You already had me covered ok.
What about deities and temples? Religion for Vampires would be important ( and its something that I think would be pushed upon with all this Roman-vibe in a modern world.
Are Vampires ak nown thing? Like does your average Joe Human known about his Vampire neighbors. down the way?
Are there Blood Bank for Vampires? So they can get food, and the 'cleaner' vampire blood can be parceled out for healing purposes ( I assume it must adapt to the 'hosts' body, but can be stripped of any of the 'extreme' vampire properties, so they're not making new vampires.
