Glaistig

The glaistig /ˈɡlæʃtɪɡ/ is a ghost from Scottish mythology, a type of fuath. It is also known as maighdean uaine (Green Maiden), and may appear as a woman of beauty or monstrous mien, as a half-woman and half-goat similar to a faun or satyr, or in the shape of a goat. The lower goat half of her hybrid form is usually disguised by a long, flowing green robe or dress, and the woman often appears grey with long yellow hair.
