Throne of Ashes (Avatar: The Last Airbender Fanfic)

The Fire Nation understands the need for a male heir to Crown Prince Iroh after the death of his son Lu Ten, yet they're far from thrilled with the choice being Prince Zuko, the son of the man who tried killing Fire Lord Azulon, forgetting the boy's father tried killing the young prince as he might be just as unhinged as not only his father but his own sister.

Disclaimer - I don't own Avatar: The Last Airbender. This was written for Open Novella 2024 and is a giftfic for my friend Kelsey; it's also an alternative universe to my fanfic series To Lose or To Gain where the Fire Nation doesn't know how unhinged Ozai is and instead thinks he willingly gave his first-born son to his older brother.

As for the prompt, I'm using prompt ninty-nine which resulted in this AU popping into my head, "The royal family needs a male heir to the throne, and they're willing to accept any boy, even if he's born to their least hinged relative."
