The party heads west to fill in an unexplored area of the map. North of area 31 is a rubble-choked passageway. Our heroes scramble over the rubble and find an uninhabited cave.
In an alcove at the western end of the cave is a treasure chest! It resembles other treasure chests discovered on past adventures: hardwood, reinforced with iron bands. The stereotypical 'pirate treasure' chest, big enough to hold a hobbet (uncomfortably).
In this particular case the chest is locked with a sturdy iron padlock.
