There had been a madness, and the river crossing had become a place of horror and death. The teroes had sensed the blood of men and mounts, and they were circling in the hot iron-gray sky, gliding on leathery wings and uttering hoarse, raucous cries. The bolder ones had already started to land, flapping and stretching, their long beaked heads turning this way and that, always poised for instant flight but, at the same time, always moving toward the fallen prey with their scrabbling sideways gait. A mount thrashed and contorted in its final agony, snapping at the hideous gaping wound in its stomach. The huge Brana-ma hunting dogs had caused this particular animal's downfall. The flying reptiles retreated to a safe distance and crouched, waiting for its dying struggles to end. The mount clawed at the loose sand, trying to rise, but the effort was too much for it. It shuddered and died. The teroes started to close in again.

For a while, the waters of the scant, high summer river had run red, but now, once again, they sparkled clear. The awful stain of mortal combat had been borne downstream, and it had already become history. Har-kaan splashed through the shallows, staring with dull horrified eyes at the wreckage that was left by the fighting. There was blood running down the side of his face from where a spinning platee had sliced his forehead. An angry, throbbing pain still pulsed through his shoulder and extended all the way up to the nerve clusters in the back of his neck. The Brana-ma warrior, the one with the black and yellow diamond-patterned snake painted on his left cheek, had been looking to finish him with a single blow from his war club. It had been intended to crush his skull, but at the last minute, Harkaan had desperately pivoted from the hip and the club had smashed down on his shoulder. In shock from the pain and driven by the strange new instincts of madness, he had gutted the man with his glassknife. The warrior's blood still stained his breechclout, his leggings, and his beaded chest piece.

Some of the bodies sprawled as though sleeping. Others were twisted into grotesque and unnatural parodies of what they'd been when alive. Harkaan avoided looking at the expressions on their faces. A mount lay half in and half out of the water. Its neck was stretched out, and its powerful back legs angled into the air. Spears stuck up like sinister leafless reeds, their points buried in the river mud or the dry, bare ground. The harsh hot Lawka-a wind that made men so quick to anger was still blowing, making streamers of the ribbons that decorated the weapons.

It was hard to remember how or why the conflict had started. When the twenty young men of the Ashak-ai had left the village, they had been nothing more than a simple hunting party, wearing the bands of ocher paint that designated them as such. Even then, though, there had been an awareness that something was wrong. The dry season had gone on far too long. Wells had run dry, and streams had dwindled until they were little more than trails of drying mud. The hot winds blew relentlessly. The nights brought no relief. A terrible lethargy had set in, punctuated only by bursts of sudden, out-of-control anger. Game had become so scarce on the high plains that a hunting party could go out for days and return with nothing more than a single sobore. The reserves of meal and dried meat were dangerously depleted, and even water had to be rationed. The old people of the village had become so sere and brittle that they seemed in danger of blowing away. The children were wide-eyed with hunger, and very soon the bellies of the youngest would start to swell and and starvation death would be among them. The omens and portents offered no hope or consolation. Brood mounts dropped their eggs long before the appointed time, and two human babies were stillborn. The elders and the shaman spent long hours in the Lodge of the Spirits, offering prayers to the ancestors and even making supplication to Ka-La-Lan, the Mother of the Hunt, a deity who was never trivially bothered. No help came. If anything, the heat grew worse and the Lawka-a blew as hard as ever.

For the first four days out, the hunting party found nothing; it was as if all life had fled from the plains. The grass itself was dying. As the hunters ranged farther and farther afield, they were increasingly aware that they were starting to infringe the treaties by moving into the traditional hunting grounds of other peoples. It was a serious offense, but they had little choice. They could not return to the village empty-handed.

When they saw the cloud of dust for the first time, a great surge of hope welled up in the heart of each of them. The meetha herds had returned. The cloud was relatively small, and there was no way that any of them could pretend that it was one of the huge armies of the waddling, duck-billed fehlapods whose vast migrations took them across the high plains soon after the start of the rainy season, but it might be an isolated group, thrown off track by the unnaturally long drought. What- ever it was, it was certainly better than nothing. They could return to the village with both honor and the des perately needed fresh meat. It took another half day for the disappointment to fall on them. At first they resisted the unpleasant truth. It had to be a meetha herd. Finally they could deceive themselves no longer. The dust cloud was moving too quickly and with too much purpose. It couldn't be meetha causing it. If anything, it was a hunting party similar to themselves, most likely from the Brana-ma, also pushing to the limits of their accepted territory. Despite the gut-wrenching realization that there was still no game and probably none in the direction from which the other party was coming, a certain excitement spread through the Ashak-ai hunters. If they kept on going, there would undoubtedly be a confrontation with the young men of the other tribe.

This kind of confrontation wasn't uncommon, and it was conducted according to a time-honored protocol. The formal insults were exchanged, and then the warriors would engage in the largely simulated ritual violence of toucou, in which combatants would attempt to strike each other lightly with the blunt end of their stabbing spears. The worst that could happen was that a few tempers would be lost, heads might be cracked, or an arm or a leg might be broken.

The two parties had met at the Great Maru River* which had dwindled to a number of shallow rivulets that meandered between banks of damp sand. The riders of the Ashak-ai had halted at the top of a line of low bluffs that followed the outswing of the river's curve. Below them, across the riverbed, the Brana-ma also stopped. As the two hunting parties cautiously approached each other, a certain unease spread through the Ashak-ai. The Brana-ma-by then it was easy to recognize the tribal markings on their mounts-had a pack of large, semi-wild hunting dogs with them. And the Brana-ma them- selves wore the swirling black and yellow devil paint of a raiding party.

At first, the meeting had followed normal protocol, The insults were exchanged. Ga-Niru, the eldest of the Ashak-a hunters and the leader of the party, stood up in his stirrupss and yelled across the river. The young men of the Brana-ma must copulate with t.heir mothers and sisters! No normal woman would lie with them!"

The Brana-ma leader was a disturbing sight. His whole body was painted a uniform yellow-the paint of one who is no longer sane. But his reply was comfortingly normal.

And the young men of the Ashak-ai copulate with their dogs because their mothers and sisters are too filthy and hideous for even them to lie with."

Taunt and countertaunt had escalated until the leader of each party let out a bloodcurdling scream. They charged at each other.
