my favorite thing about the temeraire series is that in the fiction, dragons always existed and were in interaction with people throughout history. outside of england (which is mostly unaffected for the purposes of story framing), the development of civilizations was affected by their presence. there were dragon philosophers and poets, industrialists and explorers.
if you want to have high fantasy and a technological/industrialized society in the same story, fuckin own it. play it out, see what happens!
