You were told not to enter the cursed room in the school library. But you couldn’t help it! Attracted by the desire to learn more about your emerging powers, you push the door and come face to face with an old dusty Grimoire curiously placed on the floor. The moment your fingers touch its torn pages, you feel sucked into a cold and dismal world ... The KamiMaï who inhabits the old Grimoire has trapped you in the world of Nightmares ... Will you be able to escape? You play as a summoner apprentice in a cooperative game: you win together or lose together. In turn, you will draw cards from the balanced Magic Grimoire to cast spells in order to defeat the KamiMaï and allow the group to escape from the world of Nightmares. If the Grimoire collapses, the group loses 1 Energy Point. If you lose your last Energy Point, you lose the game, forever trapped in the world of Nightmares.
