If Clan Lasombra is the heart of the Sabbat, Clan Tzimisce is the soul. Even other vampires grow uneasy around these flesh-crafting Kindred, and the clan's nickname of "Fiends" was given to it in nights past by horrified Kindred of other lines. The Tzimisce's signature Discipline of Vicissitude is the subject of particular dread; tales speak of crippling disfigurements inflicted on a whim, of ghastly "experiments" and tortures refined beyond human - or vampiric - comprehension or endurance.
