Wouldn't a massive missionary campaign organized by the Church to a specific area of the continent, like the southwest, be pretty interesting? Since SA will not likely ever have the ability (at least for a long time) to actually ever invade a place like the southwest and force their religion, what if they went the peaceful route (shock, I know, it's SA) and just did a massive, RP-heavy missionary campaign sending tons of missionaries to the area to convert Nobles and people alike?
They would likely meet a bunch of closed borders and "no preaching without formal permission" restrictions while being met with cold silence. In other words, encouraged to pack their stuff and go back from whence they came.
That's what I'd expect of it, at least.
