The story takes place on the continent of Auskofin, facing a freezing winter era. The great god Odin was concerned that Yggdrasil, the world tree symbolizing abundance, was in the hands of the demonic race. Therefore, Odin ordered his Valkyries to gather a select group of warriors. The peerless hero Roland became the commander of the army and embarked on a sacred mission. Before the snow and ice close everything off, will they be able to recapture the sacred land?

In Roland's hands are a holy sword forged from the fangs of an evil dragon and a celestial wheel that binds and enslaves souls. A survival war chronicle involving gods, demons, humans, dragons, and all races begins.
