What program did you use to make the map? Very spiffy! Though I can't find Coriandel on it. (Maybe it's there, the print's a little small so I can't read it perfectly.)
Inconsistencies and questions... Well, I've already pointed out in the group discussion about Beneath Coriandel that the Darpani language-as-'translated'-into-English seems far too uniform, always with exactly the same verb structure--'to ___'--no matter what the gist of the sentence. Rather unnatural, as least as far as human languages go. And I have a note about the Aphsi to bring up tomorrow. Other than that, I think you've constructed a very believable world here. Nothing jumped out at me as I was reading various sections. A few things did occur to me thinking it over, though. Maybe some of it will be helpful:
-the focus of the Human Geography section seems to be on either cities or nomads, depending on the area. I'm seeing very little mention of village life, though in pre-industrial societies, that's usually where most of the population lives. How are the village people of, say, the Karaband governed? Are they under jurisdiction of one of the major cities? Do they self-govern? How do they relate to one another?
-speaking of cities and governing, it seems odd to me that there isn't more conflict between the various peoples, especially since their cultures in many cases are quite different. Why has no one ever tried to take over, say, the Darp? The Bantang peoples provide some threat, but otherwise (based on the stories I've read from this world, and the lack of mention of it in the summaries here) none of the peoples seems to worry about any of the other peoples infringing on their borders. If you look at most pre-industrial societies in our world--say, Europe, or China, or Northern Africa--the peoples were always trying to conquest, gain more land, conquer each other and rule over as much area as possible. Even within one country/culture, the lords/kings/cheiftains were frequently trying to wrest territory from each other. Why are the peoples of Cherne so relatively peaceful?
-on a similar note, it might also be useful to write out how each people views the other peoples in Cherne. Who do the Karabandi like better--the Darpani or the people of the Regimental Kingdoms? Why? Things like that. Important especially considering there seems to be quite a bit of interaction between the various peoples in the world.
-this was touched upon in the group, but I do think Cherne needs more religion. I can't think of a single culture on Earth that didn't have a god or gods. Religious beliefs seem to require it--because, I suppose, if there's reincarnation, who's organizing it? If things are a certain way, who made them that way? Consider that one paragraph after saying the people of Cherne have no gods, you mention the Darpani's belief about the Creators (and Creators are nothing if not gods, no?). I think they need them, and I think they know they need them. ;)
Hmm, seems like I came up with a lot after all. Probably some of that is answered in sections I missed. Anyway, hope it is thought-provoking, if nothing else.
