Here is another romp through the cellars of the Moon Dragon Inn, this time aimed at novice characters (1st-4th level if you're using a level-based ruleset) who are asked to investigate after another customer mentions to the innkeeper that it looks like the storm cellar door has been broken into. This quite naturally alarms the innkeeper, one Bear Killer, as he's got lots of valuable stuff down there as well as a brewery and his ale supplies!
So it is a nice contained area for new-minted characters to investigate. There are traps a-plenty - Bear Killer has set them to keep folk away from his treasures, and warns anyone going downstairs even on legitimate business that if they see a 'Keep Out' sign it means just that! Assorted low-level monsters have indeed got in and are wandering around, so provided the characters stay in the parts they're supposed to visit, they ought to be able to gain valuable experience dealing with them.
Notes are provided on who has snuck in, with advice on making suitable selections from the monster books of your chosen system. There is also a page of details about Bear Killer's valuables should the characters ignore the 'Keep Out' signs, and the traps they'll risk should they be foolhardy enough to do so.
