Your writing is very clean and easy to read, which is a real pleasure. I find myself recommending often that writers add a section at the beginning to clarify "what's really going on" but that urge didn't come up while I was reading your - I think because it's pretty straightforward from reading the descriptions, particularly A22. I love the twist on the classic "you start as prisoners" scenario, and the story of the divine/mundane are rad as hell.
Great job it was a lovely read!
