What happens if Avatar: Fire and Ash doesn’t make enough profit to convince Disney to bankroll Avatar 4 and 5? Creator James Cameron has said he’s ready to walk away from the franchise, adding he’ll write a book to resolve the one thread Avatar 3 leaves open.
If they do make it, then they get to feature the not airbenders for Avatar 4.
And then the Not Avatar will come to save the world in Avatar 5.
You don’t think the ‘not-airbenders’ were the ones who lived in trees on floating mountains and rode giant flying things?
IMO it’s the cave-dwelling Na’vi we’re still missing.
I would have said desert or savannah/steppe
Eh, most of the Earth Kingdom lived on open mountains and cities.
Do the humans count?
Bonus points if the Na’vi inhabit it in Avatar 4. And call it Na Sing Se.
