Social Castes Among Cainites
Cainites are divided into several different castes. They are generally distinguished by age and how far one is removed from the blood Caine.
Caitiff -- Most Caitiff are Clanless but otherwise "normal" vampires, others have become so degenerate that they feed only off the weak and dying. Some Caitiff live apart from vampire society on purpose, but many have been cast out. Some Caitiff were once a part of Kindred society, but have lost so much humanity that they are unable to maintain relations with any other creatures. They know only survival, and live from night to niht in search of food.
Childe -- Vampires of this class have not yet been introduced to the prince, nor have they been released by their sires. They are not considered to be full members of vampire society and are thus shown no respect. They are, in short, treated as children.
Neonate -- These vampires have been recently released and presented to the price, though they have not yet made their mark in their society. The neonate is the caste of youngest vampires who have been released by their sires.
Anarch -- The anarchs have status because they are noticed and respected for what little power they have achieved. They are recognized for their energy, drive, and consistency. Though they are the enemies of the elders and especially the prince, they are still respected, if not openly, for by rebelling they have given themselves an identity.
Ancilla -- These Kindred are still young, but have proven themselves to the elders. The ancillae are the up-and-comming Cainites, the ones who play by the rules (mostly) in order to achieve great power. This is the rank between neonate and elder, where the vampire is given increasing respect and power.
Elder -- When vampires reach a certain age, there are few above them who still hold power in vampire society. The elders are the Kindred who are in control and who seek to dominate all the others. In Europe, a vampire has to be much older and powerful to be considered an elder than he or she does in the New World.
Prince -- The Elder who holds domain over a specific metropolitan area is known as the Prince. A Prince holds power over the domain; he or she makes the laws and is responsible for keeping order.
Methuselah -- When a vampire reaches a particular age a profound change invariably overtakes them. Only the VERY stongest attain this station. As a means of self-preservation, they retreat from the world and those younger than them. Some Methuselahs remain involved in power stuggles and the Jyhad, but do so from complete anonymity.
Antediluvian -- These are the most ancient vampires and likely the most powerful creatures in the world. They are considered to be the grandchilder of Caine himself.
