After crash-landing, he finds himself in the dry and barren wasteland of the planet Kerona, hunted by a spider-droid dispatched by the Sariens. Roger makes his way through the desert and a system of caves and is greeted by a mysterious disembodied head, he is tasked with killing a monstrous creature called Orat in exchange for transportation. After succeeding in this task and in the evasion of the hunter droid, he returns to the alien head with proof of his success in the form of a piece of Orat's flesh. As a reward, he is allowed into an underground complex inhabited by other aliens of the same species, and is provided with a skimmer, a small hovercraft (a direct reference to the landspeeders in "Star Wars").
