Avatar: Fallen Order
Avatar Fallen Order is a prequel video game to Avatar: The Last Airbender. The game is about an Airbender named Nima, a young Air Nomad who used to live in the Northern Air Temple. Unfortunately, when Sozin's comet arrived, the Fire Nation attacked and killed everyone he knew, leaving him as the only survivor(1). The game starts 10 years later. Nima was never able to get his tattoos, allowing him to blend in more easily than his brethren. Now 22, Nima continues a nomadic lifestyle as the Fire Nation's early years of Expansion have begun. Unable to use his bending and wracked with Survivors Guilt, Nima was unable to make many friends in this harsh new world, but finds a place along side the non-benders, whom everyone assumes him to be.
Despite the inherent danger, Nima finds himself working in a Shipyard in the Fire Nation Colonies, befriending the Earth Kingdom Laborers who are forced to work there, building Ships that will serve the war machine. Unfortunately, during a work accident, Nima accidentally Airbends to save a friend, assuming he wouldn't be seen by any Fire Nation Soldiers. Unfortunately, Nima and his workmates are reported and interrogated by a member of Sozin's Hunters, an elite team of Firebenders who are trained for one goal: To hunt the Avatar. Unfortunately for Nima, he happens to be the right age and an Airbender, and he is forced to go on the run across the Avatar World, making friends and enemies, and evading the Hunters along the way. With the Fire Nation constantly expanding, Nima must constantly be on the run, knowing that he is most likely the last of the Air Nomads.
The game is filled with nods and references to The Last Airbender, such as being able to see the Southern Air Temple and see the same locations recreated, along with Ba Sing Se and the Si-Wong Desert.
(1) I refuse to believe that all the Airbenders were wiped out in one stroke. I do believe all of them being dead by Aang's time, but not all at once.
