Arthur roams the frozen frontier as a hardened mercenary, accepting bounties on supernatural entities without questioning the ethics of the guild. His routine turns deadly when he tracks down Ella, an outcast carrying an ancient cryogenic relic embedded near her heart. Instead of executing the mark, Arthur realizes Ella's relic is one of three sacred keystones keeping the apocalyptic wolf god Fenrir bound beneath the ice.
With the fanatical High Priest Odinson dispatching inquisitors to breach the seal and plunge humanity into eternal winter, Arthur chooses to protect the girl. The unlikely duo traverses treacherous peaks and monster-infested caverns to recover the remaining shards. Arthur must risk his mortal soul in combat to prevent the zealots from releasing global devastation.
