This is a Harry Potter story added to [Western Crossover] You Weirdos, Stay Away from Me.
William woke up again to find himself in the Harry Potter world. The good news was that he could finally learn magic. The bad news was that he was in the Marauders' era, at the height of the Dark Lord's power.
After spending four relatively peaceful years as a Slytherin prefect, William finally heard some familiar names at the Sorting Ceremony: the James Potter quartet, Barty Crouch Jr., Severus Snape, and others. William knew the story was about to begin.
