Gathered together by telepath Professor Charles Xavier, the X-Men are sworn to protect a world that fears and hates them. Now, their mentor is missing, and the X-Men find their ranks divided between two worlds, both of which teeter precariously on the brink of destruction. Thought light-years apart, can the X-Men come together to save both the fervid jungle of the Savage Land and the star-spanning Shi'ar Empire? Or will both worlds -- and their mutant defenders -- be lost forever?
