Fall.

FOR ADMINISTRATIVE PURPOSES, the Earthmen during their years of occupation of Holman’s World had marked off boundaries arbitrarily here and here and here, choosing this parallel of latitude, that meridian of longitude, to encompass a district or sector. Since Belzagor itself knew nothing of parallels of latitude nor of other human measures and boundaries, those demarcations by now existed only in the archives of the Company and in the memories of the dwindling human population of the planet. But one boundary was far from arbitrary, and its power still held: the natural line dividing the tropics from the mist country. On one side of that line lay the tropical highlands, sunbathed, fertile, forming the upper limit of the central band of lush vegetation that stretched down to the torrid equatorial jungle. On the other side of that line, only a few kilometers away, the clouds of the north came rolling in, creating the white world of the mists. The transition was sharp and, for a newcomer, even terrifying. One could explain it prosaically enough in terms of Belzagor’s axial tilt and the effect that had on the melting of polar snows; one could speak learnedly of the huge icecaps in which so much moisture was locked, icecaps that extended so far into the temperate zones of the planet that the warmth of the tropics was able to nibble at them, liberating great masses of water-vapor that swirled upward, curved pole-ward, and returned to the icecaps as regenerating snow; one could talk of the clash of climates and of the resulting marginal zones that were neither hot nor cold, and forever shrouded in the dense clouds born of that clash. But even these explanations did not prepare one for the initial shock of crossing the divide. One had a few hints: stray tufts of fog that drifted across the boundary and blotted out broad patches of the tropical highlands until the midday sun burned them away. Yet the actual change, when it came, was so profound, so absolute, that it stunned the spirit. On other worlds one grew accustomed to an easy transition from climate to climate, or else to an unvarying global climate; one could not easily accept the swiftness of the descent from warmth and ease to chill and bleakness that came here.

Gundersen and his nildoror companions were still some kilometers short of that point of change when a party of sulidoror came out of the bush and stopped them. They were border guards, he knew. There was no formal guard system, nor any other kind of governmental or quasi-governmental organization; but sulidoror nevertheless patrolled the border and interrogated those who wished to cross it. Even in the time of the Company the jurisdiction of the sulidoror had been respected, after a fashion: it might have cost too much effort to override it, and so the few Earthmen bound for the mist-country stations obligingly halted and stated their destinations before going on.

Gundersen took no part in the discussion. The nildoror and the sulidoror drew to one side, leaving him alone to contemplate the lofty banks of white mist on the northern horizon. There seemed to be trouble. One tall, sleek young sulidor pointed several times at Gundersen and spoke at length; Srin’gahar replied in a few syllables, and the sulidor appeared to grow angry, striding back and forth and vehemently knocking bark from trees with swipes of his huge claws. Srin’gahar spoke again, and then some agreement was reached; the angry sulidor stalked off into the forest and Srin’gahar beckoned to Gundersen to remount. Guided by the two sulidoror who remained, they resumed the northward march.

“What was the argument about?” Gundersen asked.

“Nothing.”

“But he seemed very angry.”

“It did not matter,” said Srin’gahar.

“Was he trying to keep me from crossing the boundary?”

“He felt you should not go across,” Srin’gahar admitted.

“Why? I have a many-born’s permission.”

“This was a personal grudge, friend of my journey. The sulidor claimed that you had offended him in time past. He knew you from the old days.”

“That’s impossible,” Gundersen said. “I had hardly any contact at all with sulidoror back then. They never came out of the mist country and I scarcely ever went into it. I doubt that I spoke a dozen words to sulidoror in eight years on this world.”

“The sulidor was not wrong in remembering that he had had contact with you,” said Srin’gahar gently. “I must tell you that there are reliable witnesses to the event.”

“When? Where?”

“It was a long time ago,” Srin’gahar said. The nildor appeared content with that vague answer, for he offered no other details. After a few moments of silence he added, “The sulidor had good reason to be unhappy with you, I think. But we told him that you meant to atone for all of your past deeds, and in the end he yielded. The sulidoror often are a stubborn and vindictive race.”

“What did I do to him?” Gundersen demanded.

“We do not need to talk of such things,” replied Srin’gahar.

Since the nildor then retreated into impermeable silence, Gundersen had ample time to ponder the grammatical ambiguities of that last sentence. On the basis of its verbal content alone, it might have meant “It is useless to talk of such things,” or “It would be embarrassing to me to talk of such things,” or “It is improper to talk of such things,” or “It is tasteless to talk of such things.” Only with the aid of the supplementary gestures, the movements of the crest-spines, the trunk, the ears, could the precise meaning be fathomed, and Gundersen had neither the skill nor the right position for detecting those gestures. He was puzzled, for he had no recollection of ever having given offense to a sulidor, and could not comprehend how he might have done it even indirectly or unknowingly; but after a while he concluded that Srin’gahar was deliberately being cryptic, and might be speaking in parables too subtle or too alien for an Earthman’s mind to catch. In any case the sulidor had withdrawn his mysterious objections to Gundersen’s journey, and the mist country was only a short distance away. Already the foliage of the jungle trees was more sparse than it had been a kilometer or two back, and the trees themselves were smaller and more widely spaced. Pockets of heavy fog now were more frequent. In many places the sandy yellow soil was wholly exposed. Yet the air was warm and clear and the underbrush profuse, and the bright golden sun was reassuringly visible; this was still unmistakably a place of benign and even commonplace climate.

Abruptly Gundersen felt a cold wind out of the north, signaling change. The path wound down a slight incline, and when it rose on the far side he looked over a hummock into a broad field of complete desolation, a no-thing’s-land between the jungle and the mist country. No tree, no shrub, no moss grew here; there was only the yellow soil, covered with a sprinkling of pebbles. Beyond this sterile zone Gundersen was confronted by a white palisade fiercely glittering with reflected sunlight; seemingly it was a cliff of ice hundreds of meters high that barred the way as far as he could see. In the extreme distance, behind and above this white wall, soared the tip of a high-looming mountain, pale red in color, whose rugged spires and peaks and parapets stood forth sharply and strangely against an iron-gray sky. Everything appeared larger than life, massive, monstrous, excessive.

“Here you must walk by yourself,” said Srin’gahar. “I regret this, but it is the custom. I can carry you no farther.”

Gundersen clambered down. He was not unhappy about the change; he felt that he should go to rebirth under his own power, and he had grown abashed at sitting astride Srin’gahar for so many hundreds of kilometers. But unexpectedly he found himself panting after no more than fifty meters of walking beside the five nildoror. Their pace was slow and stately, but the air here, evidently, was thinner than he knew. He forced himself to hide his distress. He would go on. He felt light-headed, oddly buoyant, and he would master the pounding in his chest and the throbbing in his temples. The new chill in the air was invigorating in its austerity. They were halfway across the zone of emptiness, and Gundersen now could clearly tell that what had appeared to be a solid white barrier stretching across the world was in fact a dense wall of mist at ground level. Outlying strands of that mist kissed his face. At its clammy touch images of death stirred in his mind, skulls and tombs and coffins and veils, but they did not dismay him. He looked toward the rose-red mountain dominating the land far to the north, and as he did so the clouds that lay over the mist country parted, permitting the sun to strike the mountain’s highest peak, a snowy dome of great expanse, and it seemed to him then that the face of Kurtz, transfigured, serene, looked down at him out of that smooth rounded peak.
