Plane of Air

The Elemental Plane of Air was an Inner Plane or Elemental Plane of the Great Wheel cosmology model. After the Spellplague, the Elemental Plane of Air collapsed into the Elemental Chaos, mixing with all the other Inner Planes. Air is one of the four elements and two energies that make up the known universe and therefore of keen interest to cosmologists as well as spell casters that wish to harness and wield the raw power of the elements.
According to the Great Wheel cosmology model, the Elemental Plane of Air could be reached via the Ethereal Plane, an adjacent elemental plane, or by an elemental vortex. If traveling through the Deep Ethereal, a blue curtain of vaporous color indicated the boundary of the Plane of Air's Border Ethereal region. Once in the Border Ethereal, a traveler could observe the Plane of Air and be detected by its denizens. Using the spherical model, this plane was adjacent to the para-elemental planes of Ice and Smoke and the quasi-elemental planes of Lightning and Vacuum. Elemental vortices could occur wherever a high concentration or nearly pure form of an element was found and could be temporary or permanent. A vortex to the Plane of Air could manifest in the eye of a hurricane or in the clean, crisp air atop a high mountain, for example. There was a vortex to the Elemental Plane of Water called the Waterspout not far from the djinn city/palace called the Citadel of Ice and Steel. Temporary gates could be created by the plane shift spell or the abilities of high level druids.

Geography

The Elemental Plane of Air was filled essentially completely with air but had various impurities that tended to form pockets or bubbles in the otherwise pure atmosphere. Gaseous bubbles included clouds of every type, fog, steam, mist, smoke, poisonous clouds, and acidic vapors; also the rare intrusion of elemental fire which is flame without fuel. Liquid impurities were usually water or water-based and tended to form floating spheres when not buffeted or frozen by the winds. 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 and were very likely to be inhabited or formerly inhabited. As described by the Great Wheel model, a traveler with a guide could approach the boundaries with the para- and quasi-elemental planes: where the whiff of smoke eventually became hot, thick, and choking, or the tang of ozone soon lead to heavy storms with arcs of lightning in all directions, or the temperature dropped until flakes of snow, crystals of ice, and lumps of hail finally became a wall of ice, or the light faded to gray and the air thinned out until there was nothing.
If you had to describe the Elemental Plane of Air in a single word, it would have been "blue". The very substance of the plane seemed to radiate the magnificent sapphire hue of a clear summer day on the Prime Material Plane. Visibility was twice what the best conditions on the Prime could allow unless of course, something obscured vision. The 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, and when other elements got caught up in the storm it could produce pounding rain, blinding snow, pelting hail, freezing sleet, and storms of choking smoke, biting sand, burning ash, scalding steam, or searing fire. The worst of these was the maelstrom, a toroid-shaped tornado that could last for decades. Being caught in one was like being in a violent dust storm and death was only a matter of minutes away unless the victim was able to achieve great speed (escape velocity), perform an act of great strength, or receive outside assistance. Spellcasting was impossible within a maelstrom.

Ecosystem

Invisible, and yet the most common denizens of this plane were the elementals themselves including aerial servants, invisible stalkers, and wind walkers. Unless magic was employed their outlines were only vaguely visible if dust or debris were caught in their bodies. When made visible, air elementals were usually large wispy beings with aerodynamic bodies and wings, or propelled themselves by forcing air through their bodies and using fins for maneuvering. Others, sometimes called animentals, mimicked the shape of Prime Material animals and monsters.
Immigrants to the Elemental Plane of Air included the djinn, some jann, mephits of the air, dust and ice subtypes, and arrowhawks. Reported sightings of other creatures included beholders, belkers, cloud giants, devas, hippogriffs, ildriss, pegasi, skriaxit, spectres, sphinxes, sprites, sylphs, vapor rats. and genasi.
