It has been a few months since Twilight and her friends went to help save the Crystal Empire, and Twilight had to use dark magic to find the Heart. And ever since she got back, Twilight's been acting strange spending most of her time muttering to herself, hearing voices, and locking herself up in her now 'off limits' lab basement.

P.S. seeing how many corrupted twilight fics there are, I'm sorry if anything I write is from your stories.

After being hassled by her friends while trying to do some work, Twilight calls out she wished she never came to Ponyville. Then that night Luna uses her dreamwalking powers to show her just how things would have turned out.

After his violent defeat, the former tyrant King Sombra has managed to claw his way back from the land of the dead and has returned to Equestria to seek revenge on Princess Celestia and the Elements of Harmony. However, the Emperor of Darkness is no fool. He knows that he cannot simply seek retribution on the Main Six or the Princess of Day, so he waits, gathering intel on his foes, learning of their weaknesses. When the time is right, he will strike. Can our heroes overcome King Sombra's plot for vengeance?

Sequel: The Return of the King

*Note: This story takes place in my official headcanon universe, not in the one for Shattering a Heart of Darkness

Following the return of the Crystal Empire, Twilight begins some intensive research into the history of the Empire and its late king. Modern historians know next to nothing about the enigmatic dark mage. Who was he? Did he have family? Loved ones?

The answers to those questions changes everything the Element of Magic knows about herself, and in doing so catches the attention of a shadow that yet clings to the frailty of life...

There, he waits for his chance to take revenge against Princess Celestia and conquer Equestria, though his affection for both his long-lost daughter and the mare that he loves have him question everything that he knows. Can the shadow-pony learn forgiveness and mercy or will he let his deep-seated anger and desire for vengeance consume him?
