Guest-starring Dr. Strange! Professor Xavier must call in the help of the Sorcerer Supreme to deal with the increasingly dangerous, reality altering madness of Wanda Maximoff, a.k.a. the Scarlet Witch. And perhaps even more dangerous is the grief and desperation of her father, Magneto.
Plus: Callisto answers a cry for help from Warren Worthington, a.k.a. Archangel! But Callisto and Warren have some pretty unpleasant history between them... can they overcome their differences long enough to survive?
