Mayago
Mayago is the main character in the Korean indigenous legend about the goddess of Mount Jiri ( Jirisan). Her status is as a mountain goddess, who is in charge of taking care of a particular mountain to which she is assigned to. Mountain god(dess)s are one of the main deity a Mudang or a priest(ess) who prayed to for good luck and harvests. Sometimes such priest(ess)s lived on the mountain, usually the higher the better as the height of the mountain determines how close one is to heaven and the gods who reside there.
