Watch The Legend Of Korra Book 4 Preview Video Before The Release Date

Before "The Legend of Korra" Book 4 begins on October 3, fans have unlocked a special preview clip of "Balance" before the premiere.

"We couldn't wait any longer, the very first clip from Book 4 is here," said the KorraNation Tumblr.

"Interesting clip in that Korra seems to have decided to return home to the Southern Water Tribe for a few weeks, so I guess at some point there is a time skip where we see Korra get her new Book 4 design," wrote Morgan Bannon of Avatar the Last Airbender Online.

Meanwhile, the premiere has been revealed to be October 3.

"It's coming out October 3, get ready," said DiMartino. "Every Friday, on Nick.com and the Nick app, you can watch a new episode. So stay tuned. It's going to be awesome."

As reported by Emergency Awesome on YouTube, images and screencaps from a "Legend of Korra" Book 3 TV trailer appear to be from the final season of the animates series, and they provide possible spoilers as to what Book 4 will revolve around.

First an image that has been circulating the web is that of Kuvira, who was somewhat heavily featured in the finale episodes of "The Legend of Korra" Book 3. Based on the image, many fans theorize that Kuvira could be a villainous character in Book 4.

"It seems like based on this, [Book 4] will be a continuation of end of Book 3, but there won't be a giant jump in time," said Emergency Awesome.

"We don't have any kind of confirmation on what Kuvira's backstory is, other than what Suyin has told us, but there are a lot of really cool theories."

One popular theory is that Kuvira is the love child between Zaheer and Suyin, based on a photo shown in a "Legend of Korra" Book 3 episode.

"It all stems from this picture that was in Suyin's office of her and her circus troupe," added Emergency Awesome. "It just looks like this person is Zaheer, so it's possible they had some kind of relationship, and Kuvira was the result of that."
