Picnic On Nearside

"No."

"That is a true statement. Now for the other mistake. We are not self-righteous bastards. We're pragmatists. And we're not religious fanatics, not really, though we all come to believe deeply in what we're doing out here. And that brings us to the third mistake. The primary reasons we're out here have little to do with defeating the Engineers. We're all out here for our own personal reasons, too."

"And what are they?"

"They're personal. Each of us had a different reason for coming. You are out here to satisfy the last dregs of a jaded appetite; that's a common reason. You have some surprises coming up, but you'll stay. You'll have to. You won't be able to bear leaving. And you'll like it. You might even help us fight the Engineers."

She looked at him with suspicion.

"We don't care why you're out here. Your story doesn't impress me one way or the other. You probably expected condemnation or contempt. Don't flatter yourself. As long as you're not here to help paint Ring Beta red, we don't care."

"Then when do I get a Symb?"

"As soon as you can undergo a bit of surgery." For the first time he unbent a little. The corners of the slit that covered his mouth bent up in a silly attempt at a smile. "I must confess that I was interested by one thing you said. How do you have sex with an elephant?"

Parameter kept a perfectly straight face.

"You don't have sex with an elephant. The best you can do is have sex at an elephant."

The Symb was a soft-looking greenish lump in the center of the room. With the best will in the world, Parameter could not see that it resembled anything so much as a pile of green cow manure. It was smaller than she had expected, but that was because it had no occupant. She was about to remedy that.

She stumped over to it and looked down dubiously. She had no choice but to walk awkwardly; her legs were no longer built for walking. They had been surgically altered so that the best she could do was a grotesque bowlegged prancing, stepping high so her long fingers would clear the floor. She was now ideally suited for a weightless existence. In a gravitational field, she was clumsy beyond belief.

The man who had interviewed her, whom she now knew by the name of Bushwacker, was the only other occupant of the room. He handled himself better than she did, but only slightly. He was itching to get back to the Rings; this base duty galled him. Gravity was for poor flatfoots.

"Just touch it, that's all?" she said. Now that it had come to it, she was having second thoughts.

"That's right. The Symb will do the rest. It won't be easy. You'll have between six weeks and three months of sensory deprivation while the personality develops. You'd go crazy in two days, but you won't be alone. All you'll have to hang on to will be the mind of the Symb. And it'll be a baby, hard to get along with. You'll grow up together."

She took a deep breath, wondering why she was so reluctant. She had done things easily that were much more repulsive than this. Perhaps it was the dawning realization that this would be much more than a simple lark. It could last a long time.

"Here goes." She lifted her leg and touched one of her ped-fingers to the blob. It stuck. The Symb slowly began stirring.

The Symb was... warm? No, at first she thought so, but it would be more accurate to say it was no temperature at all. It was thirty-seven degrees: blood temperature. It oozed up her leg, spreading itself thi

"Inhale," Bushwacker advised. "It'll help a little."

She did so, just as the Symb moved over her chin. It moved over her mouth and nose, then her eyes.

There was a moment of near-panic when part of her brain told her she must take a breath, and she dutifully tried to. Nothing happened, and she wanted to scream. But it was all right. She didn't need to breathe. When she opened her mouth the Symb flowed down her throat and trachea. Soon her lungs were filled with the interface tissue whose function it was to put oxygen in her blood and remove carbon dioxide. It filled her nasal passages, slithered up the eustachian tube to her i

It was a shock, even though she had expected it, when the Symb entered her anus and vagina. Not a bad shock. Rather a thrill, actually. It filled the spaces in her uterus, wound into the urethra to fill the bladder, then up the ureter to mingle with the kidneys. Meanwhile another tendril had filled the large and small intestine, consuming the nutrients it found there, and joined with the tendril coming from her mouth. When it was done, she was threaded like the eye of a serpentine needle, and was revealed to any that could see as a topological example of a torus.

The silence closed in. It was absolutely quiet for a period of time she was powerless to measure, but couldn't have been longer than five minutes.

The obvious place where the human brain is accessible without violating any solid membranes is alongside the eyeball and through the supraorbital foramen. But the Symb would not be able to get a very substantial tendril through in the tight confines of the eye. So the genetic engineers, elaborating on the basic design for oxygen breathers received over the Ophiuchi Hotline, had given the Symb the capability of forcing an entry through the top of the skull.

Parameter felt a twinge of pain as a two-centimeter hole was eaten in the top of her head. But it subsided as the Symb began to feel out the proper places to make co

Suddenly she was surrounded by fear; childish, inconsolable fear that frightened her out of her wits but did not come from her mind. She fought it, but it only became more insistent. In the end, she abandoned herself to it and cried like a baby. She became an infant, sloughing off her seventy-odd years there in the impalpable darkness like they had never happened.

There was nothing; nothing but two very lost voices, crying in the void.

There had been a debate raging for centuries as to whether the Symbiotic Space-Environment Organisms were really a form of artificial intelligence. (Or alien intelligence, depending on your definition.) The people who lived in them were unanimously of the opinion that they were. But the other side—who were mostly psychologists—pointed out that the people who actually lived in them were in the worst possible place to judge. Whatever one's opinion on the subject, it was based on personal prejudice, because there could be no objective facts.

The Symbs were genetically tailored organisms that could provide a complete, self-contained environment for a single human being in space. They thrived on human waste products: urine, feces, heat, and carbon dioxide.

They contained several chlorophyll-like enzymes and could accomplish photosynthesis utilizing the human's body heat, though at a low efficiency. For the rest of the energy needs of the pair, the Symb could use sunlight. They were very good at storing energy in chemical compounds that could be broken down later at need. Together with a human, a Symb made a self-contained heat engine. They were a closed ecology, neither host nor parasite: a symbiosis.

To the human being, the Symb was a green pasture, a ru
