Xenocide

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 pla

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 now 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.”
