A game about building nightmares so terrifying you’ll see half of them in your dreams afterwards. You have cards representing Night Terrors, and the more of them you combine in the right order, the more monsters will come to life, and the more horrifying they become. Create monsters that will make your opponents gasp in horror. Nourish them with your own fear and make them stronger. Only then will you achieve victory and become the Master of Terror!
Each Night Terror is also associated with one of four Legions of Horror: Necromunculi, Constricti, Mansters, or Chimeridae. A Terror's legion is indicated by the color of the card's background: blue stands for Necromunculi, brown for Constricti, green for Chimeridae, and red for Mansters. A creature can be made up of any Night Terrors, but players are better off weaving Creatures out of cards that all belong to the same legion. The game continues until one of the players completes five Creatures—this player immediately becomes the winner.
