The Sabbat (Suh-baht) is a loose organization of Cainites who reject the Traditions. Unlike the Camarilla, the Sabbat believe in the Antediluvians and Caine. Also known as the Sword of Caine, as they believe they will be the army Caine will use to destroy the Antediluvians once Gehenna (the end of the world) arrives.
The Sabbat was founded in 1493, largely in reaction to the Convention of Thorns which founded the Camarilla. They are the remnants of the Anarch Revolt of the time. Leaders of the endeavour were the Tzimisce and the Lasombra, two Clans that had ostensibly destroyed their Antediluvian founders and had accepted that there was no turning back for them. Delegations of both Clans met at the island of Mallorca and began their own negotiations, aided by several malcontents among the Anarchs, who refused to surrender to the Elders or did not share the view of their main Clan. Others joined to escape the practice of the Blood Bond. These groups existed as small packs in the wilderness that harassed the holdings of the Elders and those who had submitted to the Camarilla, called "Sabbats" by the superstitious mortal population for their rapacious behavior and proud display of their inhumanity. Slowly, these disparate packs were brought to heel by the spreading of the Vaulderie, uniting the remnants of the Anarch Revolt as the Sabbat, a sect devoted to warfare against the Antediluvians and the tyranny of the elders.
The Sabbat sees itself as the army of Caine and consequently is tightly organized, far more than the relatively anarchic Camarilla. The Sabbat consists mainly of Clans Tzimisce and Lasombra and numerous antitribu from Clans normally independent or associated with the Camarilla. The cornerstone of Sabbat organization is the pack; Sabbat packs are organizations of 3-10 vampires mutually bound through the standard blood-sharing rites of the cult. Packs have a ductus, who is the pack's warleader, and a pack priest who reminds the pack of its responsibilities to Caine. In addition, pack members are mutually bound in a vinculum — a sort of communal blood bond — created by the blood-sharing ceremonies. Packs generally occupy communal havens; given the Sabbat's rejection of human mores and its use of artificial loyalties enforced by the vinculum, there is less need for privacy.
