Twilight wants to know. She wants knowledge. What scholar doesn't? So in order to gain some she starts looking into changeling magic. Which slowly leads her to the powers of dark magic.

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

I cannot thank him enough.

"Throughout my entire life I have faced many great enemies, but I never would have imagined that my greatest enemies were my closest friends. I mean, I invite them to my kingdom after ten years for what?! So they could bring me down?! No! It's them. It's their fault. It's their fault she's d...What am I supposed to do, Spike? We lost our closest friend because of those stupid ponies! They're all idiots! Princess Celestia and Princess Luna thought they knew how to rule their kingdom, well they forgot one very important thing: power! I need more." "Listen to yourself, Twili-" "Be still! It's Hysteria. Queen Hysteria. Princess Twilight was weak. With this power I will renew Equestria! Yes. I will build a better world!!!" The Queen then started singing to herself, "Feel that donation. Annihilation. The power of my words, kills any nation. Sweet degradation. Politics invasion. Give me the power, to save generation!"

Twilight Sparkle has failed at getting the Crystal Heart in time, letting the former king, who enslaved the entire kingdom over a thousand years before, return to take over the Empire.

Now, with the Crystal Heart permanently gone, Twilight is now bound to King Sombra for all eternity...

Because of this, it even left the only pony who can save her, her loved ones, and the empire, powerless against him.

Now with Dramatic Reading by ME!!!

There is only one real rule regarding changeling royalty: there must always be a queen. Twilight Sparkle is about to learn this through personal experience.

Originally written for an X Becomes a Changeling prompt almost three years ago.
Set after season three.

Twilight Sparkle finds herself spending time with a local pegasus from the weather team, and may be developing feelings for her.

But when they stumble across a relic of nightmares past, Twilight must learn to cope with distressing new urges, and keep her friends and the rest of Equestria in the dark...

Twilight Sparkle: magician, scholar, bearer of the element Magic, and most of all, friend.
A bat, a book, and a bite can change so much of that, and bring darkness to her heart.
Can you keep your friendships when you might hurt those around you?
If you want to hurt them?
Bloodlust can bring an end.

A lone vampire bat sneaks through the mirror portal and ends up in the human world. Instead of apples, it now craves something far richer. And unfortunately for Sunset Shimmer, she's its next snack.

Sunset can't remember any of her activities past sundown. The light hurts not just her eyes, but burns her skin. And she's thirsty.

So very thirsty.

It's up to the Rainbooms to save Sunset from herself before she drinks the whole city dry. Too bad Twilight Sparkle is her primary target.

Thanks to Saro0fd3monz for the inspiration!

Now with a TVTropes page!

Now with a French translation!

What if Spike had been home when Tirek destroyed the Golden Oaks Library, and had been killed? What would Twilight do? More importantly, who would be able to stand in her way and stop her when she delivers retribution to those who have caused her to lose everything? After she defeats Tirek in combat, she turns her focus on all of Equestria, and those whom she lays blame upon for the death of one she held dear to her.

With the combined powers of all the princesses inside of her, and a deep anger within her soul, can she be stopped, or will all of Equestria answer to her wrath?

Written for the Twirant's Kingdom Competition in the Tyrant Sparkle group.

Shortly after being crowned princess, Twilight wakes up to find a returned Nightmare. Though its new guise is familiar, it is unexpected. At least until Twilight walks the paths that lead to her friend standing at Nightmare's side for herself.

The GORE in this story is lite… but better safe than sorry, so I marked it.
