A cobweb filled hall(ne and s)
This dank narrow passage has been cut from the living rock of the Erebor. The walls are dripping with moisture and are smoothed by the passage of time, though you can see the marks of toolwork easily enough. The floor seems a little uneven - it is certainly covered with dust. The whole passage is filled with cobwebs, and the way is quite narrow.
The only obvious exits are northeast and south.
