After the loss of avatar Korra, the world was anxious for the appearance of the new avatar. And so, they discovered Jung Yerin, a young girl from the middle ring of Ba Sing Se, the earth kingdom capital.

After years of training under the close evaluation of masters and instructors, she was finally granted the right to explore the world at 19 years old in search of expanding her knowledge on the cultures of the world around her and to improve on her bending.

But there is a new evil afoot, an underground terrorist organization ready to strike at any moment to destroy the avatar where she stands and to throw the world into complete chaos.

It’s up to Yerin and the other people she meets along the way to stop them with everything they've got.
