The thing is it's much easier to go from has control of your world body to make a Gaol then to try and go from Gaol to getting control of your world body.
I'll have to think about it very seriously. I am on the fence about it. I see three paths, if I was to revise the setting (for what is almost certainly going to be the final draft):
1) Keep everything as is. Pros are: we get gaols immediately and backed by charm power
2) Expand the size to Vast. I probably won't expand the size of the cities and the equatorial belt linearly, because at a thousand kilometers wide stretch you don't really have "pockets of safety" anymore, even if it ranges from deep arctic (but Earth-like arctic) at the edges to probably jungles at the center, but I'll have to think about it. Pros are: infinite population, the setting (in amount of people, and, thus, the story potential within) becomes bigger than Earth, we most likely start to significantly outnumber Winter and other factions
3) Get Lord of the Land. Pros are: narrativey awesome, cementing Molly as the god of the realm, signature charm boost. Also probably some story potential for how Molly explores the feelings of her World Body, because this probably comes with some sensory feedback.
In all times, I am keeping the Malfeas-inspired under-ice Great Prison, but the state of its functionality would differ, obviously.
I'll think hard about it, and I would very much appreciate opinions from other questers. Ultimately this is being made for you.
