Ok, as I'm working on a few things, including a setting, I figured I'd post something, you know, so there's actually some activity here... Brainstorming GM's prompt: the party of adventurers is hanging out at the tavern, as usual, between adventurers, and as it's after Last Call, most of the patrons have either already left or headed up to bed. The PCs are about to do likewise, when there's a pounding on the door to the tavern... What's causing it?
