I've had my eye on this for a while. How well-explored is the Vampire mob? Honestly, I watched the Godfather again recently, and I want to do something kind of mafia-esque with it. Perhaps at its lower levels it works like the Bratva, a brutal, Slavic gang, but at its higher levels it is more like the Costa Nostra with many customs and rituals, and more Latin/Italian influence. I'm thinking that the center of power for the Vampire mob originated in ancient Rome, and over time moved from Rome to Constantinople, and then to Moscow.
