War is being waged in Valhalla! Valhalla was a happy and peaceful place until the discovery of the wellsprings. The water from the wellsprings brought power and visions to those that drank from it. The visions included images of heroes and warriors from other worlds and times locked in deadly combat. With their new powers, the Valkyrie devised ways to beckon these creatures and use them against their enemies. The lush lands of Valhalla have now become a war-torn and desolate ruin.
