On the final morning before graduation at Hogwarts School of Witchcraft and Wizardry, the Great Hall is louder than usual—seventh-year Marauders celebrating freedom, professors trying to maintain order, and the sixth-year Slytherin group of Regulus Black, Evan Rosier, Barty Crouch Jr., Christian Montague, and Xavier Berkshire sitting together in tense silence as the war outside Hogwarts worsens by the day. In the middle of breakfast, the enchanted ceiling suddenly darkens, every door seals shut, and an ancient-looking envelope marked From the Future appears in the center of the staff table. The note explains that everyone in the Hall is about to witness the lives of their future descendants through a series of magical “movies,” and that what they learn will determine whether they survive the coming war—and whether their children inherit a world destroyed by their choices. What begins as confusion quickly turns into shock when the visions reveal Hogwarts in the 1990s and a group of students feared across the school for their infamous surnames: Vesper Black, daughter of Regulus (deceased); Celeste Rosier, daughter of Evan rosier(deceased) cousin to Luna Lovegood through Pandora Rosier(deceased); Roman Crouch,son of Barty crouch jr(in Azkaban) the brilliant but chaotic ; Marcel Montague, son of Christian Montague(alive) sarcastic and endlessly clever; and Lorenzo Berkshire son of Xavier Berkshire(alive) , the calm heart of the group. Though the school expects them to become the next generation of dark wizards, the five are fiercely loyal to one another and quietly spend their years protecting vulnerable students—including Harry Potter and his friends—as they struggle under the weight of the family names their parents haven’t even ruined yet. While the Marauders watch their future children grow up in the shadow of war, old rivalries begin to crack, horrifying truths about betrayal and death slowly unfold, and Regulus is forced to witness the daughter who spends years searching for the father history told her abandoned her.
