My grandfather's, actually. My father suggested to Azulon that my uncle's- his older brother's- birthright be obliterated after his son's death. The suggestion made perfect sense; after all, my father had two children to continue his line, while Iroh had none. But Azulon grew angry at the suggestion that more suffering be added onto my uncle's plate, and decreed that Zuko be killed so that my father too would know how it felt to lose a child.

It was a lot of silly business, really, and proof that my grandfather had grown soft in his old age.
