The three sneaky whelps make their way a few steps forward, where the cave bends to the left. Faint flickering light can be seen from further in and two voices discussing something in the language of the icemen can be heard.

A quick peek shows you the situation:

The cave widens about 5 steps beyond the bend. Three icemen guard a chamber big enough for 10 or more. One is seated on a rock to the left, the other two face each other directly in front of a tunnel leading off deeper into the hill. From the wolf warrior who escaped you know that there are two more tunnels, one left and one right.
