Hell's gate Vampires

These vampires are from the pits of what christians call hell. They don't feed on blood, or emotion, they feed on Destruction, not the emotion, the destruction they feed on is void of emotion, it is the knowledge that you do what is necessary. They feed on the nothingness that comes after the emotion is spent and gone, but they won't create the emotion, humans are emotional enough without them feeding negativity. They feed on the resolution to do it. They feed on determination but not human emotions; sadness, anger, bitter ect.., I hope I am making sense. 

They feed on revenge, not the revenge that is born out of emotion, the revenge that comes from the state of, it has to be done. They also feed on sex. This is the ONLY type of feeling they feed from. They will induce an orgasm and they will feed on every single ounce of pleasure you get from the time you pull your clothes off, till orgasm. It will make them stronger and their manifestations easier.
