Curate, connect, and discover
Thinking back to Republic City..... If it's a fusion of Earth Kingdom and Fire Nation Which represent China and Japan respectively.
Then maybe Republic City should represent a country that has both Chinese and Japanese influences. Maybe Korea or Hong Kong. Though I'm not sure if you could consider those countries a fusion a China and Japan.
Anyone from there have an opinion?
Personally, I think “Avatar: The Last Airbender” was better than “Legend of Korra” for one specific reason, which I hope you'll agree with.
ALTA was able to achieve its full potential Whereas Korra never got that chance. (Do you agree or disagree. Post your thoughts below.)
