Sword of Mana, the prequel to the Mana series, tells the story of the source of all life, the power that flows from the goddess Mana and bears her name. Long ago, in a time of darkness, a mighty empire tapped its energy to dominate the world. In an effort to stop the use of such power for evil purposes, a woman from the Mana tribe transformed herself into the Mana Tree, locking the power away from anyone who would try to abuse it. The hero, the young leader of the Duchy of Grantz, has been raised and trained as a gladiator in the slave pits of Grants. The heroine in this story is a young woman from the Mana tribe who possesses deep ties to the goddess Mana. As the Shadow Knight is persecuting the Mana tribe, the heroine embarks on a journey to protect it. When the hero and heroine meet, the wheels of fate are again set into motion.
