They call me the marked one. . . I am a S.T.A.L.K.E.R. and I will be the one telling this story from my view. Long story short, I was killed by a mutant and sent to a world filled with humanoid ponies, but not a peaceful one. You see a pony called Twilight Sparkle was corrupted by a pony called King Sombra and now his Queen. She has gained a lot of power from learning Dark Magic and Blood Magic, so what does she do with it. . . murdered a Princess named Celestia. Yet even though her sister escaped and now is the riser of the sun and moon, the elements of harmony were corrupted as well but they have there own little empires. Shall I give a general view of what each ones evil purpose is?

Twilight Sparkle: Slavery
Applejack: Genocide
Rarity Belle: Vampirism (A empire of vampires)
Rainbow Dash: Dictator
Pinkamena Diane Pie: Cannibalism

The reason the one called Fluttershy is not this list is due to she stuck to her element. Now she and Luna wonder the world looking for a way to revers this. The only thing I question is "Why did I haft to get sent to a sexual one?!"
