The elemental plane of air is a universe of glorious blue sky, pure air, and fair winds. This plane is most congenial to human visitors. Visitors can fly using magic, or choose a direction to free-fall.
Arrows never fall, but slow to a halt over a few days.
Elementals from this plane excel at creating destructive windstorms. Elemental servants from this plane excel at aerial reconnaissance, missions in civilized terrain, and kidnapping. Air genies are mostly a pleasant lot. Invisible stalkers and aerial servants own large estates. There are realms devoted to aviation.
