Ires and his father, Leglight, are peddlers. Near Gramnoa, they met a genius "tempest" named Yuan. Yuan mistook them for bandits and began to fight. Leglight wielded his mystic weapon and beat him back. However, right after that, he was swallowed into black light, leaving behind the weapon, a "device", and a message: “Visit Oldman in Gramnoa”. To look for his father, he leaves for Gramnoa.
