There’s no end to the monsters that lurk in the dark.

Ghosts, werewolves, mad scientists, cultists, mutants, zombies, vampires, aliens and more lie in wait in the dark corners of Equestria, terrorizing the night. But the most infamous and dangerous of them all is the legendary witch Twilight Sparkle, with a five hundred million bit bounty on her head.

Seeking fame and fortune, Rainbow Dash sets out to defeat the legendary witch and collect the massive reward. The one thing she wasn't counting on was Twilight being less evil than she expected.

Surrounded by the Everfree Forest, filled with delinquents, devoid of morals and any real sources of magic, Ponyville is the worst place to live in all of Equestria. But it also has the cheapest rent and Twilight's life just collapsed to the point where she can't afford to live anywhere else.

Perhaps the only thing Twilight has going for her now is that Rarity, the most powerful pony in town, has taken a liking to her. Rarity is eloquent, but the leader of a gang. She's beautiful and intriguing, but the most irreverent and delinquent pony Twilight has ever met. Rumors swirl around her. Some ponies even say she and her entire gang are all vampires.

But Twilight is smart enough to not give in to temptations. Or join a gang. Or become a vampire.

Many things happened when Pinkie Pie tried to convince her siblings to move to Ponyville. Rainbow Dash lost a hoof wrestle with Limestone, Twilight learned just how far one may shove a pony's head into a trombone and Marble got left behind as usual. This time, the shy earth pony didn't mind being forgotten as it meant they could spend more time with the first kindred spirit they have met in a long time.

Alone with kindest pony Marble had ever met, the earth pony found themselves drawn within those sparkling eyes and now must return to Ponyville in hopes that Fluttershy feels the same way.

Warning, though this story has no sexual content and is rated E, the sequel gets hot and heavy, you have been warned.

The lady Rarity is infamously picky with her stallions and despite spending decades up at her mansion alone she has not had a returning suitor, only her pink maid and that yellow gardener ever return to the everfree mansion. Rumour is, unfortunately, all the town has to go on but with the gala coming around again in a few short weeks the town is abuzz with what their small time nobility will do. Will this be the year Rarity finally graces Canterlot with her presence? Why hasn't she gone all these years despite being explicitly invited by the princess?

Twilight has been chosen as this year's addition to queen Nightmare Moon's mysterious cadre of personal students. She gets to live in a castle, receive lessons from their sovereign, yet her parents remain sad for some reason.

Twilight doesn't understand why they aren't happy for her.

It's over. She's been with Celestia for years. She's absolved Luna of her crimes. She's been instrumental in defeating Sombra, and has revealed a Changeling invasion. She's even helped in reforming Discord. And now, her time is over. In the time that she's had, she's tried to do her best. She's tried so hard to live up to what other ponies expect of her.

And they were happy with how she was shaping up.

They wanted her to succeed.

Now all they want is to see her dead.

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.

This story has been rewritten as The Twilight Effect.

Twilight Sparkle had always been a bit strange. Whether it was her unconventional name, her naturally purple and pink hair, or her persistent belief that science held the answer to everything, it was enough that this strangeness prevented her from forging any sort of relationship up into high school.

Now, just starting her final year, something mysterious happens at Kanterlot High School. The kind and benevolent principal will no longer speak to her. Students with names just as weird as hers are popping up out of nowhere in the same day. Everywhere, everywhere she turns there’s talk and sight of magic, followed up by a terrible monster being unleashed on the school. And worst of all? Twilight finds herself almost willing to believe it all.

Almost. Good thing she’s smart enough not to, right?

A retelling of the season one opener. Sunlight. Art by me!
