Our heroes finally arrive at the Menean Empire, chasing after rumors that a primal beast has been spotted, but it seems they have come at a bad time. The empire is at war with the goblins, who control the dormant primal beast Hekatonkheir on their home base of Ombre Island. The crew joins the anti-goblin force upon hearing the news, hoping to reclaim the so-called, Light Titan.
They are joined by the mercenary Feena, as well as Lucius and Teena, a sibling duo who have sworn revenge against the goblins. The team is ready to go but the goblins strike first! The airship is under attack!
