Baba Yaga

A wild witch of the forest, often depicted as an old crone who flies in a mortar (grinding bowl) and lives in a hut that stands on chicken legs. Baba Yaga can be frightening and does eat the unwary, but she is also wise. She tests heroes and sometimes gives aid if treated respectfully. Her house spins and screeches and is guarded by a fence of glowing skulls.
