Loved it

"I loved the way you used the main story so precisely to continue the story as if it was official. The only detail in the story is that Aang did learn how to use energy from the lion turtles, so technically Aang was a "true balance avatar" before Korra was (that is my understanding since Aang was capable of removing bending even though Raava and Vatu weren't united or even mentioned yet)."
