Magneto takes the war to Attilan! As terrigen mist circles the globe – igniting the Inhuman race while crippling mutant kind – tensions have been rising between the two races, and when a new inhuman emerges with the power to see the future, the X-Men fear he may tip the scales and spell doom for their kind. Now, one mutant is willing to wage war on the Inhumans, and even his own people, to prevent that from coming to pass – and that mutant is Magneto! But as the master of magnetism takes fate into his own hands, who will join him in an assault on Attilan? What side will the X-Men take? And could it be that Magneto’s action only serve to bring about the outcome he fears?
