The Philosophy of Heroes of Might and Magic.

It's clear with people - their society, as already mentioned, resembles human society (our medieval one).

Progressive Middle Ages. Neither in Erathia, nor in Harmondale, nor in Bracad, nor even in Nighon, are there inquisitorial bonfires, conservatism, or a denial of development and progress.

Sometimes, governance is based on feelings (Again, Catherine and her companions:))

Catherine??? Based on feelings? What makes you say that? You probably read the story "Catherine's Heart" on the Hugo Corner. This is not a reliable source, far from it. If Catherine's governance was based on feelings, she wouldn't have been able to properly rule Erathia for five years and win the war against Eofol. Yes, she loved her homeland and her father. But shouldn't every decent ruler do that?
