See through my eyes.

You’re an intelligent person. A seriously intelligent person. You’re calculated, observant and quick as a whip. This is how you got into the Avatar program. However, all that came crumbling down around you when the war between man and Na’vi broke out. They weren’t accepting any more ‘dream walkers.’ However, two years later, as any war would wipe out some of the opposing populations, the Na’vi were dying out faster than they could reproduce. So, the inhabitants of Pandora bargained with Earth. Pandora would provide Earth with its most expensive mineral and Earth would continue its Avatar program. You are one of the lucky ones that are chosen to go first. But, all that so called ‘luck’ is washed away as soon as it arrives when you get to the mystical other planet.(It all takes place after the events of the movie)
