George R. R. Martin's 'Thousand Worlds' Universe Wiki

Tuf Voyaging is a science-fiction fix-up novel by George R. R. Martin, first published in 1986 by Baen Books. It takes place in the "Thousand Worlds" universe, and is set across several planets in the Jambles, Fyndii Space and the Manrealm. Events take place during the post-Interregnum period, around the year ai-1000. The chapters of Tuf Voyaging were originally published as short stories over several years, before they were collected and revised into a single novel.

The novel concerns the (mis)adventures of Haviland Tuf, a solitary space trader who inadvertently becomes the master of the Ark, an ancient and powerful warship with advanced ecological engineering capabilities. Tuf travels the galaxy, offering his services to worlds with environmental problems, and sometimes imposing solutions of his own.[1]

Plot Summary


"The Plague Star"

The story begins with four people requiring interstellar transport: Celise Waan, a scholar of anthropology; Jefri Lion, a scholar and retired soldier; Anittas, a cybertech; and Kaj Nevis, the leader of the expedition. They hire Rica Dawnstar, a mercenary bodyguard, and acquire the services of Haviland Tuf, a not-very-successful trader.

Their destination is a so-called "plague star," known to inflict disease and pestilence on every third generation of a small, remote world. It turns out to be an enormous, abandoned seedship of the long-defunct Federal Empire's Ecological Engineering Corps, developed by the Corps to rewrite genetic coding for entire planets, for good or for ill. Tuf's ship, the Cornucopia of Excellent Goods at Low Prices, is damaged by the seedship's automated defenses, and three of the occupants, Nevis, Anittas, and Dawnstar, board the seedship by means of pressure suits, leaving the others to await eventual death through asphyxiation. However, Tuf locates a microchip allowing him, Waan, and Lion to land the Cornucopia safely on the seedship.

Nevis, who has stolen a bulky but extremely powerful alien exoskeleton from Tuf's ship, forces Anittas, a cyborg, to invade the ship's circuits. In the process, Anittas's suit is torn, and he contracts a plague from the air. Alarmed by this brutality and worried Nevis will use his suit's power to subjugate her as well, Dawnstar runs away from Nevis, ultimately finding the vast seedship's control room. Anittas, meanwhile, betrays Nevis, releasing several of the ship's macroscopic bioweapons, including acid-spitting "hellkittens"; hyper-aggressive, carnivorous, bat-like creatures; spider-like, unimaginably sharp-edged organisms known as "walking webs"; and a tyrannosaurus rex. Furious at his treachery, Nevis kills the dying Anittas.

Meanwhile, Waan, Lion, and Tuf have found the armory, but have split up due to disagreements on leadership. They quickly discover that the air is poisoned with various plagues, which Waan determines using one of Tuf's cats, Mushroom. Tuf recognises that Mushroom is infected by the plagues and is dying, and kills him gently, preventing Mushroom's further suffering. He discovers the cloning room of the seedship, and clones Mushroom using the ship's equipment, naming the new cat Chaos.

Waan is found by the hellkittens, which spray her with acid and corrode her helmet, impairing her vision. Disbelieving Tuf's warning, she takes her helmet off and contracts a plague. When the hellkittens return to eat her, she is not only weakened by illness but unprotected by her helmet. Though mostly paralysed and dying, she manages to activate a grenade, destroying herself along with the hellkittens.

Lion, meanwhile, sets a trap for Nevis in a corridor by rigging a plasma cannon to go off only when objects of certain dimensions, such as Nevis's battle-suit, pass in front of it. While luring Nevis toward the trap, however, he is killed and partly eaten by the bat-like creature.

Rica Dawnstar, in charge of the control room, uses reverse psychology to trick Nevis into meeting the walking web, which kills him. She then offers Tuf the chance to leave peacefully, but on his refusal, attempts to kill him with the psi-controlled t-rex. But Tuf has discovered Lion's plasma-cannon trap; he lures Dawnstar and the dinosaur into its line of fire, killing them. Tuf then takes control of the seedship as the only surviving claimant.[2]

"Loaves and Fishes"

Haviland Tuf takes his newly-acquired seedship, which he has named the Ark, to the world of S'uthlam (an anagram for Malthus) for extensive repairs. S'uthlam is a world on the verge of war with all of the nearby inhabited worlds, as it requires a constant flow of resources to the planet. This is due to the world's continuing population explosion, a result of the S'uthlamese religious belief that unfettered and unchecked human reproduction will one day lead to a world of gods. This is in spite of evidence that this population explosion will lead, as it has many times in the past, to famine and S'uthlamese attempts at military conquest of adjoining star systems.

Once the S'uthlamese become aware of the Ark and its capabilities, they want to seize it for themselves to use it as both a resource to wring higher caloric production from their star system's biology, and also as a powerful weapon of war. In an attempt to secure it, Portmaster Tolly Mune kidnaps one of Tuf's cats. She makes a bet with Tuf - if he will solve S'uthlam's impending famine, she will return his cat and give him monetary credits for the ship's repairs. If he loses the bet, S'uthlam will keep the seedship.

Tuf at first reasonably proposes that the S'uthlamese simply restrict their incontinent reproductive practices, but because the S'uthlamese fixation is fanatic, it is impervious to reason. They will not control their population growth, and thus drive obsessively into a suicidal future of starvation and war.

Tuf works on the problem, and manages to find a solution whereby he uses the seedship's capabilities to provide exotic plants and animals which can yield sustenance for the population, thus staving off starvation for a period of time. The authorities, with striking proof of the Ark's capabilities, now begin scheming to bring it in their possession. Mune, disgusted with the politics of the situation, assists Tuf in escaping from S'uthlam, despite the fact that this places her in a precarious position. He informs her that he will return to pay off his debt.[3]


Tuf finds himself at Namor, an oceanic world where sea monsters are attacking the local population. As always, he offers to assist for a fee. Before diving into creating the creatures needed to battle the monsters, Tuf begins to study the planet in order to determine why the monsters are attacking the people of Namor. However, during this study, the Namorians grow more desperate and impatient, especially as monsters able to walk on land begin to appear. Tuf's hand is forced, and he unleashes a barrage of other creatures to directly counteract the monsters.

This strategy, initially successful, soon fails as the monsters gain resistance to these otherworldly creatures. Tuf goes back to work, and manages to find a solution. Through his psionically-enhanced cat, he discovers a previously-unsuspected sapient species native to Namor: the mudpots. Sessile, aquatic bottom-dwellers (which had hitherto been considered dietary delicacies by the Namorian colonists), they are linked telepathically into a kind of hivemind, controlling the lesser species of life on the planet as skilled bio-engineers.

Tuf establishes communications with the mudpots and brokers a peace agreement whereby his human employers agree to cease eating the planet's autochthonous intelligent species. He gives the leaders of Namor psionically-enhanced kittens to facilitate their dealings with the mudpots, and departs.[4]

"Second Helpings"

Tuf returns to S'uthlam to pay the first part of his debt. He is hailed as a hero due to the advancements in the overcrowded world's food production, now known as "Tuf's Flowering". This is also due to Tuf and Mune, a highly inaccurate, overly-dramatized movie about Tuf's first adventure on S'uthlam, the creation of which Mune encouraged to build public support for Tuf's plan (and save her political skin from the fallout of helping Tuf escape with Ark).

However, paradoxically, the overpopulation crisis has become even worse due to the S'uthlamese people's over-optimistic response to Tuf's Flowering, increasing their reproduction rates. Tuf works on trying to provide even more-efficient crops and animals. He also insists on delivering a planet-wide speech detailing the enhancements he had in mind for S'uthlam and concluding with an explicit admonition of their lack of birth control. This is received with predictable religious outrage, and Mune is barely able to extract Tuf from the clutches of an angry S'uthlamese mob.[5]

"A Beast for Norn"

Tuf is approached by Herold Norn, senior beastmaster of the Norn House of Lyronica. The House of Norn requests beasts for gladiatorial fighting in Lyronica's Bronze Arena. After seeing an example of the Arena battles (and, it is strongly implied, being appalled by its barbarity), Tuf agrees to provide a breeding stock of cobalcats (and a stock of innocuous-looking prey animals from the cobalcats' homeworld to be released into the cobalcats' new Lyronican habitat) for the House of Norn.

As the House of Norn racks up victories with their cobalcats, Tuf is approached seriatim by the other houses for ever-more-lethally-effective beasts (and compatible prey animals), until the greatest of the Houses, namely House Arneth-in-the-Gilded-Wood at last approaches him for a beast and also with a demand for him to cease all further dealings with the Houses of Lyronica. Tuf graciously accepts the offer.

Norn returns to Tuf to complain about the cobalcats not mating (and about the prey species reproducing without effective suppression and overrunning the Norn lands, making it impossible for the House of Norn to return to breeding their original Arena beasts). Tuf gets the last laugh, as the introduction of the various prey species into each House's territory irrevocably changes the regional ecosystem such that all become incapable of sustaining the large predators upon which the gladiatorial contests had originally depended, thus leading to the (unstated) end of the Bronze Arena.[6]

"Call Him Moses"

While peaceably eating in a restaurant, Tuf is attacked by Jaime Kreen. Kreen is convicted for the attack and bonded to Tuf as a servant in debt. Kreen explains that his society (a technologically advanced secondary colony established as an arcology on the planet Charity) has been taken over by a primitivist religious leader named Moses. Taking his cues from the Bible, Moses had unleashed plagues on the inhabitants of the arcology, driving them out of their city into the countryside to labour and suffer under Moses' back-to-nature Holy Altruistic Restoration.

Kreen had attempted to murder Tuf because he blames Moses' plagues upon Tuf, who has gained an interstellar reputation as an ecological engineer, and Tuf realizes that Moses' "plagues" (actually low-tech simulations easily imposed by sabotage upon the closed system of an arcology) offer him an opportunity for revenue.

Kreen is sent down to the planet to bring back the former leaders of the now-conquered and evacuated arcology for negotiations, and Tuf offers to help them against Moses for a hefty fee. Using the Ark's technology, Tuf introduces himself to Moses as God, in the guise of a pillar of fire. He afflicts the followers of Moses with the Biblical plagues of legend, but these are widespread planetary ecological assaults instead of Moses' fraudulent localized afflictions.

After two such attacks, Tuf invites Moses aboard the Ark and shows him simulations of the increasingly horrible plagues that he could further inflict upon Moses and his followers. Moses, frightened, gives up his claim on the arcology's population, allowing them to escape his nasty, brutish religious fanaticism and return to the comforts of modern civilization.[7]

"Manna from Heaven"

Tuf returns to S'uthlam for the third time to pay off the last of his debt. This time, S'uthlam is on the brink of war with the allied forces of the neighboring worlds. Mune, now First Councillor or planetary leader, comes aboard the Ark to discuss with Tuf the possibility of acquiring the seedship for S'uthlam's own purposes.

S'uthlam's population problem remains, worse than ever, as Tuf's innovations from his previous visit were not maximally used. Its society is beginning to break down and either a terrible war or utter social collapse seems likely. Tuf labours to find a solution, and calls a meeting of all the worlds about to clash. He presents to them his solution: an edible, mildly addictive plant called "manna", which will freely grow everywhere on S'uthlam and eliminate its hunger problems. After some arm-twisting, in which Tuf threatens to use the military might of his seedship against anyone who refuses, the hostile worlds agree to an armistice. Tuf later tells a horrified Mune that the manna will indeed feed her people, but will also inhibit the libidos of the S'uthlamese and cause widespread, but not universal, infertility. He leaves Mune to make a momentous decision for S'uthlam; it is implied that she accepts the provision of manna to forestall war and famine.[8]



Artwork by Raoul Vitale

Tuf Voyaging has been described as a darkly comic meditation on environmentalism, interventionism, and absolute power.

According Wikipedia, the novel begins with Tuf as an "unassuming and rather inept interstellar trader, of humble and somewhat bland (on the surface) nature, with an aversion to human contact, and a love of cats." As the story progresses, Tuf's character is revealed to embody H. Beam Piper's "self-reliant man," as the power of the Ark allows him to solve the apparently intractable problems of several worlds. Mune, in explaining why she was helping him escape with the Ark in the first of the S'uthlam stories, says that "Power corrupts . . . and absolute power corrupts absolutely" (an uncredited quotation of the ancient dictum by Lord Acton). Mune further says that she doesn't think that there is such a thing as an incorruptible man, but if there is, Tuf is it. She also says that she wouldn't trust the leaders of her world with the potentially terrible biowarfare capabilities of Ark.

Eventually this becomes a grim prediction. Finding that most of his clients' problems arise not primarily from true ecological catastrophes but rather as the result of their "cupidity, stupidity, bureaucracy, religious fanaticism and bloody-mindedness," he resolves their situations by addressing their failings, beginning (in the earliest published story, "A Beast for Norn") with rendering it impossible for the Great Houses of Lyronica to continue the gladiatorial animal contests of the Bronze Arena.

On Namor, Tuf finds a solution: seeking out contact with the previously unsuspected native sapient race that had escaped the "fighting guild" of unthinkingly truculent Guardians to end the attacks being inflicted upon the human colonists by the planet's mudpot hivemind. On Charity, he copes with both the incompetence of the arcology's administrators ("[Y]ou are by training a bureaucrat", says Tuf to Kreen, "and thus good for virtually nothing") and the religious tyranny of Moses' Holy Altruistic Restoration.

Finally, in "Manna from Heaven," he provides the S'uthlamese and their enemies with an irrevocable solution that simultaneously averts both famine and war but covertly imposes birth control upon the "religious crazies" of S'uthlam's Church of Life Evolving (characterised as "anti-entropists, kiddie-culters, helix-humpers, genepool puddlers"), forcing Mune to accept Tuf's induced population implosion as the only alternative to social breakdown and genocide. [9]

Nathaniel Katz from The Hat Rack identifies the core dilemna that Tuf faces throughout the novel: the fact that "it is not enough--and is not even possible--to simply solve the environmental symptoms of the problems that he encounters." That is, he can liberate the people he finds from the consequences of their mistakes, but he knows that, as he departs, "they will make those mistakes again." And so Tuf changes again, and "he begins to alter the people themselves." Witnessing a universe filled with problems, and aware that he has the ability to solve them, he intervenes. It's something he must do, he argues, no matter how much the people of that world wish him not to. Tuf declares that: "Failure to decide, because you lack the right, is itself a decision." He remakes the worlds around him to match his own ideas of progress.[10]

Author's Notes

Since he was a young writer, Martin dreamed of establishing a popular, long-running series. He notes that while many of the early series he began, such as the "Star Ring" series, the "Corpse Handler" series, and the Windhaven series (with Lisa Tuttle), were never completed, Tuf Voyaging is the exception. He credits Tuf with breaking his "series bugaboo" and "opened up the gates for Wild Cards and A Song of Ice and Fire."

Martin recalls that in 1975, ecology was a popular topic of discussion. He thought that a series about a biogenetic engineer travelling through space solving ecological problems "would offer no end of story possibilities." And more importantly, it was an idea that had never been done before.

Martin claims that Haviland Tuf is a mix of some of his favourite literary characters, such as Sherlock Holmes, Magnus Ridoplh, Nicholas van Rijn, and Hercule Poirot, as well as the filmmaker Alfred Hitchcock. He chose the name "Haviland" after seeing it on the wall chart of a chess tournament that he was directing. Martin claims that of all his protagonists, Tuf is the least like himself, apart from the fact that they both owned a cat named Dax.

Martin credits the creation of Tuf Voyaging to former Analog assistant editor Betsy Mitchell, who encouraged him to write a full collection of Haviland Tuf's adventures. With his third book, Armaggedon Rag selling poorly, Martin's career was in trouble, and so he took Mitchell up on her offer.

Martin recalls that a sequel to Tuf Voyaging was planned, either another collection of stories or a full-length novel. The book was even announced in Locus magazine, with the working titles being Twice as Tuf or Tuf Landing. However, Martin had moved to Los Angeles at that point, where television studios were offering him far higher salaries than book publishers.

In a February 2013 post, Martin wrote on his website that, from time to time, he is asked by fans about writing more Tuf stories, and said that he hopes to do so again someday.[11]

Publication History

Tuf Voyaging is fix-up novel, meaning it is a collection of related short fiction works, originally published seperately. The publication history of the chapters was:

  • "A Beast for Norn" (Andromeda I, May 1976)
  • "Call Him Moses" (Analog Science Fiction and Fact, February 1978)
  • "Guardians" (Analog Science Fiction and Fact, October 1981)
  • "The Plague Star" (Analog Science Fiction and Fact, January/February 1985)
  • "Loaves and Fishes" (Analog Science Fiction and Fact, October 1985)
  • "Second Helpings" (Analog Science Fiction and Fact, November 1985)
  • "Manna from Heaven" (Analog Science Fiction and Fact, December 1985)

The book includes a prologue and Martin's S'uthlam storyline (originally published in Analog Science Fiction and Fact), adding them as bridging material, and gathering them with the other Tuf stories into one episodic novel.

The original 1975 version of A Beast for Norm was revised and expanded for the 1986 novel, in order to--as Martin writes--"bring the proto-­Tuf more in line with the character as he’d evolved in the later stories." However, the original version of the story can still be read in Martin's 2003 anthology Dreamsongs.


In 2007, Martin's short story anthology Dreamsongs was released in audiobook format. It included recordings of "A Beast for Norn" and "Guardians," both read by Roy Doltrice.

"Guardians" by George R. R. Martin (audiobook)

Thus far there have been no film or televisual adaptations of Tuf Voyaging. However, Martin has hinted that he thinks Irish actor Conleth Hill, who plays Varys on HBO's Game of Thrones, based on his bestselling A Song of Ice and Fire fantasy series, would be a good choice to play Tuf.


In 1981, "Guardians" was nominated for the Analog Award for Best Novella/Novelette. In 1982, it won the Locus Award for Best Novelette and was nominated for the Hugo Award for Best Novelette.

In 1985, "Loaves and Fishes" won the Analog Readers Poll for Best Novella/Novelette, while "Manna From Heaven" took second place. In 1986, "Manna from Heaven" was also nominated for the Locus Award for Best Novella.

In 1986, "The Plague Star" was nominated for the Analog Award for Best Serial Novel or Novella. In 1987, it was nominated for the Locus Award for Best Novella.

In 1987, Tuf Voyaging was nominated for the Locus Award for Best Collection.

In 2006, Tuf Voyaging was nominated for a Seiun Award in Japan for Best Translated Novel.

Connections to the "Thousand Worlds" Universe

Tuf Voyaging is set across several familiar regions of the "Thousand Worlds" universe, including ShanDellor, Hro B’rana, Namor and Tamber in the Jambles, S'uthlam in Fyndii Space, and Lyronica in the Manrealm. It is not clear where the planet of Charity is located.

Several characters state that the Double War ended a thousand years ago, which would place Tuf Voyaging around ai-1000. This would make it the most recent story to occur in the "Thousand Worlds" timeline, taking place over a thousand years after The Hero and Men of Greywater Station; four hundred years after Dying of the Light; two hundred and fifty years after The Glass Flower; and two hundred years after The Stone City.

Tuf's ship, the Ark, is an abandoned seedship of the long-defunct Federal Empire's Ecological Engineering Corps, once deployed in their war against the Hrangan Empire. Such ships were developed at the Corps' headquarters on Prometheus, and would spread disease, insects, and plant and animal pests among the enemies of Earth. They were incredibly powerful, capable of rewriting genetic coding for entire planets; however, much of the knowledge that created the technology was lost with the collapse of the Empire and the resulting Interregnum.

In "A Beast for Norn," Tuf breeds a stock cobal panthers that are native to Celia’s World. Celia’s World is also mentioned in The Stone City, The Way of Cross and Dragon and Sandkings.

The stories mentions duralloy and viewscreens, technology which is ubiquitous throughout the "Thousand Worlds" universe.
