>>84635It's not a fantasy world, but it doesn't use real world nation names. It's just a generic setting for a plot about nobles and princes doing romance shit as far as I can tell. I also think it's just a sketch of Europe from memory by someone who took geography in school 20 years ago and isn't meant to be consistent because the next cut show Britain magically back in place and also Catalonia is a land bridge to Sardinia and Anatolia is a huge lake. Oh, and it's clearly Victorian-era but the borders are modern(-ish).
It's a real shame the show isn't going to delve into this at all because I find that map way more interesting than anything else it did.
