That's something to consider. Thanks for the input.

Here's a couple of images that could help showcase the kind of style I am going for with the cultures.

Also, I made this basic graph to show who is sharing borders with whom. Gets a bit cluttered in the North, with both Vandren, Dusk Elves, and Forest Kaas being no cohesive groups and often overlapping with the other tribes, but I think it gets you a basic image of what people might come into somewhat regular contact with each other.
