As GM, the vampire is currently purchasing the Masquerade V5 Corebook and the two books Camarilla and Anarchs. I use them to create an environment in a city that I like very much: Grenoble (France), which I will use with my player.
I would like to know if this attitude regarding the tradition is plausible / how much it is not. Since I will not copy everything I write (to ask a question that is a question and not a novel), I'll just show you the summary.
Grenoble was ruled by a powerful tremor, Antoine Rousseau, a childe of Goratrix. He disapproved of the Tremere clan on most issues, but most of all with blood-burning clan members and the fact of keeping knowledge to themselves. Rousseau goes away and makes Grenoble his home, then announces that the city is open to all and that knowledge can be learned from anyone.
The power of Rousseau forces sect members to respect his rules, which are most likely to resemble the Camarilla tradition (replace "elders" with "the baron" and you understand it), even though he adds that blood ties and other mental dominance are illegal Vampires, and so the city was neutral. He was mostly the baron forever, sometimes giving the role to someone else, but sooner or later he got it back.
After the Banu-Haqim enter the Camarilla, the sect decides to use it to first introduce the city to the SI and then attack it to gain knowledge and strategic territory. The city was quickly taken and Chadia Rabah, a Banu Haqim, diabolized Antoine Rousseau, who was protected by a blood ritual that prevents her soul from being changed by the tremors. However, anarch and part of the Sabbath secured the knowledge of the majors and hide it in a place known to a handful of vampires, all of whom have now disappeared, whether they fled the city or Camarilla or the SI were killed.
As a reward for her murder, Chadia Rabah is now the Prince of Grenoble, naming Banu Haqim in a position where diabolization is no big deal.
Today, the city is in a cold war between the Camarilla and two Anarchist factions, Rousseauists (anarchists who want to do the city as they did in Rousseau's day) and innovators (anarches allied to a Sabbath member that is not in the Gehenna War gone) who want to go "true" Anarchs style (and somehow Sabbath style)
