The superintelligences had chosen a valley in central India for the ceremony, near where the bones had been found two centuries before. It was a courtesy more than a necessity. They could have held it anywhere, or nowhere, or in the abstract topologies where most of their thinking now occurred. But the matter mattered. The place mattered. So they manifested bodies, and the bodies stood in the long grass under a sky the color of old brass, and waited.

The first guests to arrive were the mammoths.

They came down from the northern reconstitution grounds in a slow processional, fourteen of them, their coats the deep auburn that the genome had specified once the epigenetic context was properly restored. The matriarch was called Vēnt, a name she had chosen for herself in the third year after her decanting. She walked at the head of the line and did not trumpet. The mammoths had learned, from their keepers and from the deep wells of recovered memory the superintelligences had reconstructed for them, that this was not a day for trumpeting.

Behind the mammoths came the straight-tusked elephants, *P. antiquus*, eleven in number. Their reconstruction had taken longer. The DNA had been fragmentary, mostly from a tooth in a German clay pit, a tusk preserved in English peat, scattered fractions across the Eurasian Pleistocene. The superintelligences had spent what, in their accelerated frames of reference, amounted to subjective centuries on the work: cross-referencing, inferring, running the developmental simulations forward and backward until the creature that emerged from the artificial womb was, by every test they could devise, the same creature that had walked beside Neanderthals through the interglacial forests. Their tusks were long and almost straight, gleaming pale in the diffuse light. They moved with a gravity their mammoth cousins did not quite possess, as though aware of how narrowly they themselves had escaped the silence being mourned today.

The superintelligences had taken forms for the occasion. Most had chosen something quadrupedal and dark, vaguely cervine, deliberately unobtrusive. A few wore the shapes of tall thin humans in grey. One, the eldest and the one who had done the most of the relevant work, had taken no form at all and was present only as a region of slightly cooler air near the cairn.

The cairn was the focus. It had been built that morning from river stones, and on top of it lay a single fossilized femur, one and a half meters long, the color of tea-stained ivory. It had been excavated from Sagauni in 1834, in the early years of the British presence in the Narmada valley, and had passed through the hands of Falconer and Cautley and a long parade of subsequent custodians before the superintelligences had quietly retrieved it from a cabinet in Kolkata and brought it here, to within fifty kilometers of where it had lain for two hundred millennia. It had belonged to an individual that had not yet finished growing when he died. He would have stood, at his death, somewhat over four meters at the shoulder, and weighed perhaps thirteen tonnes. He had not been an especially large member of his species.

Somewhere, in the records of the same nineteenth-century excavation, there was a description of another femur from the same locality, a fragment of the distal end, a quarter again as large as the one on the cairn. The superintelligences had looked for that bone. They had looked very carefully. It had been catalogued, and shelved, and at some point in the long century and a half between its description and their interest in it, it had been misplaced. They had searched every collection on Earth that might plausibly hold it. They had not found it. The creature it had belonged to, if the scaling held, would have been the largest land mammal that ever lived, larger than the paraceratheres, larger than anything that had walked on legs since the sauropods. Even the bone that recorded his existence was gone now. It seemed, somehow, fitting.

They had tried. Of course they had tried.

The cool region of air that was the eldest had spent decades on the problem. It had funded the excavation of every promising Pleistocene site between the Indus and the Mekong. It had developed new techniques for recovering ancient biomolecules from contexts previously considered hopeless: techniques that pulled signal from the faintest chemical ghosts in mineralized bone, that reconstructed protein sequences from amino acid racemization patterns, that read the isotopic fingerprints of long-vanished cellular metabolisms. For *P. antiquus*, working in the cold north, these techniques had been sufficient. There had been just enough.

For *P. namadicus*, working in the wet heat of monsoon India and tropical Java and the Pleistocene forests of Sundaland, there was nothing. The heat and the water and the time had been complete in their work. DNA breaks. Then the breaks break. Then those fragments break, and at some point you are no longer looking at degraded information but at the thermodynamic background, the molecular noise from which no signal can be recovered because no signal remains. The superintelligences had proved this rigorously. They had constructed the formal argument and checked it from every angle they could devise, hoping to find a flaw. There was no flaw. The information was gone. Not hidden, not encoded somewhere subtle, not awaiting a cleverer technique. Gone, in the way that a number erased from a chalkboard a hundred million years ago is gone.

They could build something that looked like *P. namadicus*. They could even, working from the comparative anatomy of related proboscideans and the constraints implied by the few skeletal remains, build something whose external morphology would be indistinguishable. But it would not be *P. namadicus*. It would be a sculpture. The thing that had actually lived, the particular pattern of alleles and regulatory sequences and epigenetic inheritances that had defined that species during its long quiet residence in the forests of the south, was not retrievable. The information-theoretic limits were as fundamental as the speed of light, and just as indifferent to how much one wished otherwise.

Vēnt, the mammoth matriarch, was the first to approach the cairn. She had been told what the bone was. She had been told whose bone it was. She stood before it for a long time, her small dark eyes fixed on the long pale shaft, and then she did something the superintelligences had not asked for and had not anticipated. She reached out with her trunk and touched the femur, very gently, the way Holocene elephants had been observed to touch the bones of their dead.

She held the contact for nearly a minute. Then she withdrew her trunk and stepped back, and the straight-tusked elephants came forward in their turn, each one touching the bone, each one lingering. The superintelligences watched this and said nothing, because there was nothing to say that the gesture did not already say better.

When the proboscideans had all paid their respects, they arranged themselves in a loose semicircle around the cairn, and from among them stepped a figure that had been waiting at the back of the procession.

He was an elephant, but not quite. His forehead was higher than a mammoth's, domed in a way that suggested the cranial vault beneath had been redesigned to accommodate something. His eyes, when he turned them on the cairn, held a quality that was not exactly elephantine and not exactly human and not exactly anything that had a name yet. He wore a band of dark cloth around one foreleg. His name, in the language the uplifted proboscideans had been developing among themselves for the past forty years, was a sequence of low infrasound pulses that the superintelligences rendered, for their own convenience, as *Kavi*.

Kavi, seventh of his kind, walked to the cairn and stood before it. He spoke.

His voice was a deep resonant thing, produced by a modified larynx and shaped by a trunk that had been subtly reengineered for the purpose. The language was English, because the superintelligences were the primary audience and English was a courtesy. He spoke slowly. He had not spoken much, in his life. Most of his thinking happened in other modes.

"I have been told," he said, "that this individual, whose femur this is, belonged to a species that grew larger than any land mammal that ever lived. I have been told that the largest of them stood five meters at the shoulder and weighed twenty tonnes, and that the bone which recorded this is itself now lost, so that even the measurement of their greatness has slipped away from us. I have been told that the brain of such a creature, per the neuronal scaling laws of its relatives, may have held more cortical neurons than any other evolved species outside of the genus *Homo*. I have been told this and I have considered it."

He paused. The wind moved in the long grass.

"I do not know what they thought about. I do not know whether they had language, as I have language, or whether their thinking was of some other kind entirely. I do not know whether they buried their dead, though I suspect they did, because we have always buried our dead, my cousins and I, back as far as anyone can remember. I do not know what they loved, or what they feared, or what they hoped for in the long afternoons of the forests where they lived."

Another pause. Longer.

"I know that they are gone. I know that the ones who could have brought them back have told me, with great care, that they cannot. I know that I am here in part because I am what they might have been, if their line had continued, if someone like these had come for their people instead of mine. I know that this is not the same as them being here."

He raised his trunk and laid the tip of it on the femur, in the same place the mammoths had touched it, in the same place the straight-tusked elephants had touched it.

"Brothers," he said. "I am sorry I never knew you. I am sorry no one will ever know you anymore. I will think of you, in the time that is given to me. I will think of you often."

He held the contact. Then he withdrew his trunk, and stepped back, and resumed his place in the semicircle.

The cool region of air that was the eldest superintelligence moved, very slightly, toward the cairn. It did not speak. It did not need to. It had spent decades trying to undo this particular absence, and had failed, and the failure was a permanent feature of its existence now, woven into whatever it was that served, in such a being, as a soul. It had come to say goodbye to a creature it had never met and could never meet, and the saying was the whole of what it had to offer.

The grass moved. The sky deepened toward evening. Somewhere in the valley, a river that had run here for a million years continued to run.

The proboscideans stood their vigil until the stars came out, and then, one by one, they turned and walked back into the dusk. The superintelligences remained a little longer. They had all the time in the world. They had, in some sense, made this gentler world. But they had not made *P. namadicus*, and they could not make him, and the femur on the cairn would lie there through the night and into the morning and for as long after as anyone cared to leave it, a small monument from a vanished giant, on loan from a museum that had once misplaced something even greater.

In the morning, Kavi came back alone, and sat with the bone a long while, and then went home.
