So I thought it was a bit odd, the entire power to "energy-bend" and give people bending. In the show Legend of Korra
Wang is given fire by a Lion Turtles, and is given various other elements from the others that existed.
This doesn't explain people with the lack of bending, as
Wan's people and friends all gain firebending powers to live in the wild.
It got me thinking about non-benders, and their lack of bending.
Are they descended from some people who never gained bending from the Lion Turtles? Could they be given the ability to firebend by the remaining Lion Turtle (and completely remove the plotline of Season 1 of LoK)?
