I've been asked to run a second Dresden Files campaign, in addition to one I'm running set in Boston, for another group of players. I was considering the possibilities of using Las Vegas, and started wondering how this city would be different from my Boston setting, and from Harry's Chicago.
I'd like to make this a part of the same continuity as my Boston game.
The first thing that hit me was the mention in the rulebook that Vegas has poor barriers between our world and the Nevernever, probably because the city is considered to have less of a "soul" than other, more well-established cities. So there's probably a fair bit of activity from Nevernever predators. Summer Court is obvious as the ruling Fae Court.
Obviously, White Court vampires feeding on lust and especially despair would thrive in Vegas and probably have a major powerbase there. I also thought it might be a good place for the Reds to have a footing, controlling a number of companies and running financial scams.
Of course, this all raises the issue of the White Council. How would the Council feature in a city so heavily over-run by those who prey on mortals? The White Council they could probably leave alone for the sake of maintaining peace. But what about the Red Court? We don't have much information about the places in North America controlled by the Red Court. We'd have to assume that they were present in more places than just Chicago, but what's happened to them since the war started? Have they all fled? Or have some managed to hunker down and bury themselves too deep in densely inhabited areas for a safe yet effective attack?
