The floor they're on gives way to an area where the ceiling has collapsed, with only charred rafters providing access to the opposite side of the hole. Below, the room opens up into another floorless chamber, leaving a narrow, charred ledge along the south and east walls, while to the northwest, a ledge heaped with crates and barrels sits, a pair of goblins, armed with heavy crossbows, obviously designed for someone larger than them, wait in ambush for anyone coming through the door on the lower floor.
