Emotions run deep in this expansive role-playing game as you play a spirit guiding a young hero, Kalas, to his destiny to unlock the mystery of a lost sea. In the world of Baten Kaitos, lands exist in the sky, and the once-vast oceans have become but dim memories in the minds of men and women. As a sinister conspiracy to usurp power threatens to plunge the world into destruction, Kalas and Xelha meet. You will control a spirit that guides Kalas through this breathtaking world and fights by his side. Baten Kaitos boasts an unconventional card system. In the quicksilver, turn-based combat, you can combine cards to conjure countless magical effects.
