I have a proposal for you Khan. My city-state has religious freedom. So i'm guessing that there will already be quite some religions present. So you're very welcome to have your Healing Church their too. However, actual religious buildings are prohibited within the single city I'll have. This is because the city is inherently built by the followers of the Old Ways, who's religious 'building' is within the nearby woods. Though Justianism is starting to be introduced there, mostly within the slums just outside the city walls. If you'd like, your Healing Church could be there too. As I assume that a church focused on healing would have field day in the slums. What do you think?

((PS: My location is far west, on the southern side of the spine. It's the first city state you meet if you want to enter the isthmus from the south. From Tityos' side.))
