To further add to the fundamentals: The fundamental virtues of the church are humility, temperance, generosity, compassion, and order. The fundamental beliefs is that while magic exists, it exists to serve mortals so that they may more effectively bring back order to the chaotic world. The Serene One is the only true creator and way back to paradise, and the primordials are the bringers of chaos and sin. 



EDIT: This is just the outline really, it will be up to the players roleplaying the high council to doctor in the actual rules and laws to be ministered, as well as the history of the church and detailed structures and locations.
