Greetings 1 of 2.
It has been a few years since the end of the Fire Nation war. Times were peaceful, a much earned rest from all that was lost to get here.
Be it as someone who worked alongside her, a mere Fire Nation officer, or someone who went against Ty Lee and Ozai's angels (you are free to elaborate if you wish), you are, willing or not, now sharing a place with one of their ex-agents.
You are hanging around, bored out of your mind when you eventually find a scroll. Perhaps from a previous mission, perhaps from someone else, maybe it just wound up at the place you were in through oddly convenient circumstances.
Not having much better to do, you take a chance at reading it in your bed and immediately regret it, a golden glow emanating from it...
By the time you realize it... It seems you've shrunken doll to the size of a toy. (Whoops?)
