Diaspora

Orlando wasn't fooled or confused for a moment—it was an auditory hallucination, a product of stress—but he grabbed the words like a lifeline. Liana would have goaded him out of self-pity; that much of her survived in his head.

He forced himself to concentrate. Somehow, the singularity had slipped—which meant the Transmuters' long-neutron anchor, binding the home universe to macrosphere time, was losing its grip. Yatima, Blanca, and all the other dazzlingly brilliant experts in extended Kozuch Theory had failed to predict anything of the kind—which meant no one would know if, or when, or by how many centuries it might slip again.

But once or twice more could easily be enough to carry them right past the core burst.

The news might jolt the others into cloning the polis and searching for the Transmuters elsewhere. But even without another singularity slip they'd barely have time to visit two or three more stars. And while every instinct he possessed told him that the Hermits were dumb animals, every instinct he possessed was too far from the world that had shaped it to know gauche from droit.

Playing Hermit would never be enough to reach them. Riding a robot, reshaping his body image, crawling around on the hypersurface would never be enough. It was no use pretending that a single mind could embrace Earth and Poincare, U and U-star, three dimensions and five. Escape and crash. No one could bend that much; he had to break.

Orlando told his exoself, "Build a copy of the cabin. Here." He gestured at one wall and it turned to glass; behind it, like an uninverted mirror image, the room was repeated in every detail. "Thicken it into a 5-scape."

Nothing seemed to change, but he was seeing only the three-dimensional shadow.

He steeled himself. "Now clone me in there, in my 5-body, with all macrospherean visual symbols."

Suddenly he was inside the 5-scape. He laughed, hugging himself with all four arms, trying not to hyperventilate. "No Alice jokes, Liana, please." He had to concentrate to find the two-dimensional slice of the tesseract wall that revealed the adjoining three-dimensional cabin; it was like staring at a tiny peep-hole. His paper-doll original, the unchanged Orlando, pressed a hand against the glass in a vaguely reassuring gesture, trying not to appear too relieved. And in truth, in spite of the panic he felt, he was relieved himself not to be confined in that claustrophobic sliver of a world any more.

He caught his breath. "Now adjoin the robot's scape." The opposite wall became transparent, and behind it he could see the hypersurface of Poincare; the robot was still standing a few delta from the entrance to the real Hermit's cave.

"Remove the robot. Clone me in there, with the Hermit body-image and senses, and Elena's gestural language. And—" He hesitated. This was it, the spiral down. "Tear out every symbol relating to my old body, my old senses."

Ve was on the hypersurface. Through a floating four-dimensional window, he could see—with the xenologists' best-guess Hermitian vision—the 5-cabin and its occupant, all the colors translated into false heat tones. The whole scene was obviously physically impossible: surreal, absurd. The 3-scape of the original cabin was too small and too far away to see at all. Ve looked around at the gently glowing landscape; everything appeared more natural now, more intelligible, more harmonious.

Elena had invented a gestural language for the Hermits' batons; there was no pretense of capturing real Hermitian, but the artificial version did allow citizens to think in gestural impulses and images instead of their native tongue, and to communicate with their exoselves without violating the simulation of Hermit anatomy.

Ve extruded all twelve batons, and instructed vis exoself to duplicate the scape, then clone ver yet again with further modifications. Some came from the xenologists' observations of other species' behavior, some came from Blanca's old notes on possible macrospherean mental structures, and some came from vis own immediate sense of the symbols ve required in order to fit this body and this world more closely.

The third altered clone of Orlando peered back down the tu

After a while, ve turned away from the window. The Hermit's cave itself was still beyond reach, but it was easier now to go forward than back.

Orlando paced the cabin, ignoring messages from Paolo and Yatima. The seventh clone had taken control of the robot nine kilotau ago, and almost immediately managed to persuade the real Hermit to leave its cave. They'd been miming and gesticulating at each other ever since.

When the robot finally left the Hermit to converse with the sixth clone, Orlando could see all the others watching intently; even the first clone seemed riveted, as if he was extracting some aesthetic pleasure from the five-dimensional baton-waving despite being blind to its meaning.

Orlando waited, his guts knotted, as the message passed up the chain toward him. What would happen to these messengers—more like children than clones—once they'd served their purpose? Bridgers had never been isolated; everyone had been linked to a large, overlapping subset of the whole community. What he'd done was an insane perversion of that ethos.

"There's good news and had news." His four-legged clone was standing behind the wall, face changing shape slightly as his head moved in unseen dimensions. Orlando stepped up to the glass.

"They're intelligent? The Hermits—"

"Yes. Elena was right. They tweaked the ecosystem. More than we guessed. They're not just immune to climate change and population swings; they're immune to mutation, new species arising, anything short of Poincare going supernova. Everything's still free to evolve around them, but they sit at a fixed point in the system while it changes."

Orlando was staggered; that kind of long-term dynamic equilibrium was far beyond anything the exuberants of Earth had ever contemplated. It was at least as impressive as tying neutrons in knots. "They're not… the Transmuters? Reduced to this?"

His clone's shadow-face shimmered with mirth.

"No! They're native to Poincare, they've never left, they've never traveled. But don't 'took so disgusted.. They've had their age of barbarism, and they've had disasters to rival Lacerta. This is their sanctuary, now. Their invulnerable Atlanta. How can we begrudge them that?

Orlando had no reply.

The clone said, "But they do remember the Transmuters. And they know where they've gone."

"Where?" Even the closest star might take too long to reach, if the singularity slipped again. "Are they in the desert? In a polis?"

"No."

"Which star, then?" Maybe there was still hope, if they used all their fuel for a fast one-way voyage, and relied on signaling back to the station rather than returning physically.

"No star—or none that the Hermits could point to. They're not in the macrosphere at all."

"You mean… they found a way to enter another four-dimensional universe? To break in?" Orlando hardly dared believe it; if it was true, they could bring everyone through to the macrosphere, wait for the radiation to pass, then borrow the Transmuters' trick to get back to the home universe itself—whether or not any robots survived on Kafka or Swift.

The clone smiled wistfully. "Not quite. But the good news is, the second macrosphere is four-dimensional."
