Riddle dairy, the Hufflepuff's cup, the Ravenclaw's diadem, the Slytherin's locket, Marvolo Gaunt's ring, Nagini, and removed the one from Harry Potter.But Hades is through with it and sends the Ghost King and some friends. Four companions must travel to Hogwarts, one for each of the houses. They must find and destroy the final horcrux before He-Who-Must-Not-Be-Named rises again, but brings back with him Greek monsters.
