By the tenth day of the flight the ship was only a thousand miles above the surface of Overland, and the ancient patterns of night and day had been reversed.

The period Toller still tended to think of as littlenight — when Overland was screening out the sun — had grown to be seven hours in length; whereas night — when they were in the shadow of the home world — now lasted less than half that time. He was sitting alone at the pilot’s station, waiting for daybreak and trying to foresee his people’s future on the new world. It seemed to him that even native Kolcorronians, who had always been accustomed to living directly below the fixed sphere of Overland, might feel oppressed by the sight of a larger planet suspended directly above them and depriving them of a proportionately greater part of their day. Assuming Overland to be uninhabited, the migrants could be disposed towards building their new nation on the far side of the planet, in latitudes corresponding to those of Chamteth on Land. Perhaps a time would come when all memory of their origins had faded and.…

Toller’s thoughts were interrupted by the appearance of Chakkell’s seven-year-old son, Setwan, at the entrance to their compartment. The boy came to his side and leaned his head on Toller’s shoulder.

“I can’t sleep, Uncle Toller,” he whispered. “May I stay here with you?”

Toller lifted the boy on to his knee, smiling to himself as he visualised Daseene’s reaction if she heard one of her children address him as uncle. Of the seven people confined to the punishing microcosm of the gondola, Daseene was the only one who had made no concessions to their situation. She had not spoken to Toller or Gesalla, still wore her pearl coif, and ventured out of the passenger compartment only when it was absolutely necessary. She had gone without food or drink for three whole days rather than submit to the ordeal of using the primitive toilet when near the midpoint of the voyage. Her features had become pale and pinched, and — although the ship had since descended to warmer levels of Overland’s atmosphere — she remained huddled in the quilted garments which had been hastily manufactured for the migration flight. She answered in monosyllables when spoken to by her family.

Toller had a certain sympathy for Daseene, knowing that the traumas of recent days had been greater for her than for any of the others on board. The children — Corba, Oldo and Setwan — had not had enough years in the privileged dreamland of the Five Palaces to condition them irrevocably, and they had a natural sense of curiosity and adventure on their side. Chakkell’s responsibilities and ambitions had always kept him fully in touch with the everyday realities of life in Kolcorron, and he had sufficient strength and resourcefulness to let him anticipate a key role in the founding of a new nation on Overland. Indeed Toller had been quite impressed by the way in which the prince, after the initial period of adjustment, had chosen to involve himself with the operation of the ship without shirking any task.

Chakkell had been particularly scrupulous as regards taking long spells at the microjets which gave the ship some control over its lateral position. It was expected and accepted that all other ships of the fleet would be dispersed by air currents over quite a large area of Overland after a journey of five-thousand miles, but Leddravohr had decreed that the royal flight should be able to land in a tight group.

Different methods of tethering the four ships had been dismissed as impracticable, and in the end they had been fitted with miniature horizontal jets delivering only a small fraction of the thrust produced by the attitude control jets. When fired continuously for a long time they added a very slight lateral component to a ship’s vertical motion, without causing it to rotate around its centre of gravity, and assiduous use of them had kept the four royal ships in close formation throughout the flight.

The proximity of the others had furnished Toller with one of the most memorable spectacles of his life, when the group had passed the midpoint and it came time to turn the ships over. Although he had been through the experience before, he found something awesome and ineffably beautiful in the sight of the sister planets majestically drifting in opposite directions, Overland gliding out from the occultation of the balloon and down the sky while Land, at the other end of an invisible beam, climbed above the gondola wall.

And with the transposition half complete a new dimension of wonder was added. A receding, dwindling series of ships seemed to reach all the way to each planet, visible as disks which progressively shrank to glowing points. Several of those going in the direction of Overland had delayed turning over and could be seen from underneath with their gondolas, attachments and jet pipes scribed in ever finer detail on the shrinking circles.

As if that were not enough to brim the eye and mind, there was also — against deep blue infinities seeded with swirls and braids and points of frozen brilliance — the sight of the three companion ships carrying out their own inversion manoeuvres. The structures, which were so fragile that they could be crumpled by a boisterous breeze, remained magically immune to distortion as they stood the universe on its head, proclaiming that this truly was the zone of strangeness. Their pilots, visible as enigmatic mounds of swaddling, surely had to be alien supermen gifted with knowledge and skills inaccessible to ordinary men.

Not all of the scenes witnessed by Toller had possessed such grandeur, but they were imprinted on his memory for different reasons. There was Gesalla’s face in its varied moods and aspects — dubiously triumphant as she overcame the waywardness of the galley fire, wanly introspective after hours of “falling” through the region of zero or negligible gravity… the bursting of all the accompanying ptertha within minutes of each other, after a day of climbing… the children’s looks of astonishment and delight as their breath became visible in the surrounding chill… the games they played during the brief period when they could suspend beads and trinkets in the air to sketch simplified faces and build three-dimensional designs.…

And there had been the other scenes, exterior to the ship, which told of distant tragedies and the kind of death which heretofore had belonged to the realms of purest nightmare.

The royal flight had taken off at quite an early stage in the evacuation of the Quarter, and Toller knew that by the time they were a day and more past the midpoint they had above them an attenuated linear cloud of ships perhaps a hundred miles high. Had they not already been screened from view by the sedate vastness of his own balloon most of them would have been rendered invisible by sheer distance, but he had received disturbing proof of their existence. It took the form of a sparse, spasmodic and dreadful rain. A rain whose droplets were solid and which varied in size, from entire skyships to human bodies.

On three separate occasions he had seen crumpled ships plunge down past him, the gondolas wrapped in the slow-flapping ruins of their balloons, bound on the day-long fall to Overland. It was his guess that all vestiges of order had disappeared during the latter hours of the escape from Ro-Atabri, and that in the chaos some ships had been taken up by inexperienced fliers or had even been commandeered by rebels with no aviation knowledge at all. It looked as though some of them had driven far past the midpoint without turning over, their velocity being augmented by the growing attraction of Overland until the stresses in the flimsy envelopes had torn them apart.

Once he had seen a gondola plummeting down without its balloon, maintaining its proper attitude because of the trailing lines and acceleration struts, and a dozen soldiers had been visible at its rails, mutely surveying the procession of still-airworthy ships which was to be their last tenuous link with humanity and with life.
