The Conversion Bureau is the most vital, exciting, controversial, and powerful subgenre of MLP:FIM fanfiction in existence. The Conversion Bureau stories had a humble beginning as a simple wish fulfillment story. It was not a particularly good start, but the idea encapsulated within it was one of the most powerful notions known to man - to illuminate the human condition through the creation of an Other to act as a mirror.
Since then, the many, many Conversion Bureau authors have expanded the original conceit - that an alien universe called Equestria breaks into our own cosmos and begins to irrevocably change the destiny of Mankind - in countless ways. Authors have sided with the alien ponies, or against them, used the scenario to explore the very depths of human emotion and experience, as well as to tell exciting and powerful stories of adventure and wonder.
Originating from the fantasy backdrop of My Little Pony: Friendship Is Magic, the Conversion Bureau stories have taken that world into the realms of science fantasy and even hard core science fiction. Stories comedic, dramatic, horrifying and filled with wonder and awe have derived from the premise of the Conversion Bureau.
Factions and enemies unique to the genre have been invented. Tropes and memes unique to it have arisen. The subgenre has inspired music, poetry, sculpture and more. Always controversial, always questioning, The Conversion Bureau without question is the home of the most intelligent and unusual writers that fanfiction has to offer. Vastly unappreciated by the mainstream of fanfiction readers, the Conversion Bureau stories are the crown jewel of pony stories, pushed aside because of their power to disturb and enlighten.
The many brave authors of this most magnificent of subgenres, who dare to write stories that thrill the soul and challenge the mind, dare to explore what it means to be human through the guise of ponies. They are determined to disturb you, the reader, to force you to think, to consider what being human means, what it is worth, and whether or not it truly is worth anything at all. Conversion Bureau stories are the bad boys, the dark horses of the fanfiction world, and in their curious texts I guarantee you will find both joy and anger, wisdom and fun, wonder and horror in equal measure.
