[@Guilty Spark] I was more looking at how domestication actually works with the number of years. with 40,000 years since the founding they would have 8,000 generations of animals to work with. Find the most docile one and start breeding them.

The other point I feel is valid, but coming from a background of D&D where prehistoric animals are actually a frequent monster I like using them. If I had the time I'd probably make original ones, but at the same time they'd likely be similar to these. I wanted a distinctly big and bulky animal for the wilds to use as their main cattle, and while looking through cryptid reports I was reminded of the wooly rhino. Considering the wilds are the northern most nation they'd have animals similar to this. I figured why not use them.

Also I'm starting to notice a big difference in how fantastic I've been seeing this world. I've been imagining magic to be at least semi frequent (the wilds likely having a solid number of druids throughout its history). Why can't that magic be used here? Need be I could go back to when mark is around and have a myth of him helping to tame the rhinos to feed the people when he isn't there.
