Baba-Yaga, also called Baba-jaga, in Russian folklore is a supernatural being (or one of a trio of sisters of the same name) who appears as a deformed or ferocious-looking old woman. She is wise and powerful; wild, cruel but sometimes also kind. Baba Yaga makes a link between the wise women of early myths and the witches of the folk or fairytales
She lives in a forest hut which spins continually on birds’ legs; her fence is topped with human skulls. Baba-Yaga can ride through the air—in an iron kettle or in a mortar that she drives with a pestle—creating tempests as she goes.
