Vampire Bloodline Nosferatu Antitribu supposedly (according to Cainite historians) joined the Sabbat not because of their resentment for their elders but because of something more wicked beneath the clan's projected "public" image.
They seem to be on civil terms with the members of the main clan, but this is only because of things that are beyond their control.
Like the Nosferatus of the Camarilla, these antitribus are hideously deformed, cursed to eternal hiding or of agonizing others, in the case of Sabbat Nosferatus.
These antitribus spent their unlives in the sewers beneath their cities horrifying anyone who set foot on their underworld.
Many of these antitribus have a good time with their ugliness, using it to disgust both Cainites and Kine and like the Sabbat, they have thoroughly given up what human was left of them accepting their damnation and forever embracing it.
Mockingly, they remained the most humane of all the members of the Sabbat. Rising above the need pretentious brutality, the Sabbat Nosferatu got a grasp of the monster within.
They do not engage in senseless massacres, nor do they feast on blood, they perfectly know how to get the exact respond that they want with precise calculation from others, may it be fear, respect, or understanding.Most young Sabbats do not give the Nosferatu the respect that they deserve, they see the Nosferatus as "weaklings" 'till they set foot on the sewers and discover the true black souls of the ugly ducklings.
