Plot
Age of Apocalypse Prelude - Collects Uncanny X-Men #320-321 and X-Men #40-41.
Tthis TPB serves as a plot progressing set up of the Age of Apocalypse storyline. Professor Xavier's son Legion travels back in time to kill a young Erik Lensherr (Magneto) in hopes of making his father's dream of peace come true. Not far behind him are Bishop, Iceman, Psylocke, and Storm who are trying to stop him. In the meantime, a displacement with the M'Krann Crystal is slowly causing the world in the present to come to an end. Here we see Cyclops, Jean Grey, Professor X, Gambit, Beast, Rogue, Archangel, and Cable await the end of the world. The ending is tragic in scope, and with Xavier dead in the past there was never a team of X-Men to stop Apocalypse from taking over North America and most of the world. This is the beginning of the Age of Apocalypse storyline which would have a four month run on all the X-titles; showing us Magneto forming his X-Men to stop Apocalypse, along with a time displaced and older Bishop trying to restore the right reality. The AoA storyline was bashed by many a reader, but I for one loved it, and X-Men: Legionquest collects the entire prelude to the cataclysmic event. If your going to start reading the AoA storyline, this is the best place to start.
