 If Mia is wealthy enough to buy half the planet why is he Extrone's guide?
Of course using live bait is the best way to lure dangerous alien animals ... unless it turns out that you are the bait! Extrone asked, "Is there a pass?" Delicately, Extrone raised a hand to his beard. Right up ahead of us. "We'll pitch camp right here, then," Extrone said. He crossed to Mia, who, along with him, had been pressed into Extrone's party as guides. "At least, then, I wouldn't be one of his guides. "What hurts most, he pays us for it. I could buy half this planet, and he makes me his guide—at less than I pay my secretary." "You two scout ahead," Extrone said. "Yes, sir," Ri said, and instantly the two of them readjusted their shoulder straps and started off. The grass was beginning to grow again, but the tree stumps were roasted from the rocket breath. And I don't think there's another cargo rocket on this planet outside of the one we leased from the Club. "Everybody and his brother had heard the rumor that farn beasts were somewhere around here. "After Extrone said he'd hunt farn beasts, even if it meant going to the alien system? I didn't tell Extrone, if that's what you're thinking," Mia said. Too many people already know about the farn beasts. It was a military craft, from the outpost on the near moon, and forward, near the nose, there was the blazoned emblem of the Ninth Fleet. The rocket roared directly over Extrone's tent, turned slowly, spouting fuel expensively, and settled into the scrub forest, turning the vegetation beneath it sere by its blasts. Extrone sat on an upholstered stool before his tent and spat disgustedly and combed his beard with his blunt fingers. Shortly, from the direction of the rocket, a group of four high-ranking officers came out of the forest, heading toward him. Extrone demanded, ominously not raising his voice. Extrone's face looked much too innocent. "But, sir...." Extrone toyed with his beard. "You'll destroy this one, too," Extrone said. Extrone said, "To begin with, they probably don't even know I'm here. "That's why we'd like you to return to an inner planet, sir." Extrone plucked at his right ear lobe, half closing his eyes. "You'll lose a fleet before you'll dare let anything happen to me, gentlemen.
 Extrone is the sovereign, everyone must do as Extrone commands.
 Extrone threatened to kill Mia's family if Mia didn't act as his guide.  Extrone found out Mia had hunted farn beasts previously and demanded Mia act as his guide.  Extrone kidnapped Mia, and is forcing Mia to act as his guide.  Extrone is the sovereign, everyone must do as Extrone commands.
