Fors stayed just long enough to be sure that they were indeed coming, that whatever taboo had help them back no longer operated. Then he fled, skimming lightly at his sure woods’ pace, back to where he had left Lura and Arskane. The Beast Things did not seem too cheerful about their venture and their starting pace was slow. They walked as if they expected to find traps under their feet. There was hope that the pursued could keep ahead of them.

The mountaineer found Arskane impatient, Lura crouched on an outcrop, her eyes glowing in the dark. Fors grabbed up the equipment he had discarded as he gasped out his news.

“I have been thinking,” Arskane’s slower but deeper voice cut through his report. “We do not understand the weapons of the Old Ones, those which could make a desert such as this. Was there only one bomb which fell here, or were there more? But the heart of such a place would be more dangerous than its lip. If we head straight across we may be going to that death tradition promises for those who invade the ’blue places. But if we circle we may—”

“There is the matter of time. I tell you trackers run on our heels now.”

“Yes, and they track by scent. There is at hand an answer to that.”

Arskane’s moccasins plowed through a pool, sending up spray. Fors understood. The threat of stream might be their salvation after all. But, since the rain had ceased, the water was shrinking rapidly in volume, almost as if the rocky soil over which it ran was a sponge to suck it up.

Fors started ahead, his night sight picking out the pit-fals and bad footing for both of them. Sometimes it was only his hand which kept Arskane on his feet. The big man stumbled stubbornly on, his breath torn out of him in harsh gasps. Fors knew from the grip of cramp in his own leg muscles what tormented the other. But they must gain ground—gain it while the pursuers, still suspicious of the Blow-Up Land, traveled slowly.

Then, long after, Arskane fell and, although Fors allowed them both a rest, he could not get to his feet again. His head slumped forward on his chest and Fors saw that he was either unconscious or asleep, his mouth twisted with pain. But what was worse were the seeping stains on the bandage which still bound the wounded shoulder.

Fors pressed the palms of his hands against his burning eyes. He tried to think back—was it only last night they had slept in the city tower? It seemed a week behind them. They could not keep on at this rate, that was certain. Now that he relaxed against a sandy bank he was afraid he could not make the effort to get up again. He must keep. And there was the matter of food also. How large was this Blow-Up desert? What if they must go on and on across it—maybe for days?

But they would be dead before days passed. Would it be better to choose a likely place now and make a last stand against the Beast Things? He dug his eyes again. He dared not sleep now. Then he remembered Lura.
