One dark and ominous night, Nightmare Moon surrenders herself to the princesses.

No one is exactly sure why. They only know that she ended up in the psych ward with little recollection of the event and seething hatred for the very pony who ruined her life. They only know that her mental illnesses keep consuming her. They only know that she is dangerous, and she doesn't know it.

Nightmare Moon herself is angry and mad; but she swears its not the crazy kind of mad. She has an explanation. But what other explanation is there when your mind feeds off of your feelings? And when will she finally relent and let herself get help?
