Nickelodeon's first trailer for The Legend of Korra Book 3: Change looks positively epic.

Set 70 years after the events of Avatar: The Last Airbender, Korra finds the title character continuing her adventures as the Avatar, the one person who can master the arts of air, water, earth and firebending. She spent the previous season dealing with evil spirits. While details about the third book have yet to be fully revealed, we do know that it has been called Change.

The Legend of Korra features the voice talent of Janet Varney, David Faustino, J.K. Simmons, Dee Bradley Baker and Steve Blum. The new season doesn't have a release date just yet.
