Powers Of X #4 by Jonathan Hickman

Something Sinister

Spanning multiple eras, this chapter shows Xavier enlisting Cypher to communicate with Krakoa and establish a living mutant language; in the present, Xavier and Magneto coerce a flamboyant Mister Sinister into secretly compiling a comprehensive mutant DNA database, teased by his cryptic “Sinister Secrets”; and in a distant future, post-human stewards petition the Phalanx for ascension by offering a planet-sized singularity, exposing the ominous cost of evolving into higher orders of intelligence.
