Why link a priest, or even religion, so hard to a realm? If by anything, the medieval system did not work through a centralized state. The concepts of realms as we have it in Battlemaster, be it intended or not, is not at all accurate.
Link it to the lord. Recreate the feudal system. Get rid of "states", it's completely un-medieval. If the priest RTOs a region, the region should join the duchy of his lord. Next to that, it is not the religion that should be subjected to a state, but the other way around.
To add to Peri's post: yes, I am the ruler of Ibladesh but my character (and that's how I play him too) is first of all the High Priest of the Church. The State is completely subjected to the religion and is but a mere tool of the Church. We have strict rules about religion in Ibladesh. Not a good or interested follower? No promotions in the mundane world whatsoever for you! That, and we are on our epic quest to conquer and possibly convert all of EC!
