Moving about thirty feet the party comes to another chamber, this one slightly larger than the last. Air pressure pushes their torch's flames back a bit, and Vonnn can make out a bit of colder air welling from a hole in the floor, near the southern edge of the irregularly-shaped room.
Occassional scuffs and tracks continue to be seen in the tunnel leading to the new chamber, and as the torchlight illuminates the entire room the companions can see that there is an iron spike sunk into the floor of the place, with a rope leading down, into the 5' x 10' sinkhole.
Animal tracks circuscribe the sinkhole, and can also be seen to move to the east, where the tunnel continues onwards. The ceiling of the chamber is low, only about eight feet high, and there ae small stalactites that hang down here and there, obscuring the adventurers' vision just slightly. Wetter than the last room, water drips down from the stalactites and funnels down the sinkhole (just a trickle).
