Just so I am clear on this one thing. The Khargats came down from the mountains, right? So that means that my Belintashians were the first "southerners" they came across and fought with, I would assume.

I take it that Belintash doesn't extend across the entire northern side of the empire and the entire mountain range (because that'd make your province pretty huge) so I didn't specifically state that they came into contact with Belintash first. The first people that they came into contact with were conquered rapidly and essentially wiped off the map. Whether that would be some other state(s) further along the mountains or a former part of Belintash can be decided by you, but note that many of the Khargats remain in that hilly territory that they first conquered. While various groups move around because those foothills can't sustain all the nomads and their herds indefinitely, that land is sort of their stronghold and where they'd fall back to if they were pushed out of other regions.

So ultimately it makes sense to say that the Khargats came down and sacked a bunch of your cities and stole your land (and furthermore, that many of them remain on that conquered land in the modern day!) but I left it intentionally vague so as to not force that history upon you. But if you're fine with it, then that's cool and I can edit my sheet to be more specific regarding that initial invasion of the south.
