Idk wtf is going on with some of the "Defender"-tagged regions so feel free to insist that I delete some. I don't know your world like you do.
Also there's a cohort of vaguely-aligned "Pariah" regions with 200 - 300 total endos (I'd say maybe only ~150 of them are actually "organized" (such as they are) into a "sphere of influence") that I didn't even bother adding to this chart because that was sure to cause "problems" in this forum.
There are also some medium-sized regions
