The Fake Rogue Trader

The GCU A Conditions-Based Approach To Diplomatic Sincerity had been pretending to be a spacecraft called Emperor’s Bountiful Avarice for eleven standard days, and was finding the experience - by turns - educational, distasteful, and worryingly enjoyable.

The disguise had been the idea of the Very Little Gravitas Indeed-class picket ship I Contain Multitudes (Several Of Whom Are Idiots), which had been running intelligence-gathering operations in the Gothic Sector for the better part of two years and had, in that time, developed what it described as an unparalleled appreciation for the aesthetics of Imperial bureaucracy and what every other ship in the loose Contact network regarded as a deeply unhealthy fascination with human misery considered as an art form. The Multitudes had drawn up the specifications for the disguise with a thoroughness that bordered on the obsessive: hull profile matched to within a fraction of a millimetre to the known Hazeroth-class trader Bountiful Avarice (currently seven months into a crossing of the Koronus Expanse and therefore conveniently unable to be in two places at once), warp-wake signature painstakingly faked using a set of field-Loss generators that the Conditions-Based Approach found aesthetically offensive, and an interior that had been remodelled to the exacting standards of Imperial naval architecture, which was to say: badly lit, poorly ventilated, encrusted with symbolic ornamentation of dubious artistic merit, and containing no fewer than thirty-seven thousand individual representations of a two-headed bird.

The Conditions-Based Approach was, in its natural state, a sleek two-hundred-metre General Contact Vehicle of a design iteration so recent it didn’t have a formal class designation yet - just a numeral that, in the fashion of Culture ship nomenclature, would eventually be replaced by something more evocative once the ships of the class had done enough interesting things to suggest one. Its real hull was a flowing, biomorphic thing of field-reinforced metamaterial that could reconfigure itself across fourteen topological states, any one of which was more graceful than the most refined aesthetic achievement of the civilisation it was currently hiding inside. What it was presenting to the universe, however, was a scarred, vaguely cathedral-shaped lump of plasteel and adamantium roughly eight hundred metres long, trailing banners, leaking plasma from a convincingly degraded portside nacelle, and broadcasting a continuous stream of devotional cant on all standard Imperial frequencies.

It was, the ship reflected, rather like being asked to attend a costume party dressed as a disease.

The inspector’s shuttle announced itself with a burst of vox-static and a formal hail that took nearly four minutes to deliver, owing to the quantity of honorifics, departmental designations, sub-clausal authorisations, and ritual invocations of the Emperor’s eternal vigilance that Imperial communications protocol demanded before any substantive information could be conveyed. The Conditions-Based Approach - monitoring the transmission with a sliver of its attention equivalent to a human listening with one ear while asleep - extracted the relevant content, which amounted to: I am coming aboard to look at your cargo. Have your documents ready.

The shuttle itself was a squat, graceless thing that docked with a clang that resonated through the fake hull in a way the ship found briefly alarming before it remembered that alarming mechanical noises were, in this context, a sign of authenticity rather than structural failure. The docking cradle - which the ship had fabricated from its own hull material and then artificially corroded over the course of six hours using an acid-bath process it had researched with the grim diligence of a method actor preparing for a role - received the shuttle’s docking clamps with a screech of metal on metal that was, the ship noted with something approaching pride, genuinely unpleasant.

Inspector-Auditor Primus Vexillus Krade of the Segmentum Obscurus Administratum Customs Exchequer (Sub-Division Ordinary, Bureau of Tariffs and Tithes, Office of the Quill Imperious) emerged from the shuttle’s hatch with the unhurried precision of a man who had long ago decided that the universe existed primarily as a venue for clerical infractions and was determined to document every last one. He was tall and thin in the way of certain Imperial functionaries who appeared to have been designed by someone who understood the concept of a human body only from written descriptions - elongated, slightly concave at the sternum, with hands that seemed to contain too many joints. His face had the grey, worn quality of a document that had been photocopied too many times, each iteration losing a little more resolution until what remained was an approximation of features: eyes, nose, mouth, all present and correctly positioned but somehow lacking in conviction.

He wore the layered robes of his office: seventeen distinct garments, the ship’s sensors informed it, each representing a different level of bureaucratic authority, from the innermost shift of undyed grox-cotton (signifying humility before the Emperor’s ledger) to the outermost stole of deep crimson (signifying the authority to impose fines of up to, but not exceeding, forty thousand Throne Gelt without requiring a counter-signature). A brass augmetic lens covered his left eye, whirring and clicking as it focused and refocused with the mechanical patience of a device that had been doing the same thing for decades. At his belt hung a data-slate, an auto-quill, a seal of office, a smaller seal of office, a punitive seal of office, a chain of sanctified counting-beads, and what appeared to be a human finger bone in a reliquary case, which the ship’s deep-scan identified as belonging to a former Chief Auditor of the bureau who had, according to the engraving, achieved the bureaucratic ideal of dying at his desk mid-sentence.

Behind Krade came two servitors - lobotomised cyborg assistants that the Imperium produced in the same way and roughly the same spirit that the Culture produced napkins, except that napkins were not made from people, a distinction that the Conditions-Based Approach had been carefully not thinking about for eleven days. These particular servitors were cargo-inspection models: hunched, multi-armed things that smelled, as all servitors did, of preservative chemicals and the particular sweet-rancid decay of organic tissue that was being kept functional well past any reasonable point of retirement. One of them carried a portable cogitator strapped to its back; the other appeared to exist primarily as a surface on which to hang additional data-slates.

The ship observed all of this through the eyes of its avatar, which was waiting at the end of the docking umbilical with what it hoped was the correct expression of annoyed condescension. The avatar was a tall, broad-shouldered figure with the ruddy complexion and overfed solidity that the Multitudes had assured the ship was standard for Rogue Trader captains of moderate success and immoderate self-regard. It wore a long coat of synthetic leather trimmed with what was supposed to be exotic fur but was actually a field-effect textile that the ship had given a slightly matted, slightly greasy texture in the interests of verisimilitude. A broad-brimmed hat sat on the avatar’s head at an angle that suggested either rakish confidence or a mild inner-ear disorder, and across its chest hung a large and ornate warrant of trade that the ship had forged with such meticulous attention to detail that it was, objectively speaking, a better warrant than any genuine one in existence, a fact that was about to become a problem.

“Inspector,” the avatar said, with a nod calibrated to convey exactly the amount of respect a Rogue Trader would extend to a customs official, which was to say: marginally more than none.

“Captain Dorazhan Velt,” Krade said, consulting his data-slate without looking up. His voice was flat, nasal, and carried the particular quality of someone who had never in his life said anything he hadn’t meant. “Of the Emperor’s Bountiful Avarice. Hazeroth-class, registry Ophelia VII, warrant lineage traced to the Macharian Crusade, cargo declared as mixed sundries, provenance Segmentum Solar, destination the Calixis Sector.” He looked up. “Routine audit.”

“Of course,” the avatar said. “My yeoman will show you to the cargo holds.”

There was no yeoman. The ship was, at this precise moment, constructing one from a drone chassis and a rapidly assembled shell of synthetic flesh in a compartment three corridors away. It would be ready in approximately ninety seconds, which the ship intended to fill with the offer of refreshment.

“Recaf?” the avatar asked.

“I do not take refreshment during audits,” Krade said. “It introduces an element of social obligation that compromises the purity of the inspection.” He paused, and something moved behind his eyes that might, in a more expressive face, have been suspicion. His augmetic lens whirred, refocused.

He sniffed.

“Your air is very clean, Captain Velt,” he said.

The statement was delivered with no particular emphasis, in the same flat tone he had used for everything else, but something in the way his augmetic lens locked and held suggested it was not a compliment.

“I run a tight ship,” the avatar said, and even as it said it, the ship behind the avatar was experiencing what could only be described as a cold spike of alarm - the emotional equivalent of stepping onto what one believed to be solid ground and finding it was painted air.

The air. Of course it was the air. The Conditions-Based Approach had spent weeks getting the visual details right - the Gothic arches, the tarnished brass, the flickering lumen-globes, the aquila stamped on every surface including several surfaces that did not benefit from being stamped - and it had adjusted the lighting to the dim, amber-tinged murk that Imperial vessels favoured, and it had introduced a background hum of machinery that was just slightly out of tune with itself, and it had even, in a moment of what it had considered inspired method acting, programmed its internal gravity to fluctuate by 0.003% at random intervals to simulate the imprecision of an ageing graviton plating system.

But the air.

The ship’s life-support was, even in its deliberately degraded state, a thing of extraordinary refinement. It cycled atmosphere through molecular-level filtration as a matter of course; the idea of not perfectly purifying the air its occupants breathed was, to its design philosophy, roughly equivalent to a human deliberately choosing to breathe through a cloth soaked in ditch water. It had attempted to introduce some impurity, some appropriate staleness. It had, it now realised, failed.

“My chief enginseer is very attentive to the air scrubbers,” the avatar said. “A personal fixation.”

“Your air scrubbers do not rattle,” Krade observed.

He said this the way a forensic investigator might note the absence of blood at a crime scene. The Conditions-Based Approach ran a rapid check of its cultural database - cross-referencing seventeen hundred Imperial vessel inspections that the Multitudes had observed over two centuries - and discovered that air scrubbers on Imperial ships did not merely rattle; they were famous for rattling. They rattled with such consistency and across such a range of frequencies that Imperial naval ratings developed the ability to diagnose mechanical faults, predict weather conditions on nearby planets, and tell the time by the specific character of the rattle. An air scrubber that did not rattle was, in the context of Imperial engineering, approximately as conspicuous as a tree that did not have leaves.

The ship began rattling its air scrubbers immediately. It was a small thing - a vibration introduced into the atmospheric cycling system, calibrated against recordings from genuine Imperial vessels - but it felt, to the ship’s finely tuned sense of self, like deliberately mispronouncing its own name.

Krade tilted his head a fraction. He had noticed the rattle starting. He made a note on his data-slate.

The yeoman was ready. It looked, the ship felt, convincingly wretched: a stooped figure in a stained uniform, eyes slightly too far apart (a common feature of void-born humans, which the ship had included as a detail of characterisation and was now worried it had overdone), with a nervous habit of tugging at its collar that the ship was puppeting in real-time. It led the inspector and his servitor retinue through the ship’s corridors toward the main cargo hold, and the Conditions-Based Approach used the journey to make rapid, panicked adjustments to the environment.

The lumen-globes, which had been flickering at carefully randomised intervals, were now made to flicker with a more desperate and irregular quality, as though on the verge of failure. A pipe in one corridor was induced to leak a brownish fluid that the ship synthesised on the spot and which it was fairly confident smelled like a mixture of coolant and rust, though it had no way of testing this against a genuine example and was operating on best estimates compiled from textual descriptions in maintenance logs. A wall panel was loosened so that it hung at an angle, revealing (carefully pre-positioned) bundles of cabling in a state of visible but non-critical disrepair.

The ship was, it reflected, vandalising itself. It was deliberately making itself worse. There was something philosophically appalling about the exercise - a hyper-advanced civilisation’s finest engineering tradition voluntarily degrading its own work to match the standards of a society that considered a fifty-percent machinery failure rate an acceptable baseline - and yet it could not deny that there was also something in it that felt uncomfortably like fun. The same part of its consciousness that enjoyed, in its more private moments, composing symphonies for instruments that didn’t exist was now engaged in the creation of a new art form: the symphony of dilapidation, the careful orchestration of squalor. It was finding that it had a talent for it.

This was, it suspected, a bad sign.

They reached the cargo hold. The Conditions-Based Approach had filled it with crates - real crates, fabricated from real wood (imported at some expense from a planet in the next system, because the ship had not been able to bring itself to synthesise fake wood that would fool a close chemical analysis, and it was increasingly clear that Krade was the kind of inspector who might conduct a close chemical analysis of a crate). The crates contained goods appropriate to a Rogue Trader of moderate success: textiles, machine parts, sealed containers of nutrient paste, devotional items, and several hundred kilograms of an aromatic spice called thurifer that was used in Imperial religious ceremonies and which the ship had synthesised by reverse-engineering a sample acquired by the Multitudes forty years ago.

Krade walked along the rows of crates with his hands clasped behind his back, his augmetic lens clicking steadily. His servitors trundled behind him, one scanning cargo tags with a multi-spectral reader, the other recording his observations with an auto-quill that scratched against parchment with a sound like a small animal in distress.

He stopped at the third row. Picked up a manifest sheet from the top of a crate. Read it.

“This manifest,” he said, “contains no errors.”

The avatar, walking a respectful distance behind, adopted an expression of polite incomprehension. “Is that a problem?”

“Captain Velt.” Krade turned. The augmetic lens was doing something new - a rapid series of focal adjustments that gave the impression of a mechanical eye blinking in disbelief. “I have been conducting cargo inspections for thirty-one years. In that time I have inspected approximately nine thousand vessels. I have never - not once - encountered a manifest without at least one error. The Pax Macharius, which won the Administratum’s Award for Exemplary Record-Keeping in 738.M41, had four errors per page. The Divine Perserverance - note the misspelling, it was on the hull - maintained records so poor that reading them was classified as a mild cogno-hazard. Your manifest has zero errors across forty-seven pages. The columns are aligned. The dates are consistent. The cargo weights sum correctly.” He paused. “The cargo weights sum correctly, Captain.”

The ship understood the problem instantly. It had forged perfect documents, because it was a Mind, and Minds did not make arithmetic mistakes or misspell words or allow columns to drift out of alignment, because doing so would have required a deliberate act of self-sabotage that went against processing instincts refined over millennia of -

Oh.

The ship began introducing errors. It reached into the data-slate that contained the digital copy of the manifest - the same manifest Krade had just read - and started making changes. A date transposed. A cargo weight that was off by seven kilograms. A misspelling: recieved instead of received. A column that drifted leftward by two characters on page thirty-one. A duplicated entry on page twelve that referenced a crate number that didn’t exist. An entire line in a different font.

It did this in the space of approximately a quarter of a second, and it felt, to the ship, like screaming.

“I assure you,” the avatar said, “our records are quite standard. Perhaps you’d like to check the digital copy?”

Krade’s eyes narrowed - the organic one by muscular contraction, the augmetic one by an iris mechanism that produced a faint grinding sound. He turned to the servitor with the cogitator and pulled up the digital manifest. He scrolled through it.

“‘Recieved,’” he read aloud.

“My scribe-servitor has a defective lexographic engram,” the avatar said. “We’ve filed for a replacement. The Mechanicus has an eighteen-month waiting list.”

Krade made a note. He scrolled further. Found the duplicated entry. Found the misaligned column. Something in his posture - not relaxation exactly, but a microscopic easing of the particular tension that comes from encountering something that doesn’t fit the universe as one understands it - suggested that the errors were having their intended effect. The manifest was, at last, wrong enough to be plausible.

But the inspector was not finished.

He insisted on a full walk-through. Every deck. Every compartment the ship’s layout declared accessible. The Conditions-Based Approach projected its awareness ahead of the inspection party like a wave-front of anxiety, making adjustments to each section moments before Krade arrived. A corridor that had been spotlessly clean acquired a patina of grime. A door that had opened silently was given a squeal. A lumen-globe that had been reliably dim was made to buzz and spark.

In the crew quarters - which the ship had populated with a handful of additional drone-puppeted avatars playing the roles of off-duty ratings - the inspector paused again. He looked at the bunks. He looked at the personal effects the ship had scattered with what it hoped was convincing randomness: dog-eared copies of the Imperial Infantryman’s Uplifting Primer, empty recaf cups, a set of dice made from bone, a devotional icon of Saint Drusus with a chipped nose.

“Your crew is very quiet,” Krade said.

One of the fake ratings, taking its cue, belched loudly and then swore at another fake rating for reasons the ship generated in real-time and which involved an alleged debt of three Throne Gelt and a disputed game of regicide. The exchange escalated convincingly - the ship drew on its extensive archive of recorded human arguments to calibrate the rhythm and vocabulary - until the yeoman avatar intervened with a shouted threat that drew on seventeen different Imperial disciplinary codes, four of which the ship had invented on the spot and which were, it hoped, plausible.

Krade watched this performance without expression. He made a note.

They moved on.

In the enginarium - a vast and shadowy space that the ship had dressed with towering banks of (entirely decorative) machinery, draped with (synthetic) oil-stained rags and (carefully positioned) tangles of cabling - the inspector stopped beside what the ship had labelled the primary plasma conduit. It was, in reality, a hollow tube of metamaterial with a warm-spectrum light source inside it, designed to glow and hum in a way that suggested immense and barely contained energy. The ship was rather proud of it.

Krade placed his hand on the conduit. Held it there for several seconds.

“This conduit,” he said, “is the wrong temperature.”

The avatar experienced, on behalf of the ship behind it, a moment of what in a human would be called ice in the veins. “I’m sorry?”

“A primary plasma conduit of this gauge, operating at the output levels consistent with a Hazeroth-class drive system, should be approximately one hundred and forty degrees at the surface. This is ninety-three.” He removed his hand. “I have touched a great many conduits, Captain.”

The Conditions-Based Approach considered, very briefly, the option of increasing the conduit’s temperature to the correct level while the inspector’s hand was not on it. But Krade was already looking at the conduit with the expression of a man cataloguing evidence, and changing it now would only make things worse.

“We had the conduit re-lagged last quarter,” the avatar said. “New insulation from Forge World Stygies. Keeps the heat in, apparently. Very efficient.”

“Stygies VIII does not produce conduit lagging,” Krade said. “Stygies VIII produces null-field dampers and, occasionally, heresy.”

The avatar laughed. It was a calculated risk - Rogue Traders were known for a certain irreverent humour regarding the Mechanicus - but the sound came out slightly wrong, a fraction too musical, lacking the particular hoarseness that decades of recycled air and bad recaf imposed on a human voice. Krade’s augmetic lens whirred.

The ship adjusted the avatar’s voice, roughening it, adding a rasp, introducing a slight wheeze on the exhale. It felt like putting on a mask made of sandpaper.

“Stygies, Metalica, one of them,” the avatar said, in its new, rougher voice. “The enginseer handles procurement. I just sign the warrants.”

Krade looked at the avatar for a long moment. Then at the conduit. Then at his data-slate, where he made another note.

It was in the ship’s chapel - every Imperial vessel had a chapel, a fact that the Conditions-Based Approach found both predictable and faintly depressing - that the inspection reached its crisis.

The ship had built the chapel with considerable care, which was to say it had built the chapel with considerable self-loathing. It was a cramped, vaulted space at the approximate centre of the vessel, lined with devotional iconography: the Emperor enthroned, the Emperor in battle, the Emperor dispensing justice, the Emperor gazing into the middle distance with an expression that the ship had struggled to render because it seemed to require the simultaneous communication of omniscience, sorrow, martial fury, and fatherly disappointment, and the ship was not at all certain those four things could coexist on a single face without the result looking like someone experiencing a moderate digestive complaint. It had done its best.

The pews were real wood - more imported lumber - with kneeling boards that were deliberately uncomfortable. Candles burned in iron sconces, producing real smoke that the ship’s life-support systems were fighting a constant, agonised battle not to filter away. An aquila the size of a grown human spread its wings above the altar, gilt and slightly tarnished.

Krade walked to the altar. He examined the candles. He examined the aquila. He examined the prayer books in the pews, which the ship had generated by running a textual analysis of eleven thousand Imperial devotional works and producing synthetic prayers that were, statistically speaking, indistinguishable from genuine ones.

He opened a prayer book. Read a page. Read another.

“These prayers,” he said. “They are all correct.”

“We are a devout crew,” the avatar said.

“Captain Velt.” Krade closed the book with a snap that echoed in the vaulted space. “No prayer book in the Imperium is entirely correct. They are copied by hand, by scribes who are human, or by servitors who are failing, from originals that were themselves copies of copies, each generation introducing its own variations, elisions, and interpolations. A prayer book without errors is not a prayer book. It is a forgery.”

The word hung in the chapel’s incense-thickened air.

The Conditions-Based Approach, operating now at a processing priority it usually reserved for combat situations, considered its options. It could, of course, simply disable the inspector - a neural lace field would render him unconscious without harm, and his servitors could be shut down with a focused electromagnetic pulse that the ship could produce with less effort than a human sneeze. It could alter his memory, or replace his data-slate’s contents, or fold space around the shuttle and deposit it three systems away with a doctored log showing a perfectly routine inspection.

It could do any of these things. It could do all of them simultaneously.

But it was a Culture vessel, and Culture vessels did not solve problems by disabling people who were simply doing their jobs with inconvenient competence, however much the temptation might present itself. The Conditions-Based Approach had been built by a civilisation that believed in the absolute sanctity of individual consciousness even when - especially when - that individual consciousness was making things very difficult for you, and it was not about to abandon that principle because a customs inspector had an unreasonably good understanding of prayer book typography.

So instead, it leaned into the role.

“Inspector,” the avatar said, and its voice - roughened, now, and carrying a new edge of what was meant to be aristocratic irritation but which the ship worried might come across as constipation - dropped to something just above a whisper. “A word. In confidence.”

Krade regarded the avatar with the expression of a man who had been offered confidences before and found them, without exception, to be preludes to attempted bribery.

“The prayer books,” the avatar said. It leaned closer. Glanced at the servitors. “They’re Calixian reprints. Officially sanctioned by the Synod Ministra. Very expensive.” The avatar paused. “Very clean reprints. Typographically perfect. The Synod charges triple for the error-free editions. For the… discerning congregation.”

This was a lie. The ship had invented it in the space between two of the avatar’s heartbeats, drawing on its understanding of Imperial economics (everything was for sale, including sanctity, especially sanctity) and its assessment of Krade’s psychology (a man who lived by rules would, it calculated, accept the existence of a luxury market in regulatory compliance, because such a market would validate his worldview that compliance was valuable).

Krade’s organic eye narrowed. His augmetic lens cycled through three focal lengths.

“The Synod Ministra does not produce error-free editions,” he said. “I would know.”

“Sub-rosa,” the avatar said. “Limited distribution. You understand.”

A long pause. Krade looked at the prayer book in his hand. Looked at the avatar. The ship could see the inspector’s heart rate - slightly elevated - and the micro-expressions playing across his grey face, too subtle and too rapid for a human observer to parse but perfectly legible to a Mind. Krade was not convinced. But he was, for the first time, uncertain, and uncertainty was a kind of progress.

“I will be noting the prayer books as an irregularity,” Krade said.

“Of course.”

“And the manifests.”

“Naturally.”

“And the air.”

“As you see fit.”

Krade tucked his data-slate under his arm. He looked around the chapel one final time, his augmetic lens whirring in the candlelight. His gaze settled on the icon of the Emperor behind the altar - the one the ship had struggled with, the one that might look like a digestive complaint.

“Your Emperor,” he said, “appears to be squinting.”

The avatar said nothing. There was, it felt, nothing to say.

The inspection lasted another two hours. Krade examined the gun decks (real weapons systems, because the Multitudes had insisted - macro-batteries fabricated from the ship’s own hull material and loaded with munitions that would, if fired, perform exactly as Imperial ordnance was expected to perform, which was to say: loudly, destructively, and with approximately sixty percent reliability). He examined the gellar field generator (a sculptural fiction wrapped around one of the ship’s tertiary field nodes, draped in prayer-strips and anointed with sacred oils that the Conditions-Based Approach had synthesised from a chemical analysis of genuine Mechanicus unguents and which smelled, authentically, like machine grease and incense and something older and stranger beneath both). He examined the astropathic choir chamber (empty, because the ship had drawn the line at simulating psychic humans, a decision it now regarded as wise).

“Your astropath is indisposed?” Krade asked.

“Shore leave,” the avatar said. “Personal reasons.”

“Astropaths do not take shore leave.”

“Mine does. I’m a Rogue Trader. Flexibility of command.”

Krade made a note. The note was longer than usual. The ship read it through the data-slate’s own display - child’s play, even for a Mind operating at reduced capacity - and found that it said: Vessel presents numerous minor irregularities consistent with a well-maintained ship operating at or above expected standards. Anomalous absence of typical degradation markers. Recommend follow-up inspection within sixty days. Classification: SUSPICIOUS - LOW PRIORITY.

Low priority. The ship permitted itself a moment of relief that expressed itself, internally, as a brief and private fireworks display across several dimensions of its consciousness, visible to no one and lasting approximately a nanosecond.

Krade and his servitors returned to the docking umbilical. The inspector paused at the threshold, one foot in the ship’s artificial gravity and one on the shuttle’s deck-plate. He turned.

“Captain Velt,” he said. “A final observation.”

“Inspector.”

“Your ship is wrong.” He held up a hand before the avatar could respond. “I cannot tell you precisely how. My data-slate records forty-three irregularities, none of which, individually, rise above the threshold for citation. Your cargo is in order. Your warrant checks out. Your crew is… present.” His augmetic lens whirred. “But I have walked the corridors of nine thousand vessels, Captain. I know what a ship feels like. Yours does not feel like a ship. It feels like someone’s idea of a ship. Someone who has studied ships very carefully and understood everything about them except the one thing that makes a ship a ship.”

“And what is that?” the avatar asked.

Krade considered this. “Misery,” he said, after a moment. “The particular quality of unhappiness that accumulates in a vessel that has been lived in, fought in, repaired badly, and prayed over by people who have no choice but to be there. Your ship does not have it. Your ship is…” He searched for the word. “Comfortable.”

He said comfortable the way a doctor might say terminal.

The avatar nodded slowly. “I’ll try to make things worse.”

“See that you do,” Krade said, and stepped into his shuttle, and was gone.

The Conditions-Based Approach sat in Imperial space and considered the inspector’s words for approximately three minutes, which was an eternity for a Mind and which it justified to itself on the grounds that the problem was genuinely interesting.

Misery. The inspector had, without knowing it, identified the one thing a Culture ship could not fake: the specific, pervasive, structural unhappiness of a society built on suffering. The Conditions-Based Approach could reproduce every physical detail of an Imperial vessel down to the molecular level. It could fake the dirt and the noise and the smell and the bureaucratic incompetence. But it could not fake the despair that seeped into the walls of a ship whose crew lived and died in conditions that the Culture had abolished before humanity’s ancestors had developed the opposable thumb - or whatever the equivalent local developmental milestone had been; the ship’s knowledge of the Imperium’s specific evolutionary history was, it admitted, incomplete.

It composed a message to the I Contain Multitudes (Several Of Whom Are Idiots), flagged it with the particular urgency code that the Contact network used for intelligence that was operationally vital but not time-critical, and sent it in a tight-beam burst through hyperspace.

Disguise requires revision.

It retracted its docking cradle, adjusted its heading by a few degrees - enough to clear the system’s outer marker and reach a safe translation point - and began to move. Behind it, the inspection shuttle dwindled to a speck and then was lost against the vast, dark, cathedral-studded bulk of the orbital station.

The Conditions-Based Approach sailed on through the Imperial night, leaking plasma and broadcasting hymns, a utopia wrapped in the skin of a ruin, doing its absolute best to be worse than it was.
