A nix is a German water-fairy in human form that wears a green hat and has green teeth, the female (nixie or nixe) is in the form of a beautiful woman. They live under lakes, rivers, and ponds where they have wonderful cities and beautiful houses filled with riches.
Though often described as human-shaped they are shapeshifters and can assume any form. When the females come ashore they appear as normal human women, only smaller. They wear the same type of clothing that other women wear except that their hem is always wet. They have slit ears, and unusual looking feet which they will attempt to keep from view.
They may also appear as a fish or as a human being with a fish's tail, like a mermaid.
Those who make offerings to the nixen during a drought are rewarded with rain, they also cause storms when offended.
Magical sheep and cows live with them below the surface, sometimes they allow their animals to go on land to mate with the human's animals which results in an abundance of offspring.
They love singing and dancing. They come on shore to dance with humans and they dance underwater, sometimes you can hear their music coming from beneath the waves.
They also use their music to lure people into the water so that they can kill them. Each year they claim one human life, anyone who interferes becomes their next victim.
If you see them dancing across the surface of the water it means death by drowning is coming soon.
The females offer assistance to women in labor, they also steal children and replace them with changelings, the males kidnap human women.
They cannot tolerate salt mixed with their food, and they can foretell the future.
Also known as nixie or nixe (female), and nixy.
