Sylph

Sylphs are spirits of the winds. They are the embodiment of the wind, their bodies are formed of wind and air and cloud. When they take human form, they look ethnically ambiguous, and are always exceedingly beautiful. Sylphs have extraordinary power over the element of Air, far more than any witch. They can conjure and even become storms, typhoons, gales, lightning, etc. Sylphs will often battle each other for fun; this will manifest as un-forecast and usually devastating storms.
It is virtually impossible to kill a sylph; there has been no sylph killing in recorded history.
