Shadowbender is so cool. I loved how you made Kida fit into that world, setting here in strategic points to clash with possible narratives of the final chapter of The Last Airbender. I always wondered what happened after the last episode.
In the new avatar, Korra, you only get clued in to some parts of Aang's life and you have to assume about most of Zuko's. I like your spin on things. I do wonder why if she's some dark child, is she overly emotional and naive. But that's a personal opinion.
I'll be sure to keep reading. Your story has spiked my interest.
