 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?" "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. 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. And I don't think there's another cargo rocket on this planet outside of the one we leased from the Club. "After Extrone said he'd hunt farn beasts, even if it meant going to the alien system?

"Of course you did," Extrone said, lazily tracing the crease of his sleeve with his forefinger. "Yes," Extrone said, "I imagine they are. Extrone's lip twisted in wry amusement. "If I had waited until it was safe for me to hunt on an alien planet, I would not have been able to find such an illustrious guide." "Of course," Extrone said. "Like all of my subjects," he waved his hand in a broad gesture, "the highest as well as the lowest slave, know me and love me.

 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.
