of all Hirlaj?”

Horng’s eyes slowly closed and opened. TEBRON MARL WAS RULER LEADER IN THE REGION OF MINES. HE UNITED ALL OF HIRLAJ AND WAS PRIEST RULER.

“How did he unite the planet?”

TEBRON LIVED AT THE END OF THE BARBARIC AGE. HE CONQUERED THE PLANET BY VIOLENCE AND DROVE THE ANCIENT PRIEST CASTE FROM THE TEMPLE.

“But the reign of Tebron Marl is remembered as an era of peace.”

WHEN HE WAS PRIEST KING HE HELD THE PEACE. HE ENDED THE BARBARIC AGE.

Rynason suddenly sat forward, watching the stylus record these words. “Then it was Tebron who abolished war on Hirlaj?”

YES.

Rynason felt a thrill go through him. This was what they had all been searching for—the point in the history of Hirlaj when wars had ceased, when the Hirlaji had given themselves over to completely peaceful living. He knew already that the transition had been sharp and sudden. It was the last question mark in the sketchy history of Hirlaj which the survey team had compiled since its arrival—how had the Hirlaji managed so abruptly to establish and maintain an era of peace which had lasted unbroken to the present?

It was difficult even to think of these huge, slow-moving creatures as warriors … but warriors they had been, for thousands of their years, gradually building their culture and science until, apparently almost overnight, the wars had ceased. Since then the Hirlaji moved in their slow way through their world, growing more complacent with the passage of ancient generations, growing passive, and, eventually, decadent. Now there were only some two dozen of the race left alive.

They were telepathic, these leathery aliens, and behind those shadowed eyes they held the entire memories of their race. Experiences communicated telepathically through the centuries had formed a memory pool which each of the remaining Hirlaji shared. They could not, of course, integrate in their own minds all of that immense store of memories and understand it all clearly … but the memories were there.

It was at the same time a boon and a trial for Rynason and the rest of the survey team. They were trained archaeologists … as well schooled as possible on the worlds of this far-flung sector near the constantly outward-moving Edge, the limit of Terran expansion. Rynason could operate and if necessary repair the portable carbondaters of the team, he knew the fine points of excavation and restoration of artifacts and had studied so many types of alien anatomy that he could make at least an educated guess at the reconstruction of beings from fragmentary fossil-remains or incomplete skeletons … or exoskeletons.

But the situation on Hirlaj was one which had never before been encountered; here he was not dealing with a dead race’s remains, but directly with members of that race. It was not a matter of sifting fragmentary evidence of science, crafts and customs, finding out what he could and piecing together a composite picture from the remains at hand, as they had done with the artifacts of the Outsiders, those unknown beings who had left the ruins of their outposts and colonies in six galaxies already explored and settled by the Earthmen; all he had to do here was ask the right questions and he would get his answers.

Sitting there under that massive dome, with the quiet-eyed alien before him, Rynason couldn’t completely suppress a feeling of ridiculousness. The problem was that the Hirlaji could not be depended upon to be able to find a particular memory-series in their minds; the race memory was such a conglomeration that all they could do was strike randomly at memories until the correct area was touched, and then follow up from there. The result was usually irrelevant and unrelated information.

But he seemed to be getting somewhere now. Having spent three weeks with Horng, gradually learning a little about the ways of his alien mind, he had at last run across what might be the important turning-point in the history of Hirlaj.

Horng spoke, and Rynason turned to watch the stylus of the interpreter as it moved across the paper. TEBRON SPENT HIS YEARS BRINGING HIRLAJ TOGETHER. FIRST BY CONQUEST THEN BY … LEADERSHIP LAW. HE FORBADE … SCIENCES QUESTINGS EXPLORATIONS WHICH DREW HIRLAJ APART.

“What were these sciences?”

Horng closed and opened his eyes. MANY OF THEM ARE FORGOTTEN.

Rynason looked up at the alien, who sat quietly on a rough stone benchlike seat. “But your race doesn’t forget.”

THE MEMORIES ARE VERY FAR BACK AND ARE HARD TO FIND. THERE HAS BEEN NO EFFORT TO RETAIN CERTAIN MEMORIES.

“But you can remember these if you try?”

Horng’s head dipped to one side, a characteristic movement which Rynason had not yet managed to interpret. The shadowed, wrinkled eyes closed slowly. THE MEMORIES ARE THERE. THEY ARE THE SCIENCES OF KOR. MANY OF THEM ARE WARLIKE SCIENCES.

“You’ve mentioned Kor before. Who was he?”

KOR WAS IS GOD KNOWLEDGE.

Rynason frowned. The interpreter automatically translated terms which had no reliable parallel in Terran by giving two or three related words, and usually the concept was fairly clear. Not quite so with this sentence.

“God and knowledge are two different words in our language,” he said. “Can you explain your term more fully?”

Horng shifted heavily on his seat, his blunt fingers tapping each other. KOR WAS IS EXISTENCE WHICH WE WORSHIP OBEY ADMIRE FOLLOW. ALSO ESSENCE CONCEPT OF KNOWLEDGE SCIENCE QUESTING.

Rynason, watching the stylus, pursed his lips. “Mm,” he said softly, and shrugged his shoulders. Kor was apparently some sort of god, but the interpreter didn’t seem capable of translating the term precisely.

“What were the sciences of Kor?”

There was a silence as the stylus finished moving across the paper, and Rynason looked up at Horng. The alien’s eyes were closed and he had stopped the constant motion of his leathery grey fingers; he sat immobile, like a giant statue, almost a part of the complex of the hall and the crumbling domed building. Rynason waited.

The silence remained for a long time in the dry air of the empty hall. Rynason saw from the corner of his eye one of the dark little scavengers darting out of a gaping window. He could almost hear, it seemed, the noise of the brawling, makeshift town the Earthmen had established a little less than a mile away from the Hirlaji ruins, where already the nomads and adventurers and drifters had erected a cluster of prefab metal buildings and were settling in.

“What were the sciences of Kor?” Rynason asked again, not wanting to think of the cheapness and dirt of the Earth outpost which huddled so near to the Hirlaji domes.

He felt Horng’s quiet gaze, heavy with centuries, resting on him. THEY WERE ARE THOSE SCIENCES QUESTINGS WHICH KOR PROCLAIMED INFORMED WERE SACRED PART OF THE ESSENCE.

“Part of Kor?”

Horng’s head dipped to one side. APPROXIMATELY.

“How is this known? Tebron broke the power of the priesthood, didn’t he?”

TEBRON REPLACED THE PRIESTS. THE KNOWLEDGE WAS GIVEN TO TEBRON.

“Including the information that these sciences were prohibited?”

Horng shifted forward, like a massive block of stone wavering. His fingers moved briefly and then rested. THE MEMORIES ARE BURIED DEEPLY. TEBRON PROCLAIMED THIS PROHIBITION AFTER COMMUNICATING WITH KOR.

Rynason’s head jerked up from the interpreter. “Tebron spoke with Kor?”

After a pause, Horng’s dry voice came. APPROXIMATELY. THERE WAS … COMMUNICATION RAPPORT. TEBRON WAS KING PRIEST.

“Then Tebron made this prohibition in the name of Kor. When did this occur?”

THE KNOWLEDGE PROHIBITION WAS COMMUNICATED TO HIRLAJ WHEN TEBRON ASSUMED POWER RIGHT.

“The same day?”

THE DAY AFTER. TEBRON COMMUNICATED WITH KOR IMMEDIATELY AFTER OUSTING REPLACING THE PRIESTS.

Rynason watched Horng’s replies as they were recorded by the interpreter; he was frowning. So
