I wrote a RariTwi fic for a Speedwriting contest last month. Afterwards, I realized that it works better as an original fic, so I filed off the serial numbers and expanded it a little. You can find the story here: https://offprint.net/work/r8UO1QyoI/the-wild-hunt

Description: "An old evil returns to torment the kingdom, and a young princess discovers that not all is as it seems."
