Basically my plan is to visit the combes now, visit Uzkulak on the way back to K8P and scout it out, then spend a turn preparing: learning all we can about religious doctrine, Ranaldism, buying useful books, and getting in touch with Ranaldites around the Empire. Between our friend who helped us melt down that statue, the Empress, and maybe the Gray College, I'm sure we can come into contact with someone who could manage a spy network/resistance/religious organization.
Then we finally head to Uzkulak, work with our new friend to get things established, maybe spend an action on the following 1-2 turns as well to do work there, and then our new friend will continue managing this little subversive organization while also being our contact within Uzkulak. We can go to them for information on the goings on in Uzkulak, and they can do things like request supplies from us when needed.
...Also, on Panoramia's hair, I personally thought of it as green. But I can totally see browns and reds and such working too. Earthy colors, indeed.
