Into the blue and beyond!

This is 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. Gran and Vyrn one day encounter Lyria, a mysterious girl who fell to Zinkenstill when fleeing from the militaristic Erste Empire. Gran, Vyrn and Lyria set off into the skies to escape from the Empire. Serving as their guide is a short
missive from Gran's father, who waits in Estalucia, Island of the Astrals.
