The Church of Humanity 'lost' in that they lost three regions with temples, but the temples are staying, so it's more of a draw.
...what three regions? If you mean Azros's duchy, only Azros itself had a CoH temple. The other is an Order of the Elders temple.
Where did that happen? Not to say it didnt happen ( I know the CoH isnt at all fond of Sartan or your Ibladeshi newcomers in general), I just cant remember it.
My Zonosan character burned a few shrines and torched a temple. Cathay should thank him for weakening the Sartanist control even by a little bit! Sadly, they just reappoint Sartanist lords. Well, when they're absorbed and turned into a theocracy, I guess they'll learn.
