After his disastrous encounter with the Fire Nation princess in the caverns of Ba Sing Se, Aang's Avatar spirit was destroyed, never to return. Katara may have healed his physical body, but his spiritual one was much more difficult.
According to the Guru, there was an ancient ceremony that could restore Aang's link to his previous incarnations. The trouble was that it was purely theoretical. It called for one or two people to sacrifice their bending spirits in order for the Avatar to regain his.
Katara volunteered, and so did a repenting Zuko. He had made a deal with them; he would give up his bending and protect Katara through the lengthy recovery process. In return they would take Iroh with them to train Aang in firebending, and make sure that the Fire Nation people were left alone after the war, inasmuch as possible.
The sun was sinking to rest, and the moon rising from sleep as the Guru began the chant.
Some of you may have seen this before in my drabble dumping ground- I decided to pull it out and turn it into a story in it's own right. Updates on this will be sporadic at best, so don't get your hopes up.
