The Origins of Vampirism

From the Book of Night onto Day ( NOD )

Eve was not the first woman that God made as a companion for Adam.

Before Eve, there was Lilith. She who was made the same way as Adam. She was not the submissive specimen that will yield to the demands of God and Adam. She questioned God and longed to claim her birth right. For that, she was casted out of the Garden of Eden.

Not long after, Adam and Eve were also casted out after eating from the Tree of Knowledge of Good and Evil. Eve bore Adam 2 sons- Canine and Abel. Both were given control over the land. Canine over the plants and Abel over the lifestock. Canine and Abel in turn had to give their their choicest crops and lifestock as a sacrifice to God. Canine's sacrifice was not looked upon positively as Caine's ability to grow and harvest them was born of God's curse upon Adam: that he should toil in the dust of the Earth. Abel's mastery over the animals came from God's gift of the same skill to Adam, and this made his sacrifice pure. Thus Abel was blessed over Canine.

Canine rebelled and murdered his brother in cold blood and flee the lands in fear of God's wrath.

It was during his time fleeing from God that Canine meet Lilith in the lands of Nod, east of Eden.

She gave Caine succor and showed him the power she had found, and Caine, desiring that power, fed on Lilith's blood to gain it. He then fled her house rather than battle her rage and continued his journey alone. Among his newfound powers were invincibility against Adam's descendants, great speed and strength, ability to manipulate time, shadows, flesh and mind; these powers would later evolve into the Disciplines which his children would wield, although with far less potency than Caine possessed.

At this point, Caine was visited by the archangels Michael, Uriel, and Gabriel, each in their turn and offering Caine salvation if he would but seek forgiveness from God for murdering his brother. Caine rejected each offer, feeling that God was a hypocrite and that he was the wronged party; enraged by his lack of humility and the bitter defiance he showed them and God, each angel cursed Caine:
Michael cursed Caine to forever fear fire;
Uriel cursed him to be unable to dwell in sunlight and to live forever in darkness;
Gabriel cursed him to be neither living nor dead, neither human nor beast, unchanging, undying and ever without hope; to feed upon blood alone; that hunger shall devour mercy; and that his offspring shall war with one another, young and weak against old and strong, that he may be their judge and know what it is for a father to condemn his children.
