What truly had happened was that the primal beast of Rarity had hypnotized Fleur. The mare was brought down so deep that she was locked with her. It was something she had done to a prey before, but never as powerful as then. Myths would say that Fleur was chained to the grave in order to serve the vampony until she either got released or one of them died. Their minds were connected with each other. Rarity could give her any mental order and she would execute it. "I always win darling, and call me 'lady' from now on please," she spoke in a pleasurable yet dark manner.
