Fading between Dream - Nightmare - and the Real world, Rarity discovers a dark desire innate to her soul... pain, to give it, to receive it. As it is woken up in her - as she becomes in tune with her dark desires, so do her friends take notice. Inspired by Lil Miss Rarity.

Join Rarity, Pinkie Pie, Twilight, The Mane Six, Pinkamina and Sweetie belle for a macabre adventure that delves into the very soul of Sadomasochism. Will the cheerful, happy-go-lucky world of Equestria be big enough for an unabashed Sadist, or will poor Dress Horse become ostracized from her very friends and closest relatives for her dark temptations?
