"The first thing you new men should understand," the Quaestor said, "is just exactly what you are. That's very important. And I'll tell you what you are. You're _peons_. You're the lowest of the low. You're _statusless_. There's nothing lower except mutants, and they aren't really human. Any questions?" The Quaestor waited. When there were no questions, he said, "I've defined what _you_ are. From that, we'll proceed to a basic understanding of what everybody else on Omega is. First of all, _everybody_ is more important than you; but some are more important than others. Next above you in rank is the Resident, who hardly counts for more than any of you, and then there's the Free Citizen. He wears a gray finger ring of status, and his clothes are black. He isn't important either, but he's much more important than you. With luck, some of you may become Free Citizens. "Next are the Privileged Classes, all distinguished by various recognition symbols according to rank--such as the golden earrings, for example, of the Hadji class. Eventually you'll learn all the marks and prerogatives of the various ranks and degrees. I might also mention the priests. Even though they're not of Privileged rank, they're granted certain immunities and rights. Have I made myself clear?" Everyone in the barracks mumbled assent. The Quaestor continued, "Now we come to the subject of deportment when meeting anyone of superior rank. As peons, you are obliged to greet a Free Citizen by his full title, in a respectful manner. With Privileged ranks such as Hadjis you speak only when spoken to, and then you stand with eyes downcast and hands clasped in front of you. You do not leave the presence of a Privileged Citizen until permission has been granted. You do not sit in his company under any circumstances. Understood? There is much more to be learned. My office of Quaestor, for example, comes under the classification of Free Citizen, but carries certain of the prerogatives of Privilege." The Quaestor glared at the men to make sure they understood. "This barracks is your temporary home. I have drawn up a chart to show which men sweep, which wash, and so forth. You may question me at anytime; but foolish or impertinent questions can be punished by mutilation or death. Just remember that you are the lowest of the low. If you bear that in mind, you might be able to stay alive." The Quaestor stood in silence for a few moments. Then he said, "Over the next few days, you'll all be given various assignments. Some of you will go to the germanium mines, some to the fishing fleet, some will be apprenticed to various trades. In the meantime, you're free to look around Tetrahyde." When the men looked blank, the Quaestor explained, "Tetrahyde is the name of the city you're in. It's the largest city on Omega." He thought for a moment. "In fact, it's the only city on Omega." "What does the name Tetrahyde mean?" Joe asked.
