From publisher blurb:
To Reign in Hel: A Sagas of Midgard Adventure for Heroes 60-100 SP.
In the land of Agder there is a valley filled with impenetrable Mists; travelers give them a wide berth, as legend states that none who enter the Mists ever find their way out. Until now, of course. Whether by accident or design, you will find your way into the Mists, taking you deep into Niflhel, the accursed world of the dishonored dead. Complicating your attempts to escape will be the Lords of Niflhel, who seek to tear the Heroes apart by trickery, deception, and an Artifact of great power that exerts a disquieting amount of control over whomever wears it.
