As Iron Man fights for his life in the distant past, the Avengers face an uncertain future! Trapped in an icy cave at the dawn of time, Tony Stark has lost most of his armor -- and a good chunk of his mind. When the sun goes down and the devil comes around again, he may lost whatever's left of his soul. And in the present, Earth's mightiest villains unite! What do the king of Atlantis, the lord of vampires, the deposed duke of Hell, a mysterious Russian assassin and the secret boss of Wahington D.C.'s greatest super-team, have in common? They all really hate the Avengers! Worse still, mummies are rising from their graves. A dark god has invaded Asgard. And Moon Knight is unleashed! So begins the Age of Khonshu. So fall the Avengers!
