Immortal X-Men Tome 4

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 ! Now Xavier begins a self-imposed exile and vigil on Krakoa to defend its memory. All is not lost as Exodus steps up to lead the displaced mutants forced through the Krakoan gates to a new promised land, but their desert location is unknown and holds many dangers ! And Sebastian Shaw and Selene seek to profit from this terrible tragedy.
Meanwhile, something is very wrong with Jean Grey - or is it something very right ? Being immortal means nothing when you run out of time !
