Well, they have three ring cities in RifE, so I didn't mention it. Can't speak for Sephi, so didn't bother. I like my interpretation of the Doviello, but no reason Sephi can't do that. RifE has it's plans for a one-ring civ. Two of them, actually. We only have.... 6 civs on the drawing board, all very different. Plus the 4 or so that are being developed as modmods by non-team members, which may or may not make it in eventually.
