I'm sure someone, at least, has an Ichthyid province by now. It's not hard to get Rings of Water breathing and Shamblers, either. I don't think anyone's really devoted themselves to creating an empire based on the land yet(except perhaps Caelum and Kailasa, who are busy pre-tenderizing one another for whoever decides to eviscerate the winner). If one gathers enough provinces and Rings of Water Breathing, one could probably just spam enough commanders to take down an indy province(although that's a rather unorthodox method).
