Sequel: Left Behind: Sunny Disposition
Apparently it was scouted and is on EqD too

Nightmare Moon was meant to be released after a thousand years. A momentous occasion for her but terrifying for all the ponies on her day of freedom. She would get revenge on her sister and cover the world in darkness and shape everything to fit it.

That was the plan, at least. Instead, something went awry with the spell and she wasn't released when she was supposed to be. The mare-in-the-moon is brought into a world with stagnated technology, giant cities, and no sign of her sister or any of the other immortals. In fact, ponies don't seem terrified of her at all, and the stay within the core of her powers infused and changed the alicorn's body drastically.

The alicorn had no obstacles left! But...she was also a relic of the past. A past everyone seemed to have forgotten. A past she could no longer look upon.

Big thanks to Kryostase for helping spot errors I've missed.

"My name is Lyra Heartstrings, and you will not remember me. You won't even remember this conversation. Just like with everypony else I've ever met, everything I do or say will be forgotten. Every letter I've written will appear blank; every piece of evidence I've left behind will end up missing. I'm stuck here in Ponyville because of the same curse that has made me so forgettable. Still, that doesn't stop me from doing the one thing that I love: making music. If my melodies find their way into your heart, then there is still hope for me. If I can't prove that I exist, I can at least prove that my love for each and every one of you exists. Please, listen to my story, my symphony, for it is me."

Technology has granted us many wonders, from an abundance of sustenance, buildings that reached for the sky, and a network that digitally connects the world being just a few. However, with these advancements must come a price; there’s little purpose in merely living, smog covers cities and chokes their inhabitants, and the night is bathed in a dull glow that blocks out the stars.

Too many ponies have become complacent in what they have, but one, a creation of technology herself, has had more than enough of it. The structure of society in this modern age has trapped and tortured her for years, and the technology and magic that suffuses the world only adds fuel to the fire, but when an opportunity presents itself in the form of a beautiful and free travelling showmare, she may finally get the chance to escape she’s been so desperate for.

My entry to the Sunset x EqG Villain Second Chances Contest

Princess Celestia has retired. Her reign is over, and her stewardship of Equestria is at an end. But that doesn't mean that her little ponies have stopped needing her. Her time as supreme political puppet master has given her a unique set of skills; networking, guiding, mentoring, and of course a little bit of manipulation. So she opens up a new business: Auntie Tia's Matchmaking Service!

Ponies come from far and wide to tell Auntie Tia their romantic woes and ask for her help, and she never turns away a pony in need. But her new clients are among the toughest she has ever faced - have Celestia's matchmaking abilities met their match?

In her latest bid to impress Princess Celestia, Twilight takes to mapping out the Everfree Forest. Along the way she discovers that some things are not to be disturbed. She also learns to get a second opinion whenever Spike offers her advice.

This story is a sequel to A Taste of Stardom

A new normal brings new problems. Chrysalis has a job - a good, well-paying job she actually enjoys - and one of the conditions for keeping that job is the mandatory yearly physical. Well, that should be no problem for the Queen of the Changelings... right?

(Reading 'Taste of Stardom' first is highly recommended.)

My name is Twilight Sparkle, and I am a wraith.

A comment driven story following an alternate universe where Twilight is hundreds of years old, Sunset stayed Celestia's pupil, and everyone has the hots for Twaith. Okay, almost everyone. Lets see where this goes!

Teen Sex because of expectations of the internet... and myself.

This story is a sequel to The Many Deaths of Twilight Sparkle

Twilight has discovered that Alicorns can 'respawn' when they die. Think of the possibilities! She quickly assembles a crack team of scientists* to test the frontiers of this new power.

*IE whoever was willing to respond to a letter asking for 'suggestions of practical uses for the death of an alicorn'.

An unofficial sequel to "The Many Deaths of Twilight Sparkle".

Rated T for references to death and suicide, though in context those things don't really happen.

Just over a decade ago, two budding entrepreneurs made a major discovery: changelings convert love into power. And that power could be extracted.

Spurred on by the sudden infusion of energy, Equestria has rapidly industrialized and modernized. Transformed, technology and society has advanced by leaps and bounds - all thanks to Flim/Flam Corp and their changeling batteries.

Not every pony is accepting, however. Not every pony is okay with mass-produced changelings kept in tanks to turn Equestria's ambient love into electricity.

After years of leading her rebel organization on a campaign against the changes, the former Princess Cadance has finally made a breakthrough. Though it has cost her dearly, she's found the key to bringing down Flim/Flam, freeing the changelings and returning Equestria to its normal state.

Unfortunately, Shining Armor - her personal Javert - is blocking the only exit.

Written for Imposing Sovereigns III.

Have a helping of Princess Cadance and Integrity.

Or alternately, Shining Armor and Justice.

This story is a sequel to Something Sweet to Bite Too

Sunset Shimmer hasn't been sleeping well lately. She doesn't remember her dreams very well when she wakes, but what she does remember is always the same.
She's back in Equestria. Only Equestria is very different from how she left it. The Palace is deserted. The land is a bizarre, twisted, candy coated version of what she remembers. The night never seems to end. And there's something in the dark... Something that laughs and sings, but it's somehow more frightening than the bizarre landscape ever could be.
When Sunset is awake, it's the start of a new year at CHS. The Fall Formal is just around the corner, but she has other things on her mind. Will she discover the truth about her dreams? Or will Halloween bring with it tricks and treats that make her Nightmare Night memories seem pleasant by comparison?
