“Don’t make me laugh,” Andra said. “You’ve seen our men when they were in danger.”

The ship had lifted and was leaving Nobla behind. Watching the horizon ahead, Karn saw another city come into view within a short time. It looked exactly like Nobla. They must be a great people who could build cities like these, who could make ships that flew through the air.

But they could hardly be called men. What sort of man was it who did not have even the instinct for self preservation? What sort was it who would not defend his woman? Andra read Karn’s thoughts.

“What kind of men?” she said. “I’ll tell you. They never built the cities of Mahlo. Those have stood for thousands of generations, erected by some forgotten ancestors.

“The men of Mahlo have never had to fight. There was no danger here. So they spent their time in idle chatter, in philosophy, in the invention of luxuries. But they retained control of the government. When the Green Ones came out of the forests of the south and began their conquering march, our men decreed that we must retreat before them.

“When only Nobla and Luma remained to us, the men decreed that we must retreat from Mahlo to a world

without dangers. Unfortunately there is no such place.”

Karn thought for a moment. “What about the Green Ones?”

“They are more reptile than human, as you saw. But they do have a rudimentary intelligence. Added to their instinct for aggression it is sufficient to destroy us. Wait until you see our Council in session. You won’t wonder then.”
