Ela and Novinha would be disappointed--they had had such hopes for this strain of potato. Ela, Ender's stepdaughter, had been working on a gene that would cause every cell in an organism to produce three different chemicals that were known to inhibit or kill the descolada virus. Novinha, Ender's wife, had been working on a gene that would cause cell nuclei to be impermeable to any molecule larger than one-tenth the size of the descolada. With this strain of potato, they had spliced in both genes and, when early tests showed that both traits had taken hold, Ender had brought the seedlings to the experimental farm and planted them. He and his assistants had nurtured them for the past six weeks. All had seemed to be going well.
If the technique had worked, it could have been adapted to all the plants and animals that the humans of Lusitania depended on for food. But the descolada virus was too clever by half--it saw through all their stratagems, eventually. Still, six weeks was better than the normal two or three days. Maybe they were on the right track.
Or maybe things had already gone too far. Back when Ender first arrived on Lusitania, new strains of Earthborn plants and animals could last as long as twenty years in the field before the descolada decoded their genetic molecules and tore them apart. But in recent years the descolada virus had apparently made a breakthrough that allowed it to decode any genetic molecule from Earth in days or even hours.
These days the only thing that allowed the human colonists to grow their plants and raise their animals was a spray that was immediately fatal to the descolada virus. There were human colonists who wanted to spray the whole planet and wipe out the descolada virus once and for all.
Spraying a whole planet was impractical, but not impossible; there were other reasons for rejecting that option. Every form of native life absolutely depended on the descolada in order to reproduce. That included the piggies--the pequeninos, the intelligent natives of this world--whose reproductive cycle was inextricably bound up with the only native species of tree. If the descolada virus were ever destroyed, this generation of pequeninos would be the last. It would be xenocide.
So far, the idea of doing anything that would wipe out the piggies would be immediately rejected by most of the people of Milagre, the village of humans. So far. But Ender knew that many minds would change if a few more facts were widely known. For instance, only a handful of people knew that twice already the descolada had adapted itself to the chemical they were using to kill it. Ela and Novinha had already developed several new versions of the chemical, so that the next time the descolada adapted to one viricide they could switch immediately to another. Likewise, they had once had to change the descolada inhibitor that kept human beings from dying of the descolada viruses that dwelt in every human in the colony. The inhibitor was added to all the colony's food, so that every human being ingested it with every meal.
However, all the inhibitors and viricides worked on the same basic principles. Someday, just as the descolada virus had learned how to adapt to Earthborn genes in general, it would also learn how to handle each class of chemicals, and then it wouldn't matter how many new versions they had--the descolada would exhaust their resources in days.
Only a few people knew how precarious Milagre's survival really was. Only a few people understood how much was riding on the work that Ela and Novinha, as Lusitania's xenobiologists, were doing; how close their contest was with the descolada; how devastating the consequences would be if they ever fell behind.
Just as well. If the colonists did understand, there would be many who would say, If it's inevitable that someday the descolada will overwhelm us, then let's wipe it out now. If that kills all the piggies then we're sorry, but if it's us or them, we choose us.
It was fine for Ender to take the long view, the philosophical perspective, and say, Better for one small human colony to perish than to wipe out an entire sentient species. He knew this argument would carry no water with the humans of Lusitania. Their own lives were at stake here, and the lives of their children; it would be absurd to expect them to be willing to die for the sake of another species that they didn't understand and that few of them even liked. It would make no sense genetically--evolution encourages only creatures who are serious about protecting their own genes. Even if the Bishop himself declared it to be the will of God that the human beings of Lusitania lay down their lives for the piggies, there would be precious few who would obey.
I'm not sure I could make such a sacrifice myself, thought Ender. Even though I have no children of my own. Even though I have already lived through the destruction of a sentient species--even though I triggered that destruction myself, and I know what a terrible moral burden that is to bear--I'm not sure I could let my fellow human beings die, either by starvation because their food crops have been destroyed, or far more painfully by the return of the descolada as a disease with the power to consume the human body in days.
And yet . . . could I consent to the destruction of the pequeninos? Could I permit another xenocide?
He picked up one of the broken potato stems with its blotchy leaves. He would have to take this to Novinha, of course. Novinha would examine it, or Ela would, and they'd confirm what was already obvious. Another failure. He put the potato stem into a sterile pouch.
"Speaker."
It was Planter, Ender's assistant and his closest friend among the piggies. Planter was a son of the pequenino named Human, whom Ender had taken into the "third life," the tree stage of the pequenino life cycle. Ender held up the transparent plastic pouch for Planter to see the leaves inside.
"Very dead indeed, Speaker," said Planter, with no discernible emotion. That had been the most disconcerting thing about working with pequeninos at first--they didn't show emotions in ways that humans could easily, habitually interpret. It was one of the greatest barriers to their acceptance by most of the colonists. The piggies weren't cute or cuddly; they were merely strange.
"We'll try again," said Ender. "I think we're getting closer."
"Your wife wants you," said Planter. The word wife, even translated into a human language like Stark, was so loaded with tension for a pequenino that it was difficult to speak the word naturally--Planter almost screeched it. Yet the idea of wifeness was so powerful to the pequeninos that, while they could call Novinha by her name when they spoke to her directly, when they were speaking to Novinha's husband they could only refer to her by her title.
"I was just about to go see her anyway," said Ender. "Would you measure and record these potatoes, please?"
Planter leaped straight up--like a popcorn, Ender thought. Though his face remained, to human eyes, expressionless, the vertical jump showed his delight. Planter loved working with the electronic equipment, both because machines fascinated him and because it added greatly to his status -among the other pequenino males. Planter immediately began unpacking the camera and its computer from the bag he always carried with him.
"When you're done, please prepare this isolated section for flash burning," said Ender.
"Yes yes," said Planter. "Yes yes yes."
Ender sighed. Pequeninos got so annoyed when humans told them things that they already knew. Planter certainly knew the routine when the descolada had adapted to a new crop--the "educated" virus had to be destroyed while it was still in isolation. No point in letting the whole community of descolada viruses profit from what one strain had learned. So Ender shouldn't have reminded him. And yet that was how human beings satisfied their sense of responsibility--checking again even when they knew it was unnecessary.
Planter was so busy he hardly noticed that Ender was leaving the field. When Ender was inside the isolation shed at the townward end of the field, he stripped, put his clothes in the purification box, and then did the purification dance--hands up high, arms rotating at the shoulder, turning in a circle, squatting and standing again, so that no part of his body was missed by the combination of radiation and gases that filled the shed. He breathed deeply through mouth and nose, then coughed--as always--becau
se the gases were barely within the limits of human tolerance. Three full minutes with burning eyes and wheezing lungs, while waving his arms and squatting and standing: our ritual of obeisance to the almighty descolada. Thus we humiliate ourselves before the undisputed master of life on this planet.
Finally it was done; I've been roasted to a turn, he thought. As fresh air finally rushed into the shed, he took his clothes out of the box and put them on, still hot. As soon as he left the shed, it would be heated so that every surface was far over the proven heat tolerance of the descolada virus. Nothing could live in that shed during this final step of purification. Next time someone came to the shed it would be absolutely sterile.
Yet Ender couldn't help but think that somehow the descolada virus would find a way through--if not through the shed, then through the mild disruption barrier that surrounded the experimental crop area like an invisible fortress wall. Officially, no molecule larger than a hundred atoms could pass through that barrier without being broken up. Fences on either side of the barrier kept humans and piggies from straying into the fatal area--but Ender had often imagined what it would be like for someone to pass through the disruption field. Every cell in the body would be killed instantly as the nucleic acids broke apart. Perhaps the body would hold together physically. But in Ender's imagination he always saw the body crumbling into dust on the other side of the barrier, the breeze carrying it away like smoke before it could hit the ground.
What made Ender most uncomfortable about the disruption barrier was that it was based on the same principle as the Molecular Disruption Device. Designed to be used against starships and missiles, it was Ender who turned it against the home planet of the buggers when he commanded the human warfleet three thousand years ago. And it was the same weapon that was now on its way from Starways Congress to Lusitania. According to Jane, Starways Congress had already attempted to send the order to use it. She had blocked that by cutting off ansible communications between the fleet and the rest of humanity, but there was no telling whether some overwrought ship's captain, panicked because his ansible wasn't working, might still use it on Lusitania when he got here.
It was unthinkable, but they had done it--Congress had sent the order to destroy a world. To commit xenocide. Had Ender written the Hive Queen in vain? Had they already forgotten?
But it wasn't "already" to them. It was three thousand years to most people. And even though Ender had written the Life of Human, it wasn't believed widely enough yet. It hadn't been embraced by the people to such a degree that Congress wouldn't dare to act against the pequeninos.
Why had they decided to do it? Probably for exactly the same purpose as the xenobiologists' disruption barrier: to isolate a dangerous infection so it couldn't spread into the wider population. Congress was probably worried about containing the plague of planetary revolt. But when the fleet reached here, with or without orders, they might be as likely to use the Little Doctor as the final solution to the descolada problem: If there were no planet Lusitania, there would be no self-mutating half-intelligent virus itching for a chance to wipe out humanity and all its works.
It wasn't that long a walk from the experimental fields to the new xenobiology station. The path wound over a low hill, skirting the edge of the wood that provided father, mother, and living cemetery to this tribe of pequeninos, and then on to the north gate in the fence that surrounded the human colony.
The fence was a sore point with Ender. There was no reason for it to exist anymore, now that the policy of minimal contact between humans and pequeninos had broken down, and both species passed freely through the gate. When Ender arrived on Lusitania, the fence was charged with a field that caused any person entering it to suffer excruciating pain. During the struggle to win the right to communicate freely with the pequeninos, Ender's oldest stepson, Miro, was trapped in the field for several minutes, causing irreversible brain damage. Yet Miro's experience was only the most painful and immediate expression of what the fence did to the souls of the humans enclosed within it. The psychobarrier had been shut off thirty years ago. In all that time, there had been no reason to have any barrier between humans and pequeninos--yet the fence remained. The human colonists of Lusitania wanted it that way. They wanted the boundary between human and pequenino to remain unbreached.
That was why the xenobiology labs had been moved from their old location down by the river. If pequeninos were to take part in the research, the lab had to be close to the fence, and all the experimental fields outside it, so that humans and pequeninos wouldn't have occasion to confront each other unexpectedly.
When Miro left to meet Valentine, Ender had thought he would return to be astonished by the great changes in the world of Lusitania. He had thought that Miro would see humans and pequeninos living side by side, two species living in harmony. Instead, Miro would find the colony nearly unchanged. With rare exceptions, the human beings of Lusitania did not long for the close company of another species.
It was a good thing that Ender had helped the hive queen restore the race of buggers so far from Milagre. Ender had planned to help buggers and humans gradually come to know each other. Instead, he and Novinha and their family had been forced to keep the existence of the buggers on Lusitania a close-held secret. If the human colonists couldn't deal with the mammal-like pequeninos, it was certain that knowing about the insect-like buggers would provoke violent xenophobia almost at once.
I have too many secrets, thought Ender. For all these years I've been a speaker for the dead, uncovering secrets and helping people to live in the light of truth. Now I no longer tell anyone half of what I know, because if I told the whole truth there would be fear, hatred, brutality, murder, war.
Not far from the gate, but outside it, stood two fathertrees, the one named Rooter, the other named Human, planted so that from the gate it would seem that Rooter was on the left hand, Human on the right. Human was the pequenino whom Ender had been required to ritually kill with his own hands, in order to seal the treaty between humans and pequeninos. Then Human was reborn in cellulose and chlorophyll, finally a mature adult male, able to sire children.
At present Human still had enormous prestige, not only among the piggies of this tribe, but in many other tribes as well. Ender knew that he was alive; yet, seeing the tree, it was impossible for him to forget how Human had died.
Ender had no trouble dealing with Human as a person, for he had spoken with this fathertree many times. What he could not manage was to think of this tree as the same person he had known as the pequenino named Human. Ender might understand intellectually that it was will and memory that made up a person's identity, and that will and memory had passed intact from the pequenino into the fathertree. But intellectual understanding did not always bring visceral belief. Human was so alien now.
Yet still he was Human, and he was still Ender's friend; Ender touched the bark of the tree as he passed. Then, taking a few steps out of his way, Ender walked to the older fathertree named Rooter, and touched his bark also. He had never known Rooter as a pequenino--Rooter had been killed by other hands, and his tree was already tall and well-spread before Ender arrived on Lusitania. There was no sense of loss to trouble him when Ender talked to Rooter.
At Rooter's base, among the roots, lay many sticks. Some had been brought here; some were shed from Rooter's own branches. They were talking sticks. Pequeninos used them to beat a rhythm on the trunk of a fathertree; the fathertree would shape and reshape the hollow areas inside his own trunk to change the sound, to make a slow kind of speech. Ender could beat the rhythm--clumsily, but well enough to get words from the trees.
Today, though, Ender wanted no conversation. Let Planter tell the fathertrees that another experiment had failed. Ender would talk to Rooter and Human later. He would talk to the hive queen. He would talk to Jane. He would talk to everybody. And after all the talking, they would be no closer to solving any of the problems that darkened Lusitania's future. Because the solution to their problems n
ow did not depend on talk. It depended on knowledge and action--knowledge that only other people could learn, actions that only other people could perform. There was nothing that Ender could do himself to solve anything.
All he could do, all he had ever done since his final battle as a child warrior, was listen and talk. At other times, in other places, that had been enough. Not now. Many different kinds of destruction loomed over Lusitania, some of them set in motion by Ender himself, and yet not one of them could now be solved by any act or word or thought of Andrew Wiggin. Like all the other citizens of Lusitania, his future was in the hands of other people. The difference between him and them was that Ender knew all the danger, all the possible consequences of every failure or mistake. Who was more cursed, the one who died, unknowing until the very moment of his death, or the one who watched his destruction as it approached, step by step, for days and weeks and years?
Ender left the fathertrees and walked on down the well-beaten path toward the human colony. Through the gate, through the door of the xenobiology lab. The pequenino who served as Ela's most trusted assistant--named Deaf, though he was definitely not hard of hearing--led him at once to Novinha's office, where Ela, Novinha, Quara, and Grego were already waiting. Ender held up the pouch containing the fragment of potato plant.
Ela shook her head; Novinha sighed. But they didn't seem half as disappointed as Ender had expected. Clearly there was something else on their minds.
"I guess we expected that," said Novinha.
"We still had to try," said Ela.
"Why did we have to try?" demanded Grego. Novinha's youngest son--and therefore Ender's stepson--was in his mid-thirties now, a brilliant scientist in his own right; but he did seem to relish his role as devil's advocate in all the family's discussions, whether they dealt with xenobiology or the color to paint the walls. "All we're doing by introducing these new strains is teaching the descolada how to get around every strategy we have for killing it. If we don't wipe it out soon, it'll wipe us out. And once the descolada is gone, we can grow regular old potatoes without any of this nonsense."
