The Sky Realm; a sea of clouds and floating islands.
One mystic island, Zinkenstill, is home to the boy Gran and his winged friend
Vyrn.
One day, they encounter Lyria, a mysterious girl who fell to Zinkenstill when
fleeing the militaristic Erste Empire.
Gran, Vyrn, and Lyria set off into the skies to escape from the Empire.
Serving as their guide is a missive from Gran'sĀ father, who waits in Estalucia,
Island of the Astrals.
