As "The Legend of Korra" fans eagerly await season 2 and the San Diego Comic-Con panel, a new interactive book, "The Legend of Korra: Enhanced Experience" has been released on iTunes with new information on the upcoming Book 2.

Fans will meet Korra's waterbending cousins Desna and Eska in the upcoming Book 2: Spirits.

"Korra's cousins are sixteen year-old twins who have a strange connection and seem to communicate without saying a word," says the official description.

"They're both Waterbenders, and when they work together they can accomplish amazing feats, such as shooting entire icebergs at opponents. Korra has always found them incredibly annoying because they look down on her for being a rube from the South, even though she's the Avatar."

And next up is Varrick, who was last seen in a sneak peek picture posted by show co-creator Bryan Koniezko.

"Billionaire shipping magnate from the Southern Water Tribe. He's a little eccentric, but very charismatic. He spends most of his time traveling the world on his monster yacht and living a fabulous lifestyle. Born a poor seal-hunter's son, he built his business from a single canoe into a global power. A consummate dealmaker, he's always looking for angles to expand his business empire. He is currently making a deal with Asami to become Future Industries' shipping partner. There are rumors that he deals with underworld characters and gangsters if he thinks it will turn a profit, but that has not been verified."

And lastly, the title of the first episode of season two is "Rebel Spirit."

Hm, does this have something to do with the spirit world we've been teased about?

Don't forget to attend the Comic-Con panel on July 19 if you have the chance, as the potential release date might be announced then!
