This is what the Watcher has been watching for! • A danger older than the Earth threatens everything. For once, the heroes who have saved the planet so many times are almost powerless in the face of it. • X-Men and Avengers assemble. Spider-People and Fantastic Four come together. Heroes for Hire fight alongside Champions. • None of it will be enough. • The lights are about to go out. • The world outside our window...is about to end. • An all-new saga of the Marvel Universe as you've never seen it before from Tom Taylor and Iban Coello!
