Ever since her imprisonment, Nightmare Moon had waited patiently for her return to Equestria. She waited for the day when the spell weakens and the stars aiding in her escape. Then one day she felt a strange surge of magic surrounding her. Believing this to be her return, she allowed the strange surge to take her away. However, instead of taking her to Equestria, she is instead taken to a unknown world, full of these hostile inhabitants called Orks.
