What if, on the fateful day if the sonic rainboom, the day that the mane 6 got their cutie marks, Nightmare Moon escapes?

What if the nightmare had help? What if some ponies learnt of Nightmare Moon and worshipped her and yearned for her presence?

This fic is an early birthday gift from myself to myself. I was supposed to post a chapter for another fic but this idea clung to me. So far it is meant to be a one-shot but if it gains some attention (or if I feel like it) I'll make it into a series of it's own. Hope you enjoy!

Tags are subject to change in case it becomes a series.
