King Sombra survived his defeat, but just. By the time he returned to form, Twilight became the newest princess of Equestria and the Crystal Empire was restored to its former glory.

He cannot take over Equestria the same way he tried before, but he has a card up his sleeve. Twilight won't see it coming, and Sombra might gain a powerful ally in the process.

And it will all begin...with a book.

Love is the most sacred of magics, possessed by all but commanded by few. It is the driving force behind life in Equestria, the lifeblood of pony civilization.

But when a new kind of magic arrives in Equestria, it is up to its bearer, Twilight Sparkle, to decide its fate...
or perhaps it's up to the magic to decide hers.

Years have past since the changelings were driven away from Equestria, giving room for peace and love. Suddenly, Twilight is captured in the middle of the night, and is brought to the hooves of Queen Chrysalis. Seeing that she has captured the element of magic, she is determined to gain her revenge against both Twilight and anyone that has ever wronged her.

Using her dark magic, the queen transforms the unicorn into a horrifying creature. Will Twilight hold on to her sanity, and more importantly, her devotion to friends?

Or will she slip into the darkness, and lose all hope.

Props to chaos2012 for bringing me this idea. The story is mine though

Okay, new cover art! This time it was actually made for the fic, so credit goes to BronyInvestigator
I cannot thank him enough.

Magic, the most powerful of the Elements Of Harmony, it binds them together and helps keep stability over Equestria. Cut that off and what happens? What happens when the threads of friendship are severed, and the flames of chaos are rekindled? For Twilight, her existence's end is simply the beginning to something much bigger. How will she act in a world deprived of the harmony it once held as a creature that must thrive on the blood that Equestria has lost?

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 Sparkle has obtained the combined power of all four princesses of Equestria. Wielding this power, she confronts Lord Tirek, but the result of their fight is a tie. When he holds her friends hostage, she is forced to make a difficult choice.

All is not lost, however: one force remains in Equestria that could give her the edge she needs to defeat her foe, save her friends, and restore the world. She need only retrieve it from Zecora and place it around her neck...

In the aftermath of her battle against Tirek, Twilight Sparkle is unwell. She wants more. She needs more. And she is afraid of what others might think of her.

But even in the midst of her growing despair that she has betrayed everything she stood for, she learns something about friendship and what it means to be an alicorn.

A normal day was all it took.
A simple failed prototype, a missed experiment.
There was an explosion, and I woke up. I don't really know what happened between those two events, but I'm fairly certain I shouldn't have awoken in a small, dark box.

I'm scared.

Pinkie doesn't tell ponies about Pinkamena and Surprise. The doctors said that they were bad for her, that they were a disease, but she disagrees. Sure, Pinkamena's a bit of a grumpy-pants, but she's still a great friend! She's often the voice of reason to counter-act some of the other two's crazier ideas, after all. Surprise, on the other hand, is a great prank-player, and always up for some fun. She's more like Pinkie, only more hyper. Both are great fun to be around, and they get on well.

Thing is, she knows that if she told ponies about them, then they would be dragged back to the hospital. And then be 'treated' again. None of them want that. Because of this, not even her best not-in-head friends know about them. The three of them have, for years now, been careful enough to keep the existence of Pinkamena and Surprise secret.

This has, of course, gone out the window now that Twilight is hammering on the door after overhearing one third of a conversation, with no sign of anyone else talking.

Hints of F/F shipping inside. Nothing will actually come of it here, though. Maybe in a future story.
