Pirates of Skyview
High above the main layer of Aether clouds. Above the floating castle kingdoms of the elemental Genasi or secretive Orders of Gith. Brushing even the bases of the largest of the heavenly Skylands, roars the eternal winds of the Great Barrier Storm.
A storm that encompasses the world, shutting out views of stars and moons alike on all but the rarest of nights to Flatlanders and Uplanders together. The winds scream and whip wildly, tearing apart all but the stoutest of ships under both the steersmanship of seasoned Aeronauts as well as protected by the strongest of magics..
The Great Barrier Storm effectively seals off the world of the Skylands and all the realms below, much to the delight of the elite and isolationist peoples of those lands.
