After the most important night of her career is ruined and its saboteurs not even so much as punished, Octavia's life changes. She begins to pursue a path that has never been seen before in Canterlot, where concertos and rhapsodies give way to controversy and rebellion.

A path where symphonies are composed with cans of spray paint.

Bioshock meets MLP in this psychological thriller, where Celestia's new faithful student, Siren Song, must discover the truth behind the city beneath the waves.

Beautiful, gifted, and faithful student of the Princess of the Sun, Siren Song has very nearly everything a pony could want. Sometimes though, in the twilight hours, Siren can see the sadness in her mentor's eyes. Once, ponies whisper, the Princess had another student named Twilight Sparkle, but she left Equestria, never to return. The pony who has a perfect life just needs one more thing—to convince Twilight Sparkle to come home so the Princess will smile again. But when Siren arrives in pursuit of Twilight, she soon finds herself trapped in a city of horrors, with only its monstrous denizens for help.

Now with a TV Tropes page!

Down a well-traveled side street off the lower Las Pegasus market, stands a proud building with a dignified brass plaque on the door that simply says "The Sex Shop." Everypony's heard rumors of what's inside.

"...The test ends when you open that door."

Princess Luna has begun searching for her own personal student, and her test has hit a small snag: Not a single unicorn, out of the dozens of applicants, has passed. In fact, every last candidate has failed the test in seconds.

But just what is the purpose of this test? And how can somepony pass it?

A young earth pony named Morning Glory is going to find out.

This story is a sequel to What Have You Done?

Chrysalis, the Changeling Queen, has taken her prize, unhindered by Equestria's precious heroes. Celestia is little more than another prisoner of war now. The Bearers of the Elements of Harmony are lost, and the Elements themselves have turned away from Equestria's plight. As the world they once knew begins to crumble, a single question is asked among the people as they look up at their fallen heroes.

There is no such thing as "miserably ever after," for someone will always be fighting for things to change. Hope doesn't die just because someone's turned off the lights. Truth doesn't vanish when deceit begins its reign, and Harmony can only shine brighter among chaos.
Even as this world falls, we'll work to build it up again.
Even as you lose yourself, you can find greater things within you.
Even as fear rises up like a tidal wave, we'll forge a sanctuary to stand against it.
Even as you break, someone will always be standing there next to you to carry you through it.

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.

Twilight and Shining Armor have a little sister named Light Step. Everypony tells Light Step how lucky she is to be related to such great heroes.

Light Step wishes she could smother them both.

This story is a sequel to Detente

Discord takes Fluttershy to see something chaotic he's made that he thinks will be considered harmless and beautiful -- rain made out of light. Fluttershy agrees, but fears that ponies won't accept it anyway. They discuss friendship, and Fluttershy comes to some unwanted conclusions regarding her own feelings. One-sided, mild Fluttercord.

This story is the bridge between Princess Twilight Sparkle Endcaps and Elements of Opposition. To those who have not read the story before, and who like happy endings: don't read the second chapter. It leads directly into Elements of Opposition, and is the main reason the story has a "Sad" tag.

Edited to add cover art. Woo-hoo! The artwork for the cover comes from the wonderful C-Puff, goddess of adorable Fluttershy & Discord friendshipping. :-)

Set only a week after the banishment of Princess Luna to the moon, the realm of Equestria is in a state of upheaval. Celestia's royal guard attempt to regain control over the vast empire once ruled by dual monarchs, and the young alicorn's actions as a ruler have become a subject of scrutiny after her sister's attempted coup. Two factions have risen in the turmoil: The Knights of the Sun and The Bright Moon.

Far away from the political infighting and sword rattling exists a small mining town on the outskirts of Equestrian territory. Where once the royal guard would have no trouble fending off raids from bandits or other criminals, the panic of the capitol has caused a withdrawal of military forces to more essential cities and trading ports. Completely undefended and without a spell or sword amongst them, this town was soon overrun by a band of bi-pedal canines calling themselves the Diamond Dogs. As brutal as they are lazy, the Diamond Dogs have forced the local population to work until collapse to collect gems from the town mine.

Outraged by his inability to fend off these bandits and thieves, a young unicorn named Bone Marrow tries with all of his might to find his purpose in life - his cutie mark - and hopes that it will be enough to drive off the invaders of his home. He will soon discover that his special talent is far more than he bargained for.

((A Sequel will begin for this story as soon as I finish I Am a Pet Changeling. Stay tuned on Discord! https://discord.gg/nDXd3AB ))
