Hawas

A gas giant with currents of winds flowing across the planet. Humanoids like Aarakocra, Air Genasi, Kenku, Hadozee and Owlins make their home on floating cities suspended from balloons.

Continents

The Cyclone. an area where the winds clash into a mighty cyclone that sucks everything down to the core of the planet.
The Drifts. a gentle flowing band of wind that slowly circles the planet's equator. Most of the cities on the planet are riding this stream.
Misty Flows. Lower flows of the southern stream of wind. It moves through the mist of the planet and all that moves on the stream is obscured in a fine mist.
Shifting Winds. ruined cities and debris flow in the violently shifting winds of this stream.
 

Cities

Galenaria. The largest city of Hawas. It rides the stream of the Drifts on top of large balloon platforms lashed together with ropes and cables. Great sails have been built on the city to help steer it and ride the winds.
Xarax. The city of floating rocks build on the outside of the Cyclone forever spinning around the outer edge of maelstrom. Magic engines keep it from being sucked into the eye of the storm itself.
The Great Parade. A large collection of airships, big and small riding the Misty Flows. All the vessels are brightly painted and covered in lights to make them stand out in the mists.
Ruins of Xanthar. The remains of the ancient city of Xanthar. A city created by an ancient race of squid like people who were said to be able to control others with their minds.
