Korean mythology and folklore is full of gods, goddesses, and deities, drawn from the rich heritage of the primary belief systems. Known as "Shin," which means deity or spirit, they are supernatural beings endowed with the power to influence the human world. Shins are served by female shamans known as Mudang, especially during Gut or sacred rituals. Each god is given responsibility for a special area, although these vary depending on which version of the myth is being told.
