I'd suggest not having too many Xyrican-like cultures lying around, they're probably the most exploitable of the cultures overall. You know, the kind that some pirates will look at and take over to get lizards to use for raids. I'm not 100% sure where you put your natives, but I wanna put mine on that isolated continent far away from all the other ones, Uarsh I think it's called. Ruious looks nice too [but it's a bit close]. Believe me, they're not pleasant and human activity has made them more active than they normally were due to their machinery and technology shaking the ground too much and causing a few too many caves to unwittingly collapse. Just a hint of the kind of folk they are. Choices choices.
