They watch and listen, wait in the shadows, in the reflections on window panes and from the light playing off puddles. Twilight Sparkle was taken, after helping with Discord's dismissal, and her life has been horror and fire since then, helping an alien creature known as the Librarian with his inscrutable tasks. She escaped, and now finds herself in a much darker, crazier Equestria, where Princess Luna rules, the death penalty is back, and Twilight Sparkle is almost as infamous as Nightmare Moon. Add that in with the changes her keeper had inflicted on Twilight and her life is almost like a waking nightmare.
