The Nixies, Undines, and Stromkarls were particularly gentle and lovable beings, and were very anxious to obtain repeated assurances of their ultimate salvation.
The Neckan
J. P. Molin
Many stories are told of priests or children meeting them playing by a stream, and taunting them with future damnation, which threat never failed to turn the joyful music into pitiful wails. Often priest or children, discovering their mistake, and touched by the agony of their victims, would hasten back to the stream and assure the green-toothed water sprites of future redemption, when they invariably resumed their happy strains.
“Know you the Nixies, gay and fair?
Their eyes are black, and green their hair—
They lurk in sedgy shores.”
Mathisson.
