These ancient vampires, if they exist at all, are likely the most powerful creatures in the world. Members of the Third Generation, the Antediluvians are only two steps removed from the First Vampire, Caine. Antediluvians, when they choose to rise from their long sleep, affect all with whom they come in contact; according to the few fractured accounts of their doings, they possess virtually godlike power. According the Kindred legend, there were 13 original Antediluvians, though some have allegedly been destroyed. Their eternal struggle, the Jyhad, touches all Kindred, and innumerable layers of manipulation and deception make the plots of these Ancients almost imperceptible.
Methuselahs
If the Antediluvians are the Kindred's gods, the terrible Methuselahs are demigods and avatars. At a point between a vampire's thousandth and two thousandth year, a grave change overtakes the Kindred. Sometimes the change is physical, while at other times it is mental or emotional. Whatever the nature of the change, the end result is that the vampire no longer bears any semblance of humanity. Having truely moved from earthly into the realm of the supernatural, the Methuselahs often retire into the earth, where they may slumber awa from the thirsty fangs of younger vampires. Their powers are so great, however, they they continue to direct their inscrutable plans mentally, communicating magically or telepathically (and almost alway invisibly) with their minions.
Kindred greatly fear the Methuselahs, who are accorded any number of horrifying characteristics. Rumors speak of Methuselahs whose skin has become stone, of everything from hideous disfigurements to unearthly beauty that cannot be looked upon. Some are believed to drink only vampire blood, while others control the fates of entire nations from their cold tombs.
Elders
Elders are Kindred who have existed for hundreds of years, and typically range from sixth to eighth generation. With centuries of accumulated cunning and a terrible thirst for power, elder Kindred are the most physically active participants in the Jyhad - they do not suffer the long fits of torpor that hamper the Methuselahs and Antediluvians, but they are not so powerless or easily manupulated as the younger Kindred are. The term "elder" itself is a bit subjective; a Kindred who qualifies as an elder in the New World might be just another Ancilla in Europe or older corners of the Earth. Elders keep a stranglehold on the Kindred power structure, preventing younger vampires from attaining positions of influence by exercising control they have maintained for decades, if not centuries.
Ancillae
Ancillae are relatively young vampires (between one and two hundred years of unlife) who have proved themselves as valuable members of Kindred Society. Ancillae are the lackeys to greater Kindred, and - if they're clever or lucky - tomorrow's elders. Ancilla is the rank between neonate and elder, signifying that the Kindred has cut her teeth (so to speak), but lacks the age and experience to become a true master of the Jyhad. Because the world's population has grown so in the last two centuries, the vast majority of vampires are ancillae or neonates.
Neonates
Neonates vary from newly released fledglings to indolent Kindred of a hundred years or more. Marked by the stigma of not yet having proved themselves to the elders, neonates are inexperienced vampires who might one night make something of themselves- but, more likely, will fall as pawns in the schemes of the other undead.
Fledglings
Also known more loosely are "childer" (although every vampire except Caine is someone's childe), fledglings are newly reborn vampires still under the tutelage and protection of their sires, the vampires who created them. Fledglings are not considered full members of Kindred society and are often treated disrespectfully or as the sire's property. When her sire decides her childe is ready, the fledgling may become a neonate, subject to the prince's approval.
