The island of Genosha was once a thriving nation of mutants, built from the ground up by Magneto, Master of Magnetism. Then, one day, an apocalyptic attack killed every man, woman and child, and reduced an entire society to rubble within hours. Now, Professor Charles Xavier - legendary founder of the X-Men, and the man who dreams of peaceful coexistence between humans and mutants - has come to Genosha wih one intention: to rebuild a nation from its ashes. But certain people would prefer that Genosha stay destroyed - and are willing to make sure that the nation of mutants doesn't rise again!
The Magistrates were once the human rulers of Genosha... and now they want it back! Professor X and his ragtag team find their first major test as they're faced with an attack from all sides, but some unlikely allies wait in the wings as well. This is the moment when Xavier's Dream hangs in the balance, and the team must decide whether they will draw the sword and accept the challenge... or surrender in the fight for mutantkind!
