In ages past, an island called Illusia floated at the center of the world. At the heart of the island towered an ancient, enormous tree that stretched up to the very heavens. For ages past, chaos and sorrow had engulfed the world until at last its salvation appeared in the form of a boy, a girl, and a holy sword. Time flowed on and peace returned. The sword and the tree remained, and they soon came to be known as the Sword of Mana and the Mana Tree. (Metacritic)
