Symbiont
by Robert Silverberg
Ten years later, when I was long out of the Service and working the turnaround wheel at Betelgeuse Station, Fazio still haunted me. Not that he was dead. Other people get haunted by dead men; I was haunted by a live one. It would have been a lot better for both of us if he had been dead, but as far as I knew Fazio was still alive.
He’d been haunting me a long while. Three or four times a year his little dry thin voice would come out of nowhere and I’d hear him telling me again, “Before we go into that jungle, we got to come to an understanding. If a synsym nails me, Chollie, you kill me right away, hear? None of this shit of calling in the paramedics to clean me out. You just kill me right away. And I’ll do the same for you. Is that a deal?”
This was on a planet called Weinstein in the Servadac system, late in the Second Ovoid War. We were twenty years old and we were volunteers: two dumb kids playing hero. “You bet your ass,” is what I told him, not hesitating a second. “Deal. Absolutely.” Then I gave him a big grin and a handclasp and we headed off together on spore-spreading duty.
At the time, I really thought I meant it. Sometimes I still believe that I did.
Ten years. I could still see the two of us back there on Weinstein, going out to distribute latchenango spores in the enemy-held zone. The planet had been grabbed by the Ovoids early in the war, but we were starting to drive them back from that whole system. Fazio and I were the entire patroclass="underline" you get spread pretty thin in galactic warfare. But there was plenty of support force behind us in the hills.
Weinstein was strategically important, God only knows why. Two small continents—both tropical, mostly thick jungle, air like green soup—surrounded by an enormous turbulent ocean: never colonized by Earth, and of no use that anyone had ever successfully explained to me. But the place had once been ours and they had taken it away, and we wanted it back.
The way you got a planet back was to catch a dozen or so Ovoids, fill them full of latchenango spores, and let them return to their base. There is no life-form a latchenango likes better as its host than an Ovoid. The Ovoids, being Ovoids, would usually conceal what had happened to them from their pals, who would kill them instantly if they knew they were carrying deadly parasites. Of course, the carriers were going to die anyway—latchenango infestation is invariably fatal to Ovoids—but by the time they did, in about six standard weeks, the latchenangos had gone through three or four reproductive cycles and the whole army would be infested. All we needed to do was wait until all the Ovoids were dead and then come in, clean the place up, and raise the flag again. The latchenangos were generally dead too by then, since they rarely could find other suitable hosts. But even if they weren’t, we didn’t worry about it. Latchenangos don’t cause any serious problems for humans. About the worst of it is that you usually inhale some spores while you’re handling them, and it irritates your lungs for a couple of weeks so you do some pretty ugly coughing until you’re desporified.
In return for our latchenangos the Ovoids gave us synsyms.
Synsyms were the first things you heard about when you arrived in the war zone, and what you heard was horrendous. You didn’t know how much of it was myth and how much was mere bullshit and how much was truth, but even if you discounted seventy-five percent of it the rest was scary enough. “If you get hit by one,” the old hands advised us, “kill yourself fast, while you have the chance.” Roving synsym vectors cruised the perimeter of every Ovoid camp, sniffing for humans. They were not parasites but synthetic symbionts: when they got into you, they stayed there, sharing your body with you indefinitely.
In school they teach you that symbiosis is a mutually beneficial state. Maybe so. But the word that passed through the ranks in the war zone was that it definitely did not improve the quality of your life to take a synsym into your body. And though the Service medics would spare no effort to see that you survived a synsym attack—they aren’t allowed to perform mercy killings, and wouldn’t anyway—everything we heard indicated that you didn’t really want to survive one.
The day Fazio and I entered the jungle was like all the others on Weinstein: dank, humid, rainy. We strapped on our spore-tanks and started out, using hand-held heat-piles to burn our way through the curtains of tangled vines. The wet spongy soil had a purplish tinge and the lakes were iridescent green from lightning-algae.
“Here’s where we’ll put the hotel landing strip,” Fazio said lightly. “Over here, the pool and cabanas. The gravity-tennis courts here, and on the far side of that—”
“Watch it,” I said, and skewered a low-flying wingfinger with a beam of hot purple light. It fell in ashes at our feet. Another one came by, the mate, traveling at eye-level with its razor-sharp beak aimed at my throat, but Fazio took it out just as neatly. We thanked each other. Wingfingers are elegant things, all trajectory and hardly any body mass, with scaly silvery skins that shine like the finest grade of moonlight, and it is their habit to go straight for the jugular in the most literal sense. We killed twelve that day and I hope it is my quota for this lifetime. As we advanced into the heart of the jungle we dealt just as efficiently with assorted hostile coilworms, eyeflies, dingleberries, leper bats, and other disagreeable local specialties. We were a great team: quick, smart, good at protecting each other.
We were admiring a giant carnivorous fungus a klick and a half deep in the woods when we came upon our first Ovoid. The fungus was a fleshy phallic red tower three meters high with orange gills, equipped with a dozen dangling whiplike arms that had green adhesive knobs at the tips. At the ends of most of the arms hung small forest creatures in various stages of digestion. As we watched, an unoccupied arm rose and shot forth, extended itself to three times its resting length, and by some neat homing tropism slapped its adhesive knob against a passing many-legger about the size of a cat. The beast had no chance to struggle; a network of wiry structures sprouted at once from the killer arm and slipped into the victim’s flesh, and that was that. We almost applauded.
“Let’s plant three of them in the hotel garden,” I said, “and post a schedule of feeding times. It’ll be a great show for the guests.”
“Shh,” Fazio said. He pointed.
Maybe fifty meters away a solitary Ovoid was gliding serenely along a forest path, obviously unaware of us. I caught my breath. Everyone knows what Ovoids look like, but this was the first time I had seen a live one. I was surprised at how beautiful it was, a tapering cone of firm jelly, pale blue streaked with red and gold. Triple rows of short-stalked eyes along its sides like brass buttons. Clusters of delicate tendrils sprouting like epaulets around the eating-orifice at the top of its head. Turquoise ribbons of neural conduit winding round and round its equator, surrounding the dark heart-shaped brain faintly visible within the cloudy depths. The enemy. I was conditioned to hate it, and I did; yet I couldn’t deny its strange beauty.
Fazio smiled and took aim and put a numb-needle through the Ovoid’s middle. It froze instantly in mid-glide; its color deepened to a dusky flush; the tiny mouth-tendrils fluttered wildly but there was no other motion. We jogged up to it and I slipped the tip of my spore-distributor about five centimeters into its meaty middle. “Let him have it!” Fazio yelled. I pumped a couple of c.c.’s of latchenango spores into the paralyzed alien. Its soft quivering flesh turned blue-black with fear and rage and God knows what other emotions that were strictly Ovoid. We nodded to each other and moved along. Already the latchenangos were spawning within their host; in half an hour the Ovoid, able once more to move, would limp off toward its camp to start infecting its comrades. It is a funny way to wage war.
