Before I read this book, I knew very little about the Sabbat. From what little I could gather from various websites, it appeared to be a formalized gathering of anarchists, antitribu, Tzimisce, Lasombra, and other malcontents who chose to set themselves up as an opposition sect to the Camarilla. Masquerade? BAH! Kine are food. Allow your hunger to run rampant through the streets of the mortal world. Who cares? Gehenna is approaching and we must prepare ourselves for the coming battle. Ok. This book is much more than that. It outlines a much more involved code, rituals, and sociology. The Vaulderie and Vinculum bonds that result from it ... illustrate a genuine sense of vampiric camaraderie that may be imposed in the beginning, but that allows for disparate individuals to coalesce into efficient operatives dedicated to a mutual cause and immediate goal. In many ways the Sabbat is portrayed as a coalition of Cainite revolutionaries espousing understandably "human" traits, such as strength, loyalty, cooperation, and in some ways .... equity and order. They just approach things from a different perspective than the Camarilla. I agree with other reviewers who state that this book will provide more depth and dimension to the Sabbat, and if you roleplay and wish to start a Sword of Caine character - this is a resource you absolutely must acquire!
