Ah. I was wondering how the Dark Lord's dominion over the region currently occupied by the Yi would look like. Could it be possible that the Dark Lord settled for corrupting whichever dynastic ruler was in power at the time into doing its bidding (think LOTR Nazgûl, my bad if it happens that you're not familiar with the example I used), resulting in a not very overt rule?
Edit: I began writing a factbook; for now this is the link.
