Behind them the ramparts of the Great Wall had fallen below the horizon, lost among the rise of hills and supplanted by the spread of the sands; aside from a hint of mountains to the very distant north and south, the Takla Makan desert stretched around them, like a tongue sticking out from the Gobi in the east. It was a high, oblong, arid declivity of rock, sand, and a cluster of lakes that many of the region's nomadic people considered sacred. Usually it was scorching in what ought to have been savage high summer, but now the sun did little to relieve the lingering nighttime chill, though it was midmorning.

"We will be in An-Hsi tomorrow," Zangi-Ragozh said in Byzantine Greek as he squinted into the glare ahead of them; a stiff, cold wind was blowing, flinging a cutting spray of sand at them and their ponies and two horses. "We can rest for a day at least; let the animals recover a little before we continue on."

"We'd best find camels instead of horses while we're there," said Ro-shei from his place in the wagon. His Greek accent was slightly different from Zangi-Ragozh's, more Roman than his master's. "These ponies do very well, but I have no confidence in the horses' ability to hold up through this hard weather, and with food so scarce, we should look for easier keepers than our horses."

"Yes. They are flagging," said Zangi-Ragozh sadly. "The sand is bad for their hooves, and nothing I can treat them with has been sufficient to keep them wholly sound."

"You do not want to give them up, do you?" Ro-shei observed.

"No, I do not," said Zangi-Ragozh.

"Why?" Ro-shei indicated the gray Zangi-Ragozh rode. "You have had countless other horses over the years. Surely Flying Cloud is not so remarkable a horse that you do not want to part with him. Celestial horse or not, he is not so very remarkable, is he?"

"Yes, I have had many horses, and no, Flying Cloud is not the epitome of them all," said Zangi-Ragozh with a sad, wry smile. "But I know how the peoples of this region live, and I know they will not value a Celestial horse-particularly a gelding-very highly. Were Flying Cloud a stallion, he might be worth something as a sire. As it is, he is likely to go into the stew pot before very long. So will many others if there is much more cold."

"And that offends you," said Ro-shei.

"And saddens me," said Zangi-Ragozh.

"You cannot save any of them, even if you purchase every last one," said Ro-shei with an air of resignation that spoke of long experience.

"No, I cannot; that is what troubles me the most." Zangi-Ragozh shaded his eyes as he looked up toward the sun. "I should not be able to do this."

"Do you think it is the end of the world?" Ro-shei asked with little emotion.

"I have no idea, if you mean the whole of the world," said Zangi-Ragozh. He sighed. "Things are dwindling-warmth, sunlight, food-and there seems to be no end to it. I wondered at first if I had sufficient gold for the journey-I should have made more, I fear-now, I am beginning to wonder if I have enough food, for reprovisioning is going to be difficult, and perhaps impossible. The ponies eat little, but they do eat, and they must be fed or they will be worse than useless."

"If you had the chance, could you make more gold? Or jewels?"

"That is one reason I wanted to go to Kumul. The teaching center there ought to have an athanor, and for a price they should permit me to use it for a few days, which is all I require. If we had a handful of diamonds and a handful of emeralds, we should have enough to pay for anything we may need between here and Byzantium, and they would not weigh as much as gold, nor take up space we need. We can put them in the bottom of the grain-barrels, for safety." He pointed off to the east where a thin billow of dust shone in the hazy morning light, marking the progress of other travelers. "We are not wholly alone, after all."

"Which may or may not be a good thing," Ro-shei warned, eyeing the dust with suspicion. "There are bandits in this region."

"They are moving no faster than we are, and we are small pickings," Zangi-Ragozh said.

"The better to take as slaves."

"They will not take slaves, not now," said Zangi-Ragozh with remorseless conviction. "If you want slaves to have any worth, you must feed them, and no one can spare food."

They continued on, west by northwest, throughout the morning and into the early afternoon, finally coming to a stop by a thin stream that welled out of a cluster of rock and ran for a short distance before disappearing into the sand; it was fringed with low-growing green plants, none of which were flourishing.

"Do you think it is safe?" Ro-shei asked, remembering the streams they had crossed that had stunk of sulfur, and from which the ponies had refused to drink.

"It is a spring and should be wholesome," said Zangi-Ragozh, dismounting and leading Flying Cloud to the spring. He watched as the gray lowered his nose and took a long draft. "I think this is assurance enough."

Ro-shei got down from the box and led the four harness ponies toward the little spring, the wagon clattering along behind them, then went around to the rear of it to go get the two additional ponies and his horse from their tethers. "Shall I prepare nosebags?"

"Yes. And we'll let them rest a bit. I want us to keep going until we reach An-Hsi tonight, no matter how late. The ponies will be able to make the journey, and if the horses flag, they can be led." Zangi-Ragozh pointed to the distant expanse of dust. "They're no nearer, but no farther, so unless they are bound for An-Hsi as well, they are pacing us, and that troubles me."

"They could be making for An-Hsi, as you said."

"Yes, they could," Zangi-Ragozh agreed so genially that Ro-shei knew he was worried.

"What about them troubles you?" he asked.

Zangi-Ragozh shook his head. "I wish I could tell you. I have a sensation not unlike ants crawling on me, and that, rare as it is, often announces trouble."

In his nearly five hundred years with Zangi-Ragozh, Ro-shei had known Zangi-Ragozh to make such an admission less then a dozen times, and in all instances it had presaged difficulties. "I wonder if you would want to change our direction slightly. Perhaps, if they do the same, that would reveal their intention."

"Go west, then directly north?" Zangi-Ragozh suggested; he nodded to the wagon. "I will rest awhile and give you my decision when I rise."

"The sun does not seem to bother you as much as when we came here years ago," Ro-shei remarked as he watched Zangi-Ragozh climb into the wagon.

"You are right-it has weakened." He rubbed his face to get rid of the sand clinging to his skin. "That is the most worrisome of all." Before he let down the flap to close himself inside, he said, "Wake me if there is any change."

"You mean the other travelers?"

"I mean any change," said Zangi-Ragozh, and dropped the flap.

Ro-shei busied himself preparing nosebags for the ponies and horses, mixing grain, oil, bits of dried pears, and chopped hay for each animal, then fitted the nosebags over their bridles. Once the animals were eating, he undertook a little desultory grooming, brushing their coats free of the worst of the chafing sand. That done, he was about to climb back onto the driving-box for a moment's rest when he noticed a half-dozen large birds hidden in the verdure and decided to trap one for a meal. It took him a while to rig his snare and to bait it with a little pile of the horses' grain, but he was rewarded with a quick capture, and fresh, raw flesh for a meal. When he was finished, he buried the bones and feathers, then went to wake Zangi-Ragozh.

"Nothing untoward occurred?" Zangi-Ragozh asked as he came out of the back of the wagon.

"I managed to snare a bird to eat," said Ro-shei. "It was stringy and tough. The birds are not doing well."

"Better than dying and falling out of the sky, as so many have," said Zangi-Ragozh.

"The bird was still eaten," said Ro-shei.

"True enough," said Zangi-Ragozh, shrugging. "The travelers?"

"Still bearing west by northwest," said Ro-shei, pointing to the dust.

"Then we will change direction. It may delay us a bit, but we should still arrive at An-Hsi tonight." Zangi-Ragozh considered the sun. "We have a great deal of light left, but it is past its greatest strength-such as it is."

"An-Hsi by tonight," Ro-shei repeated as he led the spare ponies and his horse to the rear of the wagon to secure their leads. "You are determined on this."

"Yes. An-Hsi by tonight, and the road to Kumul in two days, three at the most, assuming we can buy camels for our horses," said Zangi-Ragozh as he tightened Flying Cloud's girth.

Ro-shei nodded. "Camels and ponies. We are joining all the other Silk Road merchants, if we acquire such animals."

"So much the better," said Zangi-Ragozh. "We will attract no notice, but for the smallness of our caravan."

"Would you want to travel with any others? Merchant trains, or others bound westward?" Ro-shei asked.

"Perhaps I might," said Zangi-Ragozh after a brief consideration. "It would depend upon the group and where they were bound."

"What about joining a caravan for part of the way?" Ro-shei recommended.

"That is a possibility," said Zangi-Ragozh. "I gather you believe that we would be safer in the company of others."

"It seems likely," said Ro-shei as he climbed back onto the driving-box and took the reins in his hands and gave the ponies the office to move, following Zangi-Ragozh westward, where the sun gleamed in the afternoon sky.

Less than a li later they found a jumble of nomad huts, most pulled over and torn apart, revealing the interiors of the structures, and the bodies of the inhabitants. A few carrion birds circled overhead, but not in the numbers that might have been expected a year ago. On the ground no herds of goats or ponies remained, only a few angry dogs that were circling a starving kid bleating for its mother. Zangi-Ragozh ran the dogs off and pulled in his horse, dismounting carefully, for Flying Cloud was sweating and tossing his head at the strong scent of blood and decay that hung over the place. "They wanted food; they killed everyone, even strong youngsters, and the women were not raped; they were hungry and in a hurry," he said as he made his way through the ruin of the camp. "The goats and ponies were for cooking."

"Anything else gone?" Ro-shei asked as he pulled the wagon in.

"I hardly know. I can find no barrels of grain or salt-meat, or butter, if they had any." He walked toward the largest hut, the only one that showed signs of burning. "They intended to do this, to raid quickly and slaughter anyone who stood against them. They singled this group out. They knew what they wanted and that they would find it here." He turned over a woven mat and found two beheaded children. "These people here were helpless, whoever they were."

"Do you know what group they belonged to? Is there a clan sign? I haven't seen one." Ro-shei stared about the destruction and pointed out a torn bit of cloth. "That flag is from the Land of Snows."

"So it is. And so is this embroidery, though these people were not, judging by their clothing and their faces. They must have traded with the people of the Land of Snows," Zangi-Ragozh said, holding up a cap of shearling wool. "They may have come from Chanchi-lah Pass."

"Not this year."

"No, probably not, which may mean they traveled between the Land of Snows and the Silk Road regularly or had contact with those who did. I am not familiar with all the clans between here and Kashgar, though someone must know them: we'll ask in An-Hsi," Zangi-Ragozh conceded as he continued to look for some sign of who had attacked. "I do not recognize this arrow," he said at last, lifting one from amid a tumble of kitchen pots. He went to give it to Ro-shei.

"Nor do I," said Ro-shei when he had examined it. "No, it's not familiar."

"Is there a new band of thieves or a warlord coming into the region? Or is this something else?" He took the arrow back, tapping it on his hand meditatively. "They say the Turks are becoming restive again."

"The arrow is not Turkish," said Ro-shei.

"I know; but if the Turks are moving, they will drive others ahead of them." He looked around again. "They are desperate, whoever they are."

"I surmise their numbers are small," said Ro-shei, "or they would have taken much more."

"I agree. They took what they could carry, and what they needed most." Zangi-Ragozh clenched his jaw. "The waste of it!"

"Do you want to feed on the kid?" Ro-shei asked. "If he is not to be wasted, as well?"

"I know it would be prudent to do so, and perhaps I can convince myself that such feeding is a kindness," Zangi-Ragozh answered in a tone of self-condemnation. "I can make myself believe-almost-that it would do no good to spare the creature to live another day; those dogs or some other wild animals will return to devour it when we leave."

"Then I will catch it; he's not far from us," said Ro-shei, securing the reins of the wagon and climbing down from the box. "His life will do some good."

"That is hardly consolation," said Zangi-Ragozh, approaching the center of the tumbled shelters, making a sweeping gesture at the devastation around them. "Most were felled where they stood. I doubt these people fought back, which may mean they were ill or starving or both. They certainly were not ready to defend themselves." He considered what he saw around him more critically. "We have not time enough to bury them, and I would not like to burn this wreckage." Slowly he paced away from Ro-shei, then came back again. "Well, have a last look, get the kid, and let us leave."

Accepting this decision, Ro-shei picked up a good-sized empty brass cauldron. "This is useful."

"So it is," Zangi-Ragozh agreed, glad to have something else to hold his attention in place of slaughtered people.

"Would you protest if I were to take it with us?" Ro-shei kept his question level.

"Do we have need of it?" Zangi-Ragozh asked in some surprise. "We have no reason to cook."

"Who knows?" Ro-shei replied. "It may be useful. Occasionally you need hot water, and in time we may want to trade it."

Zangi-Ragozh considered. "Is there room in the wagon for it?"

"I can make room," said Ro-shei confidently, grabbing the arched handle of the cauldron and hefting it onto his shoulder to bear it up into the wagon. "I'll get the kid shortly."

"He will not go far," said Zangi-Ragozh.

As if to confirm this, the kid bleated and came trotting from around the broken poles of one of the dwellings.

"It would seem he is willing," said Ro-shei, watching the baby goat approaching.

"It would seem he is lonely," said Zangi-Ragozh. "But you are right. There is no kindness in leaving him here to be eaten by dogs or desert cats."

"And he would be," said Ro-shei. "Tonight, tomorrow, but no later than that."

"Yes. He would," Zangi-Ragozh said, holding his hand out and clicking his tongue to encourage the kid, petting the small head as the animal came up to him.

"Have you got him?" Ro-shei asked over his shoulder.

"Yes. I'll be quick," said Zangi-Ragozh, and picked up the young animal, calming it with a gentle pat and an expert touch.

"It was a wise thing to do," Ro-shei said as they pulled out of the ruined encampment, headed northwest. He had stored a haunch of the kid in a cloth sack under the driving-box; the horses and ponies had been watered and were willing to keep up a good, steady trot. "You needed the blood, and I the flesh."

"I know," said Zangi-Ragozh distantly as he rode slightly ahead of the wagon. He shaded his eyes and looked eastward. "The travelers have not changed direction."

"Then the slaughter we found may have been what has been troubling you," Ro-shei said.

"Perhaps." Zangi-Ragozh was unconvinced. "At An-Hsi, we will get what news we can." He said nothing for a short awhile, then spoke in a calm voice. "We are going to find as bad, and worse, before this is over."

"Whatever this may be," said Ro-shei.

"Yes. Whatever it is that has taken place." Zangi-Ragozh forced enthusiasm into his next words. "At least we will find warmth and plenty again in the West."

"So you hope," said Ro-shei with unusual bleakness.

"Do you doubt it?" Zangi-Ragozh asked.

Ro-shei hitched up his shoulders. "I hope you may be right, my master, but-" He broke off, then went on, "In Holin-Gol, the men in the market called it the dark of the sun, and I am afraid that they had the right of it. The sun is in the sky, but it has no warmth, no strength, and the land suffers."

"Yes," said Zangi-Ragozh.

"You have lived much longer than I have, and you say you have not seen anything to equal this," Ro-shei continued.

"That is true," Zangi-Ragozh admitted.

"Then it may be that the world is ending," said Ro-shei.

"It may be," Zangi-Ragozh said quietly.

"You say nothing more than that?" Ro-shei challenged.

"What more can I say?" Zangi-Ragozh asked. "I hope we may find that this dark of the sun ends as we go west, but if it does not, then ..." He faltered, unable to continue. "The Egyptians called the West the abode of death."

"Can you starve to death? To the True Death?" Ro-shei asked bluntly. "Can I?"

"By all the forgotten gods, I hope so," said Zangi-Ragozh with quiet conviction.

This sobering remark silenced Ro-shei until after a brilliant sunset, when they turned northward; he pointed to the evening star. "It is bluer than I remember it."

"All the sky has changed colors," said Zangi-Ragozh. "Dawn and sunset and the midheaven at noon. Nothing is as it was."

"Do you think it is the same in the West?" Ro-shei asked uneasily.

"It is the same sky," said Zangi-Ragozh. "If this is some manner of invisible cloud, then it may dissipate-we must hope that it will-between this place and my native earth."

"Is that where we are going?" Ro-shei was startled.

"It lies between us and the farthest shores of Gaul, or Hispania," said Zangi-Ragozh. "It may serve our purposes to go there."

"To die?"

"If nothing else," said Zangi-Ragozh quietly. "There may be other advantages to going there if this cloud remains in the sky: I hope that the cloud is gone long before we reach those mountains, but if it is not gone, I will be glad that we have a place to go." Zangi-Ragozh peered into the deepening night. "The other travelers have made camp for the night. You can see their fires." He pointed eastward.

"So I can," said Ro-shei, and did not say anything more about their destination as they continued on toward An-Hsi.

It was nearing midnight by the time they saw the torches in the watchtowers of An-Hsi, and a short while later they could make out the fires of the travelers camped outside the brick walls of the town. The wind had come up, cold and cutting as knives, and the flames from the torches and campfires leaped and quivered under its invisible lash. As Zangi-Ragozh and Ro-shei drew nearer, they noticed that a mounted guard patrolled the limits of the camps, ready to fight off any attack that might come, so they made a point of making the kind of noise that meant little trouble as they approached, keeping to the center of the packed-earth roadway.

In a response to their arrival, a guard in a blue-dyed shuba and heavy, Hunnic leggings rode up on a feisty pony to halt them with his short lance. "Who are you? Where are you coming from? Where are you going? What is your business? What do you carry?" He spoke in Chinese and repeated himself in the strange dialect of An-Hsi, then in badly pronounced Persian.

"I am Zangi-Ragozh, a foreign merchant from Yang-Chau. I am bound for the Black Sea to trade in spices and dyes; at present I carry very little beyond dyes and feed for my ponies," he answered in Chinese as he got off his horse. "We have come from an encampment, half a day from here, which had been attacked and sacked by unknown men about a day before we got there."

"A sacked encampment, you say?" The guard was distrustful. "You will have to make a report to the Merchants' Council."

"I will. Others may be in danger from those who raided and killed," said Zangi-Ragozh.

"Small groups are always in such danger," said the guard with fatality. "Those who travel in the region know the risks they take. It is for them to prepare."

"And it is for you to warn them to be prepared," said Zangi-Ragozh levelly.

"So you may tell the Council," the guard told him.

"I certainly will. In the morning, if it is all the same to you, for I doubt the Council is sitting at this hour. just now, my traveling companion and I are in need of sleep." Zangi-Ragozh made a sign of respect to the guard. "Post one of your men to watch us tonight, if you think that necessary."

The guard frowned, scrutinizing the two newcomers. "I will post a watch on you."

"Good," said Zangi-Ragozh.

"How does it serve your purpose?" The guard was unused to such cooperation and found such acquiescence made him uneasy.

"So our movements may be accurately reported to the Council," said Zangi-Ragozh, tugging at Flying Cloud's reins to lead him to the wagon.

"Is there reason to do so?" the guard demanded. "Draw your wagon over there, to the base of the third watchtower. I will send two men to keep you secure for the night. In the morning, you will go to the Merchants' Council to make your report and to be assessed a duty for entering An-Hsi."

"I am most grateful," said Zangi-Ragozh.

The guard snorted in disbelief, but pulled his pony back so that Ro-shei could guide the wagon to the place he had indicated. "My men will be with you shortly," he said, and rode off at a good clip.

"Grateful?" Ro-shei echoed.

"Yes," said Zangi-Ragozh, leading his horse up behind the wagon. "I hope the Council is willing to trust what I tell them, and it is more likely they will if we're guarded and prove safe."

Ro-shei drew in the wagon and secured the reins. "What do you want from the Council?"

"I want as much of a safe passage as we may be given," said Zangi-Ragozh, going toward the front of the wagon.

"Do you think we will need safe passage?" Ro-shei asked as he got down from the driving-box.

"Oh, yes." Zangi-Ragozh secured Flying Cloud to the rear of the wagon and turned to loosen his girth. "So do you," he added cannily.

Text of a safe-conduct granted by the Merchants' Council of An-Hsi to the foreign merchant Zangi-Ragozh, along with an inventory of all duty paid on goods being carried and a record of all animals held and purchased by Zangi-Ragozh.

The Merchants' Council of An-Hsi presents this safe-conduct to the foreign merchant Zangi-Ragozh of Yang-Chau, ensuring him safe passage from An-Hsi to Kumul, also known as Ha-Mi, without the pain of additional duties imposed upon the goods he carries in a single wagon and on three camels, which were purchased in the market here for six silver bars and the exchange of two Celestial horses. Any escort sought by Zangi-Ragozh, upon acceptance of terms of employment, is to be provided and honored.

On the sixth day of the Fortnight of the Young Camels, at the Merchants' Council House in An-Hsi.
