Baba Yaga from Slavic folklore (Baba - grandma, old woman)

Baba Yaga is an enigmatic or ambiguous character from Slavic folklore (or one of a trio of sisters of the same name) who has two opposite roles. In some motifs she is described as a repulsive or ferocious-looking old woman who fries and eats children, while in others she is a nice old woman, who helps out the hero. She is often associated with forest wildlife. Her distinctive traits are flying around in a wooden mortar, wielding a pestle, and dwelling deep in the forest in a hut standing on chicken legs
