A long time ago, there was a great conflict between the evil god and the people. After a fierce battle, the people managed to seal off the evil god, but what was left behind was a desolate land. The people thus chose to abandon the land and live in the sky.
Such fairy tales were passed down as legends. At this time, people had wings called Wings of the Heart and lived a peaceful life. It was an era of long-lasting tranquility… But the collapse had quietly already begun.
When a young man calls upon the Guardian Spirt, the story begins to unfold. A story set on a floating continent in the sky, where thoughts and prayers intersect.
In the world of "Baten Kaitos," equipment, weapon, magic, items etc… possess “Magna Essence” that can be sealed on cards and return to their original form when needed. Those cards are called "Magnus” and are completely unique to these games.
Each character has their own deck of “Magnus” cards which they can select to attack or heal. The attack power is determined by the attributes and the combination of the cards which are randomly dealt from the deck.
