Deep in the everfree forest, in the so called "abandoned" castle of the pony sisters, was a lonely soul.
"I have to get my revenge on those blasted ponies!"
As the soul floated around she was plotting revenge on the main six for defeating her. Even though they thought they finished this villian they were mistskened.
"I Nightmare Moon will plunge the world in total darkness!"
But something hit her like lightning, she needed a body, a pony to become her. She needed somepony whith power, she wanted revenge on Twilight Sparkle, so she was out of the question. She wanted a pony who was apart of the main six, the yougest out of all of them. The pony that was a good host was Rainbow dash!!
"But how am I gonna get Rainbow to get all the way over here? She would surely wouldn't want to come here again."
As she floated along thinking of ideas, the perfectly good idea came to her!
"I got it"!
With the little bit of magic she had, she made a sirren out to Rainbow Dash to come to the everfree forest.
"You will come to me so we can be one...
Rainbow Dash."
