Nickelodeon has greenlit an animated series set in the world of its beloved Avatar: The Last Airbender. The new show, titled Avatar: Seven Havens, has a 26-episode order and will follow a new Avatar. The series will be the third in the Avatar -verse, following the original show and The Legend of Korra .

The trailer features the MTG logo doing some impressive airbending, with the familiar sounds of the show’s original opening in the background. And the caption understood the assignment, as it begins with the well-known line “Long ago, the four nations lived in harmony, but everything changed when the Fire Nation attacked.”

There are a few ways Seven Havens could approach an Avatar with the twin. The first could be similar to the Katara-Sokka dynamic from The Last Airbender, where one sibling is a bender and the other sibling is not. How would knowing your sister is the most powerful bender in the world affect your sense of self-worth and your relationship with her?
