"Baba Yaga (Russian: Ба�?ба-Яга�?), is, in Slavic folklore, the wild old woman; the witch; and mistress of magic. She is also seen as a forest spirit, leading hosts of spirits. In Russian tales, Baba Yaga is portrayed as a hag who flies through the air in a mortar, using the pestle as a rudder and sweeping away the tracks behind her with a broom made out of silver birch. She lives in a log cabin that moves around on a pair of dancing chicken legs, and/or surrounded by a palisade with a skull on each pole." _Wikipedia
Reverred as one of the dark or crone goddesses in some traditions of modern Wicca.
