Well, if it were me, I'd 100% have there be a race of sentient dinosaurs or dino-descendants.
I'm trying to steer clear of using primitive humanoids of any sort, actually. It's been done to death and it's not particularly looked upon kindly these days. I may have a pocket of technologically advanced descendants of the ancients living somewhere on the continent, though. I also do plan to incorporate giant lizards as riding mounts and, perhaps, flying dinosaurs.
For what it's worth, if it were me, I'd 100% have there be a race of sentient dinosaurs or dino-descendants.
Oh, heck yeah! I think I might know where my technologically advanced kobolds may come into play. Thanks!
