Just thought of something. Xern humans came from Exendrian humans, like most humans as they spread throughout the Galaxy. They both have x in the name, so perhaps they like to include x in a lot of planet names and maybe names from royal families. X at the last of the name is more low class and no x is for people furthest away from exendrian culture as the formed their own governments. Not all exendrians still keep this tradition as a lot of human groups intermingle, but with royalty more pure in blood and tradition, it's more kept. Ahsuda humans diverged greatly from them so dropped the x. Maybe the group that became ahsuda were Axuda.

Most exendrians are dark skinned but I think I said on the wiki only 60% or something. It's the golden eye trait that's much more universal among them. Xern humans lost this in addition to many other groups.

I'll draw certain races first if you guys really want to see how a race looks in a picture. Humanoid ones are easier since I already drew a human that I can alter. However, some aliens might be more fun to draw if they aren't as humanoid. Guess I should draw a male human too, if I can get around to it.
