>A hulder is a stunningly beautiful naked woman with long hair, and has an animal's tail. In Norway, she has a cow's tail, and in Sweden she may have that of a cow or a fox. Further in the north of Sweden, the tail can be entirely omitted in favor of her hollow or bark-covered back.
>In Norwegian folklore, she is known as huldra. She is known as the skogsrå "forest spirit" or Tallemaja "pine tree Mary" in Swedish folklore, and ulda in Sámi folklore.
>The hulder/skogsrå appears in the form of a small, beautiful woman with a seemingly friendly temperament. However, those who are enticed into following her into the forest are never seen again.
>It was said that any human man who has intercourse with a hulder/Skogsrå becomes an introvert - his soul has remained with her. If the seduced man is a hunter, he may be rewarded with good luck in the hunt, but should he be unfaithful to the hulder/skogsrå, he will be punished with numerous accidents. He may put an end to a stormy night caused by her vengeance by firing a shot against her.
>The hulder has long been associated with hunting; she might blow down the barrel of a huntsman's rifle, causing it never thereafter to miss a shot.
So we have a qt Nordic forest nymph with
a fluffy cow or fox tail, hollow treelike backpussy, who seduces men and blesses them for their virtues with luck in hunting.
Excuse the shitty art, it's all I could find from searching.
