Ardat Lili is a dangerous storm spirit from ancient Sumeria, a vampiric succubus who visits men at night. She inspires them to masturbate as she conceives other Demons from men’s nocturnal emissions. She is very ancient: surviving information is limited and unclear. She may be an ancient incarnation of Lilith, Lilith’s handmaiden, or a closely related spirit.
