Avatar: The Lost Nations

The world of the Avatar is bigger than we imagined. Aang has discovered Terra Incognita, two previously undiscovered nations on the other side of the globe. Learning the ways of the Wood Clans and the Metal Empire may be Aang's only hope of averting a calamity to both worlds. (A canon edit of the events following ATLA. The comics, novels, and LoK are not canon).
