In Slavic folklore, Baba Yaga is a supernatural being (or one of a trio of sisters of the same name) who appears as a deformed and/or ferocious-looking witch. Baba Yaga flies around in a mortar, wields a pestle, and dwells deep in the forest in a hut usually described as standing on chicken legs (or sometimes a single chicken leg). Baba Yaga may help or hinder those that encounter or seek her out. She sometimes plays a maternal role, and also has associations with forest wildlife.
Błędnice (en. stray) in Slavic myths usually dwelled woods. Mischievous and mean, lead wanderers into the wilderness, tangling their paths and not letting find the right one. They usually appeared when least expected – for example when there was a simple way to go.
