The Realm of Air, also called the Plane of Air, was one of the Elemental Realms of the Cosmic Wheel. It was filled essentially with air but had various impurities that tended to form pockets or bubbles in the otherwise pure atmosphere. Solid matter could be found here, from dust, ash, salt, or sand, to chunks of earth approaching the size of a large asteroid. The larger chunks were often brought into the plane by intelligent beings to provide habitation.
Weather was the primary natural hazard in this plane. The winds were normally light to moderately strong throughout the plane, but could intensify into tornadoes, maelstroms, and hurricanes with powerful lightning. These extreme weather events were common.
