A simple midwestern farmer makes a deal with the devil so he can exact his revenge for a tragedy that befell him years before. He summons a special little child, one that causes worlds of mutants to collide... literally. Mutants from a myriad of different realities merge into one, and as they fight among themselves, Professor X and Kitty Pryde try to get to the bottom of things. They quickly discover that Illyana Rasputin, Kitty's late best friend, is at the heart of the chaos.
