Cameron's sense of caution returned as he remembered the previous results of indiscreet announcement of his purpose. He wiped the stream of sweat from his face and neck and took a good look at the Id. * * * * * The Idealists were of an anthropomorphic race, dark-skinned like the terran Indian. Very few of them had ever appeared on Earth, however, and this was actually Cameron's first view of one in the flesh. He knew something of their reputation and characteristics from very brief study at the Institute--but no one really knew very much of the Ids as far as Earthmen were concerned. The warning of Fothergill to keep to the main line of his research sank to the bottom of his mind as he leaned toward the stranger with a fresh sense of excitement inside him. "I have never felt you could understand another man unless you spoke his language," he said in his not too stumbling Markovian. The Id, like himself, was dressed in the briefest of garments and perspiration poured from the dark skin as he nodded. "You speak sounder wisdom than one usually meets in a stranger," he said. "May I introduce myself: Sal Karone, servant of the Master Dalls Ret Marthasa?" Cameron introduced himself and cautiously explained that he and Joyce were on their honeymoon, but had a side interest in the history and customs of the Markovian Nucleus. "My people know so little about you," he said, "it would be a great privilege to be able to take back information that would increase our mutual understanding." "All that the Idealists have belongs to every man and every race," said Sal Karone solemnly. "What we can give you may be had for the asking. But I would give you a word of warning about my Masters." Cameron felt the flesh of his back tingle with sudden chill as the eyes of the Id turned full upon him. "Do not try to find out the hidden things of the Masters. That is what you have come for, is it not, Cameron Wilder? That is why you have taken so much trouble to learn the language which we speak. I say do not inquire of the things about which they do not wish to speak. My Masters are a people who cannot yet be understood by the men of other worlds. In time there will be understanding, but that time is not yet. You will only bring disaster and disappointment upon us and yourselves by attempting to hasten that time." "I assure you I have no intention of prying," said Cameron haltingly. He fumbled for the right Markovian words. "You have misunderstood--We come only in friendship and with no intention of disturbing--" The Id nodded sagely. "So many crises are originated by good intentions. But I am sure that now you understand the feelings of my Masters in these things that you will be concerned only with your own enjoyment while in the Nucleus. And do come to the centers of the Idealists, for there is much we can show you, and our willingness has no limits."
