The amount of parallels you can draw between Hydaelyn and Eurasia is astounding, not just in culture or appearance, but in geographical location.
Kugane/Koshu <> Kyoto/Japan: Same appearance, similar cultural identity, same general geography.
Doma <> China: Similar appearance, similar cultural identity, same general geography.
Azim Steppe <> Mongolia: Do I even need to explain?
Thavnair <> India: Similar cultural identity, similar general geography.
Ilsabard <> Eastern Europe: Similar cultural identity, same general geography. Plus, I can draw comparisons to WWII :^)
Aldenard <> Western Europe: Same general geography, similar (by a stretch) cultural identity. Also feeds into eurocentrism.
Old Sharlayan <> Great Britain: Two nations that make colonies, hoard resources, and get isolationist when things go south? Say it aint so
Is this intentional? Maybe, but you aren't in the wrong for drawing the connection between Kugane and Kyoto.
