Stories of ''Incubus'' and ''Succubus'' can be traced back to Ancient Mesopotamia. The myths carried well into The Middle Ages (and even into The Victorian Era). What is known of these demons is that they take the form of a seductive man or woman. They will drain a victim of their energy or youth until they are dead or well old for their age. Said to be from Hell, a person can become a Incubus (male) or Succubus (female), if one led an over sexualized lifestyle or gave into perversions. Upon death, their damnation was be to be reborn as one of these demons. Some tales link them to offspring of Lilith, Mother of All Monsters. Other legends have Incubus and Succubus turning themselves into old men or women, as a way of hiding their true appearance from the real World. They are only able to be stopped by abstaining from carnal and improper practices . Exorcism is not always effective.
