World of Wu-Yu
Wu-Yu is the goddess of the world. She is called the World Spirit, Mother of All, and Ancestor of All. She is a goddess of earth, agriculture, hunting, and the sea.
There is surely no more broad or nebulous deity than Wu-Yu. Thanks to the Doctrine of Unity, Wu-Yu has become associated with nearly every goddess in the world. Thus, her incarnations vary wildly according to local traditions. In one village she may be peaceful and nurturing, in another war-like and cannibalistic. What binds her many forms together is her feminine nature and associations with the earth.
The religion of Wu-Yun, itself a vast confusion of myriad local cults, holds her as primary deity. She is also the main deity of the Goblinoid religion of Yaj Yeeb, which knows her as the Giver of Madness and Ghost Rider.
