Story Overview – Odin watches over all 9 realms from atop the Tower of Valhalla within Asgard. Many evil beings wish to conquer Asgard and take over Odin’s reign. To prevent this, Odin has set up the tower as a stronghold against any foe. Many of the 1337 floors of the tower are guarded by one of Odin’s Protectors, who are the strongest warriors in all of Asgard. The higher the floor, the more powerful the protector.
