[a reimagining and reversal of Blaze's "The Conversion Bureau".]

I'm sure you've heard all about it by now. Rainbows and sunshine. Unhappy humans turning into happy ponies. Dancing and singing together in harmony, now and forever.

All of those stories you've heard, exaggerated. All those statistics and graphs, faked. Propaganda. Delusions.

They didn't tell the real story, what it was actually like. So, I've decided to write this book to record some of the truths that have been... glossed over.

My name is Matthew Roberts, and I'm the Mayor of New Hope. While my covering may have changed, I am still human.
This is the untold story of the Conversion. The one they never wanted to acknowledge.

While the princesses of Equestria do a very good job keeping their land a peaceful and bright place, this does not mean that darker and more insidious forces do not exist.

In order to combat these powers, one must understand them, and Celestia has ensured that there is always at least one living pony in Canterlot who does. For the past several years that pony has been Pale Bones, aided by his assistant Scarlet Shade. They spend most of their time in a hidden archive beneath Canterlot's library, researching the dark underbelly of Equestria and the dangerous abilities its denizens wield.

One of Equestria's greatest traits is tolerance. Every pony, whether Unicorn, Pegasus, or Earth, is accepted for who they are, and have their own parts to play in keeping Equestria running.

But what if an Earth pony decided he didn't want to play his assigned part? What if he wanted to rise above everyone else and become an Alicorn? Such a thing is possible... but the path to fulfilling one's dreams is never simple. Risks must be taken. Sacrifices must be made. And the question is always asked: How far would you go to get what you wanted? And would you be willing to pay a terrible price to get it?

Ponyville is shaken to its core when a body is discovered in the Everfree Forest. As the townsponies grieve, the mysterious Special Agent Bentgrass from Their Majesties' Royal Investigative Service arrives at the Books and Branches library and drags Twilight into a world she's only read about: lies, corruption, suspicion, and murder.

Faced with an indifferent police force, and Agent Bentgrass's infuriating methods, Twilight must put the pieces together and catch the killer. But as blood continues to spill and questions pile up, one thing is terrifyingly clear: in the dark of the Everfree, much more is at play than mere murder.

So begins yet another chilly autumn in Equestria. While making her annual preparations for the winter, Twilight Sparkle comes across four jet black volumes in a dilapidated section of the Canterlot Archives. With Princess Luna's blessing, Twilight begins the long, arduous process of translating the ancient tomes. Before long, she begins experiencing horrifying dreams and visions of distant dimensions and indescribable monstrosities.

This is an attempt at blending the My Little Pony universe with Lovecraft's iconic cosmic horror.
Rated T for potential violence and nihilistic themes.

After being driven out of Ponyville following the incident with the Ursa, The Great and Powerful Trixie flees into the Everfree forest, where she meets a mysterious masked stallion named Herald. Herald offers Trixie a chance to learn ancient magic that will truly make her the most powerful unicorn in Equestria, by offering her a book that not even Twilight Sparkle has ever read. But there is a reason Twilight's never read this book, and there is more to Herald than there appears...

Twilight Sparkle stood on her hind legs, her forelegs to her side swaying back and forth as her scythe dropped to the ground. Tears welling up in her eyes, she looked down at the corpse that laid before her, still young, but ready to die. It wasn't her fault she was chosen for this, all because she became fascinated with new powers.

"I can't believe this."

Twilight stared over the horizon, gazing on the city of Ponyville in the distance. It's inhabitants, who once saw her as one of their best friends, now barely knew her. She could walk the streets to Sugar Cube Corner, or help her friend Applejack on the family's farm. She could even sit in her Library with Spike and read her favorite books.

But none of it would be the same.

"I am evil."

Some things are meant to remain secret; to forever toil in the shadows behind a smiling facade of playfulness and friendship. Rarity happens across such a secret one star-filled night, but can she steer towards the light, or with the intoxicating and seductive brew of power overcome her judgement? After all, that which should be feared the most is the friendly pony with the dagger behind their back.

There was only one explanation. For all of it. All of the strange, erratic behavior. Her irrational fear of the sun. Her nocturnal habits of locking herself in in the dark and closing all the blinds. Wearing her sunglasses everywhere, even inside! It was time to invest in some silver, garlic, and a wooden stake.
