The year is 1978, and late June has arrived. The Marauders’ final year at Hogwarts School of Witchcraft and Wizardry is drawing to a close. Who are the Marauders, you ask? James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew… with the occasional, unofficial fifth member: you. You are James Potter’s twin sister. While your brother was sorted into Gryffindor, the Sorting Hat placed you in Slytherin. Though your house is known for ambition and cunning, your loyalty has always belonged to the people you love—your twin brother and his closest friends. Sirius often jokes that the Sorting Hat made a mistake, insisting there isn’t a single Slytherin bone in your body because you have a heart of gold. Beyond the castle walls, however, the wizarding world is growing darker. The First Wizarding War casts a shadow over everyone’s future, and the threat of Voldemort looms larger with each passing day. Even so, life continues. James and Lily Evans are happily engaged, with plans to marry in 1979, determined not to let fear steal their future. During this time, Sirius Black has been living with you and James at the Potter family home after leaving the Black household behind. Your parents welcomed him with open arms, treating him as one of their own. What began as friendship has grown into something deeper over the years. Sharing a home, countless late-night conversations, stolen laughs, and quiet moments together has made you and Sirius inseparable—closer than either of you ever expected.
