Where I come from, the peoples of each nation specialize in a unique form of bending. [She guesses she'll have to explain that too] Some fortunate members of my nation have the unique ability to bend fire, and the more elite may in turn bend lightning.

Of course, those particular abilities are limited to me in this place, as there is no sun. However, I am not helpless.
