Liaden universe

The Liaden universe (/liːˈeɪdɛn/ lee-AY-den or /liːˈeɪdən/) is the setting for an ongoing series of science fiction stories written by Sharon Lee and Steve Miller. The series blends elements of space opera with romance, intrigue and wizardry.

As of July 2024, the series comprises 25 novels and 33 chapbooks, also published in ebook format.

Setting

The Liaden universe is a multi-universe setting that spans several millennia, with a central focus on Clan Korval, a prominent house in Liaden society known for its telepathic abilities and military capabilities. The universe is set in a far-future era, within a galaxy undergoing decrystallization, which was once home to humanity. Humanity's diaspora is categorized into three primary sub-races: Terran, Liaden, and Yxtrang.

Key Elements of the Liaden Universe

• Clan Korval: A powerful and influential Liaden clan, known for its telepathic abilities and military prowess.
• Liaden Society: A complex society with a strong military tradition and a unique caste system.
• Decrystallizing Galaxy: The setting for the series, a galaxy undergoing a mysterious process of change.
• Human Diaspora: The human race is divided into three primary sub-races: Terran, Liaden, and Yxtrang.
• Telepathy: A common ability among Liaden, used for communication, combat, and other purposes.

Primary Themes

• Family and Loyalty: The bonds of family and clan are central to the series, with characters often making sacrifices for the good of their loved ones.
• Military Strategy and Tactics: The Liaden military is a major focus of the series, with complex battles and strategic maneuvers.
• Moral Ambiguity: Characters often face difficult choices, blurring the lines between good and evil.
• Exploration and Discovery: The Liaden Universe is vast, with many planets and civilizations to explore.

The series portrays diverse alien cultures and advanced technology, often exploring themes of political intrigue as characters navigate the power dynamics of the Liaden Empire and engage with various alien factions. It also features interstellar exploration, with characters traveling to distant worlds, encountering new cultures, and confronting unknown challenges.

Series overview

1988 saw the publication of the first two books in the seven-book "Agent of Change" sequence. These books follow the conflict between Clan Korval, a prominent Liaden clan, and the mysterious "Department of the Interior." Despite the destruction of the department's headquarters on Liad at the end of the original sequence, the department's remnants continue to influence Clan Korval in subsequent novels.

The eighth novel, Balance of Trade, takes place 275 years prior to the conclusion of the "Agent of Change" sequence. The novel introduces Jethri Gobelyn, a young Terran trader, to a Liaden master trader, causing unrest among many. In 2013, the publication of a sequel, Trade Secret, chronicled Jethri's journey as a trader. May 2022 saw the publication of the third book in the series, Fair Trade.

Published in February 2005, the ninth novel, Crystal Soldier, takes place earlier in the timeline. It is the first half of The Great Migration Duology and tells the story of Cantra yos'Phelium, who piloted the original exodus to Liad, and her partner M Jela. In 2006, the story continued with the publication of a sequel, Crystal Dragon, which focused on the founding of Liad and Clan Korval.

Publication history

After writing the first three books (Agent of Change, Conflict of Honors, and Carpe Diem, published in 1988–1989), the authors were informed that sales were insufficient to justify continuing the series. However, the books developed a following on the Usenet group rec.arts.sf.written, where they were added to the group's FAQ.

Upon gaining Internet access, the authors discovered a significant reader base eager for the next installment, which was anticipated to be titled Plan B. In response, they published several chapbooks and began writing Plan B (released in 1999), followed by three more books to complete the Agent of Change sequence. Additionally, the authors wrote numerous short stories, some filling gaps between novels and others providing background on various characters.

The first three novels were initially published in mass-market editions by Del Rey. They were later re-published by the now-defunct Meisha Merlin, which also anthologized the earlier books. Subsequently, the novels were re-issued in mass-market format by Ace Books. Some of the earlier works and stories were made available as e-books through Embiid Publishing, which is no longer in business.

In 2007, Baen Books began publishing the first ten Liaden novels in electronic form, followed by two short story collections. Baen continued with new Liaden novels starting in 2009 and began releasing the first ten novels in omnibus trade paperback editions in 2010.

As of 2022, the series remains ongoing with twenty-three novels, numerous chapbooks, and short stories. Several additional novels are contracted for future publication. All of the novels are available as e-books.

Factions

In addition to members of the three main divisions of the human race Terran, Liaden, and Yxtrang, there are members of non-human races that are featured, such as Clutch Turtles, Cats, Norbears, and Ssussdriads.

Liaden

Home planet "Liad". Liadens are usually shorter than the Terran norm, often with golden skin. They are deeply concerned with their melant'i which roughly corresponds to the concern with "face" for which Japanese samurai are famous. Some are almost rabidly isolationist; it is not uncommon for bigoted Liaden to refer to those of other races as "it", likening them to animals. Several characters are part- or even half-Terran: this does not endear them to the isolationists.

Liaden society is clan-based, each Clan being made up of one or more families ("lines"). The Head of a Clan is the "Delm", the head of a line is the "Thodelm"; either might be male or female as circumstances dictate.

Liaden Clans do not generally allow lifemating. Instead, Liadens practice contract marriages, where two individuals from different clans are ordered, or allowed, by their Delms to create a progeny for one of the two clans. This marriage is over when the terms of the contract are fulfilled. Most members of the clan must produce at least one progeny to replace them.

Lifemating is when two individuals become exclusively bound to one and other. This can happen rarely by order of a Delm, or this can happen by the physical, emotional, and spiritual bonding of two individuals with dramliza abilities (regardless of the depth of those abilities).

Some Liaden are trained as explorers: the Scouts. They are regarded with distaste by the more isolationist within Liaden society.

Most of the stories thus far center on members of Clan Korval, made up of the yos'Phelium and yos'Galan lines. Scouts also appear often.

Terran

Home planet known as "Terra". As remarked above, there is a brief reference to the possibility that this planet is possibly the fourth of that name. Possibly one prior Terra would have been destroyed along with the war-torn universe/galaxy from which mankind fled in Crystal Dragon, though neither the word Terra, nor Terran appear in that book. From cultural references, familiar English names, and references to regional linguistic dialects that appear in the core books, it seems likely that this Terra is nonetheless our own Earth. There appears to be some resentment that the "younger" races (usually Liaden) hold more power in the realm of shipping and commerce than Terra; there is reference to at least one political party involved in less-than-legal operations. Based on the description of the Liaden as younger races, it may be reasonable to assume that they predated the Liaden arrival in the expanding universe. Whether they simply arrived sooner and separately from Cantra's convoy or whether Terra existed in the expanded universe separately from the "Predecessor" universe is unclear.

The Juntavas are an organized-crime "clan" who appear in various guises, sometimes as antagonists, sometimes as allies of the main characters. Unlike the real-world mafia, the Juntavas are apparently able to act as an unopposed organized government in their own right, to the point of having appointed officials called Sector Judges who administer justice within their appointed jurisdictions. The Juntavas are usually not as oppressive as they might be, because they have learned that too much of that sort of thing is "bad for business."

A number of other planets are known to have non-Liaden human inhabitants, presumably of the Terran strain. Some of these worlds, such as Surebleak and Delgado, were settled by Terrans from this universe's Terra. Others, such as Sintia, were settled by ships from the same Crystal Dragon-era colonization waves as Liad and Terra.

Some of these colony worlds, such as Vandar, have backslid to pre-spaceflight technology levels. These worlds have been considered interdicted by the Liaden Scout Corps, with external contact forbidden in order to permit their societies to develop without interference. As of "Prodigal Son", post–I Dare, there are signs that this policy may be changing.

Korval-linked

• Theo Waitley: recently discovered (by Delm Korval and the clan generally) daughter to Daav yos'Phelium and acknowledged in Ghost Ship as blood kin to Korval but not Seen by Delm Korval so not a clan member (Daav and Val Con would probably advise Theo against membership at present).
• Kamele Waitley: Theo's mother and professor at Delgado University. Da'av was Kamele's Onagrata using the name Jen Sar Kiladi after Aelliana's murder.

Independent A.I.s

• Jeeves: planetary security A.I. repurposed as butler to yos'Galen at Trealla Fantrol, but transferred to Jelaza Kazone upon Korval's relocation to Surebleak.
• Tocohl Lorlin (Daughter of Korval): Jeeves' daughter. Currently in control of Tinsori Light.
• Bechimo: a "sentient and sapient" space ship, built long ago as a "long-loop trader", incorporating "old tech." He was rediscovered by Win Ton yo'Vala. Theo Waitley became his Captain.
• Admiral Bunter: Originally a composite AI, made up of seven semiderelict ships (with thirteen old and cramped computers between them) out of the junkyard at Jemiatha's Jumble Stop. Admiral Bunter is Theo's Fault. It guarded Jamiatha's Jumble Stop Station from pirates for a time; it was later transferred to another "cranium" and ship by Mentor Tolly Jones, Tocol Lorin, and Inkirani Yo (another mentor), and has since become a "Free Ship," no longer associated with Jamiatha's Jumble Stop.
• Disian: A "Free ship" mentored by Tolly Jones.

Yxtrang

Home planet unknown at this time. Usually much larger than the Terran norm, they are a war-like people who live for conquest. They are almost universally prone to thinking of the other human races as animals.

References in Crystal Soldier and Crystal Dragon suggest that the Yxtrang are the descendants of a group of "X Strain" and "Y Strain" genetically engineered soldiers who served in a platoon with Jela and accompanied the human migration to the new universe. Some of them venerate Jela (an "M Strain") for his skills and deeds as a warrior.

It is not known whether they can interbreed with Liadens or Terrans, though given their common genetic origin there is no reason why they should not be able to; the likely lifespan of such offspring is short, not for merely biological reasons.

• Nelirikk: ex-Explorer (equivalent to Scout), subsequently sworn to Line yos'Phelium, becomes Miri's bodyguard; aka "Beautiful".
• Hazenthull Explorer: junior Explorer, subsequently sworn to Line yos'Phelium.
• Diglon Rifle: enlisted soldier attached to Hazenthull, subsequently sworn to Line yos'Phelium.
• Commander Vepal: Yxtrang roving ambassador.
  • Pilot Erthax: member of Vepal's Small Troop.
  • Ochin Rifle: member of Vepal's Small Troop.

Clutch Turtles

These non-humans are even larger than Yxtrang and very long-lived; they appear much like turtles walking upright, hence the name. The length of their names are directly proportional to how old they are and their accomplishments: Edger's full name apparently takes some hours to recite. They are usually slow to act, but are very dangerous when angered and can move quickly when needed.

Clutch turtles travel in starships made from hollowed-out asteroids using an electron substitution drive that can have hallucinogenic effects on the human nervous system. Both a 'low drive' and 'high drive' exist; usually the clutch turtles use the slower low drive, but used the considerably faster high drive in "I Dare."

Clutch turtles are able to command forces of great destructive or healing potential by singing. Clutch turtles are greatly feared and avoided by the Yxtrang as the result of a resounding defeat in battle many years prior to the timeframe of the story.

The Clutch turtles encountered in the "Agent of Change" sequence make up a "market research" team on behalf of their clan, who are known for manufacturing crystalline blades of extreme sharpness and durability by growing them in caves over a timespan of decades.

• Edger
• Sheather
• Watcher
• Selector
• Handler

Cats

There are many cats which appear in the stories, usually by name, often taking an active part in the proceedings. Unlike ordinary housecats, these cats often display paranormal abilities, as well as considerable intelligence.

• Flinx: at Tarnia's Clanhouse
• Lord Merlin: Anthora's cat, very active in I Dare
• Patch: Binjali Repair Shop's resident cat and "co-owner"
• Lady Dignity: Daav yos'Phelium's answer to his sister's complaint that he has no (dignity, that is)
• Relchin: An orange-and-white cat who "enjoys the outdoors" also resides with Daav yos'Phelium
• Silk: Pat Rin's mouser and majordomo on Surebleak
• Charzi: lives in the Lysta Clanhouse in "Misfits"
• Coyster: Jen Sar Kiladi's cat, attached to Theo Waitley on Delgado in Fledgling
• Mandrin: Jen Sar Kiladi's black and white on Delgado

Norbears

Norbear—Size: 16–22 cm; Weight: 121–180 g. Furred quadrupedal herbivorous mammal with a burrowing habit possessing a soft dense coat, ranging in color from grey, brown, black, orange, white, or mixed. It has a fearless and lively disposition, and is a natural empath. Adapts well to domestication, but is banned on certain worlds.

• Master Frodo aboard the Dutiful Passage in Conflict of Honors.
• Hevelin (named after long-time science fiction fan Rusty Hevelin)
• Podesta: Hevelin's great-granddaughter

Trees (Ssussdriads)

The race formally known as Ssussdriads. An unusual character is Jelaza Kazone (a term that has been translated as "Jela's Promise," "Jela's Contract," or "Jela's Dream," among other variants) and the seedlings thereof (of which only two have thus far appeared in narrative). This very large tree lives in the grounds of Clan Korval's primary residence (also called Jelaza Kazone) and is in the habit of communicating its likes and dislikes to senior members of that clan; it has particularly been noted to have an interest in the likely parents of future children of the Clan.

As a young soldier, Jela found the tree on a desert planet on which his ship had crashed. Though barely a stunted seedling and the last member of a dying race, the tree was by itself able to repel invasion of the planet by the enemy Sheriekas. As an act of trust, the tree gave its only seed pod to feed the starving Jela. When Jela's rescue came, he refused to leave the tree behind.

The tree proved to be intelligent, and able to communicate via mental images. It also had the ability to manipulate the chemistry of its seed pods to create useful pharmaceutical compounds. Both these powers proved useful as Jela and Cantra searched for information necessary for mankind to escape its collapsing universe.

The name Jelaza Kazone refers to the promise Cantra yos'Phelium made to Jela, who knew he was destined to die before the migration could be complete, to see the tree through to safety on the new human homeworld. Clan Korval holds itself the guardian of this promise in perpetuity, and every trading vessel of Korval carries a seed of the tree somewhere on board, to ensure the survival of its race.

• Tree mentioned in Plan B at Erob's Clan house on Lytaxin.
• Seedling was installed on Cantra's ship at the end of Crystal Dragon. This sapling was recovered, alive, in Neogenesis.
• Sapling planted on Yulie Sharper's freeholding.
• Two saplings planted on yos'Galan's island on SureBleak.

Concepts

Melant'i

A great deal of the Liaden culture centers on melant'i. Part of this concept is roughly analogous to personal honor or good manners: a person of impeccable melant'i will behave in a certain way, in a given situation. It is also used to distinguish between a person's different roles in life. If one is speaking to a shipmate in one's role as an officer of the ship, one uses a particular mode to cue the shipmate as to the formality of the situation, and is said to be expressing one's melant'i as that officer. If, on the other hand, one is speaking to the same shipmate, but in the role of daughter, one uses a different mode and is expressing the melant'i as a family member. Different levels of formality, and actions, will be appropriate in each case.

Bows and modes of speech

High and Low Liaden

The High Liaden language is used for all formal conversations between people, reflecting the exact melant'i and roles of the two individuals. For example, a sentence might be in the role of Master Pilot to Student Pilot, while another sentence might be Parent to Child, or Adult to Adult, or Adult to Your Delm (your clan leader), or Adult to Another Delm (some else's clan leader). The forms are symmetrical and directional, with Master Pilot to Student Pilot being a different mode than Student Pilot to Master Pilot. With High Liaden, you can always tell the roles that the speaker intends for the listener to interpret what is being said.

Low Liaden is reserved for informal family conversations.

Liaden bows

Bows are used by Liadens when both meeting and parting, and also reflect the exact melant'i and roles of the two individuals. Bows are precise and complicated.

Space travel

Jump drive

Human ships are able to travel quickly between planets by "jumping"; different technologies exist but are all fairly quick; journey durations are comparable to swift sea-travel here on Earth. Only the Clutch Turtles use a different method, with predictably idiosyncratic side-effects (of which few details are available).

Propulsion and artificial gravity is provided by Struven Surface Units which Theo describes as having a "sense of presence." The sealed unit is the source of gravity that the ship generates and "the source of the Struven Surface that the engines then amplified and tuned, building fields that allow the ship to interact with the lattice crystal of space-time and to move...elsewhere."

From The Gathering Edge:

A ship in the Jump configuration preferred by most starfaring groups neither comes nor goes. If the Jump is not calculated properly, the ship stays where it is within the frame of previous motions. If the Jump is calculated exactly, the ship's energy and contents become one, contracting dimensionally, and the ship and its force packet vibrate their way into a crystalline state that adjusts space around it. The goal is to achieve an energy level meant to match that of a "place"—a star system, a nebula, a rendezvous point—where the matched energy levels permit the ship to reappear in normal space. Transferring from place to place in this way requires minimal energy once the Struven units stress the base ship-and-energy packet into a unit; space rearranges itself around the packet until the ship emerges—or occasionally fails to emerge—at the target location.

Ships

Ships range from single-person courier, small trade craft, private ships, long-loop, and family trade ships (depreciated in modern shipping) to large trade ships (often carrying a Master Trader), bulk cargo ships, and large passenger liners. There are of course many specialty craft for station maintenance, and other utilitarian functions. In this era of relative peace, there is little mention of purpose-built military ships, except for the battleships of the warlike Yxtrang (though mercenary companies have troop ships and various support ships). Planetary governments may have small fleets of fighter craft, for defensive purposes, that operate both in air and near space. It is not uncommon, however, for merchant ships to carry weaponry to defend themselves from pirates and brigands. Some large trade ships, such as Korval's Dutiful Passage, have incorporated enough weaponry to be considered full battleships.

Pilots and piloting

Pilots are shown deference in the Liaden Universe, both in Terran and Liaden space. This is due to respect and/or fear of the pilots' capabilities and their importance to the lifeblood of trade and commerce for planetary society. Pilots are addressed as "Pilot" as an honorific title.

Pilots must have superior reflexes, coordination, and spatial orientation. Pilots need proficiency in higher mathematics to be able to quickly and accurately solve equations in trajectory, orbital mechanics, and jump coordinates (to many decimal places); one does not place one's life and one's crew or passengers in peril should computer navigation fail. A pilot needs to be able to defend herself in the low port or away from civilization, thus trains in self-defense and personal weaponry.

The Pilot is responsible for the ship and passengers; the Co-pilot is responsible for the pilot and ship. (Bechimo adds, "the ship is responsible for pilot and crew.") The pilot/captain operates the ship from the primary control board—"sits First". The co-pilot, or acting co-pilot, "sits Second". Larger ships may have a third board, communications officer, executive officer, etc.

Many, if not most, pilots belong to the Pilots Guild. The Guild takes 3% of the pilot's income for life and in return provides many important services. These services include certification (required on many ships and lines), legal services and bail bonds, mailboxes with forwarding, hiring and personnel services and records, and in larger localities a Guild Hall with lounges, bars and/or cafes. Each Guild Hall has a Guild Master.

The Guild certified Pilot Classes:

• 3rd Class: base level, qualified to work within system and orbit, operating ships not above Class B.
• 2nd Class: mid-level, qualified to lift any ship to Class AA within system and orbit.
• 1st Class: a.k.a., Jump Pilot, qualified to fly interplanetary space via Jump hyperspace technology.
• Master: one able to perform all aspects of piloting with excellence. This grade may undertake to train and test any of the lower three levels.

First Class Jump Pilots are awarded and wear a Pilot's leather jacket. This heavy-duty garment, with many internal pockets, is both a sign of rank and protection against weather and misadventure. Only Jump Pilots wear a Pilot's Jacket; this is not by law, but tends to be enforced through "social pressure" which may become physical.

In I Dare, Pat Rin is given a rating of "1st Class S," S for "small," until the pilot has enough flight time logged on the larger ships.

Master Pilots may train and certify pilots. All Liaden Scout Pilots are of Master Class. A pilot in training will be granted "provisional" status in grade as the student advances.

Fan fiction

Lee and Miller strongly oppose any fan fiction written in the Liaden universe. "We built our universes, and our characters; they are our intellectual property; and they are not toys lying about some virtual sandbox for other kids to pick up and modify at their whim. Steve and I do not sanction fanfic written in our universes; any such work that exists, exists without our permission, and certainly without our support."
