Xi Wangmu (Queen Mother of the West) or Seioubo in Japan, is an ancient Chinese goddess, also known in Japan and Korea. She had a human form with a leopard's tail, tiger's teeth, and wore a jade tiara. She had three azure birds in her charge that tended to her needs by bringing her food and nourishment. In early Chinese mythology, she was the goddess of diseases, calamities, and slaughter. She would later gain immortality and enlightenment through cultivating the Dao and became one of the highest dieties worshipped in the Taoist pantheon. She took her throne on Mount Kunlun and became the the goddess of immortality guarding the Taozi (Peaches of Immortality).
Numerous rulers throughout China have legends and folklore attributed to them on how they went to her hoping to learn the secrets of immortality only to fail in the end. The most famous of which is King Mu of the Zhou Dynasty, whom she took in as a pupil and lover for a short period of time, but like all the others King Mu was unable to gain immortality. She would reach the height of her popularity during the Tang Dynasty where numerous cults centered around her sprung up and she became the subject of many literary works.
