Hmmm.... I'll remember the silence. Seems like a good idea. I don't know about playing out side. By the time it's dark enough it'll be a little too cold for people. I may try out the candles though. Got a really creepy, leafless, black, stylized iron-tree candelabra from Prague that'll look really great for the mood.
Didn't realize I'd need too many playable NPCs. I'll make sure to do so, though. It's always good to be prepared. After my Ravenloft campaign, I've gotten pretty used to fudging monster statistics for atmosphere. Doesn't look like it'll be too hard with the d20 version of CoC.
