In Gates of Niflheim, an ancient Viking site long since sealed to contain the threat within, has been disturbed by the rapid expansion of the Christian faith. A monastery built right on top of the ancient Viking tomb has unwittingly awoken a perilous supernatural foe of the Norsemen, who now threatens to escape his confinement by passing through the Gates of Niflheim and back into the mortal realm.

But the deepening threat of the site of this adventure has not only alerted the Vikings. The Christian church has also sent heroes to put down this obvious threat to humanity leading to an uneasy alliance between the Viking forces and those warriors sent by the Holy Church.

Within these pages you are invited to become involved in a heroic tale of Mythic Horror, that will test your wits and nerve in the proving grounds of a brand new Paths Unknown adventure.
