A blanket of icy mist has covered Midgard since ancient times, forcing small tribes of mankind to eke out a fragile existence in a world dominated by giants and trolls. Odin, jarl of one such tribe, has lost his father to a frost giant, and he will do anything for vengeance. Even turn to the stranger, Loki, who promises to guide him to the monster's lair. But Odin soon finds vengeance is only the beginning. His actions draw the attentions of a goddess who offers him and Loki the chance at immortality. She would have him challenge her own people for control of Midgard. But before he can march on gods, Odin must make his own people see him as one.
