Julia has been hunted since birth. Before her very existence she had become a legend - The Maverick - the one to save Equestria from destruction. She carries this title as a burden. Ponyville has become her escape to live a normal life. Still, her past continues to haunt her and finally catches up - threatening Ponyville and its residents. With a new persona and new-found friends including Rainbow Dash, Julia faces her demons and turns them against themselves as The Mysterious Mare Do Well.
ponders........ hmmmm. this........ might be interesting. will keep an eye on it. see where it goes perhaps.
though i have to plead one thing....... please don't start killing off the mane six or something........ oaky i know that is a really random thing to ask, but i have endured like nine stories lately where the writers thoguht, oh let's murder the six mares that fought off changelings and chaos beasts like they were blondes in a horror movie......... not pleasant.
.......will admit you have to fix up the writing though. i overall like the concept and origin but the writing is a bit clunky.
