General Zarvas, the Army Commander who had placed himself at the head of the revolt, stood with his foot on the lowest step, his followers behind him. There was Prince Burvanny, the leader of the old nobility, and Ghorzesko Orhm, the merchant, and between them stood Tobbh, the chieftain of the mutinous slaves. There were clerks; laborers; poor but haughty nobles: and wealthy merchants who had long been forced to hide their riches from the dictator's tax-gatherers, and soldiers, and spacemen.

"You'd better let some of us go first sir," General Zarvas' orderly, a blood-stained bandage about his head, his uniform in rags, suggested. "You don't know what might be up there."

The General shook his head. "I'll go first." Zarvas Pol was not the man to send subordinates into danger ahead of himself. "To tell the truth, I'm afraid we won't find anything at all up there."

"You mean...?" Ghorzesko Orhm began.

"The 'time-machine'," Zarvas Pol replied. "If he's managed to get it finished, the Great Mind only knows where he may be, now. Or when."

He loosened the blaster in his holster and started up the long spiral. His followers spread out, below; sharp-shooters took position to cover his ascent. Prince Burvanny and Tobbh the Slave started to follow him. They hesitated as each motioned the other to precede him; then the nobleman followed the general, his blaster drawn, and the brawny slave behind him.

The door at the top was open, and Zarvas Pol stepped through but there was nothing in the great spherical room except a raised dais some fifty feet in diameter, its polished metal top strangely clean and empty. And a crumpled heap of burned cloth and charred flesh that had, not long ago, been a man. An old man with a white beard, and the seven-pointed star of the Learned Brothers on his breast, advanced to meet the armed intruders.

"So he is gone, Kradzy Zago?" Zarvas Pol said, holstering his weapon. "Gone in the 'time-machine', to hide in yesterday or tomorrow. And you let him go?"

The old one nodded. "He had a blaster, and I had none." He indicated the body on the floor. "Zoldy Jarv had no blaster, either, but he tried to stop Hradzka. See, he squandered his life as a fool squanders his money, getting nothing for it. And a man's life is not money, Zarvas Pol."

"I do not blame you, Kradzy Zago," General Zarvas said. "But now you must get to work, and build us another 'time-machine', so that we can hunt him down."
