The first son of Adam and Eve, Kaiyne was cursed by God to be immortal and to never find rest. In Damnation, this means Kaiyne can never feel satisfied and will never find peace. As an immortal, Kaiyne built the first city, a metropolis described as being much like New York city. In the Testamentum, a Dark Stranger came to the city and injured Lamech who in turn, killed him. Kaiyne stood up for his offspring and others from the First Brood came looking for their brother. When Kaiyne attempted to turn them away, a war broke out. The offspring of Kaiyne defeated the First Brood, inheriting vampirism. The First came to the city seeking out his offspring. When Kaiyne explained what had taken place, The First blessed his offspring, giving each their Dark Gifts to master.
