“If the dragonets were only larger, Kitti,” Bay broke in, her manner unusually brusque, “intelligent enough to obey commands, they’d be an immense help to us. I was able to use mentasynth to enhance their own latent empathies, but that’s a relatively simple matter. To breed large enough dragonets – dragons – we need them big – ” Bay stretched her arms full length and flicked her fingers to indicate room size. “ – intelligent, obedient, strong enough to do the job needed: flame Thread out of the sky.” She ran out of words then, knowing very well how Kitti Ping Yung felt about bioengineering beyond simple adjustments to adapt creatures to new ecological parameters.
Kitti Ping nodded again while her granddaughter regarded her with surprise. “Yes, size, strength, and considerable intelligence would be required,” she said in her softly audible voice. Hiding her hands in the cuffs of her long sleeves and folding them across her stomach, she bent her head and was silent for so long that her audience wondered if she had nodded off in the easy sleep of the aged. Then she spoke again. “And dedication, which is easy to instill in some creatures, impossible in others. The dragonets already possess the traits you wish to enhance and magnify.” She smiled, a gentle, faintly apologetic smile of great sadness and compassion. “I was the merest student, though a very willing and eager one, in the Great Beltrae Halls of Eridani. I was taught what would happen if I did this or that, enlarged or reduced, severed that synapse or modified the gene pattern. Most of the time what I was taught to do worked, but, alas,” she added, raising one hand warningly, “I never knew why sometimes the modification failed and the organism died. Or should have. The Beltrae would teach us the how but never the why.”
Paul sighed deeply, despair threatening to overwhelm him.
“But I can try,” she said. “And I will. For though my years are nearly accomplished, there are others to be considered.” She turned to smile gently upon Wind Blossom, who ducked her head with humility.
Paul shook his head, not quite believing what she had just said.
“You will?” Bay exclaimed, jumping to her feet. She stopped just short of rushing to Kitti’s raised chair.
“Of course I will try!” Kitti raised one tiny hand in warning. “But I must caution you that success cannot be assumed. What we under take is dangerous to the species, could be dangerous for us, and cannot be guaranteed. It is good fortune of the highest degree that the little dragonets already possess so many of the qualities required in the genetically altered animal that suits the urgent need. Even then we may not be able to achieve the exact creature, or even be sure of a genetic progression. We have no sophisticated laboratory equipment or methods of analysis which could lighten our burden. We must let repetition, the work of many hands and eyes, replace precision and delicacy. The task is appropriate, but the means are barbaric.’’
“But we have to try!” Paul Benden said, rising to his feet with clenched fists.

All medical staff not on duty in the infirmary or on ground crew duty, the veterinarians, and the apprentices, Sean and Sorka included, worked shifts as Kitti Ping’s project was given top priority. Anyone with training in biology, chemistry, or laboratory procedures of any kind – sometimes even those with nimble fingers who could be put to work preparing slides, or those convalescing from Threadfall injuries who could watch monitors – were drafted into service. Kitti, Wind Blossom, Bay, and Pol extracted a genetic code from the chromosomes of the fire-dragonets. Although the creatures were not of Earth, their biology proved not too dissimilar to work with.
“We succeeded with the chiropteroids on Centauri,” Pol said, “and they had chains of silicons as their genetic material.”
A great deal of schedule juggling was required in order to muster enough people to fight Fall over populated areas. The detailed sequence of Threadfall, established by the exhausted team of Boris Pahlevi and Dieter Clissmann, gave a structure to which even Kitti’s project had to bow. The resultant four-shift roster attempted to provide everyone with some time for themselves – both to relax and to care for their own stakes – though some of the specialists ignored such considerations and had to be ordered to sleep.
Everyone over the age of twelve was brought in when Thread fell. The hope that Kenjo, in the Mariposa, could deflect Thread pods in the upper reaches of the atmosphere turned out to be ineffective. The predicted double Fall – over Cardiff in mid-Jordan and Bordeaux in Kahrain, and over Seminole and Ierne Island – was patchy, but the gaps perversely did not include occupied sites.
More double Falls could be anticipated: on the thirty-first day after First Fall, Thread would sweep across Karachi camp and the tip of the Kahrain peninsula; three days later a single land corridor would range from Kahrain across Paradise River Stake, while a second Fall would pass harmlessly at sea well above the tip of Cibola Province. After another three days, a dangerous double would hit Boca Stake and the thick forests of lower Kahrain and Araby, stocks of the one real wood vitally needed to shore up mine pits at busy Karachi Camp and Drake’s Lake.
Ezra spent hours in the booth that housed the link with the Yokohama’s mainframe, scanning the naval and military histories in find some means of combating the menace. He also sought, with much less optimism, obscure equations or devices that might be able to alter the orbit of the planet. Then the next Fall could, perhaps, be avoided. Meanwhile, however, the present pass had seeded Pern’s orbit with spirals of the encapsulated Thread, a danger that the colonists would have to face no matter what. He also did comparisons with data from Kitti’s program, delving into science files, using her security ID to access secret or “need to know” information. He was waiting, too, for the probe’s findings to be relayed back to him. And because everyone knew where to find Ezra, he often intercepted complaints and minor problems that would have added unnecessary burdens to the admiral and the governor.
Kenjo was sent on three more missions, each time trying to find a more efficient way of destroying enough Thread in space to justify the expenditure of precious fuel. The gauges on the Mariposa dropped only slightly with each trip, and Kenjo was commended on his economy. Drake was openly envious of the space pilots skill.
“Jays, man,” Drake would say. “You’re driving it on the fumes.”
Kenjo would nod modestly and say nothing. He was, however, rather relieved that he had not managed to transfer all the fuel sacks to their hiding place at Honshu. All too soon, he would have to broach that supply to ensure continued trips into space. Only there did he feel totally aware and alive in every sense and nerve of his body.
But each time he brought back useful information. Thread,
it turned out, traveled in a pod that burned away when it hit the atmosphere of Pern, leaving an inner capsule. About 15,000 feet above the surface, the inner capsule opened into ribbons, some of which were not thick enough to survive in the upper reaches. But, as everyone at Landing well knew, plenty fell to the surface.
Most of the sleds were unpressurized, so they had an effective ceiling of 10,000 feet. There was still only one way to clear the Thread from the skies: by flame-throwers.
With Thread due to fall on the Big Island Stake on Day 40, Paul Benden ordered Avril Bitra and Stev Kimmer to return to Landing. When Stev asked what Landing needed in the way of the ores mined at Big Island, Joel Lilienkamp was more than happy to supply a list. So when they arrived at Landing with four sleds crammed canopy high with metal ingots, no one mentioned their long delinquency.
