Hmm, I see what you're saying, but no, I think it's fine to mix countries for the knights. I would think that, on the part of the school, it may be a measure of building relationships between countries in their case? Mostly just trying to avoid backing ourselves into a hole regarding the pairing and what we can and can't do with it.

It could be hilarious if the school pairs countries that feud with noble and knights in hope to make those countries have a little more positive connection in the future.
