Backstory:
This young filly is the blood of royalty. She is the ancestor of one of the many gods of Equestria, but the mystery is...Who?
She has no horn, nor does she have any power of flight to speak of. Although one thing is for sure: The marking on her rear leg has immense magical power. In fact, some say that it isn't even magic. But magic that lives. Magic that can power itself. Magic that lives within itself. It is hard for many to understand, but she is only but another royal mystery, aside from the others, that had appeared the same day she had, for some strange, but coincedental reason...
...The princesses keep her locked up in a castle, far from any pony city for safety. A secret castle that only ones with royal magic can enter. One that is guarded by not one, but seventy manticores...
But some people don't believe the legends.
This royal filly is pretty normal though---Aside from her strange marking.
Because of the immense power she holds within the marking on her rear leg, many had believed she could have been stronger than luna and celestia theirselves....
So therefor, she has been considered a stepsister to the gods. Earning such a title truly takes honor, but she had more than enough to prove that her magic, was intense...and living. Not like any other.

Because of this, Celestia had ordered for her to wear special magic-protection armor. This way, nopony else could see what power she could hold...Eventually, they had feared other ponies would begin asking why she wears armor, but it was good enough for now.
It was also easy to notice, she looked rather different than otherponies herself...
The armor began to weaken, at the same time has she had begun to grow stronger, at the same time...
This was truly a strange mystery to yet unfold....
