Well, firstly, on the communications front, I'd say the Lancea and Inv ictus have fairly solid communication networks; all those computer and phone thingymajigs, after all. The Carthians have the whole fragmented nature, whilst the Crones really are singular. The Ordo I imagine being somewhere in between a good network and a very very loose one, as above; they keep in touch and have a clan wide consensus and all that jazz, but it's not pushed that hard. As for inter-city relations, say between two Sanctified cities...let's create a quick example. Rome, with a small, isolated group of Sanctified as the "rulers" of what parts of the city that aren't under the Dominion; and Naples, with a roaring nightlife, healthily preyed on by vampires under the aegis of the ruling Lancea. Now, whilst Rome is numerically weaker and strategically disadvantaged, they are tightly knit behind the Lancea; Naples is not as well organized. So who swings more power, and how do they use it? As inter-city politics in general, Naples has the clear advantage, apparently, but their rulers are in some ways outmaneuvered by their rivals being better organized - and also having the prestige of living in Rome (if, indeed, it is considered prestigious; perhaps it is seen as disgraceful they've been forced back). I see the covenant as being roughly loyal to the overall hierachy, but between themselves, feeling it'd be oh so much better for both cities if they were unified - under the leadership of the vampire discussing the feeling, of course. Now how would the Prince of Rome use his superior organization of Sanctified to swing things his way? He might use it to suppress backlash after an assassination, for instance; but in the context of the quite organized, quite restrained and self-protecting Lance of Longinus, he probably wouldn't stoop so low. To out the Prince of Naples as a heretic (due to his approving a Circle festivale)...THAT is a plan. Of course, how the Italian Lancea interact with the downtrodden Jerusalem Lancea, or the schismatic Avignon Lancea and their fellow Gallicans...that's a further question of how well Milan, Naples and Rome can work together when faced with Paris and Avignon.
