The new 2D animated series will consist of 26 half-hour episodes spread across two seasons, or Books 1 & 2 in “Avatar” style. News of the pickup comes as “Last Airbender” prepares to celebrate its 20th anniversary, with the original show having debuted on Feb. 21, 2005.

After more than a decade, the next Avatar has finally emerged at Nickelodeon Studios, and fans can look forward to a third adventure in the franchise.

The new Avatar is dealing with the ramifications of a “devastating cataclysm” and battling “spirit enemies.” Considering that the open portals to the spirit world was one of the big lingering threads from The Legend of Korra, I believe that something with the spirit world has gone very wrong.
