Powers Of X #5 by Jonathan Hickman

Shifting across eras, this chapter reveals the construction of a new, redundant Cerebro system to copy and restore mutant minds—laying the groundwork for resurrection—while, in the far future, a post-human society petitions the Phalanx for “ascension” and confronts the grim reality of what that acceptance entails. Data and deals made with a genetic archivist and a technological genius tie the plan together, illuminating the architecture of mutant immortality and the cosmic machine hierarchy that threatens to subsume all life.
