Your examples there would both be fine by me. Regarding "technically all their tech doesn't violate known physics," I think it's cool when some sort of reasonable-sounding explanation can be given for how an artifact or technology works. That said, I'm willing to handwave it and just let the workings of some let some things be left vague or entirely unexplained, for the purpose of allowing things that make the story interesting.

The only thing I really don't want to see is blatant magic along the lines of the psykers from 40K or the Force from Star Wars. Just to be clear, technologies that can somehow fry brains or enable something resemblant of telekinesis would be fine, so it's not the powers there that I would object to so much as how the existence of actual magic goes against the setting's big theme of charlatans using sci-fi devices to fake magic and divinity.

But I think we're mostly along the same wavelength here. Feel free to join the Discord that I linked at the bottom of the OP!
