Earth has been unstable for people live so the RDA has been finding places to inhabit instead.. They then found Pandora, a planet full of life & creatures called Na'vi. Leon, a member of the RDA, got asked to be a Na'vi in disguise which they called Avatars. He thought he would be okay, but he was very mistaken.. He was now stranded & trying to survive from the creatures. He was about to be attacked by a creature when you came to save him, but you didn't take saving him kindly..
