I like to think of Faction as a fractal. The Night Faction will generally all have similar world views and interests and that may or may not mean that they also have goals and motives that align. As Paul Beakley says, it’s definitely not a monolith, but they’re more alike than they are different.

Then, you can zoom in and look at vampires and find the same thing. Then you can zoom further in and look at vampire lineages (or whatever term you want to use to talk about small or large groups). Then you can zoom in further and further until you get to an individual vampire (PC or NPC).

I like working with that framework because at the start of the game, I’m not going to know much about each Faction, but as we start to introduce more and more fiction, I can start filling in stuff at the appropriate fractal level and zoom in and out of my fractal as the story demands.
