It's been 150 years since the Great War, and the First King is now nothing more than legend. Alchys Darien has spent those long decades in the shadows, working as the Head Servant of the royal palace in Arrowyn -- and with a neglectful king and a prince whose coronation is long overdue, the kingdom has began to deteriorate.

But on the night of the Three Moons Festival, the unspeakable happens: darkness siezes the kingdom, forcing Alchys and Prince Zelan to flee to Theisia, the Realm of Magic, to request the aid of its inhabitants. . . but with Agliah's forces devouring the human realm, they must act quickly before it's too late.
