Sidebar discussion involving the Twilight People / "Zath":
What's the difference between "I can't shaft this guy because it's wrong and also others will find out and not trust me any more"... and "social trust"?
Distant colonies?
The last time they went out in the broader world and tried to set up in far away locations, the war happened. They're OK with the Choumin (who are dedicated to their Storm God) , and the humans in their own territory (who are largely refugees from past religious strife elsewhere and want nothing to do with zealots and "jihads"), and some others, but anywhere else there's too much chance of some local sun cult flaring up in outrage or some other nonsense happening.
And they don't have the numbers, and their culture doesn't really support domination, and so on.
That looks a bit like one of my "I'll go back and finish that thought later" moments.
The child is surrounded by adults who are all within the general scope of the culture, some of them who've been part of making that culture for a very long time, not to mention sharing the same core "Zathness" in the same way most humans share a certain core "humanness". I guess it hadn't occurred to me that there'd be much drift or differentiation.
To start with, it's not about power... typically a "Zath" in a position we'd call "leadership" views it as a responsibility, not an opportunity to exercise power. Telling others what to do is viewed as more of a burden than an opportunity. And others aren't looking to figure out where they "fit" in terms of power, they're looking for a "leader" who knows what they're doing, and mutual respect.
Honestly, I just do not understand the appeal of or need for religion, faith, belief, etc -- or what other people get out of ceremony and ritual -- and in part I wanted at least one "species" in one of my fantasy settings that I didn't need to "fake up" a belief system for. And given that they're a very empirical people in a low context culture, and that they know exactly how they came to be, and that their "gods" are dead... I just don't see why they'd have any use for religion or the related branches of philosophy.
To begin with, when someone wants to justify getting their nose in someone else's affair's the first thing that others are going to ask is, "How does this effect you?" or "What do you stand to lose or gain here?" If there's no tangible impact, no actual connection, that can be pointed to, then the nose-sticker isn't going to get anywhere.
Painting the inside of their house some "odd" color isn't anyone else's business. Putting up a ramshackle awning that might fall onto the road and hit a passerby is. Dumping something in the river that might hurt people downstream is other people's business, particularly everyone downstream. Who they "spend their evenings with" isn't anyone's business unless one or both parties is violating an oath made to a third party, in which case it's that third party's business. Etc.
Technically, the Sun People are dead, it's just that there are quite a few human followers of the sun deity who took the place of the two creators in the pantheon, especially in the Rasenna Republic, etc.
The Silurian map wasn't ever more than an illustration of the general idea for the size and scope of the Choumin-controlled island chain.
The Choumin aren't sun-worshipers, beyond recognizing him as part of their pantheon, they're called the Storm People for a reason. And there are other cultures where the sun deity is just one of many.
It's not that they're depending on outsiders for food, it's that they have a very wide range of tastes because of all the trade that passes by, goes through the "dark cities", etc.
The baker is probably doing it for the love of the craft, because they're good at it, because they make a good living at it, etc.
There are people in the real world who do things like recover old log-built cabins and barns, and use the timbers to build new houses using a lot of the old original techniques. It's hard and sometimes dangerous work, but they do it because they want to save that history, and they love working with those old giant timbers, and so on.
This doesn't necessarily explain the guy on the ropes or the chimney sweep, but I'm picturing them as having some mechanical aids that make their jobs a lot less risky and a lot less grinding.
As I noted in the previous post, I've been debating something like the "shadow helpers" idea you suggested for a long time. There would probably be multiple tiers, with the really dangerous work being done by mindless drones, and then some other things done by something a touch closer to Eberon's mechanical people (warforged?), but more with a more clockwork/alchemy vibe.
