And Scott went sick with understanding. Through rigid lips, he forced the words: "Energy-eaters!"

The Captain laughed oddly. "And you wondered how they lived on this naked rock. They ate the raw ore, of course. No wonder they hung around Durval's machines sucking up what free energy they could. They broke through the air feeder system here. No wonder. With cells of 80% pure uranium waiting for them." His voice broke.

"So we're finished," he continued. "The Kastil will be loaded before we can even clean the cats out. We're done."
