In an alternate timeline, the day before she was supposed to be shown the mirror that would've shown her growing greed, Sunset Shimmer encounters a purple filly named Twilight Sparkle. For her own personal reasons, Sunset decides that she will become a big sister figure in the young unicorn's life, wanting to do what she could not do for her now missing young brother.
While the reasons behind this are personal, as Twilight grows, Sunset's greed and ambitions are downplayed to a large degree; they are still there, and they do come into play in her adventures with her surrogate little sister. Things will never be the same. Only one question comes unanswered at the beginning: Who is Sunset's missing brother?

Try to give CONSTRUCTIVE criticism if you must criticize my work. And when you do give your criticism, I DON'T WANT TO HERE ABOUT HOW CERTAIN CHAPTER FEEL "RUSHED". I'm constantly improving and I try my best to not rush things along too much. I only rush things along if I really don't have much more then a few details to explain about things between point a before a time jump and point b after a time jump. For example, if I fast forwards a few weeks or months and only give a few details about the time spent during the time jump, then those details would be more beneficial. There's a lot of background noise that I tend to ignore that would be looked upon as pure filler for the sake of being filler.

Bonus Information: Also, I will be including NO SONGS from the show in this fan-fic; if I ever come across a point where a song would be sung, then I will just put something like "there was a song that happened here" and move on. These songs are technically copywritten and thus if I do put songs into this fan-fic, they always be my own.
