Tales of Symphonia

The game begins in the world of Sylvarant, a land that is dying due to a steady loss of mana, the energy source that is needed both for magic and to support life itself. As the crops begin to wither and hardship sets in, the people turn their hopes to the Chosen One, a servant and messiah of the Goddess Martel, who can reverse the ills of the world by completing the Journey of World Regeneration. The current Chosen is a girl named Colette Brunel, who is protected by her childhood friends Lloyd Irving and Genis Sage, her teacher and Genis' older sister Raine Sage, and Kratos Aurion, a mercenary with a mysterious past. Later on in the game, the party is joined by four other people: Presea Combatir, a strong but strange girl; Zelos Wilder, an arrogant playboy that is the Chosen One for Tethe'alla, the other world; Sheena Fujibayashi, a female ninja; and Regal Bryant, an ex-convict.

Such a quest is undertaken when the world is in an extreme state of decline. In order to regenerate the world, the Chosen must travel from continent to continent, awakening the Summon Spirits that sleep at ancient shrines known as "seals". With every seal released, the Chosen comes closer and closer to becoming an angel. Once the Chosen fully transforms into an angel, the world will be regenerated
