Avatar: The Last Airbender turns 20 years old on Feb. 21, 2025. So what better way to celebrate than with news of a sequel series?

As reported by Variety, Nickelodeon and Avatar Studios announced on Feb. 20 that a new Avatar show, titled Avatar: Seven Havens, has been greenlit. The 2D animated series, headed up by Avatar creators Michael DiMartino and Bryan Konietzko, is currently in production, and will span 26 half-hour episodes over the course of two seasons (or "books").

What is Avatar: Seven Havens about?

Avatar: Seven Havens follows the Earth Avatar who comes after Korra, meaning we'll have to say goodbye to beloved Legend of Korra characters like Korra, Asami, and Tenzin. It's been over 10 years since the finale, but I'm still not ready!

Based on Seven Havens' official logline, the Four Nations have changed drastically since we last left them, as the show is set in "a world shattered by a devastating cataclysm." That's right, we're looking at an Avatar-style apocalypse!

The rest of the logline reads:

A young Earthbender discovers she’s the new Avatar after Korra – but in this dangerous era, that title marks her as humanity's destroyer, not its savior. Hunted by both human and spirit enemies, she and her long-lost twin must uncover their mysterious origins and save the Seven Havens before civilization’s last strongholds collapse.

There's already so much to unpack here. What is this cataclysm? Did Korra have something to do with it, leading humanity to despise the Avatar? And what are the Seven Havens? Could they be the new name for a fractured Four Nations?

But the tidbit that stands out most from this description is the idea of an Avatar with a twin. This concept isn't new to the world of Avatar: Randy Ribay's novel The Reckoning of Roku reveals that Roku had a twin brother who died when they were young. But since Seven Havens' Avatar's twin is still alive, the upcoming series could offer an exciting twist on the Avatar dynamic.

Could Avatar: Seven Havens give us twin Avatars?

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?

But another approach Seven Havens might take could pull from Avatar lore introduced in The Legend of Korra. In Season 2, the series reveals that an Avatar's powers come from the Avatar Spirit Raava, a light spirit who fused with Wan, the first-ever Avatar.

Raava's dark counterpart, Vaatu, fused with the villainous Unalaq during Season 2's climactic battle, briefly creating a Dark Avatar. He initially destroyed Raava, but thanks to some spiritual intervention from Jinora, Raava was reborn within the Dark Avatar Spirit, and Korra rejoined with her after defeating Unalaq and Vaatu for good.

That's a lot of spirit-heavy lore, but it basically boils down to the fact that a little bit of Vaatu is still contained within the Avatar Spirit. So while Raava alone can't split into two bodies when twins are born, there's a possibility that Vaatu could split from Raava, giving us two Avatars: One dark, one light. That opens up a whole new can of worms for Avatar to explore. Could these twins be allies, despite the diametrically opposed spirits? Could having one of each kind of Avatar bring balance to a doomed world, or will it only cause more chaos?

Like everyone's beloved Foaming Mouth Guy, I'm currently freaking out about the possibilities, and I am ready for whatever Avatar: Seven Havens brings.
