Great scholars have spent lifetimes uncovering the secrets of the Cthulhu Mythos. As one of those scholars you discover the sealed gates. Unlocking those sealed gates becomes your only desire. Using spells and manipulating the magical power found in the crystals you begin to summon creatures, other cultists and items of great power. With each step you become more powerful but as you probe further into the strange world of the mythos it takes you closer to insanity! In Shards of Madness players compete to summon the most valuable objects and creatures. The player who manages to obtain the highest value cards after six cards have been summoned from the gates wins the game! —description from the designer
