The Order led the fight against Voldemort in the fifth instalment while the Minister of Magic refused to accept the return of Voldemort. In "Harry Potter and the Order of the Phoenix", some Order members take turns guarding Sybill Trelawney's prophecy, which referred to Voldemort's downfall and Harry's role in defeating him. Rubeus Hagrid, the Hogwarts Grounds Keeper and an original Member of the Order, was accompanied by Olympe Maxime in an attempt to recruit the giants to the Order's cause. Some members also participated in a battle at the Department of Mysteries near the end of the fifth book. Order members patrolled Hogwarts, the Wizarding school, on the night of Dumbledore's death in "Half-Blood Prince", fighting the Death Eaters who managed to enter the castle.
