1. Spirits In The Physical World
Book 3 is 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. Due to the Harmonic Convergence and her battle with Unalaq and Vaatu the world slightly shifted, and Korra then decided to leave the Spirit Portals open- uniting the Spirit World and the Physical one in a complete show of peace and amity. I also hope Korra trains some more with Jinora, because if there's one person who knows something about Spirits, it's Tenzin's eldest daughter. I'm looking forward to the world becoming accustomed once more to co-existing with Spirits, I also hope it means we get to see past faces. Perhaps more spirits of ancestors we're familiar with, maybe even past spirits- although I don't know if I relish or rue the idea of possibly seeing Koh the face stealer again. These are just a few things I've heard that I'm rather excited about, let me know if you've heard any other news regarding Book 3 and what you're most looking forward to. Maybe you disagree with my list, perhaps you want more MaKorra? Hit that comment button and chime in!
