A thousand years ago, Princess Luna becomes overcome with negative emotions, and one day finds herself unable to control her own body. Her mind intact, she has to deal with whatever's taken control of her.

Formerly titled "Luna's Nightmare", changed on Nov. 6, 2015, to equally reflect all three chapters instead of just the first one.

Now with a cover image! "A Pony Moving On" by muffinshire on deviantArt.
