Which, again, is perfectly fine and understandable. Tension in the setting this way is a fantastic idea. Lots of stuff to mine from that sort of thing.
But, the fact that you have "Little Tabaxiland" pretty much means that there are enough of a given population within that area to actually give rise to a "neighbourhood".
What I find really funny about all this is that 99% of the time when people talk about wanting half a dozen or so PC races in the setting, it's pretty much always the Tolkien races - and they live together in more or less no problems because .... reasons. But, for some reason, the notion that half a dozen races can co-exist but a couple of dozen somehow becomes unbelievable.
Just because there are 60 (ish) PC races in 5e does not mean that you will actually see them in a given campaign. This bizarre notion of top down setting creation where you must define the entire world before play starts is just weird. Every single published setting has added races after the initial publication. Every ... single ... one. Yet, apparently, I guess that means that every single published setting is totally unbelievable and unrealistic?
Good grief, even the notion of geography doesn't really apply. You have numerous races with planar ties. Fey or whatever. Never minding the underground races as well. The amount of "livable" land in a D&D world is VASTLY larger than the real world.
