"How long have you been in the valley, Jen? You and I are the same stock, speaking the same language. Earth stock. How does it happen, a colony of this size that no one ever heard of?"

"It's been nearly three hundred years since the Landing," she answered. "I have been told that for generations my people kept alive the hope that a ship would come from Earth and release them from the Korins. It never came. And, except by ship, there is no way in or out of the valley."

Trevor glanced at her sharply. "I found a way in, all right, and I'm beginning to wish I hadn't. And if there's no way out, where are we going?"

"I don't know myself," said Jen, and rose. "But my man came this way, and others before him."

She went on, and Trevor went with her. There was no place else to go.

The heat was unbearable, and they crept in the shadows of the rocks wherever they could. They suffered from thirst, but there was no water. The shoulder of purple basalt loomed impossibly tall before them, and seemed never to grow nearer.

For most of the day they toiled across the lava bed, and at last, when they had almost forgotten that they had ever dreamed of doing it, they rounded the shoulder and came staggering out of the badland into a narrow canyon that seemed like the scar of some cataclysmic wound in the mountain.

Rock walls, raw and riven, rose out of sight on either side, the twisted strata showing streaks of crimson and white and sullen ochre. A little stream crawled in a stony bed, and not much grew beside it.

Jen and Trevor fell by the stream. And while they were still sprawled on the moist gravel, lapping like dogs at the bitter water, men came quietly from among the rocks and stood above them, holding weapons made of stone.
