Destinies Rewritten is a For Want Of A Nail AU by Master Ghandalf. It centers about how Lu Ten surviving the siege of Ba Sing Se, which led to Iroh winning it, altered the world as a whole. The story is divided into books, as in canon. It is an In-Progress story, and can be read here.
Destinies Rewritten provides examples of:
- Affably Evil: Lu Ten.
- Bad Boss: Ozai is this to his men, killing one for letting Aang escape.
- Dead Fic: Not updated since 2015.
- Enigmatic Minion: While the Dai Li work for the Fire Nation, what they are up to is not at all clear.
- For Want Of A Nail: Lu Ten did not die in the siege, leading to Iroh not retreating from Ba Sing Se.
- Pragmatic Villainy: Iroh lets earthbenders live and does not imprison them, provided they fight for him and the Fire Nation.
- The Starscream: Foreshadowed: Ozai wants the throne, but cannot get it due to Iroh.
- Well-Intentioned Extremist: It is unknown what Iroh and Lu Ten's beliefs are, but quite likely they are well meaning, like in canon.
