This is a crossover with the 1986 Jim Henson film, Labyrinth. Yes, THAT Labyrinth, with David Bowie and goblins and glitter all over the place.

In general, it is a very SIMILAR plot to the film, but with many, many, MANY significant differences to keep consistent with the characters and their personalities.

Also, Twilight is a filly. I'm doing this as a take-off-ish-sort-of-thing of my roommate's (Chatterjoy) story, To Be Young Again, and I do have Filly Twilight's POV alternating every chapter or so, like she does, but I might add more than just 2 POVs.
