X-Men

The War of Kings is the culmination of years of Marvel cosmic storytelling. The Inhumans, led by Black Bolt, have taken control of the Kree Empire. The Shi'ar Empire, under the rule of the mutant Vulcan (Gabriel Summers, Cyclops's long-lost brother), is expanding aggressively. The collision of these two cosmic empires draws in the Guardians of the Galaxy, the Nova Corps and X-Men-adjacent characters across the Marvel cosmic universe.

The House of M reality — where Magneto rules and mutants are the dominant species — touches every corner of the Marvel Universe. Spider-Man is a celebrity. Captain America never went into the ice. The Hulk was sent off-planet. This companion omnibus collects the tie-in series that show what House of M's altered reality looked like for every major hero, providing story material that makes the main event's conclusion hit considerably harder.

The Scarlet Witch has a breakdown. Her son reminds her of what she's lost — her children, her sanity, her place in the world. She whispers three words: 'No more mutants.' Reality reshapes. In an instant, the mutant population drops from millions to 198. House of M collects the complete Brian Michael Bendis-written event that permanently altered the Marvel Universe and set the X-Men's direction for nearly a decade. The complete M-Day story in one volume.
