Well, you can show what you have. Another quite important thing, our kingdoms would have known eachother for some time, unlike WAL. So they prob hav some history. You guys can briefly give a first look on your kingdom so we can then decide what's what.
My kingdom is going to be a diarcy(2 kings) where the power is spread equally between the royal cousins/brothers. One of them is the leader of the templars(anti mage army, not going to call them templars but whatever) and the other controls the main army. One controls culture and religion the other controls research and economy, etc etc
In the end My kingdom would be preety basic except they hate mages.
