Sunset Shimmer has returned to Equestria with all the magic of the Elements of Harmony inside of her, traveling by accident ten years back into the past. Nearly all-powerful, but far from confident, Sunset questions her choices... and most of all, the possible consequences of her action. In particular, will the changes she's made to the timeline prevent her best friend, Princess Twilight Sparkle, from achieving her own destiny as an Alicorn?

What's an all-powerful Alicorn with a talent for magic supposed to do about it?

An unofficial crossover between LordBrony2040's "Sunset Reset" and a "Canon" Equestria Girls / MLP timeline. (At least until Sunset changes things, again.)
