It starts with an inside look at the different personalities of our three hero's then becomes a more natural way of reading the story. Brought together by our evil mastermind villain. When they are all one no one -pony or human- could ever make sense of what is happening in there collective minds. Will they be a tool for the conquest of Equestria? What could the bad guy have over them that they don't just go straight to Celestia with this latest attempt to dethrone her?

(-WARNING- self insert pony oc turns into an alicorn!! Don't read if you are not open to stories going the way the writers want them, and pony oc being in fan fics, or the fact that ponies can be, and will be alicorns other than canon ponies)
