I'm thinking once we're done 'gathering' or preparing, we'll meet back up at the bar, then I'll do another expose of us heading out. The creatures we fight - when we get there - will be described, but it's not really so much like D&D persay (I don't want to be telling a story that you participate in), but more that stories can be created by all of us.
Take how I reacted to Nova's character. I hadn't planned on the town thinking there was a lizard in town, but just rolled with it.
