Wind

Wind is one of the three primary elemental forces of the world (fire and water being the other two). Wind can be felt, and its effects can be observed and measured, but wind itself cannot be seen. It is an invisible force that assists in weather change, and provides power to machines that take advantage of it.

There are many myths and stories behind the power of wind; it seemingly comes from nowhere and is recognized. Polytheism religions often attributed the power of wind to a deity, or a servant.
