excellent, you portrayed Azula's cunning and fondness for political power plays very well

Long Feng sounds intelligent. Something I think all the good guys in Avatar could benefit from.

This is very very well written; I like your style and characterization. However, I am a bit dismayed as how this is considered "complete" according to the progress status. This feels more like a good buildup for events to follow, as having Long Feng travel to the Fire Nation is something that has not yet been confirmed in the actual series. It was an interesting read but I didn't feel that it got anywhere.

A tiny concern; I find it strange that earthbenders would feel so out of their element on a ship. During Imprisonment, Haru was on the metal brig, which contained no earth save for some coal, for maybe a day before Katara met him. He looked fine.

Overall, well written. I liked it.
