Two thousand years ago, Yulia made a pact with Lorelei, the aggregate sentience of a force known as the Seventh Fonon. The result was a prophecy known as "the Score" that records the entire planet's history from creation to death. The Score became the basis of the world's central church, the Order of Lorelei. In the present day, Luke, the son of a duke of Kimlasca, encounters Tear, a woman seeking to kill his mentor, Van. But when their Seventh Fonons resonate, both are transported to Tataroo Valley. On their journey home, Colonel Jade of the Malkuth Empire asks them to help deliver an official entreaty for peace. Luke agrees, and travels to the city of Akzeriuth as a goodwill ambassador. Once there, he is tricked by Van into unleashing the power of his hyperresonance, destroying the city and sending Luke plunging into Qliphoth. There Luke meets a boy named Asch who appears identical to him. After Asch tells him a shocking truth, Luke resolves to atone for his past sins by becoming a different person.
