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.
