The Camarilla
It is much harder to grasp the motivations of The Anarch movement without first understanding the sect that they are actively subverting: The Camarilla. The Camarilla is, and has been, the defacto and ruling political body for Vampires in Europe since its foundation, almost seven hundred years ago. They are the puppeteers in the shadows, attempting to control mortal society from behind the scenes: all in the pursuit of ensuring the survival of themselves, and the elders to which they answer. A true propaganda marvel: members of the Camarilla are indoctrinated into a worldview dictated to them by their Elders. With the ban on technology in place, there is very little reason to believe otherwise, and contradicting those above you is often met with an iron fist.
In years past, the Anarchs and Camarilla were nominally aligned in the war against the Sabbat. An alliance of necessity, if nothing else: as the Anarchs were never truly powerful enough to deny this demand, and simply had to bend the knee to their oppressors. With the Sabbat gone, and The Second Inquisition barking at their doors; the Camarilla cut loose their ties with the Anarchs, declaring open war on their previous allies. Simply, the Elders saw them as too much of a threat to their safety, and the safety of their Masquerade.
Leaving The Camarilla is no small feat, and in turn, many are hunted down for doing so.
In recent years, The Camarilla have closed the doors to their Ivory Tower. They turn away any who are not deemed worthy by their standards - no Duskborn (or thin-bloods as they call them), no caitiff, none below the 13th generation, and no one of an Anarch persuasion. Theirs is an elitist, and strict, hierarchy. Hellbent on maintaining the order of things, as they have been for centuries. Only certain clans are permitted entry to their domains, and they will violently eliminate anyone caught trespassing.
