Fiction:The Firmament/Plane of Air

The Plane of Air is one of the four regions of the Elemental Plane, currently ruled by the haughty elemental lord Constarnach.

Description
The Plane of Air is a nearly unimaginably large expanse of open skies, filled with churning air current, drifting clouds, and towering thunderheads. Near the borders of the Plane of Water, tremendous storms of rain and snow lash massive globules of water hanging suspended like floating oceans. Solid matter is rare in this realm, much of it consisting of ice, magically solidified clouds or conjured rock. Those who 'fall' in the Plane of Air do so eternally, until they expire.

Inhabitants
Air elementals call the Plane of Air their home, and generally tend to defend it aggressively against any intruders, be them other elementals or outsiders. Due to the plane being largely made up of open sky, creatures unable to fly do not last long there.

The sky wyrms are the True Wyrms native to the Plane of Air.
