These caves take up part of the tunnels beneath the Falcon-clan city of Tûr Morva, serving as dungeons and storage for the Hebog-lûth. The tunnels also extend deeper into the mountains along paths known best to the Falcon-clan. Within the caves is a pit that is home to a large beast and into which prisoners are sometimes cast.
The caves can be entered freely before Instance: The Captive, but you cannot go far into them. They are locked afterwards when Tûr Morva becomes hostile.
