Minor issue: you mentioned that the di Marcianos have some brothels, but unless they are the same people as the Arbor family (in which case, they are a bit more benevolent than depicted, at least in my mind) or they quietly declared war on the Arbor family.

I see the Arbor family as being, as a whole, solidly CN. They do have to kill occasionally to protect themselves, of course, but the district prospers under their rule and the city enjoys the district.
