The original five conclude their X-Factor adventures and return to the X-Men fold! Cyclops, Jean Grey, Iceman, Beast and Archangel are professionals through and through. But when the likes of Sabretooth, a cadre of vampires and a threat from an alternate dystopian future wage war against our heroes, it's no big surprise that things get a little out of control! And when the island-nation of Genosha strikes at the X-Men, the New Mutants and X-Factor join an assemblage of mutants to mount a rescue mission that leads to disaster. With old foe Cameron Hodge pulling the strings, it could even end in X-Tinction! Then X-Factor must contend with the return of Apocalypse and the shocking loss of Cyclops' son, Nathan Christopher - before an ordeal with the Shadow King that leads Scott, Jean, Bobby, Hank and Warren back home to the X-Men! It's the end of an era - setting the stage for a (blue and) golden age!
