A new stranger enters the prehistoric world in "The Conqueror." He turns out to be a fugitive from his people, after trying to conquer all the tribes on the plains outside of Lost Valley. Now, he turns the cave people against one another, after Turok had worked so diligently to forge peace. Then, Turok and Andar raft to an island made of chalk in "Perilous Voyage." The people living there have no stone to make weapons with, and so cannot hunt for food, instead gathering nuts and pteranodon eggs for sustenance. The Indians decide to lead them back across the dangerous water, back to the land where there is stone to make weapons.
