This entire issue takes place in X^2 (Year One Hundred) and Hickman finally tells us all about the X-Men in this time period. The roster and genetic makeup of the team is:
Apocalypse
War aka Wolverine (James Howlett)
Death aka Xorn (Kuan-Yin Xorn)
Pestilence aka North (2nd Generation Chimera made from Lorna Dane and Emma Frost's DNA)
Famine aka Krakoa / Doug Ramsay
Cylobel (deceased) (Hound)
Rasputin
Cardinal (made from Kurt Wagner, Jean Grey, and Freeman's (Ajax?) DNA)
Percival (deceased) (pureblood mutant)
Mother
Here are the events of the issue:
North, Xorn, Rasputin, and Cardinal attack The Church of Ascendancy at The Temple of Concordance. Omega and her sentinels intercept them, which creates a distraction at the Tower of Nimrod that allows Apocalypse, Wolverine, and Krakoa / Doug Ramsay to infiltrate its data centers. Krakoa /Doug Ramsay finds the information the X-Men are after on a data crystal, but Nimrod discovers their presence and attacks them.
Cardinal consumes a Seed of Apocalypse which negates his pacifist tendencies, but Omega kills both him and North. Xorn is also mortally wounded, so Rasputin removes Xorn's helmet which unleashes a singularity that kills her and Omega.
Apocalypse gives the stolen data crystal to Wolverine and tells him "You know what to do with it." Krakoa / Doug Ramsay opens a portal back to Asteroid K as Wolverine flees through it, leaving Apocalypse to fight Nimrod alone.
Wolverine returns to Asteroid K and opens the Obelisk that we saw in the previous issue. Moira X aka Mother is inside. Wolverine deposits the data crystal into her and she absorbs the origin files of Nimrod. She then tells him, "I have what I need now. And this...this is what you do."
Wolverine then kills her.
"So ended the ninth life of Moira X."
X^2: Year One Hundred has been Moira's ninth life, not an alternate future. Her entire purpose has been to retrieve the origin files of Nimrod in order to finally stop him in her tenth life.
