In the pavilion, the business went briskly. Only the Hedarin, sitting aloof, seemed unfriendly. Their faces gave Trehearne a peculiar feeling. Rather too small for their massive heads, though not so much as to be deformed, their features had a sort of iron strength that was almost chilling, as though the mind behind them had overswayed all the weaknesses of the flesh. Their eyes, deep set and light in color, seemed to look inward, not in the usual foggy contemplative way of people pondering over their thoughts, but as down a bright, clear vista where nothing was dark or doubtful, where no trivia could exist, no stirrings of emotion, no wayward impulse. They were splendid looking men. He had to admire them. But there was no thought of liking them. They watched the trading, and Trehearne began to notice that every item was offered for their approval before any bargain was struck. Most often it was granted, but now and then there would be a shake of the head and the article was rejected. The merchants might look regretful, but they did not protest. "They swing an awful lot of weight," Trehearne said under his breath to Yann. The First Officer, a slightly greying man who knew the Cluster like his own flower garden, was standing near and heard him. "So would you," he said, "if you could look inside a man's head and see all his thoughts, and into his body and trace the course of every gut, simply by using the power of your own mind." "Uncomfortable people to have for rulers." "They don't rule, in that sense. They're the physicians, the judges, the scientists--purely intellectual, a separate caste. They wouldn't stoop to anything as physical as ruling. They live entirely in and for the mind. In temporal matters they merely advise." Remembering a certain Dr. Rhine, Trehearne asked, "Can they do everything? I mean, teleportation, telekinesis, telepathy, all the tricks?" "They never discussed it with me, but I should think they could do all that, and more." "Insolent bastards," said young Perri, scowling. His Vardda pride was hurt. Rohan kicked him. "Keep it to yourself. And don't even think too loud." Trehearne fidgeted. For the moment there was nothing to do, and he was standing with the others, six or seven of them, waiting. Finally he whispered, "What do we get here that makes it worth while?" "Gem-stones," said Yann. "Fabulous. And their lapidaries rank as just about the best in the galaxy." He bent his head very close to Trehearne's and whispered, "All the same, I agree with Perri. Look at those merchants. Damned if I'd let anybody tell me what I could buy, and what I couldn't."
