According to a midrash, Lilith was the first wife of Adam, his co-equal and counterpart in power and wisdom. She split from Adam Kadmon, and as punishment God (also known as Jehova) banished her from Eden, replacing her by making Eve. Furthermore, God cursed Lilith to never know the love of another. In turn each being that Lilith truly loved and cared for, could never really love her in return.
Lilith's worshippers claim that Adam attempted to rape Lilith — or he may have actually done so — which prompted Lilith to flee from Eden (some accounts claim that the child of this rape was Ennoia, the Antediluvian progenitor of the Gangrel, or even the first of the Lamia).
According to the Bahari, however, Lilith enjoyed an extensive sequence of affairs with both Yahweh and Lucifer, who were Gods with their own Gardens. Lucifer was said to have given Lilith the 'cloak of night' as a gift after she had wandered the lands outside of Eden, scorched and tortured. Eventually abandoned by both, she met the wandering banished descendant of her ex-husband, the First Murderer (as named in the Bible) Caine. She took Caine in, tended to his injuries, fed and healed him, and taught him secret wisdom — the seeds of which blossomed into the vampiric Disciplines.
And how does he repay her? By abandoning her as well, to wander forever apart, mother of monsters and thief of infant breaths. Caine goes on to found Enoch and Lilith leaves the scene.
