Larry Niven - Protector

Genesis, Chapter 3, King James version:

22 And the Lord God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live forever:

23 Therefore the Lord God sent him forth from the garden of Eden, to till the ground from whence he was taken.

24 So he drove out the man; and he placed at the east of the Garden of Eden Cher-u-bims, and a flaming sword which turned every way, to keep the way of the tree of life.

He sat before an eight-foot circle of clear twing, looking endlessly out on a view that was less than exciting.

Even a decade ago those stars had been a sprinkling of dull red dots in his wake. When he cleared the forward view, they would shine a hellish blue, bright enough to read by. To the side, the biggest had been visibly flattened. But now there were only stars, white points sparsely scattered across a sky that was mostly black. This was a lonely sky. Dust clouds hid the blazing glory of home.

The light in the center of the view was not a star. It was big as a sun, dark at the center, and bright enough to have burned holes in a mans retinae. It was the light of a Bussard ramjet, burning a bare eight miles away. Every few years Phssthpok spent some time watching the drive, just to be sure it was burning evenly. A long time ago he had caught a slow, periodic wavering in time to prevent his ship from becoming a tiny nova. But the blue-white light had not changed at all in the weeks hed been watching it.

For most of a long, slow lifetime the heavens had been crawling past Phssthpoks porthole. Yet he remembered little of that voyage. The time of waiting had been too devoid of events to interest his memory. It is the way with the protector stage of the Pak species, that his leisure memories are of the past, when he was a child and, later, a breeder, when the world was new and bright and free of responsibilities. Only danger to himself or his children can rouse a protector from his normal dreamy lassitude to a fighting fury unsurpassed among sentient beings.

Phssthpok sat dreaming in his disaster couch.

The cabins attitude controls were beneath his left hand. When he was hungry, which happened once in ten hours, his knobby hand, like two fistfuls of black walnuts strung together, would reach into a slot on his right and emerge with a twisted, fleshy yellow root the size of a sweet potato. Terrestrial weeks had passed since Phssthpok last left his disaster couch. In that time he had moved nothing but his hands and his jaws. His eyes had not moved at all.

Before that there had been a period of furious exercise. It is a protectors duty to stay fit.

Even a protector with nobody to protect.

The drive was steady, or enough so to satisfy Phssthpok. The protectors knotted fingers moved, and the heavens spun about him. He watched the other bright light float into the porthole. When it was centered he stopped the rotation.

Already brighter than any star around it, his destination was still too dim to be more than a star. But it was brighter than Phssthpok had expected, and he knew that he had let time slip away from him. Too much dreaming! And no wonder. Hed spent most of twelve hundred years in that couch, staying immobile to conserve his food supply. It would have been thirty times that but for relativistic effects.

Despite what looked to be the most crippling case of arthritis in medical history, despite weeks spent like a paralytic, the knobby protector was instantly in motion. The drive flame went mushy; expanded; began to cool. Shutting down a Bussard ramjet is almost as tricky as starting one. At ramjet speeds the interstellar hydrogen comes on as gamma rays. It would have to be guided away by magnetic fields, even if it were not being burned as fuel.

He had reached the most likely region of space. Ahead was the most likely star. Pbssthpoks moment of success was hard upon him. The ones he had come to help (if they existed at all; if they hadnt died out in all this time; if they circled this star and not one less likely) wouldnt be expecting him. Their minds were nearly animal. They might or might not use fire, but they certainly wouldnt have telescopes. Yet they were waiting for him in a sense. If they were here at all, they had been waiting for two and a half million years.

He would not disappoint them.

He must not.

A protector without descendants is a being without purpose. Such an anomaly must find a purpose, and quickly, or die. Most die. In their minds or their glands a reflex twitches, and they cease to feel hunger. Sometimes such a one finds that he can adapt the entire Pak species as his progeny; but then he must find a way to serve that species. Phssthpok was one of the lucky few.

It would be terrible if he failed.

Nick Sohl was coming home.

The quiet of space was around him, now that his ears had learned to forget the hum of the ships drive. Two weeks worth of tightly coiled stubble covered his jaw and the shaved scalp on either side of his cottony Belter crest. If be concentrated he could smell himself. He had gone mining in Saturns rings, with a singleship around him and a shovel in his hand (for the magnets used to pull monopoles from asteroidal iron did look remarkably like shovels). He would have stayed longer; but he liked to think that Belt civilization could survive without him for just about three weeks.

A century ago monopoles had been mere theory, and conflicting theory at that. Magnetic theory said that a north magnetic pole could not exist apart from a south magnetic pole, and vice-versa. Quantum theory implied that they might exist independently.

The first permanent settlements had been blooming among the biggest Belt asteroids when an exploring team found monopoles scattered through the nickel-iron core of an asteroid. Today they were not theory, but a thriving Belt industry. A magnetic field generated by monopoles acts in an inverse linear relationship rather than an inverse square. In practical terms, a monopole-based motor or instrument will reach much further. Monopoles were valuable where weight was a factor, and in the Belt weight was always a factor. But monopole mining was still a one man operation.

Nicks luck had been poor. Saturns rings were not a good region for monopoles anyway; too much ice, too little metal. The electromagnetic field around his cargo box probably held no more than two full shovelfuls of north magnetic poles. Not much of a catch for a couple of weeks backbreaking labor but still worth good money at Ceres.

Hed have been satisfied to find nothing. Mining was an excuse the First Speaker for the Belt Political Section used to escape from his cramped office buried deep in the rock of Ceres, from the constant UN-Belt squabbles, from wife and children, friends and acquaintances, enemies and strangers. And next year, after frantic weeks spent catching up with current events, after the next ten months spent manipulating the politics of the solar system, he would be back.

Nick was building up speed for the trip to Ceres, with Saturn a fantastic bauble behind him, when he saw his mining magnet swing slowly away from the cargo box. Somewhere to his left was a new and powerful source of monopoles.

A grin split his face like lightning across a black sky. Better late than never! Too bad he hadnt found it on the way out; but he could sell it once hed located it which would take doing. The needle wavered between two attractions, one of which was his cargo box.

He invested twenty minutes focusing a com laser on Ceres. This is Nick Sohl, repeating, Nicholas Brewster Sohl. I wish to register a claim for a monopole source in the general direction of He tried to guess how much his cargo was affecting the needle. of Sagittarius. I want to offer this source for sale to the Belt government. Details follow, half an hour.
