In the farthest corner of Equestria, an amateur researcher and practicing psychiatrist, who also happens to suffer from mental illness like delusional psychosis and paranoid schizophrenia, has become obsessed with the thought that, like Luna and Celestia being the physical manifestations of the spirits of Darkness and Light, Night and Day, a third spirit, the only force that can settle a conflict between the primal forces of Dark and Light, has also gained a physical manifestation into pony form. This researcher spent years of their life believing the physical form of the harmony spirit, the third spirit that only legend mentions of, to be a lavender alicorn pony living in Ponyville, and has dedicated their entire life to watching, studying and becoming completely obsessed with the pony known as Twilight Sparkle.

Having watched Twilight Sparkle, and her five ordinary Ponyville friends take on some of the most terrifying, evil beings ever to walk the earth, and seeing the mare achieve the impossible to become an alicorn, the creature has become convinced that this is more than just a supposed magic of friendship, and that this little alicorn is the manifestation of the third spirit: The Great Equal, as it has calls her.

The researcher has since been devising a plan to capture the mare, and uncover her true secrets for the world to see, and make history by being the one to tame and weaponize the spirit, and the beast it creates as its primal form.

Years of obsessive study of the alicorn have proven that the way to complete control of Twilight Sparkle's soul, is through the control of her precious friends. And then, the releasing of the primal beast within her would be done through an intense sexual torment. Or atleast, so the researcher believes... After all, the theory has proven successful on a particular test subject...
