Lilith (evil spirit)

In Semitic lore, Lilith is a female evil spirit roaming in desolate places and attacking children; a demon (called a succubus) assuming female form to have sexual intercourse with men in their sleep. The succubus is the female counterpart of the male incubus, said to seduce women at night. In the plural form, these sex entities are called succubi or succubae and incubi.
