Allu (AH-loo)

According to Akkadian mythology, this creature is in fact not entirely a vampire but rather is considered to be a CAMBION, a being that is half human and half demon. Described as being faceless, it is conceived when a SUCCUBUS has intercourse with a man. Assuming that the man survives his encounter with the succubus, as the time of his natural death draws near, his demonic son will return and linger at his bedside. Just as the father expires, the cambion snatches up the soul and enslaves it. Allu are particularly vicious and seek to destroy everything.
