List of Revelation Space characters

These are major characters from the various novels and stories that make up Alastair Reynolds's Revelation Space universe.

Revelation Space

Ana Khouri

Ana Khouri, an ex-soldier from Sky's Edge, was accidentally placed aboard an interstellar lighthugger and brought to Chasm City. At Chasm City, she participated in Shadowplay, a game in which she attempted to kill the clients so they could brag about the experience should they survive. After one Shadowplay event she was recruited by the Mademoiselle to infiltrate the crew of the lighthugger Nostalgia for Infinity. She was also recruited by the triumvirate of the Nostalgia for Infinity as the Gunnery officer (Triumvir Ilia Volyova's experiments having killed the previous officer), under the impression that she was heading back home to Sky's Edge. She has a small cameo at the end of Chasm City, although unnamed at the time and not revealed until Redemption Ark. She also has an important part in Redemption Ark organising the evacuation from Resurgam and again in Absolution Gap.

"Captain" John Brannigan

Possibly the oldest human character in the series, born in the 21st century. A victim of the melding plague, the Captain becomes more integrated with the ship Nostalgia for Infinity as the series progresses and ultimately becomes one with his ship. Afterwards he has erratic moods, attempting suicide with hell-class weapons, before eventually being coerced to convey the refugees from Resurgam and Ararat.

The Captain is a very mysterious character, hovering between wisdom and abject madness. He does have a respect for Clavain and is the only other 'person' who can compare with him in terms of age, wisdom and experience, although the Captain stated that he was already an old man when Clavain was born. The Captain at one point projects an image of himself from his oldest memories, in which he appears as a normal human in a spacesuit that is hinted at being very similar to those used by NASA astronauts, suggesting he originates from approximately our own time.

Throughout Redemption Ark and Absolution Gap, it is hinted that Captain Brannigan was responsible for many immoral acts in his very long, pre-plague life. Brannigan was also said to have been amongst the most extremely modified Ultras, likely able to survive prolonged vacuum exposure without a suit. Such was the degree of enhancement. By the time of the 'Eighty,' only Calvin Sylveste had the expertise to repair him, which he (or his beta-level) did on several occasions. Sometime before the events of Revelation Space the Captain was infected with the Melding Plague, but Ilia Voloyova was able to arrest the progress of the 'disease' by keeping him in a reefersleep casket. Eventually, the plague begins to consume the Captain, his casket, and nearby parts of the ship.

Volyova finds it is possible to converse with Brannigan by warming the core of his brain enough that other equipment can stimulate and read his mental activity. He is rarely lucid, and has little memory, but he provides Volyova with occasional companionship and insight during the 15 year journey to Delta Pavonis. During the journey to Resurgam, then to Hades, it is revealed to the reader that one of Brannigan's crimes was the murder of his first officer, Sajaki. During a visit to a Pattern Juggler world, Brannigan had Sajaki's neural pattern overwritten by his own – erasing Sajaki and effectively creating a duplicate of himself, ensuring his survival even if he was unable to recover from the Plague.

Volyova, on piecing together this crime, and requiring a force to counteract Sun Stealer's growing control over the ship, reveals her knowledge to Brannigan before destroying the medical equipment previously holding the Plague at bay. The Melding Plague affects the captain in a different way to other descriptions of the Plague in the Revelation Space series; he is somehow merged with the ship, in such a way that he retains his own consciousness, and demonstrates increasing control over the ship and its weapons. Unfortunately the psychological shock of being turned into a 4 kilometre long starship limits the captain's ability to act effectively.

The Captain sheds large parts of himself during a descent to Hela, where he intends to 'dock' with the planet and alter its orbit so that it rotates at exactly the same speed it orbits. Shortly after landing, Quaiche's soldiers infiltrate the Nostalgia for Infinity and begin to eradicate his presence within the ship. It is not known if the Captain dies during this invasion but it is considered very likely and Captain John Armstrong Brannigan is not mentioned again. Before he dies, however, he is able to activate the hypometric weapon and kill Grelier, who was holding Aura hostage.

Philip Lascaille

The first person to return alive from a visit to the Shrouders, the experience appears to make Lascaille autistic. He experiences a period of lucidity when he explains to Dan Sylveste how to be altered by the Pattern Jugglers to visit the Shrouders. Lascaille then apparently commits suicide, having completed the task the Shrouders had impressed upon him. In the later novel The Prefect, his alpha simulation becomes the intelligence inside The Clockmaker, and it is revealed that his "suicide" was actually murder.

The Mademoiselle

The Mademoiselle was an emissary of the Shrouders, possibly an artificial intelligence, who was imprinted on the brain of Carine Lefevre when the latter entered Lascaille's Shroud. She returned to Chasm City in Lefevre's body and secretly became a major underworld figure, with the ultimate goal of making sure Sun Stealer was prevented from provoking the Inhibitors. The Mademoiselle transfers a Beta simulation of herself to a disguised implant in Ana Khouri's head to ensure her mission in Revelation Space was completed. Her motivations are unclear, and her ruthlessness is apparent when she attempts to destroy a planet to keep the inhabitants from inadvertently alerting the Inhibitors. This Beta simulation was lost during the struggle against Sun Stealer for control of Nostalgia for Infinity and the Sun Stealer subsequently succeeded in reactivating the Inhibitors, although it was later destroyed by the humans on board the Nostalgia for Infinity.

Her original body was apparently killed by Sky Haussmann, but some remnant of her lived on inside Skade's brain (disguising itself as the voice of the "Night Council"). This manifestation, aware of the failure of the original Mademoiselle to destroy Sun Stealer, instead focused on attempting to ensure that the Conjoiners re-acquired the Cache Weapons in order to defeat the Inhibitors. She failed in this endeavour as well, and was presumably killed with Skade.

Triumvir Ilia Volyova

Triumvir Ilia Volyova of Nostalgia for Infinity is an implant-free Ultra, and a major character in both Revelation Space and Redemption Ark. At the beginning of Revelation Space, Volyova is the keeper of the Cache Weapons. It is during her search for a means to control these weapons that she enlists Ana Khouri (who was planted in the role by the Mademoiselle), thus setting off a chain of events that continues throughout the novels. She maintains a long friendship with Captain Brannigan, and is the only one to visit him regularly during several years of travel time on the Nostalgia for Infinity in which he is kept in very deep reefersleep to slow down the onset of Melding Plague in his body. She later disengages the reefersleep and warms him up fully, allowing his body to merge with the Nostalgia for Infinity as the only way to save it from an attack. Volyova later, in a plot hatched with Khouri, helps organize the evacuation of Resurgam, the first human-colonised planet doomed to be destroyed by the Inhibitors. She ultimately sacrifices herself to prevent the suicide of Captain Brannigan, now indistinguishable from the ship. In doing so, she exposes herself to vacuum, the damage proving almost fatal to her, but preserving the ship and thus the last chance of survival for the inhabitants of Resurgam.

She later dies on a suicide mission attacking the Inhibitors around Resurgam in an attempt to slow them down, giving the Nostalgia for Infinity the best possible chance of escape. Her actions apparently had no effect on the Inhibitors and all cache weapons that she took were wasted.

Calvin Sylveste

Calvin Sylveste, son of Lorean Sylveste and father to Dan, is a character that is referenced often in all books of the series, but is most prominent in Revelation Space. He is from an enormously wealthy family of scholars and industrialists, and was one of the most prominent and famous people in the Yellowstone Demarchy during the Belle Epoque.

He is mostly referred to because of the scandal of the Eighty. Calvin was an avid cyberneticist, and wished to find a way in which the human mind could be scanned and uploaded onto a computer matrix, from where it would retain sentience and become a true Alpha Level Simulation.

He rounded up eighty volunteers (including himself), all from distinguished families, to be subject to the most highly detailed neural scan in existence. However, the scan would have to be taken so fast that the brain would be permanently destroyed afterwards. The volunteers did not care much about what happened to their physical bodies once the scan had happened, so no-one had any disagreements. They expected to form a level of higher consciousness, Eighty above the rest of corporeal humanity, and so the experiments were called the Trans-Migration.

After the scans were taken, everything appeared to be correct and functioning. He had succeeded. But by one year after the first scan was initialised, and the last ones were being done, there was something wrong. The simulations started freezing, or entering paradoxical loops and shutting down. There was apparently a conceptual flaw in the scan's design, and none of the Alpha Levels survived except a few, Calvin being one along with Aurora Nerval Lermontov. It was deemed a mass murder on Sylveste's part and he went down in history as such.

Also, as he knew that the Trans-Migratory process had a chance of failure, he cloned himself years before his own scan, at the very beginning of his thoughts on the subject.

Dan Sylveste

Dan Sylveste, son of Calvin Sylveste and one of the central characters of Revelation Space. He is from an enormously wealthy family of scholars and industrialists, was driving force behind the Resurgam expedition and leader of the colony. He is a driven man who had come closer to penetrating a Shrouder enclave than anyone else living, but it is only after this experience that he develops an interest in the Delta Pavonis system.

At the beginning of Revelation Space he is an archaeologist working on Resurgam and studying the ruins of the ancient Amarantin, convinced that their history holds the key to why no alien species has yet survived long enough for humans to make contact. Resurgam may hold important clues, as it appears the entire planet surface was scoured by a coronal mass ejection from the otherwise stable star, just as the Amaratin were gaining spaceflight.

The Nostalgia for Infinity arrives in the system searching for Dan Sylveste so that he can heal Captain Brannigan, with the help of his father's Beta level simulation. It becomes apparent that Dan is a biological clone of his father, an immortality contingency plan that was never enacted. Sylveste is taken aboard the ship, which he has been on board before. Once he is aboard, traces of the Sun Stealer entity that have been aboard since that previous time are able to gain influence over the ship and Sylveste. Fighting breaks out for control of the ship.

Sylveste unwittingly, under the influence of Sun Stealer awakens the Inhibitors to the existence of mankind by triggering the inhibitor device left near the Hades object. Too late Dan realizes he is no longer in control and tries to destroy himself and the Inhibitor artifact with anti-lithium 'hot dust'.

He is eventually inducted into the Hades Matrix, an apparent neutron star that is actually a solid sphere of computronium, where he effectively becomes immortal as a component of the computronium.

Chasm City

Tanner Mirabel

Tanner Mirabel was a former soldier/assassin from Sky's Edge, later becoming security chief to arms trader Cahuella. A ruthlessly efficient and intelligent fighter, he fails to prevent an ambush, and accidentally causes the death of Cahuella's wife. His mind is subsequently trawled by Cahuella, his memories and identity used to create a disguise, allowing Cahuella to leave system seeking revenge, while Tanner is left for dead as punishment for his failures.

Most of our knowledge of Tanner comes from the stolen memories Cahuella implanted into himself, however these are increasingly tainted by the morality and character of Cahuella himself, making reliable character description difficult. When Tanner does, for a short while, appear in Chasm City, he seems considerably colder and more amoral than the version we see through the minds-eye of Cahuella. (Although it is implied that this is because of Cahuella's torture of him by feeding him to a hamadryad, an alien monster native to Sky's Edge). Tanner expertly kills Reivich near the end of Chasm City by throwing a knife into his head, a brief scuffle with Sky Haussmann ensues where Tanner is easily the stronger and more powerful antagonist. Tanner would have killed Sky, had he not been bitten in the neck by special fangs and venom glands implanted in Sky's mouth during his years under the identity of Cahuella.

Cahuella

Cahuella lived on Sky's Edge in a renovated zoological compound called the Reptile House, from where he sold weapons to both sides involved in the planet's civil war, which led to a bounty being placed on him for war crimes. Cahuella is fascinated by snakes and reptiles, and aims to capture an adult hamadryad to keep in the Reptile House, undertaking frequent hunting trips to achieve this aim.

In Chasm City it is told how he hired Tanner Mirabel to provide an expert level of security for himself and his wife, Gitta. However, Gitta is accidentally killed by Mirabel when she is taken hostage in a revenge attempt by Argent Reivich. In his grief, Cahuella tortures Mirabel by having him eaten alive by a near adult hamadryad (despite the fact that all terran species are poisonous to Hamadryads) then trawls his memories in order to pursue Reivich, believing Mirabel dead.

Toward the conclusion of Chasm City, we discover that Cahuella is in fact the immortal Sky Haussmann, who slept in reefersleep whilst his decoy was crucified.

Schuyler "Sky" Haussmann / "H"

In Chasm City, Sky Haussmann is the son of Titus Haussmann, the head of security aboard the Santiago. Sky discovers that he is not in fact his father's son, and was an infant 'momio' awakened by Titus secretly after the death of his own son. As such Sky Haussmann is immortal. Sky's story is told in a series of dreams as a counterpoint to the waking life that Tanner Mirabel experiences throughout Chasm City. The planet Sky's Edge was founded after the Flotilla of ships from Earth landed there and mockingly named in Sky's honour as a reminder of the action he took to ensure that the Santiago would be the first of the Flotilla to arrive.

Sky's greatest crime and best-known action was the ejection of entire rings of reefersleep caskets in order to gain an advantage in speed over the other craft of the Flotilla, destroying the "momios", or "sleepers", that were to be the colonists for the new world of Journey's End. This strategy meant the Santiago had less mass than the other ships and so could decelerate later and arrived at Journey's End first.

Because of his crime, Haussmann was apparently crucified after the other colonists landed on Sky's Edge. However, he managed to get a stand-in to be martyred, while Sky himself entered reefersleep for several decades, before eventually fleeing the planet.

Sky Haussmann is the centre of a pervasive cult, and those who worship him do so as if he were a god. This bizarre cult has developed an indoctrinal virus that alters the infected's perceptions, often giving them physical symptoms similar to stigmata or whole chapters of Sky's life as simulated experiences. The virus is designed to reprogram the victim, in a sense.

Sky shows up again as a minor character in Redemption Ark, but calls himself only "H"; he meets and allies with Nevil Clavain. He has killed and replaced the Mademoiselle for the 'greater good of the galaxy.' Haussman captures Clavain and convinces him of the best course of action to combat the Inhibitors. By aiding Clavain in his efforts to set up the expedition, largely responsible making possible for the successful evacuation of Resurgam and Clavain's efforts to save most of humanity.

Redemption Ark

Antoinette Bax

Antoinette Bax is a starship pilot in the Rust Belt. She is harassed by police authorities in the area until she rescues Clavain, which draws her into the conflict between Clavain and the Conjoiners. She goes with Clavain to Resurgam and Ararat and participates in the battle against Triumvir Volyova. During the events of Absolution Gap, the Nostalgia for Infinity leaves Ararat. Antoinette opts to remain on the planet and is thus caught in the inhibitor bombardment of the planet (although it is implied that the Pattern Jugglers may have absorbed her into the ocean before the bombardment commenced).

Nevil Clavain

Nevil Clavain is one of the oldest Conjoiners and can be credited with playing an overwhelming part in saving the human race from the Inhibitors. His actions throughout Redemption Ark set the scene for the evacuation of Resurgam and steers all factions of humanity towards stopping the Inhibitors. Born in the 22nd century, he originally fought against the Conjoiner faction as a senior military leader with the Coalition. In that role, he had designed orbital lasers set above Mars, and led assaults on the Conjoiners on Mars, earning the epithet the Butcher of Tharsis. He is captured at one point and held prisoner by Galiana for months, but she treats him well and refrains from infiltrating his mind with nanobots, to his surprise; instead she tries to convince him of the Conjoiners' merits, and eventually releases him.

Nevil later visits the Conjoiners as an ambassador to try to come to a peace deal, but he and the Conjoiners are sabotaged by a large force led by Nevil's brother Warren. After being injured in battle, he awakens to find that Galiana has interfaced nanobots with his brain as the only way to save him, as his brother has faked his death. In order to escape Mars and the invasion by the forces of Neural Purity, he accepted the full Conjoiner implants to allow for the Conjoiners escape of Mars, which requires a rapid deceleration into Mars's moon, Phobos. After a non-specific time, Clavin leaves with the rest of the Conjoiners in the first relativistic interstellar spacecraft that can carry live human beings. Before leaving Mars, Clavain meets and befriends Remontoire, and the two remain close and loyal friends for centuries.

Centuries later, Clavain does not use the newer Conjoiner implant technology as Skade and other Conjoiners do and continues to rely on his outdated and old implants, which enables him to escape a growing threat from a secret infiltration from within the Conjoiners, by a sinister personality that has taken control of Skade. Clavain defects from the compromised Conjoiners with the intention of joining the Demarchists. Clavain departs from the Yellowstone system for the Resurgam system along with several other Conjoiners and Underworld figures from Chasm City.

Clashing in the Resurgam system, Clavain's allies manage to stall Skade long enough for the colony to be evacuated. After 23 years of relative peace after founding a colony on the Juggler planet of Ararat, Clavain and Skade have their final encounter, where he accepts a deal with the dying Skade to allow a Caesarian section to be performed on her to recover the unborn Aura in exchange for the simultaneous torturing to the death of Clavain by the unwilling Scorpio. However, Clavain has the last laugh as he instructs Scorpio to bury him at sea, where the Pattern Jugglers absorb him and he is reunited with Galiana and Felka at last.

Skade

Skade appears in the book Redemption Ark and, to a lesser extent, in Absolution Gap. Skade is a Conjoiner, and one of the more recent ones. She is unusual amongst Conjoiners in that she has no fear of being away from the mother nest, having been trained in infiltration and special ops. She is a member of the Closed Council and also the Inner Sanctum, both executive bodies within the Conjoiner Mother Nest. Supposedly, she also works for the ultra-secret Night Council, although in Redemption Ark it is hinted that the Night Council does not exist at all as a Conjoiner body, but is actually an avatar for the mental structure of the Mademoiselle that infiltrated Skade's mind during a top secret mission to Chasm City.

Skade is expert at Conjoiner technology, being able to unleash neural attacks on other Conjoiners and peer past security divisions — even those within the minds of other Closed Council members. Clavain is the only person able to survive her attacks, doing so repeatedly throughout their encounters until he voluntarily allows her to enter his mind. He explains that her attacks were simply too sophisticated to penetrate his outdated implants- describing it as "like trying to hack into a clockwork calculator".

When Clavain flees the comet containing the Mother Nest, he snaps the anchor tethers of his ship rather than disengaging them from the comet's surface first, and one of them slices Skade in two through the upper torso. She survives with little more than her original head, mounted on an android body. Later, when a ship she is in is about to be destroyed by weapons deployed by Clavain, her ship jettisons an escape pod containing only her head, with an interface enabled to keep her head alive for long enough for the escape pod to rendezvous with another Conjoiner ship. At some point between Redemption Ark and Absolution Gap a new body is grown for her and her head is reattached.

Skade is later mortally wounded in battle on the planet Ararat, and makes a deal to allow the unborn Aura to be recovered from her womb before she dies in exchange for Nevil Clavain being tortured to death by Scorpio.

"Skade" means "harm" in Danish and Norwegian. Other Conjoiner characters, such as Remontoire and Clepsydra, also have meaningful names.

Warren Clavain

Warren Clavain is Nevil's older brother. Warren and Nevil are both senior military officers of the Coalition, which has long been in warfare with the Conjoiners. The war with the Conjoiners has left Warren with only one eye, having lost the other and sustaining other severe injuries in combat with the Conjoiners and with the robotic worms on Phobos. Their differing experiences of the war lead Nevil and Warren to fall into a dispute just as Nevil is about to make a diplomatic visit to the Conjoiner headquarters. Warren later fabricates evidence that Nevil was massacred by the Conjoiners upon his arrival, as an excuse to resume hostilities, at which point Nevil loses what remaining attachment he had to Warren. Warren is last seen secure in his position among the Coalition leadership.

Felka

Felka is the product of an experiment carried out by Galliana on Mars during the early days of the Conjoined, by which nanobots were interfaced with Felka constantly beginning early in her embryonic development. She develops into somewhat of an autistic savant, incapable of distinguishing human faces or any normal social interaction, though she has an advanced intellectual capacity, even among the Conjoiners. She spends much of her youth single-handedly operating and keeping alive the Great Wall of Mars, a massive robotic terraforming entity designed by Sandra Voi and critically damaged in the Coalition-Conjoiner War. Felka is rescued by Clavain in the evacuation of the Conjoiners' nest on Mars, shortly before the Conjoiners become the first living humans to depart the Solar System, aboard a starcraft clandestinely manufactured inside of Phobos.

Felka later forms one of her closest friendships on the first extrasolar planet the Conjoiners land on, Diadem, with Iverson, the sole survivor of a prior colony that had been planted there from an AI starship that had raised human colonists from embryos after reaching the planet. Iverson and Felka share a common passion for studying emergent phenomena, including a low-level intelligence formed by a planet-wide network of ice-dwelling worms. Felka makes considerable progress toward a more normal capability for social interaction during her friendship with Iverson, although Clavain later find out Iverson is in fact "Setterholm", another member of the Diadem colony who killed all the others. Setterholm attacks Clavain so Clavain kills him.

Centuries later, Felka lives in the Conjoiner mothernest, still pursuing experiments in emergent phenomena, when she departs from the infiltrated Conjoiners with Clavain. She eventually ends up on the colony on the planet Ararat and is 'taken' by the Pattern Jugglers there, presumably absorbed by them. Clavain's last requests after the final Skade encounter, which results in his death, suggests that Clavain's 'funeral', which resulted in his body being dumped into the Pattern Juggler mass, was observed by two women, one older, one younger, appearing from the mass of Juggler growth. Although if Clavain was ever absorbed into the Juggler Matrix was left unsaid.

Galiana

Galiana was one of the most prominent founding members of the Conjoiners, a group that began on Mars and became linked with each other in a partial transhumanist collective consciousness through experimenting with interfacing their brains with nanotechnology and AI components. Galiana captured Nevil Clavain during the Conjoiner-Coalition war and held him captive on Mars for several months, but rather than the harsh treatment Nevil expects due to Coalition propaganda, Galiana attempts to befriend him and convince him of the Conjoiners' merits. Galiana later leaves on an interstellar exploration mission where she encounters inhibitor machinery that consumes her crew and places her under permanent mind control.

Skade captures Galiana's Reefer Casket in an attempt at ransom but Clavain decides that destroying Skade is more important than the possibility of healing Galiana and so detonates pin-head munitions planted on Skade's ship by Scorpio. Skade escapes the explosion by placing her head in a torpedo and having it fired towards the pursuing Conjoiner fleet. It is implied at the conclusion of Redemption Ark that Galiana saved an imprint of herself in the oceans of Ararat. This version is reunited with Clavain and Felka when the Pattern Jugglers absorb them in their entirety.

Remontoire

Remontoire is one of the most prominent of the founding Conjoiners. He plays a leading role in the defence and evacuation of the Conjoiners' main nest on Mars when Nevil Clavain is first inducted into the Conjoined. A century later, in 2303, he assists Irravel Veda in the repair of her ship Hirondelle, after her encounter with Captain Run Seven. He is then betrayed by her and becomes the prisoner of Run Seven. He becomes the object of Run Sevens' sadism until he is rescued by the Conjoiners. Centuries later, he, Clavain, and Skade work together among the top leadership of the Conjoiners. After Clavain leaves the Conjoiners, Remontoire also ends up following him and turning against Skade. Remontoire was responsible for originally capturing Scorpio, who tried to kill him then, but would eventually work closely with him. When Remontoire learns that Clavain has been killed, he pauses and focuses all his thoughts on mourning Clavain for a full ten seconds, which is seen as a profound act of devotion for a Conjoiner, (Although later, he says to Scorpio that he hasn't done truly grieving yet). Another Conjoiner, Weather, who belongs to another faction that has been out of contact with Clavain and Remontoire for centuries, reveres Remontoire as the greatest leader of the early Conjoiners.

Remontoire's last action in Absolution Gap is to try to draw an Inhibitor swarm away from Nostalgia for Infinity. The outcome of this engagement is not shown, but the leaders of the Infinity crew consider him unlikely to survive after his last transmission, although his final status is ultimately left unknown.

In the short story "Galactic North", it is revealed that Remontoire's experiences were merged into the Conjoiner collective memory at some point in time. They are kept preserved for thousands of years, and at one point used create a likeness of him to negotiate with Irravel Veda, whom he met with in Galactic North.

Remontoire's name, like that of the Conjoiner Clepsydra in The Prefect, is a term from horology.

Scorpio

Scorpio, a Pig, is an ex-crime lord from Chasm City. His earliest memories indicate that he was once part of the crew aboard a pleasure craft. When the craft was attacked by a passing lighthugger, he found himself, and fellow crew-pigs, used as game in a sadistic hunt by the human invaders. Being the only pig to survive, and with the revelation that, even while as crew aboard the space-yacht, he was a slave to human masters, Scorpio develops an intense hatred of humankind which drives his rise to infamy, becoming a feared figure in the Rust Belt. Although not described in detail, it appears that he is eventually captured and detained by the Demarchist authorities, being transported to likely execution.

He was found captive on a Demarchist vessel Clavain attacks at the beginning of Redemption Ark. After Clavains' defection, Scorpio and Remontoire head to a Habitat orbiting Yellowstone in order to stop Clavain. After a long chase, Scorpio becomes part of the rescue party sent to Resurgam system to save everyone on the planet from the Inhibitor machine.

On Ararat, Scorpio becomes the leader of the settlement after Clavain goes off to consult his losses. After Remontoire and the rest of the Conjoiners arrive in system, Scorpio heads to the island to consult Clavain. After they arrive on Skades' iceberg, Scorpio is forced to kill Clavain in order to save Aura.

Scorpio and those that were on the Nostalgia for Infinity when it left Ararat travel to Yellowstone, only to see it utterly destroyed by the Inhibitors, then head to Hela in order to find Quaiche and negotiate with the shadows. In a twist of plans, Scorpio, Khouri, Vasko and Aura, after Scorpio destroy the bridge crossing Absolution Gap, decide to let the Scrimshaw Suit carrying the shadow envoy fall to its destruction with Quaiche's cathedral. His fate after this is unknown (all that is said is that "after that, he didn't remember very much"), although it is implied that he is the one accompanying Aura on planet Ararat in the prologue and epilogue of Absolution Gap. This would, however, make Scorpio over four hundred subjective years old by Yellowstone's calendar though he has only lived through 60 or so due to relativistic effects and prolonged time in 'reefer' (cryo) sleep. He had previously stated he would be unlikely to reach a body age beyond his 50's, but how much of this predicted life expectancy was due to his biology and how much to his dangerous lifestyle is unclear as few other hyper-pigs are major characters.

Scorpio's pig biology leaves him at a disadvantage here in space travel as it becomes clear the repeated freeze/thaw of reefer sleep is taking an enormous toll on him and shortening his life. It is implied that Scorpio may not survive another freezing. Humans such as the Conjoiner characters and even baseline (unaugmented) humans are far more resistant to the affects of reefer sleep.

In the epilogue of Absolution Gap, it is strongly implied that Scorpio indeed lived way beyond his expected lifespan. Hundreds of years after the events on Hela, Aura vists Ararat with a "stout guardian protector" who is implied to be Scorpio.

Absolution Gap

Aura

The daughter of Ana Khouri and a renegade from Resurgam named Thorn, Aura is altered in utero in the Hades matrix to convey knowledge of advanced technologies in order to fight the Inhibitors. She is also adapted with Conjoiner technology. At one point, Skade kidnaps her and becomes her surrogate mother: she is "born" when she is cut from the dying Skade (which Skade allows in exchange for Nevil Clavain's death). She later falsifies her own memories and assumes the name Rashmika Els to gather intelligence on Hela. In the prologue and epilogue of the book (roughly 400 years after the Hela mission), she has returned to Ararat as the Greenfly machines are consuming the galaxy. She decides to head to the Pleiades star cluster, which other humans have already retreated to (this colony later features in "Galactic North").

Rashmika Els

Rashmika is the assumed name that Aura takes as she covertly inserts herself into Quaicheist society in a bid to gain access to Quaiche himself and thus the mysterious Shadows. Rashmika is unaware of this for most of the story, as she has also manipulated her own (Aura's) memories. Instead, she believes she is on a quest to find her missing "brother" that happens to take her to the Cathedrals of the Permanent Way. Rashmika is imbued with the unusual ability to know with 100% certainty (and seeming success rate) when someone is lying. This enables her to become useful to Quaiche. She originally believes that humanity should negotiate with the Shadows, a race that claims to exist in a parallel brane world to ours, but Scorpio convinces her otherwise by when he discovers that this caused the last race to do so to be wiped out. At the end of the novel, Rashmika's shell of false memories begins to break down, and she remembers her previous identity as Aura.

Quaiche

Quaiche was taken on board the Lighthugger Gnostic Ascension by Queen Jasmina in order to scout solar systems they encountered. During the exploration of Hela, the moon of a gas giant called Haldora, Quaiche's shuttle is destroyed and his love, Morwenna, is killed when his autopiloted exploration ship accelerates too quickly in order to rescue him. Incidentally, the Gnostic Ascension is also destroyed when it returns to the system.

The combination of this near death experience, and the detection that the gas giant planet Haldora disappears intermittently for a fraction of a second, cause Quaiche to succumb to an indoctrinal virus. As a consequence, over the following decades, a multitude of churches are established on Hela, each centred on a mobile Cathedral that constantly moves around Hela, keeping the enigmatic Haldora in view.

During the time on Hela, Quaiche acquires a digital envoy from the Shadows, a mysterious race that tries to communicate with our universe through Haldora. The question of contact with the Shadows is a major element in the novel Absolution Gap.

Constantly fearful of losing sight of Haldora, Quaiche concocts a plan to stop Hela's rotation using a lighthugger's engines. The lighthugger he attempts to capture for this plan is the Nostalgia for Infinity, the crew of which are able to repel his assault and take over the Lady Morwenna. In the aftermath of the fight, Quaiche is killed while trying to escape the cathedral.

Grelier

Grelier was originally employed on the lighthugger Gnostic Ascension by Queen Jasmina, the captain. His job as surgeon-general seemed to involve constantly cloning the extremely masochistic Queen new bodies so she could repeatedly torture herself to death. He also used some of the bodies himself; Quaiche discovers that he is a paedophile, that he carried out various immoral acts on them before they were fully grown and then claimed that they had not developed properly. Quaiche eventually uses this to blackmail him into helping him overthrow Jasmina. He is then employed by Quaiche to generate indoctrinal viruses to maintain his and others' religious feelings. When the Nostalgia for Infinity arrives on Hela, Grelier attempts to hold Aura hostage, prompting John Brannigan to kill him with a hypometric weapon, removing parts of him from space-time.

The Prefect

The Clockmaker

A robot originally created by SIAM (or Sylveste Institute for Artificial Mentation) to study the Shrouder technology, it incorporates an Alpha Level Simulation of Philip Lascaille, the first man to return from a Shroud alive. After being sent into a shroud (again), it returned a docile entity that did little but (as its name implies) make intricate clocks until going berserk at SIAM killing or maiming numerous people before Panoply stopped it. Having absorbed Shrouder technology, conventional human weaponry has little effect on it; an extremely strong EMP can disable it for a little while and it can be contained in a extremely strong magnetic field. Because of Lascaille being murdered (involuntary destroyed by the alpha simulation creation process) and the Shrouder visits, it developed a great hatred against SIAM and Panoply and expressed it with complexly cruel mechanisms (including attacking the Head Prefect with a scarab, a device that would kill her if she fell asleep and could not be removed). Tom Dreyfus promised to investigate Lascaille's murder in exchange for Clockmaker's help against Aurora, the antagonist of the novel.

Tom Dreyfus

Tom Dreyfus is a Prefect (and later a Senior Prefect), an agent with an elite investigative police force around the Glitter Band known as the Panoply. He is heavily involved in The Clockmaker "incident". He is the central character of The Prefect

He was deeply affected by the loss of his wife, during this incident, and so had his own memories of the events erased. He was also a great friend of the Supreme Prefect at the time, Jane Aumonier.

Diamond Dogs, Turquoise Days

Dr. Trintignant

Dr. Trintignant is a one of the main characters in Diamond Dogs, Turquoise Days. He also makes a re-appearance in the short story "Grafenwalder's Bestiary". Although little is known of his personal background, Trintignant is revealed to be an overzealous cyberneticist who worked with Calvin Sylveste on the "Eighty" project. His ambition becomes obsession, but he was forced to abandon the project when test subjects became scarce. In order to pursue his thirst for knowledge, he experiments on himself, changing his physical body drastically.

In Diamond Dogs, Trintignant is hired by Roland Childe to go on an expedition to visit a mysterious alien structure known as the Blood Spire. Trintignant transforms Childe and Richard Swift into sleek-looking mechanical dogs, or "diamond dogs". When Swift comes back from the Spire to change back into his original form, he discovers that Trintignant has "committed suicide", by dismantling himself with his own surgical machinery. Trintignant proclaims what he did to Childe and Swift is his magnum opus, and he would rather die than take them apart.

However, in the short story "Grafenwalder's Bestiary", Trintignant is retrieved by the former Denizen, Ursula Goodglass, who electronically reconnects his body parts, but apparently does not reassemble his body. Her husband, Edric Goodglass, is revealed to be Trintignant himself at the end of the story, and it is hinted that Trintignant has turned Grafenwalder into one of his test subjects.
