We're calling the Feet-in-the-Water sub-campaign the 'Street' campaign and the Submerged sub-campaign we're calling the 'City' campaign (not creative, but it works).
The final story arc will switch back and forth between the two groups more rapidly for the final climax of the overarching campaign. The two campaigns are happening concurrently and there will be significant overlap between them (with each explaining or expanding on things that are left mysterious in the the other). The same players are involved in both groups and we're switching back and forth between complete stories (we're expecting 3-5 sessions per story). We're running two separate sub-campaigns with two sets of characters (a group at the 'Feet-in-the-Water' power level and one at the 'Submerged' level). I'm using Obsidian Portal for the adventure log and the campaign notes (you can check out the campaign site here).
We're running a campaign in Las Vegas based primarily around shutting down an Outsider trafficking ring (several elements were inspired by Harry Connolly's Twenty Palaces series, though that will be more apparent in future sessions). I finished writing up the first set of actual play reports for our ongoing Dresden Files campaign and decided I'd post them here.
