Note: This story takes place after Equestria Girls, not Rainbow Rocks

I never chose a bitter heart... Nor a greedy one. I never chose to hurt anypony, but my soul forced me. My soul is a burden and whatever way the portal changes my body, I must carry the burden of my soul.

After the events of Equestria Girls, Sunset Shimmer returns to Equestria seeking guidance from her old mentor, but when she returns, Celestia denies her. She has but one choice now that the portal is locked... Princess Twilight Sparkle.
