Once again, I mourn FicWad's lack of communication. I will respond to your question here also, bommor, even though it makes me feel as if I'm cheating and merely upping my review number. It is a rather less known crack ship: Katara/Fire Nation Magician-Performer from "The Deserter." All credit for the ship goes to Whomever, the extraordinarily original webmistress of AVATARD: The Last MiSTer.
