This is all good and well. Under the circumstances I don't expect the Spanish Inquisition (see what I did there . However... How long does it take for these two statements to get confused?
- The blood mist means everyone must stay in their place.
- The blood mist means everyone must know their place.
As societies contract and become less fluid, I'd expect those in power to face a choice between democratization/liberalization or sharply increased authoritative measures (or think up some entirely different way to keep regular people submissive). E.g. the late stages of the Roman empire set the scene for the medieval feudalism by stripping citizens' right to migrate, taxing in kind instead of in money, and working intensely to develop a fitting religious scripture. A small setting would put different requirements on legitimization of power structures but it seems that theology would still play an instrumental role.
I'm not advocating a rethink, especially not since I haven't even seen the actual material. I do want the door kept open for some really grueling interpretations that are complicated enough to interest my players.
E.g. one of the interpretations I have in mind is that the mist was really really good for those in power and that they now collectively face a common problem that invites them to cooperate to fight back against the tide of liberty of movement that is sweeping over the land.
Klas: You hit the nail's head here more than you know. Once you read the material you'll understand why your bulleted confusion also has confused the inhabitants of Ravenland for a long time.
Concerning the power struggle, what you say is all valid. In fact the confusion and struggle for power you describe is a big driving force in the Raven's Purge campaign. What I find especially interesting though is that this struggle is happening ”whilst we play” and not at all is settled.
Concerning the Blood mist actually being useful and desirable, that is precisely the situation for the Rust congregation as you will see, especially in the ”Haggler's House” adventure site.
