The Weaver is also known as the Celestrial Weaver. This primal diety took chaos and spun time, space, fire, earth, air, water, light, and spirit into existance. He then wove these things into the world, choosing things for their artistic quality.
Sure there are other spirits, he made them. Some of them claim to be Gods, but they are just powerful spirits.
Priests of the Weaver are embedded into society. There is one priest in every endevor, company, or village. They are advisors who help “those who do” follow the correct pattern, as set down by the Weaver. There are five ranks of priests who report to and are advised by the rank above them. Every rank is assigned a more important group, with only the top most weaver priests doing nothing but advising lesser priests and kings. This way the vision of the Weaver can be maintained, society and event continues on as if they are supposed to.
Not following the Weaver’s pattern leads to chaos (or unluck). If you are not in your right place at the right time you will be cut from the cloth of the world. It fear of being removed that keeps people following the general advice of the Weaver Priesthood.
The reward for following your “pattern” is that your pattern will be re-used time and time again… a reincarnation of sorts.
The Weaver’s priesthood is astrologically inclined. The stars are the language that The Weaver communicates his ideas for the pattern.
