So we recently discussed Yves and its conqueror/warmongerer specialisation. Which thus far give realm wide bonuses to exp for slaying enemies and bonuses to fighting rank. With a thousand years of wars and uprisings, my guess is the Yvesians are very advance here. They have another four specialisations as a level 5 kingdom. I'd bet they have Adventurer as well. Armorer, fighter and explorer would mix well with the first two picks, giving starting bonuses to attack/defense (10% for forged weapons/ armor), increased martial training speed and strengthened affinities and increased movement speed for everyone, as well as finding more useful locations for adventuring and a decreased chance of random monster attacks. If they were all at level 5+ that would be a crazy advantage. After a thousand years they could be level 10+ without it being unrealistic.
