"My assistant noticed that we had an even number of worshipers. We require an odd number, preferably ending in three. Where the sacred and the profane laws are in conflict, the profane must yield. So we let you in despite the government ruling."
"It's a ridiculous ruling," Barrent said.
"Not really. Like most of the laws of Omega, it is designed to keep the population down. Omega is an extremely barren planet, you know. The constant arrival of new prisoners keeps swelling the population, to the enormous disadvantage of the older inhabitants. Ways and means must be sought to dispose of the excess newcomers."
"It isn't fair," Barrent said.
"You'll change your mind when you become an older inhabitant," Ingemar said. "And by your tenacity, I'm sure you'll become one."
"Maybe," Barrent said. "But what happened? The temperature must have dropped nearly a hundred degrees in fifteen minutes."
"A hundred and eight degrees to be exact," Uncle Ingemar said. "It's really very simple. Omega is a planet which revolves eccentrically around a double star system. Further instability, I'm told, comes from the planet's peculiar physical make-up—the placement of mountains and seas. The result is a uniformly and dramatically bad climate characterized by sudden violent temperature changes."
The assistant, a small, self-important fellow, said, "It has been calculated that Omega is at the outer limits of the planets which can support human life without gross artificial aids. If the fluctuations between hot and cold were any more violent, all human life here would be wiped out."
"It's the perfect punitive world," Uncle Ingemar said proudly. "Experienced residents sense when a temperature change is about to take place and get indoors."
"It's—hellish," Barrent said, at a loss for words.
