To such an inheritance had humanity come, intruders lately at war with the mri and now at war with their world, almost scoured off its face by storms, harassed by the wild dusei, befriended only by the regul, who had killed off the mri for them, an act of genocide to please their human con­querors.

Duncan traversed the causeway at his own slow pace, savoring the acrid air. His bare face and hands were painfully assaulted by Arain's fierce radiation even in this compara­tively short walk. It was noon. Little stirred in the wild dur­ing the hours of Arain's zenith; but humans, safe within their filtered and air-conditioned environments, ignored the sun. Human authority imposed a human schedule on Kesrith's day, segmenting it into slightly lengthened seconds, minutes, hours, for the convenience of those who dwelled in the city, where daylight was visible and meaningful, but those were few. Universal Standard was still the yardstick for the scien­tific community of Flower, and for the warship that orbited overhead.

Duncan walked with eyes open to the land, saw the camouflaged body of a leathery jo, one of the flying creatures of Kesrith, poised to last out the heat in the shadow of a large rock saw also the trail of a sandsnake that had lately crossed the ground beside the causeway, seeking the nether side of some rock to protect itself from the sun and from predators. The jo waited, patiently, for its appointed prey. Such things Niun had taught Duncan to see.

Across the mineral flats, in the wreckage wrought by the fighting, a geyser plumed, a common sight. The world was re­pairing its damage, patiently setting about more aeons of building; but hereafter would come humans in greater and greater numbers, to search out a way to undo it and make Kesrith their own.

The mesh gave way to concrete at the city's edge, a border partially overcome by drifting sand. Duncan walked onto solid ground, past the observation deck of the Nom, where a surveillance system had been mounted to watch the causeway, and up to the rear door that had become main entry for hu­man personnel, leading as it did toward Flower and the air­field and shuttle landing.

The door hissed open and shut. Nom air came as a shock, scented as it was with its own filtered human-regul taint, hu­midified and sweeter than the air outside, that sunlight-over-cold heat that burned and chilled at once. Here were gardens, kept marginally watered during rationing, botanical speci­mens from regul worlds, and therefore important: a liver-spotted white vine that had shed its lavender blooms under stress; a sad-looking tree with sparse silver leaves; a hardy gray-green moss. And the regul-built halls high in the cen­ter, at least by regul standards gave a tall human a feeling of confinement. The corridors were rounded and recessed along one side, where gleaming rails afforded regul sleds a faster, hazard-free movement along the side without doors. As Duncan turned for the ramp, one whisked past almost too fast to distinguish, whipped round the corner and was gone. At that pace it would be a supply sled, carrying cargo but no personnel.

Regul tended much to automation. They moved slowly, ponderously, their short legs incapable of bearing their own weight for any distance. The regul who did move about afoot were younglings, sexless and still mobile, not yet having ac­quired their adult bulk. The elders, the muscles of their legs atrophied, hardly stirred at all, save in the prosthetic comfort of their sleds.

And, alien in the corridors of the Nom, humans moved, tall, stalking shapes strangely rapid among the squat, slow forms of regul.

Duncan's own quarters were on the second level, a private room. It was luxury in one sense: solitude was a comfort he had not had in a very long time, for he had come to Kesrith as attendant to the governor; but he was keenly aware what the small, single room represented, a fall from intimacy with the important powers of Kesrith, specifically with Stavros, the Honorable George Stavros, governor of the new territories of human conquest. Duncan had found himself quietly preempted from his post by a military medical aide, one Evans, E.; he had come back from Kesrith's backlands and from sickbay to find that state of affairs, and although he had hoped, he had received no invitation to move back into his old quarters in the anteroom of Stavros' apartments that post of regul protocol which, among their conquered hosts, humans yet observed meticulously in public. An elder of Stavros' high rank must have at least one youngling to attend his needs and fend off unwelcome visitors; and that duty now belonged to Evans. Duncan was kept at a distance; his con­tact with Stavros, once close, was suddenly formal: an occa­sional greeting as they passed in the hall, that was the limit of it. Even the debriefing after his mission had been handled by others and passed second-hand to Stavros, through the scien­tists, the medics and the military.

Duncan understood his disfavor now as permanent. It was Stavros' concession to the regul, who hated him and feared his influence. And what his position on Kesrith would be hereafter, he did not know.

It was, for his personal hopes, the end. He might have pro­moted himself to a colonial staff position by cultivating Stavros' favor. He was still due considerable pay for his five year enlistment in the hazardous stage of the Kesrithi mis­sion pay and transport to the world of his choice, or settle­ment on Kesrith itself, subject to the approval of the governor. He had been lured by such hopes once and briefly, half-believing them. He had taken the post because it was an offer, in an area and at a time when offers were scarce; and because he was nearing his statistical limit of survival on mis­sions of greater hazard. It had seemed then a way to survive, marginally at least, as he had always survived.

He had survived again, had come back from Stavros' serv­ice scarred and sunburned and mentally shaken after a trek through the Kesrithi backlands which the lately arrived regu­lars would never have survived. He had learned Kesrith as no human would after him; and he had been among mri, and had come back alive, which no human had done before him.

And in his distress he had told Stavros the truth of what he had learned, directly and trustingly.

That had been his great mistake.

He passed the door that belonged to Stavros and Evans, and opened his own apartment, Spartan in its appointments and lacking the small anteroom that was essential to status in the Nom, among regul. He touched the switch to close the door, and at the same panel opened the storm shields. The windows afforded a view of the way that he had come, of Flower on her knoll, a squat half-ovoid on stilts; of a sky that, at least today, was cloudless, a rusty pink. There had not been a storm in days. Nature, like the various inhabitants of Kesrith, seemed to have spent its violence: there was an exhausted hush over the world.

Duncan stripped and sponged off with chemical condi­tioner, a practice that the caustic dust of Kesrith made advis­able, that his physician still insisted upon, and changed into his lighter uniform. He was bound for the library, that build­ing across the square from the Nom, accessible by a base­ment hallway: it was part of the regul university complex, which humans now held.

He spent his afternoons and evenings there; and anyone who had known Sten Duncan back in humanity's home terri­tory would have found that incredible. He was not a scholar. He had been well-trained in his profession: he knew the mechanics of ships and of weapons, knew a bit of geology and ecology, and the working of computers all in areas necessary for efficiency in combat, in which he had been trained from a war-time youth, parentless, single-minded in the direction of his life. All his knowledge was practical, gathered at need, rammed into his head by instructors solely interested in his survival to kill the enemy.

That was before he had seen his war ended before he had seen his enemy murdered by regul; or shared a camp with the survivors; or seen the proud mri on human charity.

Two thousand years of records and charts and tapes lay in the regul library, truths concealed in regul language and regul obscurities. Duncan studied. He searched out what the mri had been on Kesrith, what they had been elsewhere, with an interest infinitely more personal than that of Flower's scien­tists.

Stavros disapproved. It flaunted attitudes and interests that regul feared and distrusted; and offending the regul ran counter to humanity's new policies. It embarrassed Stavros; it angered him, who had vast authority on Kesrith and in its new territories.

But the library still remained Duncan's choice on his hours of liberty, which were extensive in his useless existence. He had begun by making himself a nuisance among Flower's personnel, who themselves were mining the library for what could be gained, duplicating tapes and records wholesale for later study back in the labs of Elag/Haven and Zoroaster. Duncan searched out those particular records that had to do with mri, and made himself helpful to certain of the Flower personnel who could be persuaded to share his interest. With his own stumbling command of the regul tongue, he could do little himself toward solving the tapes or interpreting the charts; but he talked with the scientists who could. He rea­soned with them; he tried to make them understand, with all his insistence, that which he did not understand himself.

To learn what it was he had spent his life destroying, what he had seen utterly obliterated.

He gathered up his notes and his handmade dictionary and prepared to leave the room. The light on the panel flashed.

"Kose Sten Duncan," a regul voice said, still giving him his old title as Stavros' assistant, which surprised him. "Kose Sten Duncan.”

He pressed the button for reply, vaguely uneasy that any­one in the Nom chose to intervene with him, disturbing his obscurity. His earnest ambition now was simple: to be let alone, to take those assignments that might be given him through lower channels, and to be forgotten by the higher ones.

"I am here," he told the regul.

"The reverence bai Stavros sends you his order that you join him in his offices immediately.”

Duncan hesitated, heart clenched at the foreknowledge that his period of grace was over. Somewhere in the labyrinth of Flower papers must have been signed, declaring him fit for service; somewhere hi the Nom papers were being prepared that would similarly mark him down in someone's employ. Nothing on colonial Kesrith could remain without some des­ignated use.

'Tell the reverence," he said, "that I am coming now.”

The regul returned some curt syllable, ending the commu­nication; it lacked respect. Duncan flung his notes onto the table, opened the door and strode out into the corridor.
