, even though she was actually American. Then, the Black twins, Regulus and Maia, started the year after her, and she was shocked because Maia Black never appeared in the books. Having her in Sirius and Regulus's lives changed everything she knew. Maia and Regulus were sorted into Slytherin, but Y/N was friendly with them, as Regulus thought Y/N was beautiful and interesting, even though she wasn't trying to get anyone's attention. Y/N was trying to alter the Marauders’ story from the books for the better while being careful not to reveal her knowledge of Horcruxes. But she was still at Hogwarts, so that plan was saved for later. Now, in her seventh and final year at Hogwarts, she decided she’d had enough of being a wallflower.
