Lilith's children on Earth originally accounted for all manner of nightmares.
Increasingly, in popular culture, these monsters in general have started to come into a sharper focus. The devouring of humans has become the sucking of blood or imbibing of life-force. Lilith's line is vampiric.
This legend explains why some human beings are locked out of Heaven after death. God wants nothing to do with them. Jesus died for Adam and Eve's line only.
Thus Lilith's descendants are doomed to join the ranks of the Undead, rising from their coffins to plague the living. They are the vampires of myth and legend; even those whose genealogy is so diluted, that they do not know that they are descended from Lilith. They thought they came from Eve.
It's a story embraced by writers of vampire fiction, including a notable appearance in the fifth season of True Blood (as pictured above). But it's not a retelling which has gained much credence amongst serious religious scholars.
Then again, the whole Lilith legend is not one with much of a foot-hold in mainstream Judaism, Christianity or Islam. She exists on the outskirts, her story dismissed by some as the dodgy ravings of a 10th century writer of Jewish apocrypha. To them, she was not air-brushed from the Creation story. She was never in it.
The serpent was just a serpent. The Deluge was a show of divine might, designed to discourage evil amidst humanity. The figure spotted in the ruins of Edom was just one of those random insertions for which we've lost all context. Perhaps some kind of animal. A snake.
It's only as a vampire that Lilith takes flight now. Still feasting on children, spreading disease, unleashing her demonic host in defiance of God's dominion. It's been a long war that she's wrought against the constraints of Eden. Adam should have let her go on top.
