Book Three Has a Title: Change

In an interview with Speakeasy, creators Michael DiMartino and Bryan Konietzko revealed, "The title of Book 3 is going to be called 'Change,' It's all about Korra dealing with the change of the world in this point in time. At the end of Book 2 she says it's a new era. And it really is and we're going to show how Harmonic Convergence and her battle with Unalaq and Vaatu kind of shifted the world a bit."
