The princesses gave their magic to Twilight to prevent Tirek from stealing it. As a result, they end up stuck in Tartarus.

Marvelous place, Tartarus. Really brings ponies together. The fact that things manage to go downhill here says a lot about the wonders of family and alicornhood.

We love the show My Little Pony: Friendship is Magic. That much we already know. The land of Equestria is full of harmony and more magic than we can ever dream of. But what if it was all a hoax? Is it really just a story somebody conjured up? Or is there a truth behind the truth?

A 200 Watcher Special. Thank You everypony who stuck by me these past few months. They were truly one of the best moments of my life. Enjoy!

Other Tag is for all the other characters in the story. There is simply too much to list in my opinion.

Twilight went to sleep with everything being fine. When she woke up, she would come face to face with Sombra once more, but this time, he has an offer. One she would love to refuse. If only she could.

The humans at the restaurant Freddy Fazbear's are getting tired of having to replace the night guard every week, and go to Canterlot to ask for Princess Luna's help. She agrees to help, but the animatronics aren't expecting a blue alicorn princess to replace last week's guard. Needless to say, they are caught off guard.

A thousand years ago, Princess Celestia banished her sister to the moon, that much we know. What wasn’t known, and what Celestia kept secret was that before her banishment, Luna had given birth to a foal. Now a thousand years later, as Nightmare returns to Equestria to bring about Eternal Night.

Twilight Sparkle, protege of Princess Celestia, struggles against the tyranny of this ancient foe. But how will she be able to save herself and her friends when the truth of this ancient legend crashes down upon her? Twilight will have to confront herself...and her heritage.

Twilight and Dash, upon discovering that the long awaited "Daring Doo 4" movie contains, eugh, Humans, decide to rent out A Nightmare Moon on Elm Street.

Of course all their friends are invited. There is absolutely no way any shenanigans could possibly ensue.

None.

Words and actions can sometimes hurt more than we know, sowing betrayal and hatred where friendship and innocence lies. A single thoughtless action can be a tipping point, one fallen domino setting off hundreds. Look back, and answer me.

Story theme is Chronophobia

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.
