Land and Overland Omnibus

CHAPTER 7



Toller knew it was only his imagination, but an abnormal quietness seemed to have descended over the Five Palaces area of Ro-Atabri. It was not the sort of quietness which comes when human activity is in abeyance—it was more as if an invisible blanket of soundproof material had been pressed down over everything in his vicinity. When he looked about him he could see evidence that carpenters and stonemasons were busy with their restoration work; bluehorns and wagons were sending up clouds of dust which added scumbles of yellow to the blue of the foreday sky; ground crew and airmen were going about their business of getting the ships ready for the round-the-world flight. Everywhere he looked there was purposeful movement, but the noises of it seemed to be reaching him through the filters of distance, attenuated, lacking in relevance.

The flight was due to begin within the hour, and it was that fact—Toller knew—which was numbing his reactions, separating him from the perceived world of the senses. Nine days had passed since Vantara's departure for Overland, and during that time he had sunk into a mood of depression and apathy which had defied all efforts to overcome it.

When he should have been preparing his men and his ship for the circumnavigation he had been lost in thought, living and reliving that strange hour with Vantara at the Migration Day festivity. What had prompted her to behave as she had? Knowing that she was on the eve of quitting the planet altogether, she had raised him to the heights—he could still feel her lips against his, her breasts cupped in his hands—only to dash him down again with her sudden callous aloofness. Had she been playing cat-and-mouse on a whim, passing a dull hour with a trivial game?

There were moments in which Toller believed that to be the case, and at those times he plumbed new depths of misery, hating the countess with a passion which could whiten his knuckles and rob him of speech in mid-sentence. At other times he saw clearly that she had exerted herself to break down barriers between them, that she considered him a person of value, and that she would indeed be waiting to receive him when next he set foot on Overland. In those periods of optimism Toller felt even worse, because he and his love—the finest and most desirable woman who had ever lived—were literally worlds apart, and he was unable to imagine how he could endure the coming years without seeing her.

He would stare up at the great disk of Overland, its convex vastness crossed again and again by streamers of cloud, and wish for some means of instantaneous communication between the sister planets. There had been fanciful talk of some day building huge sunwriters, with tilting mirrors as large as rooftops, which would have been capable of sending messages between Land and Overland. If such a device had existed Toller would have used it, not so much to talk to Vantara—bridging the interworld gulf in that unsatisfactory way might have made his yearnings even more insupportable—but to get in touch with his father.

Cassyll Maraquine had the power and influence to obtain his son a special release from the Land mission. In the past, before he had been touched by the madness of love, Toller had scorned such uses of privilege, but in his present state of mind he would have seized on the favour with unashamed greed. And now, to make matters worse, he was on the point of setting out on a voyage which would take him through the Land of the Long Days, that distant side of the planet where he would not even have the spare consolation of being able to see Overland and in his mind's eye watch over Vantara while she went about her oh-so-special life…

"This will never do, young Maraquine," said Commissioner Kettoran, who had approached Toller unnoticed, making his way among piles of lumber and other supplies. He was wearing the grey robe of his office, but without the official emblems of brakka and enamel. Another man of his rank might have sequestered himself in imposing quarters or only ventured abroad with an entourage, but Kettoran liked to wander unobtrusively and alone through the various sections of the base.

"Instead of mooning around here like a maiden with the colic," he continued, "you should be checking the loading and balance of your ship."

"Lieutenant Correvalte is dealing with all that," Toller replied indifferently. "And probably making a better fist of it than I would."

Kettoran pulled the brim of his hat down over his eyes, creating a prism of shade from which he regarded Toller with concern. "Listen, my boy, I know it is none of my business, but this infatuation with the Countess Vantara bodes ill for your career."

"Thank you for the advice." Toller deeply resented the elderly man's words, but he had too much respect for Kettoran to hint at his anger other than by mild sarcasm. "I'll keep your good counsel in mind."

Kettoran gave him a small, sad smile. "Believe me, son, before you know it, these days which seem so interminable and so full of pain will be nothing more than faint memories. Not only that—they will seem joyous in comparison to what is to come. You are foolish not to make the most of them."

Something in Kettoran's voice affected Toller, drawing his thoughts away from his own circumstances. "This hardly seems credible," he said, claiming the right to intimacy he had earned on the interplanetary crossing. "I never expected to hear Trye Kettoran talk like an old man."

"And I never expected to be an old man—that was a fate exclusively reserved for others. Ponder on what I am telling you, son. And don't be a fool." Commissioner Kettoran squeezed Toller's shoulder with a thin hand, then turned and walked away towards the eastern flank of the Great Palace. His gait seemed to lack something of its usual jauntiness.

Toller stared after the commissioner for a moment, frowning. "Sir," he called out, prompted by a sudden unease, "is all well with you?"

Appearing not to hear, Kettoran continued on his way and was soon lost to view. Toller, now troubled by premonitions about the commissioner's well-being, somehow felt obliged to pay more heed to the advice he had just been given. He began making conscientious efforts to follow what was undoubtedly good philosophical counsel—after all, he was young and healthy and all his life lay before him—but each time he ordered himself to feel cheerful the only result was an obstinate upsurge of his misery. Something within him was antagonistic to reason.

He returned to his ship and went on board, supervising the departure arrangements with a gloomy inattentiveness which he knew was bound to communicate itself to the crew. Lieutenant Correvalte responded by becoming even more wooden and correct in his manner. The voyage was expected to take about sixty days, assuming no mishaps were to occur, and the gondola was a very small space for eight men to be cooped in for that length of time. The psychological strain would be considerable even under ideal conditions, and with a commander who was making it clear from the outset that he had no stomach for the mission there could be problems with morale and discipline.

Eventually all the formalities were completed, and the signal for departure came when a trumpet sounded on board the lead ship. The four vessels took off in unison, their jets sending flat billows of sound rolling out across the parks which surrounded the Five Palaces and into the sunlit environs of Ro-Atabri. Toller stood at the rail, hand on the hilt of his sword, leaving the control of the ship to Correvalte, and stared out at the sprawling expanse of the old city. The sun was high in the sky, nearing Overland, and the gondola was completely contained within the shadow of its elliptical gasbag, making the scenery beyond look exceptionally bright and sharply defined. Traditional Kolcorronian architectural styles made extensive use of orange and yellow bricks laid in complex diamond patterns, with dressings of red sandstone at corners and edges, and from a low altitude the city was a glittering mosaic which shimmered confusingly on the eye. Trees at different stages of their lives provided islands of extra colour which ranged from pale green to copper and brown.

The ships made a partial circuit of the base and took a north-eastern course, seeking the trade winds which would help conserve power crystals during the voyage. Local surveys had indicated that there would be no shortage of mature brakka trees along the route, but broaching their combustion chambers to obtain the green and purple crystals would have been a time-consuming business, and it was intended that the little fleet should complete the circumnavigation using only its on-board supplies.

Toller gave an involuntary sigh as Ro-Atabri began to slide into the distance aft of his ship, its various features flattening into horizontal bands. The voyage, with all its promised tedium and privation, had begun in earnest, and it was time for him to face up to that fact. He became aware of Baten Steenameert, newly promoted to the rank of air-sergeant, eyeing him as he passed on his way to the lower deck. Steenameert's pink face was carefully impassive, but Toller knew his recent moodiness had had its effect on the youngster, who had developed an intense loyalty to him since they had left their home world. Toller halted him by raising a hand.

"There is no need for you to fret," he said. "I have no intention of hurling myself over the side."

Steenameert looked puzzled. "Sir?"

"Don't play the innocent with me, young fellow." Toller was only two years older than the sergeant, but he spoke in the same kind of fatherly tones that Trye Kettoran often used to him, consciously trying to borrow some of the commissioner's steadiness and stoicism. "I've become the butt of quite a few jests around the base, haven't I? The word has gone about that I'm so besotted with a certain lady that I scarcely know night from day."

The bloom on Steenameert's smooth cheeks deepened and he lowered his voice so as not to be overheard by Correvalte who was nearby at the airship's controls. "Sir, if anybody dared speak ill of you in my presence I would…"

"You will not be required to do battle on my behalf," Toller said firmly, addressing his wayward inner self as much as anybody else, then saw that Steenameert's attention had been drawn elsewhere.

The sergeant spoke quickly, before Toller could frame a question. "Sir, I think we are receiving a message."

Toller looked aft in the direction of Ro-Atabri and saw that a point of intense brilliance was winking amid the complex layered bands of the city. He immediately began deciphering the sunwriter code and felt a peculiar thrill, an icy mingling of excitement and apprehension, as he realized that the beamed message concerned him.

By the time Toller got back to base the balloon of the skyship was fully inflated and the craft was straining at its anchor link, ready to depart for Overland. It was swaying a little within the three timber walls of the towering enclosure, like a vast sentient creature which was becoming impatient with its enforced inactivity. A further indication of the urgency of the situation was that Sky-commodore Sholdde was waiting for Toller by the enclosure instead of in his office.

He nodded ungraciously, obviously in a foul temper, as Toller—flanked by Correvalte and Steenameert—approached him at a quick march and saluted. He ran his fingers through his cropped iron-grey hair and scowled at Toller.

"Captain Maraquine," he said, "this is a cursed inconvenience. I've already been deprived of one airship captain—and now I have to find another."

"Lieutenant Correvalte is perfectly capable of taking my place on the round-the-world flight, sir," Toller replied. "I have no hesitation in recommending him for an immediate field promotion."

"Is that so?" Sholdde turned a hard-eyed, critical gaze on Correvalte and the look of gratification which had appeared on the lieutenant's face quickly faded.

"Sir," Toller said, "is Commissioner Kettoran very ill?"

"He looks to me like he's already dead," Sholdde said indifferently. "Why did he particularly ask for you to fly him home?"

"I don't know, sir."

"I can't understand it either. It seems a strange choice to me. You haven't exactly distinguished yourself on this mission, Maraquine. I kept waiting for you to trip over that antiquated piece of iron you insist on wearing."

Toller unconsciously touched the haft of his sword and he felt his face grow warm. The commodore was subjecting him to unnecessary ignominy by giving him a dressing down in the presence of lesser ranks. The most Toller could do to register a protest was to hint that he viewed Sholdde's remarks as a waste of valuable time.

"Sir, if the commissioner looks as poorly as you say…"

"All right, all right, begone with you." Sholdde glanced briefly at Steenameert. "Has this man become a Maraquine family retainer, part of your personal entourage?"

"Sir, Corporal Steenameert is a first-class skyman and his services would be invaluable to me on—"

"Take him!" Sholdde turned and strode away without any kind of salute, an action which could only be interpreted as another direct insult.

So that's it, Toller thought, alerted by the commodore's reference to the "Maraquine family". My grandfather was the most famed warrior in Kolcorronian history; my father is one of the most brilliant and most powerful men alive—and even the likes of Sholdde resent me for it. Is that because they believe I secretly make use of family influence? Or is it because, by overtly not making use of it, I proclaim a special kind of egotism? Or can it be that I shame or annoy them by refusing to grasp opportunities for which they would give…?

A prolonged blast on the skyship's burner, echoing in the huge cavity of the balloon, interrupted Toller's reverie. He touched Correvalte's shoulder in farewell, ran with Steenameert to the gondola and climbed over the side. The ground crew sergeant who was at the burner controls, keeping the ship in readiness, saluted and nodded towards the passenger compartment.

Toller went to the chest-high cane partition and looked over it. Commissioner Kettoran was lying on a pallet and, in spite of the heat, was covered with a quilt. His long face was extremely pale, with lines of age and weariness graven into it, but his eyes were alert. He winked when he saw Toller and twitched a thin hand in an attempted greeting.

"Are you travelling alone, sir?" Toller said with concern. "No physician?"

A scornful expression briefly animated Kettoran's features. "Those blood-letters will never get their hands on me."

"But if you are ill…"

"The doctor who could cure my complaint has yet to be born," Kettoran said, almost with satisfaction. "I suffer from nothing less than a dearth of time. Speaking of which, young Maraquine, I was under the impression you also were anxious to make a speedy return to Overland."

Toller mumbled an apology and turned to the sergeant, who immediately moved away from the burner controls and clambered over the gondola's side. Pausing for a few seconds on the outside ledge, he explained to Steenameert where all necessary provisions, including skysuits, had been stored. As soon as he had dropped out of sight Toller fed a plentiful charge of hot gas into the pliable dome of the balloon above him and pulled the anchor link.

The skyship surged upwards, its acceleration enhanced by the lift created as the curved upper surface of the balloon moved into the current of air flowing over the enclosure. Well aware that the extra buoyancy would be cancelled as soon as the balloon fully entered the westerly airstream and began to move with it, Toller kept the burner going. The skyship—in spite of being so much below its maximum operating weight—performed a queasy slow-motion shimmy as it adapted to the changing aerial environment, causing Steenameert to clutch theatrically at his stomach. From Commissioner Kettoran, hidden behind his wicker partition, came a moan of complaint.

For the second time in less than an hour the sprawling panorama of Ro-Atabri began to recede from Toller, but now it was retreating downwards. I can scarcely believe that all this is happening to me, he thought dreamily, almost stupefied by the flux of circumstance. Only minutes earlier he had been racked by fears that he would never see Vantara Dervonai again—now he was on his way to her, keeping an appointment which had been specially arranged for him by the forces of destiny.

Soon I will be able to see Vantara again, he told himself. For once, things are working out in my favour.

Toller had not eaten anything for a day, and had taken only a few sips of water, barely enough to replace the bodily moisture lost by exhaling into the arid air of the middle passage. Toilet facilities on a skyship were necessarily primitive and unpleasant to use at the best of times, but in weightless conditions the disadvantages—including the sheer indignity—were so great that most people chose to suspend their natural functions as completely as possible for a day on either side of turnover. The system worked reasonably well for a healthy adult, but Commissioner Kettoran had begun the voyage in a severely weakened state, and now—much to Toller's concern—appeared to be using up the last dregs of his strength merely to stay alive.

"You can take those slops away from me," Kettoran said in a grouchy whisper. "I refuse to be suckled like a babe at my time of life—especially from a revolting dug like that."

Toller unhappily fingered the conical bag of luke-warm soup he had been proffering. "This will do you good."

"You sound just like my mother."

"Is that a reason for not taking sustenance?"

"Don't try to be clever, young Maraquine." Kettoran's breath issued in white clouds from a small opening in the mound of quilts in which he had ensconced himself.

"I was only trying to—"

"My mother could make much better food than any of the cooks we ever employed," Kettoran mused, paying no heed to Toller. "We had a house on the west side of Greenmount—not far from where your grandfather lived, incidentally—and I can still remember riding up the hill, going into our precinct and knowing immediately, just by the aromas, whether or not my mother had chosen to prepare the evening meal. I went back there a few days after we landed in Ro-Atabri, but the entire district had been burnt out a long time ago … during the riots … gutted … hardly a building left intact. It was a mistake for me to go there—I should have preserved my memories."

At the mention of his namesake Toller's interest picked up. "Did you ever see my grandfather in those days?"

"Occasionally. It would have been hard not to see him—a fine figure of a man, he was—but I more often saw his brother, Lain … going back and forth between his house and the Lord Philosopher's official residence in Greenmount Peel."

"What did my grand—?" Toller broke off, alarms clamouring silently in his mind, as there was a subtle but abrupt change in his environment. He rose to his feet, holding a transverse line to keep himself from drifting clear of the deck, and looked all about him. Steenameert, muffled in his skysuit, was strapped into his seat at the control station. He was firing the main jet in the steady rhythm needed to maintain the ship's ascent, and he appeared completely unperturbed. Everything seemed absolutely as normal in the square microcosm of the gondola, and beyond its rim the familiar patterns of stars and luminous whirls shone steadily in the dark blue sky.

"Sir?" The swaddled, anonymous bulk of Steenameert moved slightly. "Is there something wrong?"

Toller had to survey his surroundings again before he was able to identify the source of his unease. "The light! There was a change in the light! Didn't you notice?"

"I must have had my eyes closed. But I still don't…"

"There was a drop in brightness—I'm sure of it—and yet we have more than an hour till nightfall." Baffled and disturbed, wishing he could have a direct view of the sun, Toller drew himself closer to the control station and looked up through the mouth of the balloon. The varnished linen of the envelope was dyed dark brown so that it would absorb heat from the sun, but it was to some extent translucent and he could see a geometrical design of panel seams and load tapes radiating from the crown, emphasizing the vastness of the flimsy dome. It was a sight he had seen many times, and on this occasion it looked exactly as it had always done. Steenameert also looked into the balloon, then lowered his gaze without comment.

"I tell you something happened," Toller said, trying to keep any hint of uncertainty out of his voice. "Something happened. There was a change in the light … a shadow … something."

"According to the height gauge we are somewhere close to the datum plane, sir," Steenameert said, obviously striving to be helpful. "Perhaps we have come up directly beneath the permanent stations and have touched their shadows."

"That is virtually impossible—there is always a certain amount of drift." Toller frowned for a moment, coming to a decision. "Rotate the ship."

"I … I don't think I'm ready to handle an inversion."

"I don't want it turned over yet. Just make a quarter-rotation so that we can see what's above us." Realizing he was still holding the food bag he tossed it towards the passenger compartment on a descending curve. It fouled a safety line, swung round it and floated out over the gondola's side, slowly tumbling as it went.

Toller pulled himself to the rail, straining to see upwards, and waited impatiently while Steenameert fired one of the tiny lateral jets on the opposite side of the gondola. At first the jet appeared to be having no effect, except that the slim acceleration struts on each side of Toller emitted faint creaks; then, after what seemed an interminable wait, the whole universe began a ponderous downwards slide. The whorled disk of Land moved out of sight beneath Toller's feet, and above him—stealthily uncovered by the ship's balloon—there came into view a spectacle unlike anything he had ever seen.

Half the sky was occupied by a vast circular sheet of white fire.

The sun was slipping out of sight behind the eastern edge, and at that point the brilliance was intolerable, a locus of blinding radiance which sprayed billions of prismatic needles across the rest of the circle.

There was a slight falling off in the intensity of light across the disk, but even at the side farthest from the sun it was enough to sting the eyes. To Toller the effect was akin to looking upwards from the depths of a sunlit frozen lake. He had expected to see Overland filling a large area of the heavens, but the planet was hidden behind the beautiful, inexplicable, impossible sheet of diamond-white light, through which rainbow colours raced and danced in clashing zigzag lines.

As he stood at the rail, transfixed, he became aware that the incredible spectacle was drifting down the sky at undiminished speed. He turned and saw that Steenameert was staring out past him, jaw sagging, with eyes which had become reflective white disks—miniature versions of the phenomenon which was mesmerizing him.

"A quarter turn I told you," Toller bellowed. "Check the rotation."

"Sorry, sir." Steenameert stirred into action and the lateral jet mounted low down on Toller's side of the gondola began to spew miglign gas. Rings of condensation rolled away from it through the gelid air. The sound of the jet was puny, quickly absorbed by the surrounding void, but it gradually achieved the intended effect and the skyship came to rest with its vertical axis parallel to the sea of white fire.

"What's going on out there?" The querulous voice of Trye Kettoran issuing from the passenger compartment helped bring Toller out of his own tranced condition.

"Have a look over the side," he called out for the commissioner's benefit, then turned to Steenameert. "What do you think yonder thing is? Ice?"

Steenameert nodded slowly. "Ice is the only explanation I can imagine, but…"

"But where did the water come from? There is the usual supply of drinking water in the defence stations, but that amounts to no more than a few barrels…" Toller paused as a new thought struck him. "Where are the stations, anyway? We must try to locate them. Are they embedded in the…?" His voice failed altogether as related questions geysered through his mind. How thick was the ice? How far away from the ship was it? How wide was the enormous circular sheet?

How wide is the circle?

The last question suddenly reverberated in his consciousness, excluding all others. Until that instant Toller had been overawed by the brilliant spectacle confronting him, but it had inspired no sense of danger. There had been a feeling of wonder—but no threat. Now, however, certain facts of aerial physics were beginning to assume importance. A disturbing importance. A potentially lethal importance…

He knew that the atmosphere which enveloped the sister planets was shaped like an hourglass, the waist of which formed a narrow bridge of air through which skyships had to pass. Old experiments had established that ships had to keep near the centre of the bridge—otherwise the air became so attenuated that the crews were bound to asphyxiate. Largely because of the difficulty of taking measurements in the region, there was some uncertainty about the thickness of that core of breathable air, but the best estimates were that it was no more than a hundred miles in diameter.

The enigmatic sea of sun-blazing ice was rendered featureless by its brilliance, and in the absence of spatial referents it could have been hovering "beside" the skyship at a distance of ten miles, or twenty, or forty, or … Toller could think of no way to ascertain its distance, but he could see that it spanned almost one third of the visual hemisphere, and that gave him enough information to perform an elementary calculation.

Lips moving silently, he stared at the radiant disk while he dealt with the relevant figures, and a coldness which had nothing to do with the harsh environment entered his system as he reached a conclusion. If the disk proved to be as much as sixty miles away—which it could quite easily be—then, by the immutable laws of mathematics, it was sufficiently wide to block the air bridge between Land and Overland…

"Sir?" Steenameert's voice seemed to come from another universe. "How far would you say we are from the ice?"

"That is an excellent question," Toller said grimly, taking the ship's binoculars from the control station locker. He aimed them at the disk, striving to pick out detail, but could see only a shimmering field of brightness. The sun was now fully occulted, spreading its light more evenly over the vast circle, making an estimate of its distance more difficult than before. Toller turned away from the rail, knuckling round green after-images from his eyes, and examined the height gauge. Its pointer was perhaps a hair's breadth below the zero-gravity mark.

"You can't rely much on those devices, sir," Steenameert commented, unable to resist showing off his knowledge. "They are calibrated in a workshop, with no allowance for the effect of low temperatures on the springs, and—"

"Spare me," Toller cut in. "This is a serious matter—I need to know the size of that … thing out there."

"Fly towards it and take note of how it expands."

Toller shook his head. "I have a better idea. I have no intention of turning back unless all other options are denied me—therefore we will fly towards the edge of the circle. Its exact diameter in miles is not all that significant. The truly important thing is to ascertain whether or not we can fly our ship around the obstacle.

"Do you wish to remain at the controls?"

"I would value the experience, sir," Steenameert replied. "What burner rhythm do you require?"

Toller hesitated, frowning, frustrated by the fact that no practicable air speed indicator had ever been developed for use on skyships. An experienced pilot could get some idea of his speed from the slackening of the rip line as the crown of the balloon was depressed by air resistance, but the abundance of variables made accuracy impossible. It would not have been beyond Kolcorronian ingenuity to devise a reliable instrument, but the motivation had never been present. A skyship's job was to crawl up and down between the planetary surface and the weightless zone—a journey which always took roughly five days on each leg—and a difference of a few miles an hour was neither here nor there.

"Give it two and six," Toller said. "We shall pretend to ourselves that we are making twenty miles in the hour and base all our estimates accordingly."

"But what is the nature of the barrier?" Commissioner Kettoran said from close behind Toller. He was in an upright position, holding the edge of the cane partition with one hand and keeping a quilt around him with the other.

Toller's first impulse was to request him to lie down again to achieve the complete rest which had been prescribed by the base physician, then it occurred to him that in the absence of weight it made no difference which attitude was adopted by a person with a heart condition. Allowing his thoughts to be diverted into irrelevancies, he visualized a new use for the pathetic little group of defence stations in the weightless zone. Properly heated and supplied with good air, they could best serve as rest centres for those with certain kinds of ailment. Even a cripple would be…

"I'm addressing you, young Maraquine," Kettoran said peevishly. "What is your opinion of that curious object?"

"I think it might be made of ice."

"But where would such a vast quantity of water come from?"

Toller shrugged. "We have had rocks and even pieces of metal descend on us from the stars—perhaps the void also contains water."

"A likely story," Kettoran grumbled. He gave a theatrical shrug and his long, solemn face—now purple with the cold—slowly sank from view as he returned to his cocoon of downy quilts.

"It's an omen," he added, his voice muffled and indistinct from behind the partition. "I know an omen when I see one."

Toller nodded, smiling thinly in scepticism, and returned to his vigil at the gondola's rail. By calling out-the firing times for the various lateral jets he helped Steenameert guide the ship into a course which closed with the fire-sheet at an unknown angle, aiming it for the westernmost edge. The main jet was roaring in a steady two-six rhythm and Toller knew that the ship's speed could easily be as much as his putative twenty miles an hour—but the aspect of the sheet did not alter noticeably with the passing of the minutes.

"Our friend, the omen, appears to be a veritable giant," he said to Steenameert. "We may have some trouble in getting around him."

Wishing he had the simple navigational instruments available on the humblest airship, Toller kept his gaze on the eastern rim of the great circle, willing it to descend and thus prove that the ship was making significant progress. He was just beginning to convince himself that he could indeed see a change in the vital angle, when the glowing sheet was swept by waves of prismatic colour. They moved at breathtaking orbital speed, crossing the entire disk in mere seconds and stilling Toller's heart with their message that cosmic events were taking place, reminding him of how unimportant the affairs of mankind were when measured against the grandeur of the universe. The sun, already hidden from his view by the icy screen, was being further occulted by Overland. As soon as the bands of colour—engendered by the refraction of the sun's light in Overland's atmosphere—had fled into infinity the disk's overall luminosity began to decrease. Night was falling in the weightless zone.

Here, so close to the datum plane, the terms "night" and "littlenight" no longer had any relevance. Each diurnal cycle was punctuated by two periods of darkness approximately equal in length, and Toller knew it would be some four hours before the sun reappeared. The hiatus could hardly have come at a more inconvenient time.

"Sir?" Steenameert, a sentient pyramid of swaddling in the fading light, had no need to voice the full question.

"Keep going, but reduce thrust to one and six," Toller ordered. "We can shut down the jet altogether if we find we can't keep a check on our course. And be sure to keep the balloon well inflated."

Grateful for Steenameert's competence, Toller remained at the rail and studied the disk. Sunlight was still being reflected from Land—which was now directly behind him—so the icy wall remained visible, and with the change in illumination he began to see hints of an internal structure. There was a tracery of the palest violet, arranged like rivers which divided and kept on dividing until they faded from the sight, lost in distant shimmers.

They're like veins, Toller thought. Veins in a giant eye…

As Land was gradually enveloped in Overland's shadow the disk steadily darkened to near-blackness, but its edge was still clearly defined against the cosmic background. The rest of the sky was now ablaze with its customary extravagance of galaxies—glowing whirlpools ranging from circles to slim ellipses—plus formless ribbons of light, myriads of stars, comets and darting meteors. Against that luminous richness the disk was more mysterious than ever—a featureless well of night which had no right to exist in a rational universe.

By occasionally ordering a slight pendulum movement of the ship Toller was able to look ahead and satisfy himself that it was on course for the disk's western edge. As the hours of darkness dragged by the air became progressively thinner and less satisfying to the lungs, evidence that the skyship was far from the centre of the invisible bridge that linked the two worlds. Although Commissioner Kettoran did not voice any complaint, his breathing became clearly audible. He had mixed some firesalt with water in a vellum bag and could be heard sniffing from it at frequent intervals.

When at last daylight returned, heralded by a brightening of the disk's western rim, Toller found he could see the rim without having to tilt the ship. Perspective returned; geometry again became a useful tool.

"We're only a mile or so from the edge," he announced for the benefit of Steenameert and Kettoran. "In a few minutes we should be able to work around it and head back into the good air."

"It's about time!" Kettoran scowled face appeared above the passenger compartment partition. "How far to the side have we travelled?"

"Perpendicular to the ideal course, we must have done in the region of thirty miles—" Toller glanced at Steenameert and received a nod of confirmation—"which means we are dealing with a lake, a sea, of ice some sixty miles across. I find it hard to credit what I'm saying, even though I am looking straight at the thing. Nobody in Prad is going to believe what we say."

"We may have corroboration."

"By telescope?"

"By your lady friend—Countess Vantara." Kettoran dabbed a drop of moisture from the end of his nose. "Her ship departed not so many days before ours."

"You're right, of course." Toller was dully surprised to realize he had forgotten about Vantara for several hours. "The ice … the barrier … whatever it is … may have been in place when she made the crossing. It is something we will have to confer over in detail."

Having derived an unexpected grain of comfort from the discussion—a readymade reason to seek out Vantara, wherever she might be—Toller gave his attention to the task of steering his ship around the edge of the disk. The manoeuvre was not a difficult one in theory. AH he had to do was pass the western rim by a short distance, carry out a simple inversion and begin flying back into the thicker air at the core of the atmospheric bridge.

Leaving Steenameert at the controls, he remained by the rail in order to obtain the most advantageous viewpoint and started giving detailed handling instructions. The ship was moving very slowly as it drew level with the rim, probably at no more than walking pace, but after some minutes had passed it came to Toller that it was taking longer than he had expected to reach the limit of the ice wall. Suddenly suspicious, he trained his binoculars on the rim. The sun was close to his aiming point, hurling billions of needles of radiance into his eyes and making the viewing difficult, but he managed to get a clear look at the icy boundary. It was now less than a furlong away in reality, and the image in his glasses brought it much closer.

Toller grunted in surprise as he discovered that the rim of the ice sheet was alive.

In place of what he had expected—the inertness of frozen water—there was a kind of crystalline seething. Glassy prisms and spikes and branches, each as tall as a man, were sprouting outwards on the rim with unnatural rapidity. They were extending the boundary of the sheet with the speed of billowing smoke—each thrusting into the gelid air and glistening in the sunlight for a moment before being overtaken and assimilated by others in the racing, sparkling vitreous foment.

Toller stared at the phenomenon, tranced, his mind awash with the unexpected and incredible beauty of it, and it seemed a long time before the first coherent thought came to him: The rim of the barrier is moving outwards at almost the same speed as the ship!

"Increase speed," he shouted to Steenameert, his voice strained by the bitter coldness and the inimical nature of the thinning air. "Otherwise you'll never see home again!"

Commissioner Kettoran, who had seemed almost a well man during the passage through the weightless zone, had been struck by a fresh seizure when the ship was only a few thousand feet above the surface of Overland. In one second he had been standing with Toller at the gondola's rail and pointing out familiar features in the landscape below; in the next he was lying on his back, unable to move, eyes alert and afraid, beaconing an intelligence trapped inside a machine which no longer responded to its master's bidding. Toller had carried him to his nest of quilts, wiped the frothy saliva from the corners of his mouth, and had gone immediately for the sunwriter in its leather case.

The lateral drift had been greater than usual, bringing the ship down some twelve miles to the east of the city of Prad, but the sunwriter message had been picked up in good time. A sizeable group of coaches and mounted men—plus a sleek airboat in grey-and-blue royal livery—had been waiting in the touchdown area. Within five minutes of the landing the commissioner had been transferred to the airboat and sent on his way to an emergency audition with Queen Daseene, who was waiting in the overheated confines of her palace.

There had been no opportunity for Toller to pass on any words of reassurance or farewell to Kettoran, a man he had come to regard as a good friend in spite of the disparity in age and status. As he watched the airboat dwindle into the yellow western sky he became aware of a sense of guilt and it took him some time to identify its source. He was, of course, deeply concerned about the commissioner's health, but at the same time—and there was no getting around the fact—one part of him was thankful that the older man's misfortune had come along, like the answer to a prayer, exactly when he had needed it. No other circumstance that he could readily think of could have placed him back on Overland and within reach of Vantara in such a short time.

What sort of monster am I? he thought, shocked by his own selfishness. I must be the worst…

Toller's bout of introspection was interrupted by the sight of his father and Bartan Drumme descending from a coach which had just arrived at the landing site. Both men were attired in grey trews and three-quarter-length tabards gored with blue silk, a formal style of dress which suggested they had come straight from an important meeting in the city. Toller strode eagerly to meet his father, embraced him and then shook hands with Bartan Drumme.

"This is truly an unexpected pleasure," Cassyll Maraquine said, a smile rejuvenating his pale triangular face, "it is a great shame about the commissioner, of course, but we must assume that the royal physicians—a plentiful breed in these times—will quickly put him to rights. How have you been, son?"

"I am well." Toller looked at his father for a moment in that unique gratification which springs from an harmonious relationship with a parent, and then—as extraneous matters crowded into his mind—he shifted his gaze to include Bartan Drumme in what had to follow. The latter was the only surviving member of a fabled voyage to Farland, the local system's outermost planet, and was acknowledged as Kolcorron's leading expert on astronomical matters.

"Father, Bartan," Toller said, "have you been observing the skies within the last ten or twenty days? Have you noticed anything unusual?"

The older men exchanged cautiously surprised glances. "Are you speaking of the blue planet?" Bartan said.

Toller frowned. "Blue planet? No, I'm talking about a barrier … a wall … a lake of ice … call it what you will … which has appeared at the midpoint. It is at least sixty miles across and growing wider by the hour. Has it not been observed from the ground?"

"Nothing out of the ordinary has been observed, but I'm not even sure that the Glo telescope has been in use since—" Bartan broke off and gave Toller a quizzical stare. "Toller … Toller, you can't have an accretion of ice at the midpoint—there simply isn't the water. The air is too dry."

"Ice! Or crystal of some kind. I saw it!" The fact that he was being disbelieved did not surprise or unduly disturb Toller, but it caused an uneasy stirring in the lower levels of his consciousness. There was something wrong with the pattern of the conversation. It was not going as it should have gone, but some factor—perhaps a deep-seated unwillingness to face reality—was for the moment paralyzing vital mental processes.

Bartan gave him a patient smile. "Perhaps there has been a major failure in one of the permanent stations, perhaps an explosion which has scattered power crystals over a wide area. They might be drifting and combining and forming large clouds of condensation, and we both know that condensation can give the appearance of being very substantial … like banks of snow or—"

"The Countess Vantara," Toller interrupted with a numb smile, keeping his voice steady to hide the fear that had been unleashed in him as certain doors swung open. "She made the crossing only nine days ago—had she nothing unusual to report?"

"I don't know what you mean, son," Cassyll Maraquine said, speaking the words which Toller had already prepared for him on a parchment of the mind. "Yours is the first and only ship to have returned from Land. Countess Vantara has not been seen since the expedition departed."
