Long ago, when the world was at peace and magic yet unknown to man, a beautiful isle called Illusia floated in the center of the Inner Sea. Over the island towered the great Mana Tree, the source of all life.

There it had stood since the dawn of the world... But over time, the tree gradually turned to stone and slept as though death had come at last.

So begins the story of how a boy came to wield a sacred sword and how a maiden became a goddess entwining the fate of spirits, mortals, and the entire world into a tale of hope and despair.
