Curate, connect, and discover
I think Indigenous people could be brought from Earth to Pandora after the Na'vi learn about them. At first some of the Na'vi think they shouldn't bother. They are probably already poisoned by their fellow Sky people.
But when they sit and talk and show photos. They ask for more info and the research teams very guiltily give more. There's nothing but horror as they watch the same things happen to these people.
It's when they see the braids in several photos. And videos of their practices and holding each other as they do. They realize somehow they are all Eywa's people.
"Ma jake. Is this true? Do they suffer so much?"
He has to agree and hangs his head admitting he doesn't know much. He never had wanted to. He was a different person now and felt ashamed of his lack of care. More talk happens but deep down many of them know what they must do,
"Bring them here."
"What? You want more sky people??"
"No. We want Eywa's people."
When word reaches earth people are shocked. There was stories of the blue people told through TV. Suddenly the miners and military was sent back in shame. Years past and truth was learned slowly.
When the invitation was extended, people were scared. But a few agreed. About 50 at first. If it was Creator and Great Mothers will then they would go.
