"Gas, probably radon, solidified under the incredible pressures in the heart of Jupiter. Solar Surveys knows about them, for they were seen once, and even handled by men. There is an article about them in the Encyclopaedia of the Solar Planets. In 2036, they were discovered, mined by cybernetic machinery. Then on their way to Mars, the ship carrying the jewels was sabotaged and wrecked. Wreckage and frozen bodies were discovered on the rogue asteroid Hidalgo, but the jewels were missing." Pao Chung had shown growing interest in the conversation. He broke in to ask, "Stolen?" "Stolen, perhaps. Possibly they disintegrated at the time of the wreck, or they may have transmuted into something unrecognized by the searchers. They may have become tenuous enough to sink through the surface of Hidalgo and recrystallized inside. But the evil influence continues. We believe that they are still there, still in existence, working their hidden evil, warping the brains of men, producing social and political chaos. Five of my friends have lost their lives searching for this menace. Possibly the sixth is dead, too, since he vanished into the unknown and has not been heard from. "I tried, myself. Angel and I landed on Hidalgo and searched carefully. But Hidalgo is 'off limits' for spacemen. Solar Surveys sent the Space Patrol after us, and we fled before finishing our search. We were chased to Mars, traced and hunted to Venus. We crashed there, and while I tried to get money for new equipment, Angel got involved with Pao Chung. You know the rest. Now you see why I must go to Hidalgo." Khaljean shook his head in sorrow. "I understand. But you could never find your way through the maze." Ferris accused him with fanatical eyes. "You could help me to find my way." "Not I. I am too old, and I am not sure that I approve of your meddling. Not that I would try to stop you, but don't count on help from me. How do you know that this alien machine is what you say? Its purpose may be good, not evil. Some higher intelligence may have placed it in our system as a governor to influence mankind, to shield man from his own follies. It may be a warning road sign to keep us from crashing into a dead end. Our utopias sound very dull to me, they may easily be a dead end for mankind. I like the interesting and amusing variations of chaos, so let me cling to them. Follow your destiny, if you will. I won't stop you." Ferris looked pitifully young, but he stood his ground with absurd pride and courage. "Right or wrong, I must try," he said evenly. "And I won't grant the right of alien interference. Man, too, has a right to work out his destiny, good or bad." Angel spoke up eagerly for his partner. "I won't say I know what you're talking about, and maybe I'm too stupid and ignorant to understand. But as a victim of 'chaos' I don't appreciate it."
