The view had changed, and the strangeness of it made Rikud's pulses leap with excitement. All the stars were paler now than before, and where Rikud had seen the one bright central star, he now saw a globe of light, white with a tinge of blue in it, and so bright that it hurt his eyes to look.

Yes, hurt! Rikud looked and looked until his eyes teared and he had to turn away. Here was an unknown factor which the perfect world failed to control. But how could a star change into a blinking blue-white globe—if, indeed, that was the star Rikud had seen earlier? There was that word change again. Didn't it have something to do with age? Rikud couldn't remember, and he suddenly wished he could read Crifer's book on astronomy, which meant the same as stars. Except that it was variable, which was like change, being tied up somehow with age.

Presently Rikud became aware that his eyes were not tearing any longer, and he turned to look at the viewport. What he saw now was so new that he couldn't at first accept it. Instead, he blinked and rubbed his eyes, sure that the ball of blue-white fire somehow had damaged them. But the new view persisted.

Of stars there were few, and of the blackness, almost nothing. Gone, too, was the burning globe. Something loomed there in the port, so huge that it spread out over almost the entire surface. Something big and round, all grays and greens and browns, and something for which Rikud had no name.

A few moments more, and Rikud no longer could see the sphere. A section of it had expanded outward and assumed the rectangular shape of the viewport, and its size as well. It seemed neatly sheered down the middle, so that on one side Rikud saw an expanse of brown and green, and on the other, blue.

Startled, Rikud leaped back. The sullen roar in the rear of the world had ceased abruptly. Instead an ominous silence, broken at regular intervals by a sharp booming.

Change—

"Won't you eat, Rikud?" Chuls called from somewhere down below.

"Damn the man," Rikud thought. Then aloud: "Yes, I'll eat. Later."

"It's time...." Chuls' voice trailed off again, impotently.
