The Empire's flying city has turned the war decisively in one direction, and the southern mainland nations have signed peace agreements to avoid worse consequences. The city-state union of Caldis continues to resist a demon invasion regardless. The Empire and the church state jointly establish an elite coalition academy at the ancient city of Adar to coordinate the defense. It is here that Medes's long-wandering eldest son is summoned home to lead the female knights of the southern countries against the demon threat. A fantasy strategy RPG.
