Harry Potter And The Return Of The Dark Lord

One year after the Battle of Hogwarts, and wounds are yet to heal. Families remain torn apart, and many still bear the scars of losing what they loved most. The Wizarding World can sleep soundly at night, knowing Lord Voldemort is no longer in their midst. Or so they thought. "A potion. That's all you need to bring him back. That's all you need to arise a world of chaos." AU.
