The World That Couldn't Be

In Short

On the frontier planet Layard, human planter Gavin Duncan sets off into the wilderness to hunt down a Cytha, a feared local creature that is destroying his vital crop. Guided by a reluctant native tracker, Duncan pursues the beast across perilous terrain, surviving arrows, landslides, and violent localized storms. As the grueling hunt unfolds, the Cytha demonstrates bizarre powers of adaptation and survival. Ultimately, Duncan discovers that the creature is far more than a simple pest: it is the central reproductive womb for all animal life on the planet, forcing him to rethink his relationship with the alien ecosystem.

The Story

Gavin Duncan is a pragmatic Earthman determined to build a life as a planter on the planet Layard. When a mysterious native creature known as the Cytha harvests and destroys several rows of his prized vua crop, Duncan refuses to let his livelihood be wiped out. Disregarding the deep superstitious dread of his native foreman and the mild academic curiosity of Shotwell, a resident sociologist, Duncan grabs his rifle and emergency rations to track the beast into the dangerous bush. He takes along Sipar, a native tracker who is petrified of the legendary Cytha yet bound by a strange personal code to follow Duncan to the end.

The chase proves far more arduous than Duncan anticipated. Early in the hunt, he shoots the Cytha dead-center, only to discover that the blast merely blows off a few pounds of flesh while the rest of the creature vanishes. As they push further into unexplored territory beyond a massive escarpment, the landscape becomes increasingly hostile. They survive a mystery archer's arrow, a sudden violent windstorm called a skun, and a roaring midnight rockslide that buries their campfire and destroys their canteens. Through every trial, Sipar remains strangely loyal, even as he hints at an inevitable death.

After crossing a wide river into an uncharted forest, the hunt takes a surreal turn. Sipar commits suicide by cutting his own throat, an act driven by an underlying loyalty not to Duncan, but to the Cytha itself. Left alone in the dark forest, Duncan is shocked when the Cytha begins speaking to him from the brush. The creature offers a peaceful parley, but Duncan opens fire, blowing off more lumps of flesh.

When morning comes, Duncan falls into a trap and ends up pinned beneath a fallen tree right after a skun strikes. Nearby, the Cytha collapses into a pit, disintegrating into a throbbing, glowing skeleton surrounded by miniature versions of every animal species on Layard—including baby screamers, donovans, and native humanoids. Duncan realizes the Cytha is a sexless "crisis-beast" and the living nursery-mother for the entire planetary ecosystem.

Using his rifle as a reach tool, Duncan helps the tiny creatures and the Cytha climb out of the pit. Reassembled but diminished, the Cytha initially trots off, but returns with a massive donovan that butts the fallen tree off Duncan's trapped leg. Realizing they are even, Duncan and the Cytha strike a verbal bargain: the creature will avoid the vua fields, and Duncan will cease hunting it. Hobbling back to his farm on a rifle-crutch, Duncan is escorted to the edge of the forest by the Cytha, which feels its temporary intelligence slipping back into comfortable ignorance, already happily planning to hatch a dozen humanoids just like Duncan in its next brood.

How It Unfolds

The raid on the crop Gavin Duncan discovers ten rows of his essential vua plants sheared off by a nocturnal raider on his frontier farm. Despite warnings from his native foreman, Zikkara, that no one hunts the legendary Cytha, Duncan grabs his heavy rifle and sets off with a native tracker named Sipar.

The vanishing beast Following tracks through the brutal heat of the bush, Duncan spots the luminescent, lion-sized black beast on a knoll and lands a direct shot with his rifle. When he reaches the spot, he finds only three gouts of torn flesh on the ground while the Cytha itself has mysteriously vanished into thin air.

Peril on the trail The hunt drags across the wilderness where Duncan and Sipar barely dodge an arrow fired from the brush and witness the destructive path of a skun windstorm. A catastrophic rockslide at the base of a high escarpment destroys their camp and water supply, yet Sipar vows to stay with Duncan to the death.

A night of revelations After swimming across a broad river into an untouched forest, Sipar unexpectedly cuts his own throat out of latent devotion to the beast. Alone by the campfire, Duncan is startled when the Cytha speaks directly to him from the dark, offering a truce before Duncan shoots it apart once more.

The mother of the world Trapped beneath a fallen tree after a storm, Duncan watches the Cytha fall into a pit and break down into its base form: a glowing skeleton surrounded by tiny offspring of every animal species on Layard. Duncan saves the brood using his rifle, prompting the reassembled Cytha to bring a massive donovan to lift the log off his leg.

A bargain struck Recognizing the Cytha's vital role as the planetary mother, Duncan strikes an agreement with the beast to protect his crops without further bloodshed. As Duncan hobbles home on his rifle-crutch, the Cytha sheds its temporary intelligence, gleefully deciding to incorporate human attributes into its next batch of young.

The People

• Gavin Duncan wants to protect his agricultural investment on Layard at all costs, viewing the planet's wildlife and native laborers through a hard-nosed, utilitarian lens. Driven by stubborn determination and a hunter's pride, his relentless pursuit of the Cytha exposes him to life-threatening danger, but his survival instincts and willingness to adapt eventually lead him to respect the alien ecosystem rather than try to conquer it.

• Sipar is a lithe native tracker who wants to fulfill his duty as a guide despite his deep-seated terror of the Cytha. Though he fears the creature and acknowledges his taboos regarding certain local beasts, his true spiritual loyalty lies with the Cytha as the source of all life, ultimately driving him to sacrifice himself on the trail.

• The Cytha is a unique biological entity that wants to protect its brood and maintain harmony within its territory while adapting its intelligence to match external threats. When hunted, it evolves reasoning and speech to parley with Duncan, eventually demonstrating gratitude by freeing him from under a tree and making a lasting peace bargain.

• Shotwell is an Earth sociologist stationed at Duncan's farm who wants to study the native humanoid population. He remains in the background as an inquisitive academic, representing the theoretical curiosity that contrasts with Duncan's practical, hands-on frontier life.

In Its Own Voice

"Before I came, you'd feast one day, then starve for days on end; but now you eat each day. And you like the doctoring. Before, when you got sick, you died."

Duncan confronts his foreman, laying out the practical, paternalistic bargain he believes he has struck with the native population.

"Something from one planet and something from another and still something further from a third and so was built up through the wide social confederacy of space a truly cosmic culture which in the end, in another ten thousand years or so, might spell out some way of life with more sanity and understanding than was evident today."

As he rests by the fire, Duncan reflects on the blending of Earth crops and alien worlds within a broader galactic civilization.

"If you find me in the vua, just begin hunting me. With you after me, I will quickly get smart and remember once again and it will be all right."

The Cytha offers a delightfully pragmatic solution for maintaining their bargain after its temporary intelligence fades back into animal instinct.

What It's Really About

Beneath its adventure-packed narrative of a frontier hunt, the story examines the friction between human agricultural colonialism and complex alien ecosystems. Gavin Duncan initially views the environment through the lens of ownership, resource control, and pest extermination. However, the narrative dismantles this human-centric arrogance by revealing that the planet operates on a unified, sexless biological structure where a single creature serves as the maternal origin for all species. It questions the assumption that intelligence is the ultimate evolutionary goal, proposing instead that adaptive, temporary smartness—lapsing back into contented ignorance when crisis passes—might be a far more peaceful way to exist. Ultimately, it argues that true harmony requires empathy and compromise rather than domination.
