Renya follows Sindri, Jack, Angus and Keepiru. Her bow is traded for a pair of sharp knives.
The stairwell is the winding king of stone stairwell, and is quite tight and steep. The air is thick and hot here, and quiet enough that every breath is magnified in the ears of the breather, every foot step and rustle of equipment too close.
Jack seems to be almost too large to fit the stairwell, and as he descends he seems to be picking up more and more dusty cobwebs on his shoulders and hair. As his shoulders squeeze, they buff against numerous square holes in the walls. These holes are only six inches, and evenly spaced along the outer wall; where one isn't visible, cobwebs are covering them until Jack knocks them off.
Eventually the stairs open into a long hallway that moves into darkness. Far ahead there is a single red pinpoint of light.
