What is nicneven?

Nicneven is a figure from Scottish folklore, often associated with witchcraft and the faerie realm. She is said to be the queen of the Hallowe'en, and her name derives from the Old Irish neimean, meaning "frenzy" or "fury". Nicneven is typically depicted as a tall, thin, and beautiful woman with long white hair and a green mantle. She is said to ride a white horse and carry a wand or staff. In some legends, she is associated with the Cailleach, a Scottish goddess of Winter and death. Nicneven is also thought to have influence over the weather and to be able to shape-shift into various animals. She is sometimes characterized as a malevolent force, but other times as a benevolent protector of the natural world and those who honor her.
