Sabbat
Unlike Whitewolf's Camarilla, freedom is preached in accordance to the Sabbat belief that every vampire is free to create their own destiny without being hindered by the reputations of their elders, and that no Sabbat has to lay down their life for cowards who cannot take care of their own matters. Of course, it does not always work like this in practice.
Also unlike the Camarilla, the Sabbat believes in Antediluvians, and for the most part considers them a great threat. This is unsurprising, especially considering that the Sabbat was formed in the wake of the Anarch Revolt, and both of the core clans, the Tzimisce and Lasombra, claim that their clan founders were killed during this period of upheaval.
All Sabbat adhere to a code of conduct called "The Code of Milan", which preaches loyalty to sect and packmates, and to one's own freedom within the sect, as long as one's own good is never placed above the good of the Sabbat itself.
In addition to a very firm "if you're not with us, you're against us" mentality, the sect considers vampires to be a higher form of life than humanity, and is based upon the principles of Loyalty and Freedom. Loyalty to the sect and to one's comrades is one of the important aspects of the sect, and the Sabbat vampires maintain this loyalty through a ritual called Vaulderie, where strong emotional bonds are created between members of the Sabbat.
