Leddravohr was mentally tired after the meeting and had been hoping to relax during dinner, but his father — with the abundant cerebral energy which characterises some elderly men — talked all the way through the meal. He switched rapidly and effortlessly from military strategy to food rationing schemes to the technicalities of interworld flight, displaying his fascination with detail, trying to explore mutually incompatible probabilities. Leddravohr, who had no taste for juggling with abstracts, was relieved when the meal was finished and his father moved out to the balcony for a final cup of wine before retiring to his private quarters.

“Damn this glass,” Prad said, tapping the transparent cupola which enclosed the balcony. “I used to enjoy taking the air here at night. Now I can scarcely breathe.”

“Without the glass you wouldn’t be breathing at all.” Leddravohr flicked his thumb, indicating a group of three ptertha drifting overhead across the glowing face of Overland. The sun had gone down and now the sister world was entering the gibbous phases of its illumination, casting its mellow light over the southern reaches of the city, Arle Bay and the deep indigo expanses of the Gulf of Tronom. The light was good enough to read by and would steadily increase in strength as Overland, keeping pace with the rotation of Land, swung towards its point of opposition with the sun. Although the sky had darkened only to a rich mid-blue the stars, some of which were bright enough to be visible in full daylight, formed blazing patterns from Overland’s rim down to the horizon.

“Damn the ptertha, too,” Prad said. “You know, son, one of the greatest tragedies of our past is that we never learned where the globes come from. Even if they are spawned somewhere in the upper atmosphere, it might have been possible at one time to track them down and destroy them at source. It’s too late now, though.”

“What about your triumphant return from Overland? Attacking the ptertha from above?”

“Too late for me, I mean. History will remember me for the outward flight only.”

“Ah, yes — history,” Leddravohr said, once again wondering at his father’s preoccupation with the pale and spurious immortality offered by books and graven monuments. Life was a transient thing, impossible to extend beyond its natural term, and time spent in trying to do so was a squandering of the very commodity one was seeking to preserve. Leddravohr’s own belief was that the only way to cheat death, or at least reconcile oneself to it, was to achieve every ambition and sate every appetite, so that when the time came the relinquishing of life was little more than discarding an empty gourd.

His single overriding ambition had been to extend his future kingship to every quarter of Land — including Chamteth — but that was now denied him by a connivance of fate. In its place was the prospect of a hazardous and unnatural flight into the sky, followed by little more than a tribal existence on an unknown world. He was angry about that, filled with a gnawing canker of rage unlike anything he had ever known, and somebody would have to pay.…

Prad sipped pensively at his wine. “Have you prepared all your dispatches?”

“Yes — the messengers leave at first light.” Leddravohr had spent all his free time after the meeting personally writing orders to the five generals he wanted for his staff. “I instructed them to use continuous thrust, so we should have distinguished company quite soon.”

“I take it you have chosen Dalacott.”

“He’s still the best tactician we have.”

“Aren’t you afraid that his edge might be blunted?” Prad said. “He must be seventy now, and being down in Kail when the plague broke out there can’t have done him much good. Didn’t he lose a daughter and a grandchild on the very first day?”

“Something like that,” Leddravohr replied carelessly. “He is still healthy, though. Still of value.”

“He must have the immunity.” Prad’s face became more animated as he fastened on to yet another of his talking points. “You know, Glo sent me some very interesting statistics at the beginning of the year. They were collated by Maraquine. They showed that the incidence of plague deaths among military personnel — which you would expect to be high because of their exposure — is actually somewhat lower than for the population in general. And, significantly, long-serving soldiers and airmen are the least likely to succumb. Maraquine suggested that years of being near ptertha kills and absorbing minute traces of the dust might train the body to resist pterthacosis. It’s an intriguing thought.”

“Father, it’s a totally useless thought.”

“I wouldn’t say that. If the offspring of immune men and women were also immune, from birth, then you could breed a new race for whom the globes were no threat.”

“And what good would that be fo you and me?” Leddravohr said, disposing of the argument to his own satisfaction. “No, as far as I’m concerned Glo and Maraquine and their ilk are ornaments we can well do without. I look forward to the day when.…”

“Enough!” His father was suddenly King Prad Neldeever, ruler of the empire of Kolcorron, tall ainl rigid, with one terrible blind eye and one equally fearsome all-seeing eye which knew everything Leddravohr would have wished to keep secret. “Ours will not be the house which is remembered for turning its back on learning. You will give me your word that you will not harm Glo or Maraquine.”

Leddravohr shrugged. “You have my word.”

“That came easily.” His father stared at him for a moment, dissatisfied, then said, “Neither will you touch Maraquine’s brother, the one who now attends to Glo.”

“That oaf! I have more important things with which to occupy my mind.”

“I know. I have given you unprecedented powers because you have the qualities necessary to bring a great endeavour to a successful conclusion, and that power is not to be abused.”

“Spare me all this, father,” Leddravohr protested, laughing to conceal his resentment at being admonished like a wilful child. “I intend to treat our philosophers with all the consideration they deserve. Tomorrow I’m going to Greenmount for two or three days — to learn all I need to know about their skyships — and if you care to make enquiries you’ll hear that I am emanating nothing but courtesy and love.”

“Don’t overdo it.” Prad drained his cup with a flourish, set it down on the wide stone balustrade and prepared to leave. “Good night, son. And remember — the future watches.”

As soon as the King had departed Leddravohr exchanged his wine for a glass of fiery Padalian brandy and returned to the balcony. He sat down on a leather couch and gazed moodily at the southern sky where three great comets plumed the star fields. The future watches! His father was still cherishing the notion of going down in history as another King Bytran, blinding himself to the probability that there would be no historians to record his achievements. The story of Kolcorron was drawing to a bizarre and ignominious end just when it should have been entering the most glorious era of all.

And I’m the one who is losing most, Leddravohr thought. I’m never going to be a real King.

As he continued drinking brandy, and the night grew steadily brighter, it came to Leddravohr that there was an anomaly in the contrast between his attitude and that of his father. Optimism was the prerogative of the young, and yet the King was looking to the future with confidence; pessimism was a trait of the old, and yet it was Leddravohr who was gloomy and prey to grim forebodings. Why?

Was it that his father was too wrapped up in his enthusiasm for all things scientific to concede that the migration was impossible? Leddravohr took stock of his thoughts and was forced to discard the theory. At some stage in the day-long meeting he had been persuaded by the drawings, the graphs and the chains of figures, and now he believed that a skyship could reach the sister world. What, then, was the underlying cause of the malaise which had entered his soul? The future was not completely black, after all — there was the final war with Chamteth to anticipate.
