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.

Welcome player to the Gates of Niflheim crafted for you by the creative team at Raybox games.
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.

The innovative Paths Unknown game engine powers this system by seamlessly blending popular "dungeon crawl" style games with the storytelling and branching decision making of the choose your own adventure style books of the past.

Paths Unknown creates a new hybrid method of play where the tabletop game experience no longer ends up sprawling across a giant table using a network of tiles and is instead contained within a book that keeps the focus to the play area representing your heroes current physical location within the adventure.

Bound together within a spiral bind book designed to sit flat, the individual "play pages" of your Paths Unknown adventure will show the rules of the location your miniature must navigate on the LEFT page of the open book. As well as displaying the actual physical game board the model will move and fight on the RIGHT page of the open book.

Paths Unknown is a non-linear adventure. Meaning the direction or EXIT your miniature hero chooses to leave a play page, will then decide which new page within the book they will travel to and experience, as the next part of their adventure.

Each play page your miniatures travel to will manifest their own unique perils and challenges giving the model's the opportunity to gain new items, resources and skills, as well as perhaps finding new companions to aid them in their quest.

Gates of Niflheim is the 3rd game in the Paths Unknown system and takes an exciting detour away from the Zombie infested trenches of World War 2 to venture down a path inspired by Viking lore!

Yet again a team of extraordinary heroes must set aside their differences to confront a greater threat to humanity.
