*EDIT: I am cancelling this story, as I am losing interest in the MLP series as a whole. Basically, I have lost interest in my story, as well as the show. I am sorry if you were expecting more chapters.*

Some ponies just don't have any luck.

Twilight Sparkle is one of them.

Sure, other ponies might say she's the luckiest pony ever, being the personal protégé of Celestia, a well known pony in all of Equestria.

What they don't know, Twilight Sparkle isn't Twilight Sparkle.

Everything was perfect, her cover has never been blown. Until that one fateful day, the day Shining Armor, Twilight's brother, should have been married, the day of the changeling invasion.

The cleansing wave of love that send every changeling away...

There are only three ponies who know the truth, Twilight Velvet, Night Light and Twilight herself.

Twilight has just become an alicorn, a ruling Princess of Equestria. For a brief time, all seems well. But when both the reality of her new station and a dark secret behind Equestria's history finally confront her in full force, Twilight is forced to make decisions that could change the face of the Kingdom and ponykind forever. Now, nothing will stand between her, her friends, and finding the truth, not even the Princesses themselves. Alicorn Twilight cover art by Esipode.

After a long time letting it lay dormant, I've decided to give this story a complete reboot. Much of the original plot will be kept largely intact, but the focus has changed completely from the alicorn immortality itself to Twilight discovering its true nature and the history behind it. The clunky old wording and dialogue is being updated and improved as well.

Chrysalis is dying, and with her, the last of the Changeling race... but there might be a way to avoid extinction.

Twilight Sparkle never was a Unicorn and she didn't even know it.
What happens when her true heritage comes to light? Will she willingly embrace it? Or will she be forced to?

Beware of spoilers in the comments!

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.

After Luna's banishment to the moon, Princess Celestia swore to protect Luna's infant daughter, Princess Moonlight, and put her into an enchanted sleep only to awaken upon Luna's return.

A simple fairy tale, but one with dire consequences to the Mane Six... one in particular.

Everyone has their dark secrets or obsessions that they keep from the world, afraid that if anyone were to find out that they would be condemned and damned by society.

But what if your dark secret was one that involved taking lives?

Say hello to Twilight Sparkle, Equestria's favorite serial killer. Living by the code that her mentor devised for her, she takes the lives of those that destroy others and takes care of any who falls through the cracks of the justice system.

Life is good and it couldn't be better, at least until she is sent to Ponyville in an attempt for a normal life. She will make friends, enemies, and possibly find one that she may care for while satiating her dark urges.

But can she maintain a normal life without revealing her true nature? Or will she be caught and destroy the ones she will come to care about?

Can she have it all?

Twilight had been warned dark magic was dangerous. She thought she could handle it. Unfortunately dabbling in dark magic has left Twilight with a deadly disease that there does not seem to be a cure for. Will she succumb to the darkness, or will friendship and love be enough to make the remainder of her time happy?

Twilight didn't know what came over her. At one point, she was having a wonderful tea party with her friends, and the next thing she knew, she was trying to kill the princesses.
This could have something to do with the fact that nopony would listen to her at her brother's wedding, everypony thinking she is crazy, or even the fact that Discord was set free without anypony noticing.
She finds herself at Celestia's court, facing crimes she didn't commit.
"Twilight Sparkle, for stealing the Elements of Harmony, attempting to kill me and Princess Luna, and Betraying everything you were supposed to protect, you are hereby banished from Equestria, never to return!"
Celestia's words continued to ring in her ears as she followed the road out of Equestria. She would never see her friends again.
