Chang Er

In ancient China, Chang Er was the wife of the archer Hou Yi, who received the herb of immortality from the gods after shooting down nine of the ten suns that were stifling the world with their heat. She consumed the herb and ascended to the moon, where she still lives in the Palace of the Far Reaching Cold, accompanied by her maids, two children, and a hare which grinds cinnamon tree bark, which confers immortality.
