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.

Darkness is a living thing. It consumes the strong and destroys the weak, not knowing the meaning of mercy. It corrupts and devours until there is no light left within one's heart.

What happens when the young mare who wields the Element of Magic succumbs to the Darkness?

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.

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...

Part 1 of the Shadow Trilogy

As Twilight Sparkle enters her third year amongst her friends in Ponyville, she finds herself plagued with strange dreams of an unknown power whispering dark secrets to her. The voices speak of Power, of the strength to protect what she holds most dear, of the great knowledge she could attain, such that no force could ever threaten her lands, or her friends, ever again.

Though she shrinks from this voice, the lure of greater knowledge, of magical power far beyond what she currently knows is enticing and alluring to her, eating away at her resolve even as the lack of rest begins to wear her physical defenses down.

What is this voice, and what does it plan for the most faithful student in Equestria?
