Apocalypse's long-prophesied ascension begins! As Professor X grows paranoid and withdrawn, the X-Men split up -leaving only a small team to aid a friend. And when Apocalypse's newest Horseman of Death strikes, an X-Man will perish! But not everything is as it seems, and as the team realizes the full scope of Apocalypse's scheme, it may be too late! Only the Twelve, a gathering of mutants foretold to save the world, might turn the tide -but Apocalypse plans to use them to become a god! Who will make the ultimate sacrifice to prevent the Ages of Apocalypse from becoming a horrifying reality?
