Only Isthmus wolves have access to the entrance from the Web of Water. Covered in sand, this seemingly normal side of a sand dune is actually the hidden entrance to the StoneSayer's cave. The walls are sandy, but gradually grow smoother and whiter as the representative--or whatever wolf has been sent--moves on into the passage. Rather suddenly, the walls widen into a chamber, where the wolf/wolves can wait for the StoneSayer to appear.
