One of the most famous eras in X-Men history begins - twenty years in the future, ruled by the evil mutant Apocalypse! Charles Xavier is dead - killed twenty years in the past during a time-travel accident - and the world created by his absence is a nightmare! Apocalypse rules with an iron fist, ruthlessly enforcing his dictum that only the strong shall survive. But hidden in the long shadow of En Sabah Nur is a group of ragtag freedom fighters led by Xavier's oldest friend, Magneto: the X-Men! When Bishop, last survivor of the true Marvel Universe, explains how the world went wrong, these embittered mutants and their tenuous allies must risk everything to put things right!
