As 2014 continues, a new photo from "The Legend of Korra" Book 3 has fans excited for what's to come.

In a recent Tumblr update, "The Legend of Korra" co-creator Bryan Konietzko revealed another sneak peek of Book 3, this time featuring brothers Mako and Bolin.

"Prepare thy body for Book 3," wrote Konietzko as a caption.

This is the third image revealed from "The Legend of Korra" Book 3, the first featuring Lin Beifong, and the second with all your favorite animals on the hit Nickelodeon series.

Although this Book 3 photo is most likely all in good fun, some observers believe that this foreshadows what could be a focus on the Earth Kingdom in "The Legend of Korra."

In the photo, Mako appears to be practicing Earth bending in what could be Air Temple Island. Others, however, believe they are in a new setting altogether.

If "The Legend of Korra" Book 3 is shifting to the Earth Kingdom for "Change," it would also explain the creators' hint that Lin Beifong will be heavily featured in the upcoming season.

Several months back at a "Legend of Korra" art book signing and Q&A panel, a fan asked about Lin Beifong's presence in Book 2, and some were disappointed with the answer.

"Lin's Dad is just a mystery to me," teased Michael DiMartino regarding the identity of Lin's father and Toph's supposed lover. "We've got great stuff planned for Lin and her family. It's not right away, so don't be mad if it doesn't happen right away."

"Book 2, for the Lin fans...she's not very heavily featured in Book 2, BUT, very heavily featured in Book 3," continued Bryan Konietzko.

Will "The Legend of Korra" Book 3 reveal Lin Beifong's backstory by traveling to the Earth Kingdom. And if so, will Mako play a bigger role as an Earth-bending liaison?
