Dr. Anson Langely was a human xenobotanist and one of the known avatar drivers. Raised in one of the largest and most crowded cities on Earth (London, England), Langley was happy to be accepted to the famous lunar University of Cassini at the sparsely populated southern pole of Earth's Moon. Here he excelled in the study of plant growth in lower gravity environments, making him an ideal candidate to study the plant life on the Pandoran moon.
Now in the sixth year of his mission, Dr. Langley has proven to be a valuable asset in Na'vi-human interaction, earning the rare honor of joining the Na'vi on their hunting parties.
Dr. Anson Langley defected with fellow avatar drivers Dr. René Harper and Dr. Jerome Epstein. The Tipani Clan sheltered him in their village Six Deep, and his link shack was moved there. If the player chose to side with the RDA, Able Ryder is given the assignment to kill him. If the player sides with the Na'vi, his fate is unknown.
