The Duchies of Estalon
The faiths of the land can grant devout followers clerical investment, which allows the clergy to perform miracles and cast certain spells in the form of prayers. The strength of clerical magic is determined by the sanctity of the area where the clerical magic is used. Places holy to the faith grant enhanced results, and seats of opposing faiths making it nearly impossible to use clerical magic. The magical effects are channeled through prayers and rituals handed down through the faiths.
Relics of faiths can also have potent effects, raising the local sanctity of the area, or granting the wielder powers similar to those in the gospels and stories surrounding it.
