huldra
The huldra is a mythical creature from Scandinavian folklore, often depicted as a beautiful woman with a cow's tail. She is known to inhabit forests and mountains, luring men with her enchanting beauty and singing. While she can be friendly, she is also associated with danger, as those who fall for her charm may become lost or enchanted.
In some tales, the huldra is said to be a guardian of nature, protecting animals and the environment. She is often portrayed as a symbol of the wild and untamed aspects of nature, embodying both its allure and its potential peril.
