When does Avatar: Seven Havens return?

The franchise is set in an Asian-inspired fantasy world in which some people can "bend" one of the four classical elements: air, water, earth, fire, or air. Only the titular "Avatar" is the only person who can bend all four elements and is responsible for maintaining balance in the world. A sequel animated series to Avatar: The Last Airbender, The Legend of Korra, ran from 2012 to 2014. The storylines of both animated series have been continued in comic book form.
