Sylphs

In the alchemical tradition and European folklore, air spirits, fairies with dragonfly wings.

The creature was first described by an alchemist Paracelsus as an Air elemental.

Appear and disappear with the speed of lightning. Sometimes they take on a human form, but for a short time, they also change their size, but they are not larger than a person, and often much smaller.

Sylphs, like other spirits of nature, for the most part treat a person kindly and harm him only when he annoys them.
