How are Auton social structures ? NuFrames were mentioned. Do they have schools and families ?
Autons don't really do families in the traditional sense: they're constructed with baseline enough information to function as robotic servants right off the assembly line with an extremely basic competency in whatever they were made for (as intended by the Watchmakers), meaning they don't require a social structure designed to perform that process while ensuring they reach adulthood.
However, there's ultimately an upper limit on how much info they can have pre-programmed, and while they don't have social and psychological adaptations related to child-rearing, they otherwise do learn pretty broadly similar to an organic brain, meaning things like education are still useful for increasing the population of AutoScientists, AutoEngineers, etc etc or if a NuFrame (which is basically slang for "freshly printed auton": they're the closest equivalent to auton childhood, though mentally they map closer to, like, older teenager almost out of high school in terms of emotional maturity and intelligence) wants to learn a skill they weren't preprogrammed for.
Was there any confusion about the Emperor being the Omnissiah or an embodiment of it when they were writing the Nova Testament?
What is the Warp/Magic phenomenon that is most appreciated/taken advantage of on Teklia?
Because the Nova Mechanicus and Testament don't require the political fiction that the Mechanicus and Ecclesiarchy worship the same god like the Imperium does to function, they don't really bother with it: the Omnissiah is the Omnissiah and the Emperor is the Emperor and so forth.
By and large the spiritheurgies used for making Muses, Bond Spirits, and so forth.
That's about what I figured for the Testament.
What are the most common ways the Huntmaster is represented? I know they're not realized yet, but I figure their worshipers have to have some images of them.
Crosshairs is their most common symbol attributed to them. Beyond that, the Huntstemples probably don't really like overt depictions: they'll probably utilize in art silloettes, only showing the Huntsmasters shadow, brief hints of his form hidden in the background, and so forth. It's not a full on Mohammed style thing where it's banned, but its probably taboo-ish, at least.
What are the Dreamlands like in mythology ? Can some NecroTek communicate with the dead ? Do our dead get eaten by demons or do they hang around.
The dreamlands are supposedly an infinite dimension unbound by the rules of time and space ruled by the gods, named so because it's where dreams originate from.
Seance Engines.
Why would I answer this?
What is the name of the regiment we fought on Yr Albain?
And since you're a fan of the House of Devils concept, I have to ask what is your opinion in genres that use such concepts like Hazbin Hotel, Helluva Boss and Chainsaw Man?
It's not super important so I'm gonna let that be one of those details left to omake authors.
I think the Hellaverse is neat, and I've heard nice things about chainsaw man but tbh I have trouble getting into most anime yeah.
Do any of our Devils sing or is it all strings and ivories with them?
Probably!
