Now that Adol Christen has saved the land of Esteria from the evil priest Dark Fact, Adol and the two priestesses travel to the floating land of Ys, where evil has an even greater influence on the people and no one has hope. The future of Ys falls to Adol, heir to the powers of the priests and the only one who can show the people of Ys the truth about their world. But, as Adol's power grows, he may be the one who will save Ys—or destroy it.

Mythical beasts lay siege on the people of Esteria, who have raised an army to fight back. The beasts are relentless and seemingly have no end to their numbers, while the population of defenders dwindle in every skirmish. Even in the town of Minea, where the people are safely nestled behind castle walls, the constant attacks have left them hopeless. It is then that a prophecy is made, proclaiming the arrival of a brave young soul that could be the one who will bring their salvation. Ys follows Adol Christin, an adventurer driven by wanderlust towards the island of Esteria, who washes up on shore after a shipwreck. Following the guidance of the fortuneteller Sarah Tovah, he and his allies will travel the island in search of the legendary tomes known as the Books of Ys. It will be a long and perilous journey, but if fate is truly at work then Adol will certainly be the hero who returns peace to Esteria.

Ten years ago, a massive invasion by the Erebonian Empire almost shattered the Kingdom of Liberl, piercing to the heart of Capital City before being driven back by a determined counteroffensive led by Cassius Bright. Now, as the invaders pace behind the northern borders, coveting the small kingdom's magic and high technology, Liberl slowly rebuilds with the aid of the Bracer's Guild, whose mystical use of "Craft" is even more intrinsic to the nation's defense than its own army. For young Estelle Bright, daughter of Cassius, this is all just ancient history that she and her adopted brother Joshua learned as kids. But history has a way of repeating itself, and as they prepare to join the Bracers Guild themselves, sinister forces are preparing to thrust them into the familiar family situation of being in the worst possible place when mayhem breaks out. Because when their father's airship goes suddenly missing, of course it only makes sense to two green, but extraordinarily capable, young teenagers to strike out on a rescue mission of their own!
