Immortal X-Men 4.

Charles Xavier had a dream – now he has nothing. Orchis’ savage strike on Krakoa’s Hellfire Gala was more horrifying than Xavier and the Quiet Council ever could have dreamed. Mutantkind has been all but wiped from the face of the Earth – and it’s partly Charles’ doing! As Sebastian Shaw tries to profit from the tragedy, Exodus steps up to lead his displaced people to a new promised land, but the desert holds many dangers! And Xavier, who swore to stay on Krakoa and defend its memory, is leaving. There must be a good reason he decided to swap one doomed island for another, but dark secrets await him beneath Muir Island! Meanwhile, something is very wrong with Jean Grey – or is it something very right? Being immortal means nothing when you run out of time! Collecting IMMORTAL X-MEN #14-18.
