From the mouth of the cave, he could see his ship, perched on a level plain of scorched ground. He was in no rush to get back to it. In six days the inscription was done, cut deeply and eternally into the rock.
The thought that had been bothering him as he stared at the gray granite finally came to the surface. The only people who would come to read it would be visitors from the stars. How would they decipher it? He stared at the inscription angrily. He should have written it in symbols. But what kind of symbols? Mathematics? Of course, but what would that tell them about Man? And what made him think they would discover the cave anyway? There was no use for an inscription when Man's entire history was written over the face of the planet, scorched into the crust for anyone to see. He cursed his stupidity for wasting six days working at the useless inscription. He was about to uncreate it when he turned his head, hearing footsteps at the mouth of the cave.
He almost fell off the chair getting to his feet.
A girl was standing there. He blinked rapidly, and she was still there, a tall, dark-haired girl dressed in a torn, dirty one-piece coverall.
"Hi," she said, and walked into the cave. "I heard your hammer from the valley."
Automatically, he offered her his chair and created another for himself. She tested it gingerly before she sat down.
"I saw you do it," she said, "but I still don't believe it. Mirrors?"
"No," he muttered uncertainly. "I create. That is, I have the power to—wait a minute! How did you get here?" While he was demanding to know, he was considering and rejecting possibilities. Hidden in a cave? On a mountain top? No, there would be only one possible way....
"I was in your ship, pal." She leaned back in the chair and clasped her hands around one knee. "When you loaded up that cruiser, I figured you were going to beat it. I was getting tired of setting fuses eighteen hours a day, so I stowed away. Anybody else alive?"
