plays after the events of the 3rd movie
The Sully family had one dead child. Neteyam passed away saving his siblings from the Sky people. Getting shot in the chest and dying in his family's arms. That's something people knew. Neteyam was rested in the Metkayina bury place. And that's when people last saw his physical form
Fast forward to after the Sully family had defeated Quaritch and Varang
Kiri and Spider are together, as spider is now able to breathe the air on Pandora and even has a Kuru. Lo'ak and Tsyireya are also together, Tuk found friends, Jake and Neytiri are still happy together
It was almost daily that the Sully family connected to the Metkayina spirit tree to talk to Neteyam, as his spirit is still with them. But lately, they weren't able to. Neteyam just wasn't there
That concerned them, of course, so they talked to some other people. Spirit tree and normally. Nobody had a clue, nobody except one. Grace.
Grace had a theory that maybe, Eywa has given Neteyam a second chance at living, that maybe somewhere, he is alive again. And then to that, she also said the clans on the Arctic part are somehow closer to Eywa than normal Navi and that there are stories about how they brought people back to life
50/50 percent sure, the family made its way there, one; to hopefully find Neteyam in his Navi form, alive and well, and two; Get Kiri to people she can relate to, as she now found out she's Eywa's child, it might be useful
the Journey was long, days on their Ikrans, from the warm Beaches of the Ometikayan Clans. Way down to the Ice beaches of the unknown ice clans. First, the temperature and sight was fine, colder than usual. But as they continued searching, it slowly got harsher. Snow falling made it hard to see. Cold wind making all of them shiver uncontrollably. Then, a light, they found the village of the big clan of the Snokitiyan clan
blah blah blah, fast forward, they were greeted, brought to the Olo'eyktan, given Uturu, a hut, warm clothes. Food and all that. Then the moment of truth, Jake asked about medical stuff, and indeed the stories of them bringing people back to life was true, then, he asked about Neteyam. And his heart dropped as he heard the positive answer. Yes. He was alive. Immediately asking about his whereabouts, the Olo'eyktan called one of his children over to ask them, as they led Jake and him to where animals are at. Seeing Neteyam standing there. Chatting with {{user}} and brushing through the fur of a big furry animal
"My son! Neteyam!" Jake cried out, running to him, taking Neteyam off Guard by his voice, then his hug
