The clouds that rimmed the sky now were headed to shed their load of moisture on the lowlands, affording them neither concern for the storm nor hope of water from it. All that it would bring them was a dark sky and a hard and dangerous walk without the stars. The sound of the aircraft intruded suddenly upon Niun's hearing: he shepherded human and dusei toward the deepest shadows, in the gathering darkMelein had sought shelter at once. If the aircraft saw anything it would be the image of a dus, a hot, massive silhouette for their instruments, something that was common enough to see in the wilds. If they fired at every dus on Kesrith, they would be a long time in their searching.
It passed. Niun, his fist entangled in the human's robes, a grip he had not relaxed since he herded them in together, let go and drew his first even breath.
"We may rest here a moment," said Melein in a thin, tired voice."It is a long walk from hereI must rest."
Niun looked at her, seeing her pain, that she had tried so long to hide. On the climb he had felt her every wince in his own vitals. And they were not to rest long. He was distressed with this, feeling that she was spending her last strength against this urgency to go farther. And without her, there was nothing.
He took the cloth for a blanket, and settled her against the side of the dus, into that friendly warmth, and was glad when she relaxed against that comfort he offered, and the line of pain knit into her brow, eased and began to vanish. "I will be all right," she said, touching his hand, And then her eyes widened and he whirled about upon a shadowa darting reach for a water flask and Duncan was gone, into the maze of rocks in the dark.
Niun swore and sprang after him, hearing the moaning roar of the dusei at once behind him. He came round the side of a pillar, half expecting ambush, which would have been idiocy on the human's part, and did not meet it. Nor was there sight or sign of Duncan. And he had left Melein, and sweat broke out on him, only to think what could happen if Duncan circled on them and attacked her, hurt as she was.
Then the sound of a dus hunting arose, moaning carried on the wind, and that cry meant quarry sighted. He blessed the several gods of his caste and ran toward that sound, pistol in hand.
So he met Melein, a pale wraith in the dark, and a dus beside her: and together they found the blind way where the other dusei had Duncan pent.
"Yai!" Niun called the beasts, before they should close in and kill; and they wheeled in a slope-shouldered and truculent withdrawal, only enough to let Duncan rise from the ledge where he had been cornered. He would not. He huddled there, unveiled in the scramble he had made, his naked face contorted with exhaustion and anger. He coughed rackingly, and his nose poured blood.
"Come down," said Melein.
But he would not, and Niun went in after him, pushing the dusei aside. Then Duncan made to move, but he fell again, and sat still and dropped his head on his folded arms.
Niun took the strap of the water flask and ripped it from Duncan's hand, and let him rest the moment, for they were all hard-breathing.
"It was a good attempt," said Niun."But the next time I will kill you; it is a wonder that the dusei did not kill you this time."
Duncan lifted his face, jaw set in anger. He shrugged, a gesture of defiance, a gesture spoiled by an attack of helpless coughing.
"You would have signalled the airship," said Melein,"and brought them down on us."
Duncan shrugged again, and came to his feet, went with them of his own accord in leaving the blind pocket The dusei were still blood-roused, and confused by being set on and drawn off their quarry; and Niun walked between them and the human. Melein followed after them as they went back to the place where they had abandoned their gear in the chase.
There they sank down where they had begun to rest, doubly exhausted now; and Niun stared at Duncan thoughtfully, thinking what might have happened, and what damage might have been done them.
There was Melein, fragile with her injury.
And there was an aircraft in the vicinity that wanted only the least error from them, the least slip into the open at the wrong moment, in order to locate and put an end to them.
"Cover your face," Niun said at last.
Duncan stared at him sullenly, as if he would defy that order, but in the end he lowered his eyes and arranged the veil, and stared at him still.
The dus moaned and reared up.
"Yai!" Niun ordered him, and he subsided, swaying nervously. The dus-anger stirred his own blood. He fought it down and mastered it, as a man must, who went among dusei, be more rational than they.
Duncan shifted aside, tearing his glance from them and the beasts, fixing it instead on the rock before them.
"We will move on," said Melein after a time, and pulled herself to her feet, carefully, painfully. She faltered, needed Niun's immediate hand to steady her.
But she set her hand then upon the dus, and the beast ambled out to the fore, and she was able to walk at its side, a slow pace and deliberatethe beast the only safety they had in this dark and close passage through the rocks.
Niun gathered up the water flasks, and left the human all the rest of the burden to carry, and hurried him on with a heavy hand, in among the two other dusei, before they should lose sight of Melein's pale figure.
The dusei, their oily hides immune to the poison of wind-flowers, their keen senses aware of other dangers, were the only means that they could dare to move after dark in this place; and the dark, as Melein was surely reckoning, was friendly to them as it would not be to those that pursued them.
The long walk led them into more open areas, where they crossed fearfully exposed stretches of sand under the ragged clouds; and they made it in among the sandstone formations again as they heard the distant sound of the aircraft still in the area.
It came close. Duncan looked to the skies as if in hope, looked back sharply as Niun whipped the av-tlen from its sheath, a whisper of edged metal.
They faced each other, he and Duncan, standing still as the aircraft circled off again, out of hearing. Niun put the weapon back into its sheath with a practiced reverse.
"Someone," Duncan said, his voice almost unrecognizable from his raw throat, "someone knows where to look for you. I somehow don't think my people would know that."
It was sense that struck cold to Niun's heart. He glanced at Melein.
"We cannot stop again for rest," she said. "They must not find us, not here. We must be at the place before light and come away again. Niun, let us hurry."
He pushed the human gently. "Come," he said.
"Is it her?" Duncan asked, nodded back toward Melein without moving from where he stood. "Is it somehow to do with her that the regul keep after you?"
"It could not be," he said with assurance; and then another thought began to grow in him with horrid clarity, mental process working again where for a long time there had been only shock. He looked again to Melein, spoke in the hal'ari, the high language. "It could not be that they are hunting us. They could not know that we exist. What are two mri to them, with others dead? Or how could regul have reached the edun to know survivors left it? They could not have climbed among those ruins. It is this human, this cursed human. He has ties back in the city, a master, and for his sake the regul tracked me across the flats. If it is the regul, they are still on that trail. There are regul and humans at work in this thing."
