No? This is a bunch of Tolkien tropes + Conan the Barbarian + a bunch of shuffled around real world cultures.
The Last Airbender continent was mostly China, with the fire nation being steampunk imperial Japan. At the poles there were the Inuit-inspired water benders and the Air Benders were Tibetan monks except spread around all over the place on mountaintops.
There weren't any Egyptian pyramids or nomadic steppe peoples that I can remember being portrayed in Avatar, and there certainly weren't any elves, orcs, dwarves, wizards, or barbarians from the icy north.
I like how "Norway" and "Japan" are still clearly visible... Is this the world but based? No America, barely any Europe, Africa no larger than it needs to be...
