Sunset Shimmer isn't a normal girl. She can levitate objects with her mind, shoot hot energy from her palms, and when she's scared, she can disappear and reappear somewhere else entirely.

Her parents know. Her siblings know. What they don't know is how different Sunset really is.

When nightmarish creatures attack and kidnap her sister, Sunset ventures into the unknown and discovers a world teetering on the edge of total darkness.

What begins as a rescue mission turns into a struggle to save a kingdom, as Sunset learns just who and what she is, and the weight that comes with it.

When the princesses receive word of a mysterious illness breaking out at an archaeological survey site in the Badlands, they send Twilight, Spike, and Starlight to investigate. They find a bizarre sequence of markers, signs, and hints left long before pony civilisation as they know it, leading the way to place long forgotten by history. Together, the ponies must uncover their meaning, before an ancient evil from a past not even remembered by ponies leaves its mark on the future.

Strongly Recommended Stories:
The Brightest and the Best by Pineta - The events in this story are considered to be completely canon to this timeline and explain Twilight's entrance exam to Celestia's School for Gifted Unicorns. I cannot recommend this story enough.
MLP Annual 2013 - "The Fall of Sunset Shimmer" - As above, the 8-page short comic in the beginning of the Annual is also considered to be canon, though with some major variations.

Version 3.0 Edit: Extensive grammatical and mechanics changes. Adjustment to timeline of Sunset's second mirror experience.
