Most Ponies think they know what the Element's of Harmony are, but one seemingly common pony knows the truth. to the public, she is known simply as Spectrum Light, but her real identity is Light. She is the youngest and most reckless of the Children of Harmony (The true embodiments of Loyalty, Kindness, Honesty, Generosity, Laughter, Friendship, and herself). Light has died to save the world several times.
After her most recent sacrifice to destroy the shadowy entity that was, and still is, her polar opposite/mortal enemy 400 years before Nightmare Moon's return, Light had to wait 380 years for her rebirth (For she had used more magic than she usually did and needed the time to recover.), Light, as well as her family, had expected a normal rebirth, but that all changes when she is born at the exact same time as one of the ponies that her siblings had chosen to be the newest element bearers. Her connection to her siblings resulted in hers and said other pony's souls binding in a far stronger way than a normal bearer, resulting in them being like twins.
Now, as the evil that had always been her archenemy rises once again, she must work with the element bearers to defeat it. One question remains though.
Will her connection to her soul twin aid her in the final battle, or hinder her.

-tagged AU because of small things, some differences to the past, no spike (mainly because I doubt I could show his personality that well and I personally don't care for him), and because Fluttershy just regained her sense of self and was not turned back from the vampire fruit bat incident.
