The leader of the Avalon Principality, Duke Zeira is a humble man who rides his nation with a velvet glove instead of an iron fist. Under his savvy direction, the Avalon Defense Force has somehow managed to hold the Imperial Army at bay, but he knows that time is running out. He places much trust (and responsibility) upon his inner circle of military personnel, including Kaidul, Ione, Reyna, and the laugh-a-minute Galvas.
