After attempting to impress the judges during her entrance exam for Celestia's School for Gifted Unicorns, something transpires that alters Twilight's life irrevocably, as well as the destiny of all Equestria. In a very literal manner, Twilight metamorphoses into the embodiment of magic, much akin to how Discord embodies chaos. How will this unprecedented transformation shape forthcoming events? And how will Twilight grapple with mastering the newfound god-like abilities that have been unexpectedly thrust upon her?

After a display of dissatisfaction turns into a revolution, Celestia found herself meeting a most unfortunate end at the hands of the mob. Being powerless to stop them or even muster up the courage to sway their minds, Twilight flees Canterlot and vows to bring Celestia back to life.

Through this vow the young unicorn starts to venture into territories of magic either hidden, forgotten, or unknown. On this path she encounters creatures and ancient entities that boggle her mind and aid her in her quest, but Twilight fears she might be losing the grander picture. Is the end of her journey bringing her beloved mentor back to life or is she slowly being corrupted by the miasma she now wades through?

Once upon a time, in a story we all know and love. There was a unicorn, who shined as bright as the sun, she was a prodigy in magic and Princess Celestia’s prized pupil. One day, she was sent to Ponyville and met her best friends: Applejack, Pinkie Pie, Rainbow Dash, Rarity, and Fluttershy. She and her friends were able to defeat any foe that came their way, and spread friendship and harmony throughout Equestria... that is, until Opaline Arcana came, she wanted power, all of it, she even stole the dragon magic, and became a Fire Alicorn. Twilight knew she wouldn’t be able to stop her, so instead, she put Ponykind’s magic into three gems, and put an invisi-bubble around Equestria, so that the evil Alicorn could never harm them again, but the seeds she had planted started growing until each of the three tribes took their gem and separated. Until an earth pony, Sunny Starscout reunited Equestria with Izzy Moonbow, Pipp Petals, Zipp Storm, and Hitch Trailblazer in one MASSIVE quest. Together, they created new magic and defeated the alicorn that even Twilight couldn’t beat.

But I’m trailing off, aren’t I? Ahem, you know that story, obviously, but I wanna show you a story, where Twilight Sparkle, Sunny Starscout, and their friends existed simultaneously.

"There are twelve Elements of Harmony, but only eleven are known so far." Twilight read as she flipped to the next page. "Honesty, Selflessness, Kindness, Empathy, Laughter, Creativity, Generosity, Confidence, Loyalty, Courage, and Hope, the twelfth is a total mystery..."

When the human Twilight discovers the fossilized remains of an alicorn, her Equestrian counterpart is sent down a path that will unravel a secret hidden for two-hundred millennia.

Upon returning to the human world, Sunset Shimmer finds Canterlot City twisted into a biomechanical hellscape, with all living things transformed into grotesque mockeries of their former selves. Led by the human Starlight Glimmer, the forces of Phyrexia loom omnipresent over all aspects of life.

Joining her six closest friends, Sunset is now faced with a seemingly impossible task. Can the magic of friendship find a cure for phyresis, or will the world be forever doomed to compleation?

Sunset has once again become a pariah, the students of CHS have turned against her, and even her own friends have abandoned her. At her lowest point and without her friends, Sunset is left vulnerable as the students voice their frustration at her being Anon-A-Miss. But she still had one friend who believed in her and that was Twilight Sparkle, with her words of encouragement, Sunset is reminded of who she is. With her confidence back, Sunset begins to take back control of the school and hunt down Anon-A-Miss.

After seeking refuge in Equestria during the Anon-A-Miss fiasco, Sunset Shimmer is stranded in Equestria. Convinced that she's just not cut out for friendship, Sunset throws herself back into her studies. Unfortunately for her, all the magic around CHS has attracted the attention of a certain spectacled scientist. When her device accidentally pulls the mysterious energy from the statue in front of the school, she is shocked when an amber unicorn was pulled out with it. With the portal not working, the two must work together to gather the energy needed to send Sunset home from the only magical source left to tap: Sunset's former friends, all while dealing with the overbearing principal of Crystal Prep as the Friendship Games approach.
