Cedric lives, forcing the Ministry's hand in believing Harry's story about the Dark Lord's return. With the element of surprise gone, Voldemort's supporters attack-- and win. With the Ministry overrun by Death Eaters, Hogwarts and Hogsmeade come to be the only safe places still left. Except that spies and double agents are everywhere, working to undermine Dumbledore's-- and the Order's-- influence at Hogwarts. With the water contaminated with inhibition-reducing potions, Hogwarts descends into chaos.
