Long ago, the world of Circadia pulsed in perfect rhythm, each habitat watched over by its guardian spirit. But when Day lingered too long and Night grew restless, the guardians strength began to fray. By weaving the powers of spirit creatures into harmonious gatherings, you will restore their connection to their habitat. In Circadia, a game by Hisashi Hayashi, players compete to restore balance by creating sets of Spirit Creatures to claim Habitat cards and gain Balance points. Once a player reaches 15 Balance points, the end of the game is triggered. The player with the most points at the end of the game wins!
