User with this ability either is or can transform into an Glaistig (gaelic lit. water imp), a solitary supernatural being of the Scottish Highlands, with the upper half of a woman and the lower half of a goat, although she was also believed to appear as beautiful female, a goat-like hag or a small woman dressed in green. She has pale (often grey) skin, long golden hair and like many of the fairy races she often dressed in green, long flowing robe, which covered her goat half.
