A group of Viking warriors return from a voyage of pillage and slaughter to find their homeland laid waste. Fimbulvinter, the epic Winter prelude to Ragnarok, has begun: brothers kill brothers, the people go mad and the countryside has fallen under the spell of a foul beast. The band of warriors set out on a quest to slay the creature.

A mysterious egg contains an impish creature who can grant great power, for good or evil. Brendan Bean, a kindly family man, finds himself face to face with the bizarre creature, and before long a friendship for the ages develops. Meanwhile, the depraved Benny Piazza leads his deranged militia on a violent quest to reclaim the magical homunculi.
