“So visitors to Zoo can wander comfortably around with gravity polarizer platforms between the cages,” he said aloud, angrily because he could see the towering masses of conifers in the next compound. It was an Earth compound, all right—but he could see no evidence of animals across that distance, and that made him fiercely glad for some reason. He ached to cross those impenetrable barriers, and his vision of lofty conifers blurred with his tears.
His feet were freezing, now, and no vegetation grew as near as the frost that lined the ice rim. “You’re good, but you’re not perfect,” he said to the builders. “You can’t keep the heat in these compounds from leaking away at the rims.” Hence frozen moisture and the lack of vegetation along the rim, and higher rainfall where clouds skirted that cold force wall.
Scanning the vast panoramic arc of that ice rim, Locklear noted that his prison compound had a gentle bowl shape, though some hills and crags surged up in the lowlands. Maybe using the natural contours of old craters? Or maybe you made those craters. It was an engineering project that held tremendous secrets for humankind, and it had been there for one hell of a long time. Widely spaced across that enormous bowl were spots of dramatic color, perhaps flowers. But they won’t scatter much without animal vectors to help the wind disperse seeds and such. Dammit, this place wasn’t finished!
He retraced his steps downward. There was no point in making a camp in this inclement place, and with every sudden whistle of breeze now he was starting to look up, scanning for the kzin ship he knew might come at any time. He needed to find a cave, or to make one, and that would require construction tools.
Late in the afternoon, while tying grass bundles at the edge of a low rolling plain, Locklear found wood of the kind he’d hardly dared to hope for. He simply had not expected it to grow horizontally. With a thin bark that simulated its surroundings, it lay mostly below the surface with shallow roots at intervals like bamboo. Kzinti probably would’ve known to seek it from the first, damn their hairy hides. The stuff—he dubbed it shamboo—grew parallel to the ground and arrow-straight, and its foliage popped up at regular intervals too. Some of its hard, hollow segments stored water, and some specimens grew thick as his thighs and ten meters long, tapering to wicked growth spines on each end. Locklear had been walking over potential hiking staffs, construction shoring, and rafts for a week without noticing. He pulled up one the size of a javelin and clipped it smooth.
His grooming tool would do precision work, but Locklear abraded blisters on his palms fashioning an axehead from a chertlike stone common in seams where basalt crags soared from the prairie. He spent two days learning how to socket a handaxe in a shamboo handle, living mostly on tuberberries and grain from grassheads, and elevated his respect for the first tool-using creatures in the process.
By now, Locklear’s right arm felt almost as good as new, and the process of rediscovering primitive technology became a compelling pastime. He was so intent on ways to weave split shamboo filaments into cordage for a firebow, while trudging just below the basalt heights, that he almost missed the most important moment of his life.
He stepped from savannah grass onto a gritty surface that looked like other dry washes, continued for three paces, stepped up onto grassy turf again, then stopped. He recalled walking across sand-sprinkled tiles as a youth, and something in that old memory made him look back. The dry wash held wavelike patterns of grit, pebbles, and sand, but here and there were bare patches.
And those bare patches were as black and as smooth as machine-polished obsidian.
Locklear crammed the half-braided cord into a pocket and began to follow that dry wash up a gentle slope, toward the cleft ahead, and toward his destiny.

His heart pounding with hope and fear, Locklear stood five meters inside the perfect arc of obsidian that formed the entrance to that cave. No runoff had ever spilled grit across the smooth broad floor inside, and he felt an irrational concern that his footsteps were defiling something perfectly pristine, clean and cold as an ice cavern. But a far, far more rational concern was the portal before him, its facing made of the same material as the floor, the opening itself four meters wide and just as high. A faint flickering luminescence, as of gossamer film stretched across the portal, gave barely enough light to see. Locklear saw his reflection in it, and wanted to laugh aloud at this ragged, skinny, barrel-chested apparition with the stubble of beard wearing stained flight togs. And the apparition reminded him that he might not be alone.
He felt silly, but after clearing his throat twice he managed to call out: “Anybody home?”
Echoes; several of them, more than this little entrance space could possibly generate. He poked his sturdy shamboo hiking staff into the gossamer film and jumped when stronger light flickered in the distance. “Maybe you just eat animal tissue,” he said, with a wavering chuckle. “Well—” He took his grooming pincers and cut away the dried curl of skin around a broken blister on his palm, clipped away sizeable crescents of fingernails, tossed them at the film.
Nothing but the tiny clicks of cuticles on obsidian, inside; that’s how quiet it was. He held the pointed end of the staff like a lance in his right hand, extended the handaxe ahead in his left. He was right-handed, after all, so he’d rather lose the left one . . .
No sensation on his flesh, but a sudden flood of light as he moved through the portal, and Locklear dashed backward to the mouth of the cave. “Take it easy, fool,” he chided himself. “What did you see?”
A long smooth passageway; walls without signs or features; light seeming to leap from obsidian walls, not too strong but damned disconcerting. He took several deep breaths and went in again, standing his ground this time when light flooded the artificial cave. His first thought, seeing the passageway’s apparent end in another film-spanned portal two hundred meters distant, was, Does it go all the way from Kzersatz to Newduvai? He couldn’t recall when he’d begun to think of this kzin compound as Kzersatz and the adjoining, Earthlike, compound as Newduvai.
Footfalls echoing down side corridors, Locklear hurried to the opposite portal, but frost glistened on its facing and his staff would not penetrate more than a half-meter through the luminous film. He could see his exhalations fogging the film. The resistance beyond it felt spongy but increasingly hard, probably an extension of that damned force wall. If his sense of direction was right, he should be just about beneath the rim of Kzersatz. No doubt someone or something knew how to penetrate that wall, because the portal was there. But Locklear knew enough about force walls and screens to despair of getting through it without better understanding. Besides, if he did get through he might punch a hole into vacuum. If his suspicions about the builders of Zoo were correct, that’s exactly what lay beyond the portal.
Sighing, he turned back, counting nine secondary passages that yawned darkly on each side, choosing the first one to his right. Light flooded it instantly. Locklear gasped.
Row upon row of cubical, transparent containers stretched down the corridor for fifty meters, some of them tiny, some the size of a small room. And in each container floated a specimen of animal life, rotating slowly, evidently above its own gravity polarizer field. Locklear had seen a few of the creatures; had seen pictures of a few more; all, every last one that he could identify, native to the kzin homeworld. He knew that many museums maintained ranks of pickled specimens, and told himself he should not feel such a surge of anger about this one. Well, you’re an ethologist, you twit, he told himself silently. You’re just pissed off because you can’t study behaviors of dead animals. Yet, even taking that into consideration, he felt a kind of righteous wrath toward builders who played at godhood without playing it perfectly. It was a responsibility he would never have chosen. He did not yet realize that he was surrounded with similar choices.
He stood before a floating vatach, in life a fast-moving burrower the size of an earless hare, reputedly tasty but too mild-mannered for kzinti sport. No symbols on any container, but obvious differences among the score of vatach in those containers.
How many sexes? He couldn’t recall. “But I bet you guys would,” he said aloud. He passed on, shuddering at the critters with fangs and leathery wings, marveling at the stump-legged creatures the height of a horse and the mass of a rhino, all in positions that were probably fetal though some were obviously adult.
