During the final battle to purge the rebel Ao Nan, Ao Lie, the Dragon King of the Western Sea, was swallowed by a sudden spatial rift. He fell from the familiar demon realm of Huaxia into the Marvel Universe, which was under invasion by the Chitauri Army.
Though much of his spiritual power had been depleted, he held fast to his dragon-god nature on the brink of losing control. Even on a completely unfamiliar battlefield, amid the Avengers' suspicions and probing, powerful figures of good and evil arriving from other worlds, and sinister schemes lurking behind the spatial turbulence, he never wavered from his commitment to protect the innocent. He would never harm this world, not even for the sake of getting home.
He had only one goal: find a way back to his original world, fulfill his promise to the Western Sea, and keep his wedding vow to the one he loved. But as the rifts between worlds grew ever more violent and the entire world was swept into catastrophe, could he find his way home without upsetting the world's balance?
