"The Legend of Korra" Book 2 is just around the corner, and Nickelodeon has released a brand new online game to and concept art to celebrate the occasion!

The game itself is fairly basic, with bending attacks and platforming combined into one as fans play as Korra to combat dark spirits.

"Personally I have struggled to play this game as I find the jumping to be horrifically terrible. It is so bad that the game is more frustrating that fun. It seems interesting enough, with some unlockable special moves, including the Avatar State," writes Avatar the Last Airbender Online founder Morgan Bannon.

However, "The Legend of Korra" Book 2 concept art is certainly illuminating and exciting to see, and a slew of new concept art have been released for your viewing pleasure.

The concept art include many locations like the Northern and Southern Water Tribes, and images that appear to foreshadow the conflict of Book 2.

One particularly interesting image is that of the Glacial Spirits Festival, which will be introduced in "The Legend of Korra" Book 2 premiere episode, "Rebel Spirit."

But what is the Festival, exactly?

"Originally, the festival was a solemn time for fasting and meditation, during which tribal elders would commune with the spirits. As a result, spirits would dance in the sky, creating beautiful displays of light," says the Avatar Wiki.

"By 171 ASC, the festival had become a frivolous carnival; it spurs recreational games, including water-guns, where stuffed animals, such as flying bison, are offered as prizes. Fried foods upon sticks and cotton candy are offered as snacks. Also, a royal feast is held in honor of the respected chiefs of both the Northern and Southern Tribes. This banquet includes the presence of numerous attendees during which animal shows may be featured. The festival, while originally for the Water Tribes, is open to all foreigners wishing to attend."

It appears the Festival will be a major set piece in the Book 2 premiere episode. For example, it appears to be where Bolin meets Desna and Eska for the first time.
