What happens when you make an enemy of destiny itself? Althea's homeland seems fated for ruin as she and her companions rush to quell growing civil unrest, all while an army of chimeras approaches. If they can't unite Endellion in time, Althea's country may not survive. However, the mysterious hermit warns of a greater threat, one that could spell doom not just for Endellion, but for the entire world. Joining forces with an estranged friend, the light of hope seems to come within reach, but just as things begin to go their way, disaster strikes again. The vanishing of the moon and the stirring of the primordial spiròts heralds chaos, and the life of a dear friend hangs in the balance.

The hermit, her true identity at last revealed, offers their world a path to salvation, but what will they have to sacrifice along the way? With the secrets of their world laid bare, they will have to unlock the true powers of the elements, the ancient spiròts, and even the forgotten past, in order to stand a fighting chance. Althea, ever in search of her own path, once again seeks a common ground, this time between forces far beyond anything she could ever have imagined. In the end, her choice will decide not only her fate, but those of her friends, and even the world itself.

When many forces collide, those caught in between must accept responsibility for their choices, lest those caught with them be drowned in a vortex of destiny.
