Kinda... See, it was a large kingdom, but then the king left no will saying which of his sons gets the throne. So, in typical fantasy fashion, they had a huge war over it that basically destroyed society there. Now, criminals and merceneries live there to escape the law. There are some natives up towards the north.
I just realized I didnt label the rivers or ocean...
Edit: btw, iv seen lots of people with a little "river police" badge. How might I get one? i need to feed the ego.
