Questions on Sauromatae gameplay

[Liberator]

"Indigenous Settlements" are the same thing as "Military Occupation" for other factions. Which means you can and should build them always and everywhere (+5% law bonus for 200 mnai is spectacularly efficient and you'll need it anyway). They even come with a prettier symbol than the "Military Occupation" of other factions. You'll need to destroy all previous foreign government structures though (Types I-IV, Nomadism, Pastoralism or whatever else).

Well, I have figured that out so far while conquering the Caucasus.
But still - I found no way to build a client state in the two Crimean provinces, for instance. Only normadism and pastoralism available there for me while the recruitment viewer tells me that I could recruit Greek Classical Hoplites there, for instance.
