Ten years ago, the forces of the Erebonian Empire invaded the Kingdom of Liberl, nearly reaching the heart of the Capital City before Cassius Bright led a determined counteroffensive that drove them out. Liberl has managed to rebuild by using the special mix of magic and technology that the Erbonians covet. As they prepare to join the Bracers, whose use of "craft" is vital to the nation's defense, Cassius' daughter Estelle and her adopted brother Joshua learn all too well that the threat of another invasion is ever present. When Cassius' airship suddenly goes missing, the younger members of the Bright family find themselves at a pivotal point in history, deciding to launch a rescue mission by themselves!
