About Kings, AFAIK years before there was only Calradic Empire, then it starts losing territories to the rebels and other outsiders, then Empire's itself started to divide into West, East, South etc.
This means, there should be one old, weak, incompetent, sad King, a King which was a whole united Calradic Empire's King, but couldn't fix problems and lost nearly everything. I don't know which Empire faction's King (South/West/East) was the King of whole Calradic Empire at the beginning, lets assume it was Western Empire's King. That King should be seen so old and weak, and incompetent, also his lords wouldn't trust him much. If that king stays at his Castle all the time, and always sits in his throne like that;
and when we talk with him, he was always like hopeless about the future, it could be very good and kindly realistic. He lost most of his empire, he couldn't stop civil wars, he maybe lost his family, his lords hate him, at war with multiple factions etc. so he is in desperate position.
I mean, in Bannerlord, that King should not be drawn as "strong, smart, trustworthy" king. Right?
