The Vorder Kingdom finally has an heir, but the celebrations for the newly born prince Joldy are interrupted by an unexpected invasion.
Azuves and Joldy’s search for the iron giant Galient leads them to White Valley, where a girl called Churull claims to know its location.
The legends were true: Galient appears at long last and turns the tide of battle. Meanwhile, Mardoul entrusts High with a mission of vital importance.
Joldy doesn’t know why Hilmocha kidnapped Churull, but it doesn’t matter. He’ll save her even if it means allying himself with a thief.
Joldy and the others must escape. But with Mardoul’s forces in hot pursuit and High willing to employ any means necessary to capture them, their situation is grim.
While Mardoul orders his forces to wipe out the rebels in White Valley, Hilmocha convinces the group to attack a nearby facility in a high stakes mission.
