My WIP takes place in a world away from Earth, but that does hold a shared history with Earth. There will be a commonality of language and sociolinguistic heritage. The words of Old Earth are still with them, to include even remnant words referring to high technological, though that technology may no longer be present, or exists but in profoundly different ways. This heritage is only ever hinted at (through remnant words) and becomes central only towards the latter half of the story. There are families of power, but these families answer to more of a post Edwardian, industrialist, capitalist, monied kind of power and they style themselves 'lord' and 'lady'. Those who hold these titles in the present timeline of the story are the children of the first to ever style themselves with such titles in this setting, in this world. Is it plausible that a society on the brink of industrializing (think somewhere between the Age of Discovery and the Industrial Revolution) would accept and defer to such a strata of society without there having been a prior (or present) age of monarchic rule with all the trappings and derivative titles and powers flowing away from the king's castle and down into the local land gentry?
