Wait, what? That sounds like a meta-gamey and a very dirtbaggish move.
If you think he was invited and then told by JPierreD afterwards about that I would agree a little but I tell you what happened to clear it up. JPierreD invited someone, either to the game or just to Morek. They joined and went to Morek, a theocracy of SA. They asked for a estate, and were told by either the lord or the message group of lords that you must join the church to have in estate in Morek, a theocracy. My point I am making it does make sense IG that a theocracy have you join their religion before allowing you to have an estate their.
