But despite himself, his mind wandered to the young women in the camp below. Were N'Garth and Valda really going to visit them? Perhaps they had already made their move. The idea created a cold hollow inside him. Why did he have to care so much about what was right and wrong that he was prepared to give up a bright fire and a pretty young girl laughing into his face? What was this absurd sense of duty that forced him to sacrifice bright eyes, moist lips, and teasing giggles for a night on a bare hillside?

At one point, he must have dozed. All he knew was that he woke with a jerk as his head toppled forward. He rubbed his eyes. It took him a moment to remember where he was. All four moons were in the sky. The last thing he remembered was Pran shining alone; it had to be very close to dawn. His next reaction was anger. Nobody had bothered to relieve him. He was about to climb back down to the camp when he noticed the tiny spark of light out on the dark plain. Was someone else out there, also camping for the night?

N'Garth and Valda were sleeping beside their own fire, and the women were some distance away. Either they had never gone to the girls or else they had, at some point, returned to their own blankets. He quickly roused them.

"There's a light out on the plain. It looks like another camp."

Valda grunted, coughed, and looked around blankly, but N'Garth was instantly awake, his hunter's instincts straight to the fore.

"Where?"

"It's some distance away."

N'Garth glanced at the embers of their own fire. "Can they see us?"

Harkaan shook his head. "I don't think so. We're far enough down in the hollow to be hidden from them." "Let's hope so."

"I think we should go and take a look."

N'Garth was already rolling up his blankets. Harkaan turned to Valda, who was slowly coming awake.

"You stay here and look after the women."

Valda stopped rubbing his eyes and scowled. He clearly wasn't pleased to be left out of the scouting party.

As Harkaan and N'Garth crept toward the light, they could see figures moving around a fire. For the last two hundred paces, they wormed their way through the grass on their bellies. The first gray-green of the predawn was streaking the horizon. When they thought they were close enough, they slowly raised their heads.

There were five people, four women and a single man, grouped around what had to be an early cookfire. Two of the women were eating, and the others looked as if they had just finished. Three other men were tending the needs of eight mounts, preparing them for travel.

"They must be making an early start."

Harkaan and N'Garth were too far away to be able to make out any tribal markings, but they could see that, like their own party, the strangers were wearing elaborate costumes and that their mounts' saddles and bridles were decked with streamers and flowers. Also like the Ashak-ai group, they appeared to be unarmed.

"They're going to the Valley."

"It looks that way."

The sky was becoming increasingly light, and Harkaan and N'Garth started to edge away. Again they crawled and then ran doubled over until they felt that they were safe from detection. Back at the camp, there was a single question.

"What do we do about them?"

The others seemed to be looking to Harkaan for some kind of direction. Still very conscious that he alone had spent the night on a bare hillside, he didn't answer immediately. Finally he allowed himself a half smile.

"First we eat, but we make no fire. We don't want to reveal ourselves until it's absolutely necessary."

"And then?"

"We wait until they're on the move. We let them get well ahead of us. If they turn back to confront us, we will have ample warning of any hostile intentions."

They gave the other party sufficient time to move well ahead before they saddled their own mounts and walked them out of the hollow. While they were readying the mounts, Harkaan found himself standing next to Con-chela. She looked at him questioningly.

"Why didn't you come to our blankets last night, Harkaan? Are you different from the others?"

Harkaan stiffened. "Someone had to stand watch."

"Is that the only reason?"

"It didn't seem right to break the Law when we're so close to the Gods." body had a word for it. It was a red ball, the height of a man across its diameter, and it hung in the air just above the heads of the riders. It glowed, not with the glow of fire but with a steady rhythmic pulse of color that was bright but had no warmth. The only thing Harkaan had ever seen that remotely resembled it was the glow of the stone when it showed the way.

The red sphere came closer, as if to inspect the winding procession of mounts and riders. Up ahead, terrified animals wailed. Necks arched and heads tossed while their fear released a rank, heavy smell. One mount reared, and then another. The red sphere just kept on coming, slow and relentless, riding the air. A mount in the party directly in front of the Ashak-ai bucked and screamed. Its rider tried to rein it in, but it lost its footing and toppled backward with its legs flailing. The mounts around it bucked and plunged. Harkaan had to fight down his own mount and, at the same time, his own fear. Was this a God? Somehow he didn't think so; maybe it was a messenger or a servant of the Gods. Except, if this was a messenger, what were the Gods like? He wanted to turn his mount and crash back down the path. He wanted to run, to flee. He wanted to keep on running until he was someplace where the Gods couldn't find or reach him. And yet he had no will. He couldn't do it. It was as if his arms and legs were no longer his own. He was truly and deeply scared, and there was nothing he could do about it.

The red ball abruptly lifted, rose into the sky, and vanished behind the nearest hill. Harkaan leaned forward and calmed his mount by patting its neck. Its scales were slick with greasy sweat. A strange silence seemed to have settled over the procession, and the only sound was the rattle of the animals' footfalls on the loose rocks. 1 he riders and even the mounts appeared to have passed

She hooked her foot into the stirrup and swung her leg over her mount's back. "You are different."

By noon, it was possible to see a dozen or more groups all riding slowly toward the hills. It seemed that every tribe on the plains, and even those from beyond, were sending their tribute to the Gods. The nearest party was now close enough for him to make out faces and even tribal markings. There were no threats, not even signs of recognition or salute. They simply rode parallel to each other, no party acknowledging that the others existed. That night, the fires on the plain were like stars in the sky. All six of the Ashak-ai stood and stared, overawed by the sheer size of this migration.

Halfway through the next day, there was no longer the slightest doubt that the end of the journey was in sight. Every group of riders was converging on the same narrow pass that wound up and through the first line of hills. There were now so many riders that there was a certain amount of congestion around the mouth of the pass. It was almost the time of single shadows when the Ashak-ai mounts were finally able to start picking their way up the narrow path. The path proved to be little more than a rock-strewn, dried-out watercourse that twisted andj turned between steep barren slopes and around folds in‹ the hillside. Dust and the smell of animal apprehension hung in the air. The mounts stepped gingerly on the un* even surface. Both humans and animals felt very close to something infinitely strange and infinitely powerful.

There was an alien sound in the air, a high-pitched hum somewhat reminiscent of the nightwhine of the air beetle. Then the noise grew louder and louder, and it was nothing like any sound Harkaan had ever heard. And then the thing appeared around a turn in the trail, and the noise, frightening as it was, became completely secondary. Harkaan had no word for it. He was sure that no- the point where they could continue to be afraid. Numbness had descended and gripped them. They had no alternative but to continue up the pass and into the unknown.
