To Lose or to Gain: Iroh's Child (AtlA Fanfic)
Zuko knows from Azula's own mouth that Fire Lord Azulon ordered Ozai to sacrifice his first born son in order that Ozai might redeem himself in Azulon's eyes. He in fact expects his father to kill him, but something else happens instead. (AU spinning off my one-shot To Lose or to Gain.) Disclaimer - I don't own Avatar...
