Without a home and with floodwaters rising from the melting of the polar ice caps, X-Nation turns to the newly arrived Exodus, who promises to lead them into a new era of power. Cerebra battles the telepath who shows his true colors, wanting to help mutants rise up to rule over humans. In the final battle Clarion sacrifices himself to destroy Exodus and the remaining members of X-Nation evacuate to the Savage Land with the rest of humanity to escape the floods and the coming of the Phalanx.
