Designed by the Origins Award-winning Lords of Waterdeep duo of Peter Lee and Rodney Thompson (see Lords of Waterdeep), the game pits players against each other in a battle to win territory in Underdark, using a mash-up of deck-building and board control mechanics. Players take the role of the head of a drow house, and recruit monsters, cultists and demons to help them control locations including Menzoberranzan and Blingdenstone. Players use power and influence as resources, attempting to infiltrate enemy strongholds and assassinate enemy troops as they vie for control of various areas.The game is for 2 - 4 players, and plays in about an hour.
