Yeah, I think we would need settlements before we have agriculture. And I don't think I will have Regulus create a sentient species. He might create a legendary beast/s that are sentient, or later become sentient. At least for the time being. 

Right now, he is probably going to take what humans there are right now and organize some of them into an Order of Druids. If not this turn, next turn. 

I am thinking about having him create a rolling plains for humans to settle on, but that isn't going to be important until we start settlements. So I may save that last point of might, or use it to buff my druids.
