Take back Ba Sing Se

General Iroh and Princess Azula. Both responsible for trying to conquer or conquering Ba Sing Se. Both regret it soon enough.

Or an AU where Azula realizes earlier that her father is using her as a pawn, has to flee the palace, gets a redemption arc and teams up with Zuzu and Uncle Iroh.

None of the images are mine, the characters aren't mine and yada yada you get it.
