Take to the skies to explore the Sky Realm, a world where islands of all shapes and sizes float in a sea of clouds. It is a world forsaken by the gods. Once upon a time, people known as the Astrals attempted to seize control of this world with their overwhelming might, but the citizens of the skies repelled the invaders, thus ushering in a new era of peace.

Living on a little-known island in a remote part of the skies, you find a letter left behind by your father telling you to set off for a legendary island. However, before you leave, you meet a mysterious girl named Lyria, inevitably setting the wheels of fate in motion as you take your role as captain of a skyfaring crew. Joined by Lyria and a scrappy little dragon named Vyrn, sail together with a colorful cast of crewmates, including kings and misfits alike, for Estalucia, a fabled island beyond the end of the skies.                                             

In the Zegagrande Skydom, islands are guarded by powerful creatures known as primal beasts and winds carry tales of a secretive organization known as the Church of Avia. Unveil a web of intrigue reaching far beyond the borders of Zegagrande and engage in a battle for the fate of the Sky Realm itself.
