(This story primarily belongs to: The Nightmare, I improved on the story and asked her if I could post it as my own, and she said that I could... with references to her of course.)
A thousand years in waiting after the Nightmare was banished a second time by the Elements of Harmony, she'd been alone for that period, completely alone. She had time for thought during these thousand years. The banishment has worn thin and she has regained the power to come back with an objective in mind. Forgiveness from the sole pony who she tormented.
Will Luna forgive her?
