"Oi, they be wakin" A gruff heavily accented dwarvish voice. "I tollya they'd nae throw dead 'uns down 'ere."

One by one you are untied and set loose by strong, heavily calloused, not very gentle hands. Off pops the smothering sacks and you see where you've ended up.

The room is constructed of wooden walls, floor, and ceiling. Several areas of the wall have been torn down to reveal average, but solid, stonework behind the wood. The floor is in reasonably good condition save for a few holes that open directly onto dirt and rock. The ceiling is a good 12 feet up from the floor and there is no ladder or staircase visible. There is a trap door in one corner of the prison room ceiling and a refuse pit in the opposite corner.
The air is fairly warm, there is a faint smell of fire from up above. While there are no shackles or restraints, there is also no apparent way out aside from the trap door in the ceiling. The trap door is not close enough to the wall to make it easy to climb up using holes in the wooden wall planks, but it might be possible for a skilled acrobat.
In total, there are two warforged, one shifter, three humans, one halfling, and one dwarf. It's a little cramped for all the company, but at least you're not dead and the bag is off your head.
