The hope that his companions were nearby was shortlived. Lander entered the shelter of a dune and peered into the night. In the darkness ahead, there was no sign of Bhadla or Musalim. Turning his back to the blowing sand, he quickly checked his compass and saw that he was still on course.

Lander cursed his guides for leaving their charge behind, then urged his camel forward. As he passed out of the little shelter that the great dune had afforded, he tried to shield his face with his hand and forced himself to keep his eye open.

Blowing sand and darkness was all he saw.

At last Lander closed his eye and stopped to consider his options. At the most, he knew, his companions could only be a hundred yards away. In the dark and the storm, the distance might as well have been a hundred miles. Trying to track them would be as useless as trying to out-scream the blustering wind.

With his compass, he could easily continue toward the oasis, but that would not help him locate his companions. They might have lost their bearings and be riding in a completely different direction. In that case, his own movement would simply put more distance between them.

The best thing I can do, Lander realized, is wait as close as possible to the point where we separated. Perhaps Bhadla will be able to retrace his steps when he realizes that I've disappeared.

As the Harper turned his camel toward the shelter of the great dune behind him, he heard a camel's bellow to his right. Though the roar was faint and muted by the wind, Lander cringed. There was a note of urgency and terror to the bray that no storm could muffle.

He started forward in what he guessed to be the general direction of the sound. In the howling wind, one roar alone would hardly be enough to lead him to his companions, but it was all Lander had to follow. Besides, it occurred to him that his guides might be tormenting the beast so that its cries would lead him to them.

Lander rode a hundred steps forward and stopped. No bellows sounded. He turned his head to and fro, trying catch a glimpse of a silhouette or the hint of some sound other than the interminable wind. There was nothing.

Finally the Sembian glimpsed a bulky shadow stumbling toward him. He urged his mount forward when he saw that it was a limping camel. When he came closer still, Lander recognized the beast as Musalim's and went forward to grasp its reins. The saddle was empty, and the camel seemed dazed and weak.

Lander inspected the beast from his own camel. There were no wounds, but a dark blotch stained the saddle. He touched the stain and found it warm and sticky. Musalim's blood, he guessed. Lander dropped the dazed beast's reins and drew his sword.

When he turned back toward the place from which Musalim's camel had come, the Harper glimpsed a shadow rising out of the sand. It was about the size of a man, but the legs and arms seemed to stick from the body at peculiar angles, like a reptile's.

Lander needed to see no more to know that Musalim, and probably Bhadla too, had ridden into an ambush. The Sembian slapped the flat of his sword against his camel's shoulder, but the sluggish beast refused to charge. The shadow raised a crossbow and a pair of yellow, egg-shaped eyes flashed in the dark night.

The bolt took Lander below the right collarbone, nearly knocking him from his saddle. His arm went numb, and the sword dropped from his hand. Grasping the reins with his left hand, the Sembian jerked his camel around. The beast reacted slowly, resentful of Lander's harsh manipulations. Two more shadows rose out of the blowing sand.

"Turn, you stubborn scion of Malar!"

A bolt struck the camel's flank, and Lander felt the beast quiver. It decided to obey and sprang away with the proper sense of urgency.

The wounded Harper dropped the reins and slumped forward, sprawling face-down over the beast's hump. Agony assaulted him in crashing waves, but Lander hardly realized it. He was only dimly aware of his knees squeezing his mount's hump and the fingers of his good hand clutching its coat. Lander could not tell how long the camel continued to gallop. He knew only the agony in his chest, the warm wetness trickling down his arm, and the black waves assaulting his mind.

Eventually, the camel slowed to a trot. It could have been hours after the ambush or just minutes. Lander could not tell. He tried to sit upright and realized the effort would leave him unconscious. He settled for holding on.

At last the camel collapsed. It did not lie down or even stop moving. The beast just belched forth a plaintive moan, stumbled once on its buckling legs, then, in midstride, it pitched Lander face-first into the sand.

They lay together in a twisted heap, the camel wheezing in shallow gasps and Lander moaning in disjointed pain. The sand worked its way into their wounds and welled up against their windward sides, but neither the man nor the beast showed any sign of caring. Soon, the camel stopped panting, and Lander was alone in the storm.

By dawn the god of tempests, Kozah, had vented his wrath. The storm died, leaving a hot, dreary calm in its place. The heavy, wind-borne sand dropped back to the ground, but a pall of silt lingered high in the heavens, diffusing At'ar's morning radiance and setting the eastern horizon ablaze with crimson light. Ruha knew it would be many more days before the dust returned to the ground and Kozah's mark disappeared from the morning sky.

The widow went to the oasis pond and knelt at its edge, then rinsed the night's grit from her mouth. She and Kadumi had spent the night huddled under the remnants of her khreima, but the wind had worked its way under the heavy camel-hair tarp, covering her aba with sand and coating her nose and mouth with dust. More than once during the night, she had awakened with the feeling of being suffocated and found herself spitting out a mouthful of powdery silt.

Kadumi came and stood behind Ruha until she put her veil back in place, then kneeled beside her and splashed water over his grimy face. "Kozah must be angry with At'ar again," the boy said. "Maybe he saw the faithless harlot entering N'asr's tent. I have not seen such a storm in a year." He looked toward the camp.

The boy's camels were couched near where he and Ruha had slept, though so much sand had gathered against their windward sides that they looked more like a string of miniature dunes than a line of dromedaries. Beyond the half-buried beasts, the fallen tents of the Qahtani were covered by small knolls of sand. The only clue to what lay beneath the drifts were protruding bits of dyed cloth. Mounds of yellow sand buried even the stone-covered graves Ruha and Kadumi had dug for Ajaman and his father's family.

"I don't think Kozah is angry with At'ar," Ruha said, astounded by how tranquil the oasis looked compared to the gruesome scene she and Kadumi had found yesterday. "I think he is offended by the sight of the massacre."

Kadumi's mouth tightened, and he surveyed the oasis with narrowed eyes. "Then let us hope we can reach your father's tribe before this caravan of fork-tongued monsters," he said. "It would not be good if they made Kozah angry again."

The boy glanced at the sky for several moments, then looked back to Ruha and said, "With the dust from yesterday's storm still hanging in the sky, at least it will be a cool day. We'll trot our mounts. With luck, we won't lose them."

Ruha caught his arm, concerned. Pushing camels hard over long distances dehydrated them, which could be fatal for both animal and rider if they happened to collapse too far from water.

"Do you think it's wise to take such a risk?" she asked. "Even with favorable weather and extra mounts, we're a day and a half behind the caravan. If the drivers know where they're going and want to get there fast, we can ride all your camels to death only to find more corpses at Rahalat."
