undine

The asrai and the undines had slipped into the icy northern sea to head south for the mouth of the Kell, where they would swim upstream to their cool lakes and rocky rivers.

Undine, un-dēn′, n. a spirit of the waters, a water-nymph, without a soul—they marry readily with men, and an undine herself receives a soul on bearing a child.

In like manner exist the undines in water, sylphs in air, and salamanders in fire.

Hence it was the constant endeavour of the female spirits to captivate the admiration of men, and of the male gnomes, sylphs, salamanders, and undines to be beloved by a woman.

Occultists, from Paracelsus to Elephas Levi, divide the nature spirits into gnomes, sylphs, salamanders, undines; or earth, air, fire, and water spirits.
