Sun, stench, racket: market day at Helmand.

The sun was a G-0 star, not much different from Sol. Asked to generate a name for it, the computer called it Bilbeis. It blazed from the blue cloisonne dome of the sky. Beyond the Margush river and the canals that drew its waters for the croplands of Helmand and the other river valley towns, the land was a desert, baked brown and bare.

The stench went with city life. The twelve or fifteen thousand inhabitants of Helmand had no better notion of sanitation than throwing their rubbish, chamber pots and all, into the narrow, winding streets. After a few years, the floors of their dwellings would be thirty or forty centimeters below street level. Then it was time to knock down the whole house and build a new mud-brick structure on the rubble. Helmand perched on a hill of its own making, a good fifteen meters above the Margush.

As for the racket, expect nothing else when large numbers of people gather to trade, as the folk of Helmand did once a nineday. And they were people. Only by such details as hair and skin color, beard pattern, and shape of features could they be told at a glance from Terrans. There were more subtle internal differences, but David Ware and Julian Crouzet had no trouble passing as foreigners from a distant land.

The two Survey Service anthropologists strolled through the marketplace. They paused gratefully in the long shadow of a temple for the time it took to drink a cup of thin, sour wine.

In their boots, denim coveralls, and caps, they attracted some attention from the people swarming around them, but not much. The city dwellers were already typical urban sophisticates, though Helmand and the other towns of the Margush valley represented the first civilization on Bilbeis IV.

Most of the stares came from peasants, in from the fields with produce or livestock to trade for the things they could not make themselves. Here a farmer weighed out grain to pay for a new bronze sickle blade, there another quarreled with a potter over how much dried fruit he would have to give for a large storage jar. The latter man finally threw up his arms in disgust and stomped off to find a better deal.

David Ware had been taping the argument with a camera set in a heavy silver ring. "You think that one's unhappy," Crouzet murmured, "look at the trader over there."

The fellow at whom he nodded was from the Raidan foothills west of the Margush. He let his gray-green mustachios grow barbarously long and wore a knee-length tunic of gaudy green and saffron stripes. "You try to cheat me, you son of a pimp!" he shouted in nasally accented Helmandi, shaking his fist at the fat stonecutter who sat cross-legged in front of his stall.

"I do not," the stonecutter said calmly. "Seventy diktats of grain is all your obsidian is worth?more than you would get from some."

The hillman was frantic with frustration. "You lie! See here?I have three beastloads of prime stone. In my grandfather's day, my animals would have killed themselves hauling back to my village the grain that stone brought. Seventy diktats?faugh! I could carry that myself."

"In your grandfather's day, we would have used the obsidian for sickles and scythes at harvest time, and for edging war swords. Bronze was hard to come by then, and even dearer than stone. Now that we have plenty, we find it more useful. So what good is your obsidian? Oh, I can make some of it into trinkets, I suppose, but it is no precious stone like turquoise or emerald. The jewelry would be cheap and move slowly."

Ware turned away with a half-amused, half-cynical snort. "Even in a Bronze Age society, changing technology throws people out of work."

"That's true at any level of culture," Crouzet said. "I will admit, though, the pace has picked up in Helmand under Queen Sabium."

"I should say so." Ware's craggy face, normally rather dour, was lit now with enthusiasm. "She's one in a million."

His companion nodded. As if summoned by the mention of their ruler, a platoon of musicians marched into the square down the one real thoroughfare Helmand boasted: the road from the palace. They raised seashell trumpets to their lips and blew a discordant blast. The two Terrans winced. The market-day hubbub died away.

"Bow your heads!" a herald cried. "Forth comes Sabium, vicegerent of Illil the goddess of the moons and queen of Helmand." Actually, the word the herald used literally meant "lady king"; Helmandi had no exact equivalent for "queen," as Sabium was the only female ruler the town had ever known.

Fifteen years before, she had been principal wife of the last king. When he died, his firstborn son was a babe in arms, and Sabium administered affairs as regent. The town prospered as never before under her leadership. A few years later, the child-king died, too. Sabium ruled on, now in her own right, and did so well that no one thought to challenge her.

"I wonder what brings her out," Crouzet said, his eyes on the dirt. "She's missed the last couple of market days."

Ware nodded. "I didn't think she looked well, either, when she was here."

The royal bodyguard preceded the queen into the square. The troopers carried bronze-headed spears and maces with wicked spikes. They used their big leather shields to push people out of the way and clear a path to the raised brick platform in the center of the marketplace.

A retinue of Helmand's nobles followed. The hems of their long woolen robes dragged in the dust; their wide sleeves flapped languidly as they walked. Not for them the bright colors that delighted the semisavage obsidian seller: like the bodyguards and most Helmandis, they preferred white or sober shades of brown, gray, and blue. But gold and silver gleamed on their arms, around their necks, and in ear and nose rings.

A sedan chair borne by twelve husky servants brought up the rear of the procession. David Ware whistled softly when he saw it from the corner of his eye. "I'll bet she is sick, then!" he exclaimed. "She always walked here before."

"We'll know soon enough," Crouzet said calmly. He was a big moon-faced man; his phlegmatic nature made him a good foil for Ware, who sometimes went off half-cocked.

Skillfully keeping the sedan chair level, the porters carried it to the top of the platform, set it down, and scurried down the stairs. The white-robed priest of Illil who had accompanied them stayed behind. The shell-trumpets blared again. The priest drew back the silk curtain that screened the interior of the sedan chair from view.

"Behold the queen!" the herald shouted.

The crowd in the marketplace raised their heads. Ware lifted his arm as if to scratch, so he could record Sabium's emergence.

When he saw her, he tried to suppress his involuntary gasp of surprise and dismay but could not. It hardly mattered. The same sound came from Crouzet beside him and from the throats of everyone close enough to Sabium to see how ill she truly was.

A month before, Ware thought, she had been a handsome woman, even without making allowances for the differences between Terran and Helmandi standards of good looks. Her grayish-pink skin, light blue hair that receded at the temples, and downy cheeks seemed no more strange, after one was used to them, than Crouzet's blackness or his own knobby-kneed, gangly build. Even the false mustache she wore to appear more fully a king somehow lent her face dignity instead of making her ridiculous.
