King of the River Valley is 16th level, btw, as a Barbarian 6/Fighter 10.

Also, yay, Dragon King made the cut, though listed with the human kings. I suppose that it's divided by race of primary subjects.

Also, I thought that Druids were out for Oracles? There's a lot of Druids listed...

Also, we need a straight up Rogue King. Think Jaraxle and the Bregan D'aerthe, one who maintains power by keeping information on his rivals and playing off of them to maintain his small but independent clan a force to be reckoned with. It's not all about sheer power, it's about how you apply it, right?
