Ok, I understand it now. What you are asking for is an Order essentially, that oversees more than just the individual holy site attributed to it in order to be formed. What I see here is that you are searching for the word, diocese. That is a possibility. The real possibility also after such is that the evader could rebel and you would get a schism and lose that chunk of your church body. But it is a worthy discussion, I think.
Yes, that is the word I was missing. Thank you. It was an attempt to admistratively subfeudinate rather than using territories as the basis.
You are correct that the main problem is schism but then again in Yagnar as in Tarot and Urda there is a large leeway for differences without the need for 'breaks'. Illuvarians may also have that same leeway technically but I don't know if that would play out IC.
