In her youth, Twilight Sparkle discovered a way to infuse technology and magic. 20 years after her breakthrough, she is now the CEO and founder of Sparkle Industries, and one of the wealthiest ponies in Equestria. Her relatively perfect life goes sour, however, when she is captured by a group of griffons who want to steal her technology.

One day on a trip to the market, Fluttershy discovers that things are getting caught in her tail. What kinds of things? Interesting things. Strange things. Their origins are all questionable at best.

Tonight, Fluttershy is going to meet one of those legends, and it's going to change her world forever...
