Constant storms whip across the skies of Uranus. On those wild winds fly the Eyries; floating vehicle-cities. No one lives on Uranus without knowing how to fly, be it with craft or their own wings.
Floating islands are giant rocks carried by the whirling winds of the Aer. Despite their ephemeral existence the islands form the bedrock of Uranian life.
Eyries, the Uranian vehicle-cities, come in many shapes and sizes, from archaic airships, to cart-cities towed by skybeasts, to pollution-spewing motor-eyries, to modern flying fortresses powered by crystal engines.

Rapid winds whip up and around the Aer, the outermost of the three layers of Uranus. It is the home of most Uranians, who live and travel aboard Eyries, or temporarily settle onto the Floating Islands.
The oldest and most grand of Uranus' floating cities, Theseus Eyrie, is the only airship that still drifts through the Aer. She has been in flight for millennia, although scholars argue that her extensive repairs mean she is no longer truly ancient.
The Caelus Eyrie is one of the great floating cities carried by the biting winds of Uranus.
Toxic clouds pool in the Mares, the sea-like depths of Uranus. Boiling gas surges towards the Aer, as frigid waters drag the Floating Islands towards the natural furnaces of Terra.
The Erelis say that you come of age when you realize that there is nothing but a thin hull between you and an endless fall. Sharp eyes keep constant watch, for danger, for omens, for betrayal.
The Parachute Trees are native to the Aer of Uranus, and thrive in the summer pole. They grow on the islands of Uranus. They have a very quick life cycle, growing to maturity in just a few years.
When it is fully powered, the Sword of Clouds lights up sun-gold white. It cuts through bone and flesh as easily as clouds. The Sword can slash through reality and translocate its wielder to where their hearts desire.
The Othello shaft-hole axe head is an ancient artifact most notable for providing rare information about the design of prehistoric axe handles.
Starwatch is the collective defense organization of Uranus that patrols its skies and orbital space.
