As a sometime storyteller, this is the sort of thing I love -- a throughly modern tale built entirely from traditional parts.
It's a difficult trick -- it's so much easier to slip into irony, or juxtaposition of ancient and modern, or easy humor. All those things can work, but the sheer craftsmanship of maintaining the fairy-tale world view and ancient culture while still telling a story modern readers find highly engaging is a beautiful thing to behold. The prose equivalent, I think, of some of those steampunk gadgets that are so popular right now.
So for the story: Bravo, good job, let's hear more!!
FWIW, my interpretation of the end was the she inherited the worlds and power of Tsi Sha, though she will presumably exercise it in a more benevolent manner.
I also thought the narrator was well-matched to the story, and did a wonderful interpretation -- I particularly liked the voice rendering of Tsi Sha.
The only part of the episode I didn't like was the fan introduction. For me, it was like hearing a toast at the wedding of someone you don't know very well -- you realize that there was something very meaningful there for them, but it just doesn't carry over.
If you're going to add material to the intro/outro, I'd like to see author comments. One of the things I like about buying anthologies of previously-published stories is that they usually add comments from the author about where they got the idea, how it fits into the larger scheme of their work, details of their life at the time, etc. that sort of thing would interest me, but a relatively spare intro/outro may be the best choice. Length does get to be a problem, at least for me.
