Welcome back to Pandora. Disney just released the first trailer for Avatar: Fire and Ash, the third installment in James Cameron’s epic sci-fi saga. Set on the alien moon of Pandora, the series follows the Na’vi as they defend their homeland from human invaders who are stripping it of its natural resources.

James Cameron's third Avatar movie is turning the rules upside down, introducing a nefarious Na'vi clan as the human invaders go all-out.
