Ires and his father, Leglight, are peddlers. Near Gramnoa they encounter a genius “tempest” named Yuan. Yuan believes they are bandits and attacks, but Leglight uses his mystic weapon to drive him back. Moments later, Yuan is swallowed by a black light, leaving behind the weapon, a device, and a message that reads, “Visit Oldman in Gramnoa.” Determined to find his father, Ires heads for Gramnoa.
