Many moons ago, birds migrated to the mysterious, deeply magical island of Aerysia. Now, they are recognized as the six flocks: Tidecallers, flock of the Aquarions, Leafbound, flock of the Viridines, Rivervine, flock of the Aquiflorians, Ashwing, flock of the Emberclaw, Iceheart, flock of the Frostvein, and Skyborne, flock of the Celestians.
But when the Nightshade Order, a mysterious cult of the Umbracrest (birds with shadow magic that cannot be countered) on the barrier islands threatens the flocks and Aerysia, it's up to six birds, one from each flock, to gain a mysterious power from their ancestors, the Lun'ariel, and save the flocks before it's too late.
