Two screen shots of Book 2 of The Legend of Korra have surfaced and they both provide some interesting insight on the second book in the series. The first picture (above) depicts a smiling Korra and Asami standing in a desert-like setting in front of a tall building. By the looks of the building, the architecture looks to be similar to that of a Fire Nation building (the building is red, too). This could suggest that the setting of this picture is the Fire Nation itself, meaning Book 2 will not be solely set in Republic City.
I recently wrote a prediction article suggesting that the setting of Book 2 of The Legend of Korra could be outside of Republic City. This image could very well confirm that theory. Other than that, we can confirm that Asami does stick around with Team Avatar despite her tensions with Korra and Mako.
The second image released, however, is a bit harder to decipher.
As you can see, the second image is essentially a montage of screens from a Legend of Korra Book 2 episode. We can see screens of Korra bending, Meelo being…Meelo, and Tenzin.
This is our first plausible evidence of Book 2’s content. Recent rumors have suggested Book 2’s title and release date.
