I need a name for my fimfic

Hi Everypony,
As I said before I'll be writing the first chapter of my first Fimfic in the next month. Now, I have the base of the fimfic, which is, "If Sunset Shimmer was the Girl-Who-lived". However, I'm having trouble deciding on a name. Here are the three ideas I have come up with:
A Magical Truth
A Truly Magical World
The Pony-Girl-Who-Lived
Let me know which one you think sounds good. Or if you can come up with a better name, let me know
