Thanks for the quick response!
I'm gearing (get it?) up to run the 4E version of the AP for my group, so you'll be seeing some more threads pop up with questions from me. After running the Shackled City AP a few years back, i haven't really had the urge to dive in to another long-term campaign, but Zeitgeist looks really, really great. We're in the process of finishing up characters currently, so we should be starting things up soon.
Keep up the good work!
