Chapter Summary

A periodic ten‑day observance when gates open and limited movement between the maths and the extramuros is permitted. It is the standard season for Collection and graduations and culminates in a public handover at the communal supper, when the highest‑ranking outside official formally transfers foundlings and newcomers into mathic jurisdiction with oaths and a bell.

The great stone-vaulted complex at the heart of the math, built around the Praesidium and its clock. It hosts rites (including Voco), manages gate openings during Apert, and provides access to bells and the rooftop starhenge.

Warden Regulant at the Concent of Saunt Edhar, remembered for strict inward oversight including a period when rooftop access to the starhenge was sealed. During a later mass Voco she briefed and dispatched Evoked avout toward the Concent of Saunt Tredegarh—newly designated to host a Convox—issuing guidance for discreet travel under possible surveillance.

An in-world reference work that compiles numbered senses and usage notes across forms of Orth. The cited 4th edition (A.R. 3000) also records brief historical notes and editorial guidance on certain terms.

A rooftop complex of megaliths and instruments atop the Præsidium, mechanically coupled to the Mynster’s great clock. It houses telescopes, a noon synchronizer that admits sunlight by prism, and ancillary workspaces.

A walled precinct within the Concent of Saunt Edhar that houses the Decenarians (Tenners) and their Edharian chapter. It centers on the great clock and rites in the Mynster; members may be Evoked through the Voco aut by the Sæcular Power.

A named historical period referenced in mathic accounts and The Dictionary. Descriptions align it with an industrial era of cheap steel and rail‑borne heat engines and place it before the Reconstitution.

A communal dining hall and kitchen within a math, reached from the Cloister's covered walkway. It serves daily meals for avout and, thanks to its acoustics and climate, is a favored place for aging casks.

An avout nicknamed Barb, son of Quin, first entered Saunt Edhar as an extramuros visitor with a knack for mechanisms and was later Collected. He studies orbits with peers and, after a later multi‑name Voco, is among those instructed to travel to the Concent of Saunt Tredegarh.

A revered mythic figure associated with the dawning of Light and, in legend, a moment of upsight by a river; named as father of Hylaea and Deät. He is invoked in mathic liturgy and represented by a renowned statue in the Hylaean Way; later traditions diverge between Hylaean and Deolater readings of his vision.

An ivy-snarled ruin near the page-tree coppice by the Concent of Saunt Edhar, between the Decade and Century gates. Refitted within as a quiet retreat, it has also served as a popular shared workspace, with a light-tight sub-cellar used for discreet study; its sub-basement is noted for profound quiet.

Statho is the Primate who presides over rites in the Mynster, coordinating with wardens and, when present, the Inquisition. He has officiated Eliger, Voco, and an aut of Anathem; in a late‑night Voco he read from a list to Evoke a large group, culminating in the call of Fraa Jad of the Millenarians.

A mathic order named for Saunt Edhar; at the Concent of Saunt Edhar its Thousanders are identified with the order and its tradition includes large‑scale praxic works on the crag and Mynster. Recently, Edharian avout organized theoric work concerning an orbital visitor, and several were Evoked toward a Convox at the Concent of Saunt Tredegarh.

A revered Saunt of the mathic tradition and namesake of both the Concent of Saunt Edhar and the Edharian Order. In current accounts he is referenced through the concent’s praxic tradition and by the order that bears his name, not through direct biography.

An order within the mathic community at the Concent of Saunt Edhar, commonly called the New Circle and led locally by a First Among Equals. Members are recruited during Eliger; in current accounts, a Decenarian member is named during a Voco.

A long, rectangular cloth worn by avout as part of their everyday habit, managed with a waist chord for hooding and modesty. Bolts are made in small quantities from newmatter within the maths and have unusual properties: they stretch to admit bullets but can be cut by sharp arrows.

Also called the Centenarian Gate, a clock-controlled, water-driven portal of the concent that operates on a hundred-year cycle. It parallels the Year and Decade gates and is associated with the Centenarians’ rare Apert.

A simple cord worn by avout around the waist to secure and adjust the bolt; it is also used to tie and carry a rolled bolt when slung over the shoulder. Commonly cited as one of the three personal items along with the bolt and the sphere.

An extramuros religious community identified as followers of Deät; their worship spaces are called "arks." Avout use them as a familiar comparator for nave layout and congregational behavior, and Deolater pilgrims have been seen leaving offerings at Deät’s pedestal during Apert.

An office within a math responsible for the outward watch from the Mynster's rooftop aerie; it directs sentinels and coordinates external security. It also controls access to the upper works, including closures of the portcullis and supervised routes from the Fendant court, such as the ladder approach to the carillon.

A roofed gallery encircling a rectangular garden at the heart of a math, serving as a quiet, contemplative space and a thoroughfare connecting key buildings. The term’s meaning in Orth has varied historically; here it refers to the central courtyard and surrounding walkway within the math.

An oversight body within the mathic world whose Inquisitors—and the Warden Regulant branch—enforce the Discipline and keep standards uniform across concents. It reports to the Primate, hears appeals in serious penance cases, and in defined cases can depose a Primate.

A clock-driven gate in the concent's outer fortifications that opens every ten years during the decennial Apert. It is associated with the Decenarian community and is actuated by the great clock through water-powered works routed from the pond outside the Day Gate.

A dark, glassy imaging tablet used with rooftop instruments to record and replay night-sky observations across time. It embeds a syntactic device that supports pan/zoom, scrubbing, and self-illuminated playback; analysts can also integrate spans of time into still images. Its use is tolerated within the Discipline as a grandfathered praxis.

A personal, size‑adjustable ball used by avout within a math as part of a minimal kit; made of newmatter and known to stretch and absorb impacts. It can be shrunk to palm size by tracing counterclockwise circles on its surface.

A young Tenner avout at the Concent of Saunt Edhar, practical and quietly attentive. She works closely with Suur Ala on bell and observing tasks; after a multi‑name Voco, she was Evoked and instructed to travel to the Concent of Saunt Tredegarh.

A crag‑top math east of the Mynster, home to the Thousanders, linked to the hall by a covered, hand‑carved stair. It was recently bathed in a narrow red light from the sky, and its residents raised smoke to make the beam’s path visible.

A.R. is a calendar-era notation used to count years since the Reconstitution, appearing in citations and institutional records (for example, on the Fourth Edition of The Dictionary as “A.R. 3000”). In-text phrasing such as “anno … of the Reconstitution” indicates its reference point, though the exact spelled-out expansion of the initials has not been given.

An official written record kept within a math for entries required by the Discipline; in plural (“the Chronicles”) the term also denotes the concent’s collected historical records consulted by avout during liturgy and study. Formal liaisons and similar auts are entered in the Chronicle.

An avout who serves as Warden Fendant at the Concent of Saunt Edhar. He oversees the outward watch, is consulted on external risks around Apert, coordinates responses during the opening of the gates, and conducts pre-convocation sweeps to clear and secure upper levels.

An Inquisitor visiting the Concent of Saunt Edhar during Apert alongside Onali. He is later present for a formal calling and departs the concent by aerocraft with the evoked fraa.

Hylaea is a mythic figure, one of the daughters of Cnoüs, invoked in mathic liturgy and teaching. Tradition associates her with the Hylaean Way and with interpreting Cnoüs’s vision as an insight into pure theorics; she is also the namesake of the Hylaean Anathem.

Anathem is a solemn, bell-announced rite denoting the expulsion of an avout—being Thrown Back. It is treated with gravity and is distinct from other named calls such as Eliger and Voco.

A worldwide catastrophe, poorly documented and generally ascribed to human causes, that ended the Praxic Age and led directly to the Reconstitution. Mathic sources often pair it with the Harbingers as a boundary between eras.

A figure from the classic dialogs famed for dismantling opponents' arguments and remembered as teacher of Protas; accounts hold that he was executed by the Saecular Power following a judicial proceeding.

An order within the mathic world that occupies the west nave of the Mynster and at times leads portions of Provener. The order is closely associated with the Unarian Math and the one‑year path whose residents are sometimes called One‑Offs.

A formally constituted avout chapter at the Concent of Saunt Edhar associated with the Decenarian Math. In formal rites, members may be named as being "of the Edharian chapter" for their respective math.

An Orth term denoting the world outside a math’s walls. Its nuance shifts across eras, ranging from the literal “outside the walls” to broader senses of the non‑mathic world and nearby settlements beyond a math.

An avout who serves as First Among Equals (FAE) of the Order of the New Circle at the Concent of Saunt Edhar; he has taught modern history and is remembered for saying there is "no right way to build a clock." At a Tenth Night supper during Apert he gave a brief address relating family rituals to mathic practice that pleased visitors while some avout found it glib.

A mathic order known for rigorous historical scholarship that challenges claims of novelty. Lorites often argue that purportedly new ideas have prior precedents and are associated with Saunt Lora’s Proposition about the "Last Idea."

Protas is remembered as the greatest fid (disciple) of Thelenes, credited with the doctrine that things perceived are shadows of more perfect realities in a higher world. His “Protan forms” are cited in current discussion as a shared basis for communicating theoric truths; the doctrine is later called Protism.

An Inquisitor at the Concent of Saunt Edhar during Apert. First seen incognito among visitors and later recognized in purple robes at Provener alongside her colleague Varax; during a formal Voco aut she was observed departing with Varax and an Evoked avout.

Roving officials of the Inquisition who inspect concents and enforce the Discipline. They have been observed at Saunt Edhar and dispatched to ensure compliance with orders such as closing starhenges.

An order within the mathic community, often paired in discussion with the Order of the New Circle. At the Concent of Saunt Edhar, a local chapter recruits at Eliger; though long viewed as a dwindling order, it has recently drawn several new joiners.

Sline is a Fluccish slang term derived from "baseline," used to denote ordinary people outside the maths. In current usage it commonly refers to extramuros individuals with little specialized education or outlook; a harsher, insulting sense exists but is deprecated in standard references.

An extramuros artisan interviewed by Fraa Orolo and admitted for repair work near the New Library; during Apert he visits with his son and ex‑wife and shares practical details about outside devices and conditions. His account that a colleague’s speelycaptor was blocked by the Ita for being too capable is later cited in a Regulant inquiry.

Non-mathic people who live outside the maths in the worldly realm known as the Saeculum; avout sometimes call them "extras." In mathic usage the word can also describe outside-world information that hierarchs strive to keep from avout minds.

An order within the mathic world associated by name and interpretive stance with Saunt Proc and the syntactic tradition. In avout discourse, Procians are characterized as skeptical of claims about the Hylaean Theoric World, and extramuros students who study under Procians often go on to careers in law, communications, politics, or commerce.

The final evening of Apert at the Concent of Saunt Edhar, observed as a harvest‑season festival with a communal supper and public ceremonies; it is also treated as a time when rowdiness outside the walls may briefly increase.

In Orth, "aut" denotes a formal rite by which a math or concent carries out a collective act; earlier senses refer to an individual's act. In practice it covers routine observances and rare, solemn ceremonies such as Voco.

A fertile plain remembered as the breadbasket of the Bazian Empire, associated with the flat countryside around Trantae. It is best known as the setting for the Battle of Trantae after winter crossings over the River Chontus.

A rule of thumb in the mathic tradition, attributed to Fraa Gardan, that prefers simpler hypotheses over more complex ones, likened to a steelyard balance.

An honorific within the mathic world for male avout. It is placed before a personal name and can also be used generically; the plural "fraas" refers to groups. The female counterpart is Suur.

An honorific within the mathic world for female avout. It is placed before a personal name (for example, 'Suur Trestanas') and can be used generically in the plural as 'suurs'.

A mathic community within the concent associated with the Centenarians (the Hundreders), whose opening is tied to a hundred‑year cycle. It stands adjacent to the Decenarian Math and has a reserved approach to the south nave of the Mynster.

An honorific for senior women within the mathic world, placed before a personal name (e.g., Grandsuur Tamura or Grandsuur Ylma). The "Grand-" prefix indicates elevated seniority relative to Suur, though specific criteria have not been stated.

Saunt Cartas is a revered saunt of the mathic tradition, credited with the treatise Saeculum. Early codifications cite her for forbidding all forms of liaison, and The Dictionary notes she first drew up the short list later known as the Eleven (forbidden plants).

A senior hierarch based at the Mynster who presides over major rites, may delegate portions of the liturgy, and directs access to the starhenge via the Master of the Keys. The Inquisition—including Wardens Regulant—reports to the Primate and, in defined cases, can depose a Primate.

A named high ledge within the Mynster associated with the Warden Fendant. It overhangs the upper works above the Regulant’s level and serves as a vantage over the concent; sentinels make their rounds along it, and avout who go there commonly hood themselves to avoid looking beyond the walls.

Monumental timekeeping mechanisms around which certain concents were built. Their works power gates and astronomical add‑ons; in those concents, Ita maintain syntactic‑device subsystems under strict segregation from the avout.

Senior officials within the maths who enforce the Discipline, conduct inquiries, and oversee formal rites. Their modern form arose alongside the Inquisition and includes offices such as the Warden Regulant and the Warden Fendant.

A formal term used within the maths for a high‑ranking Sæcular official; collectively, "Panjandrums" refers to such officials representing the outside Sæcular authority. Customarily, during Apert, the highest‑ranking Panjandrum present formally transfers foundlings and entrants into mathic jurisdiction.

An oversized Praxic-era reference volume on space-based weaponry consulted by Fraa Lio and peers. It includes detailed conceptual diagrams of bomb-propelled spacecraft (pusher plate with shock absorbers) used to reason about exoatmospheric propulsion and orbital maneuvers.

An elderly avout at the Concent of Saunt Edhar who serves as a doorkeeper in the Mynster around Provener. He customarily opens the chancel door after the clock is wound and tends the screen during Voco as the Evoked depart.

A large clock-driven orrery mounted just inside the Day Gate of the Mynster. It is one of the mechanisms driven by the Praesidium’s great clock, mentioned alongside lesser orreries and the Starhenge telescopes.

A Bazian general remembered for deposing the Bazian Imperator and leading legions against Sarthian forces near Trantae. Accounts state he was surrounded after pursuing a feigned retreat and died after being struck by arrows, falling on his sword.

An avout at the Concent of Saunt Edhar, noted as a theorical geologist and the FAE of the Edharian chapter. During Apert he is also introduced to speak briefly on behalf of the Edharian chapter, concluding with a remark that embraces the community’s comfort with ambiguity.

The vast vertical space behind the Præsidium’s dials in the Mynster where the great clock’s chains, gears, and escapements converge; tended by the Ita. Its lower reaches include the bells and a maintenance room, while upper works include backup mechanisms that keep the clock running during winding or rare interruptions.

A named balcony level within the Mynster at the Concent of Saunt Edhar, associated with the Warden Fendant. From here a ladder leads to a maintenance room below the carillon in the lower chronochasm, and a small reading room serves nearby avout.

A mathic sanction and resulting status: being "Thrown Back" expels an avout from a math into the Saeculum via the Anathem rite; "Throwback" is also used as a type‑label for such a person. It is invoked as a severe disciplinary measure and has been applied en masse in historical accounts.

A fixed all‑sky lens mounted on the starhenge atop the Præsidium at the Mynster. It records the entire sky to photomnemonic tablets, chiefly to capture fast tracks such as meteor trails; similar devices were installed widely when interest in asteroids surged.

Unarian Math is the one-year precinct of the Concent of Saunt Edhar, linked to the Year Gate and designed to receive visitors during Apert. It houses the Hylaean Way exhibits and a wedge-shaped memorial to those who returned during the Third Sack.

A handheld device used extramuros to capture moving‑picture recordings (often called speelies), also known to some avout as a Farspark chambre. Such devices also appear as public installations outside the walls; their use within the math is restricted and supervised.

An interior court within the Mynster at the Concent of Saunt Edhar, associated with the Warden Regulant. A parapeted inner walkway circles doorless penance cells that face the court while exterior windows look over the meadow; stairs from here lead up toward the Warden Fendant’s court.

An original library within a math that opens onto the Cloister, noted for an ancient, glass-smooth stone floor older than the New Library. It houses very old volumes and is consulted for rare technical works.

An extramuros craftsman allowed into the New Library to repair a damaged rafter before Apert. A follower of the Warden of Heaven, he later observed Provener from the Mynster’s north nave; the Ita refused permission to operate his speelycaptor from that position to avoid imaging beyond the screens.

The Periklyne is the market district of ancient Ethras that encircles the base of the city’s hill. Its center held a flat open "Plane" used for geometrical work and public dialogs.

A venerated theor cited as a touchstone for avout who seek truth in pure theorics. Later references present him as an intellectual forebear to metatheoretical work (e.g., Fraa Paphlagon) engaging the Hylaean Theoric World, while earlier work is described as rigorous action‑principle calculations in configuration spaces.

An artificial object in orbit around Arbre, observed as a blue‑white "sparker" and later as a red laser source. Based on behavior and Praxic‑Age reference designs, avout infer it is a spaceship not of local origin.

A large, unprecedented Voco in which many names were called across maths and concents. Locally at Saunt Edhar it led to multiple Evocations at once and directed the Evoked to assemble at the Concent of Saunt Tredegarh for a Convox.

An avout term for ideal theoric truths associated with Protas and the Hylaean Theoric World; invoked as a potential universal basis for communication across differing notations or media.

A physical concept invoked to explain effects that occur at very high speeds. It is used by avout to reason that a ship traveling near light speed could experience only decades while thousands of years pass on Arbre.

A venerated Saunt in the mathic tradition, known through the concent that bears his name. The Concent of Saunt Tredegarh is counted among the Big Three and, in recent developments, has been designated a Convox.

The mounted arm of Sarthian forces. In current accounts, they are reported operating on the Plains of Thrania and have driven a wedge between the Fourth and the Thirty-third Legions under General Oxas.

A numbered Bazian legion associated with General Oxas. It is referenced as operating in the Plains of Thrania when Sarthian cavalry drove a wedge between it and the Fourth Legion.

A venerated saunt cited for a conjecture on the rarity of advanced life. The conjecture holds that while many worlds may host unicellular life, very few produce multicellular organisms, and civilizations are rarer still.

A numbered military unit serving under General Oxas. It is referenced during fighting on the Plains of Thrania, when Sarthian cavalry separated it from the Thirty-third Legion.

An honorific of veneration in New Orth and the mathic world, applied to great thinkers, almost always posthumously. Historically intertwined with the term "Savant," it appears in stone as SAVANT (or abbreviated St.) and has spawned several orthographic variants.

A Unarian teacher at Baritoe and a Latter Evenedrician who has written two books engaging with Fraa Paphlagon’s metatheorics; noted admirer of his work.

An avout at the Concent of Saunt Edhar (formerly a fid).

Later observed sharing a private, affectionate moment with Suur Tary near Shuf’s Dowment.

The Pinnacle is the central rooftop tower atop the Praesidium within the Mynster’s starhenge, reached by a double‑helix exterior stair and rising to the highest point of the Mynster. Its roof holds fixed instruments including a noon prism that corrects the clock and a small all‑sky lens known as Clesthyra’s Eye.

A section of the labyrinth within the concent that separates the Decenarian Math from the Centenarian Math. It is used for controlled exchanges with the Centenarians, including questioning across a grate in preparation for the Centenarian Gate and their rare Apert.

A walled scholarly enclave whose members live under a strict Discipline, distinct from the surrounding extramuros world. Maths are central to the "mathic" world and are protected and regulated, with limited use of technology inside their walls.

A restricted compound adjoining the northwest corner of the Mynster, used by the Primate and senior hierarchs within the concent; its grounds include ponds, canals, and fountains fed by the concent's waterworks.

A simple dark‑room pinhole projection used to view the sun safely and record its image. An improvised setup by Suur Ala and Suur Tulia at the Concent of Saunt Edhar enabled careful tracking of brief blue “sparks” near the solar disk.

The most serious formally sanctioned liaison between a fraa and a suur, treated as equivalent to marriage at the Concent of Saunt Edhar. It is a permanent union recognized under the Discipline and is published by a witnessed aut and entered in the Chronicle.

A perforated chancel screen in the Mynster at the Concent of Saunt Edhar that bounds the Decenarians’ nave. It manages sightlines during rites, and its small door is used for controlled entry to the chancel.

An extramuros term for moving‑picture recordings and broadcasts. Avout refer to it when contrasting their meaning of "screen" with the outside world’s usage.

A historical period in the mathic world when a liturgy, drawn from older rites, was practiced throughout the maths. Later descriptions associate it with an "ur-Procian" interpretive trend shortly before the rise of the Mystagogues.

A cohort term for avout in the Unarian Math. Around intake at Apert, some collected youngsters are placed with the One-offs at first, and a subset chooses to graduate into the Decenarian community.

A senior avout bearing the Grandsuur title at the Concent of Saunt Edhar. She oversees public-facing matters during Apert and teaches novices orbital mechanics, beginning with Saunt Lesper's coordinates before moving to orbital elements.

A historical theoric figure associated with Orithena, remembered for driving Enthusiasts out with a rake, coining the term "theorics," and for the cautionary maxim known as Diax’s Rake. An Invocation recited at Saunt Edhar is attributed to him and said to date from shortly after the rake episode.

A fid in a Decenarian math who takes part in Grandsuur Tamura’s discussion on iconographies before Apert, offering the origin of the Temnestrian iconography.

A family of metatheoretical ideas that posit multiple cosmi in addition to the one we inhabit. In current mathic discussion it frames Protism as a simple two‑cosmos case and features in readings of Fraa Paphlagon’s work.

A decennial observance within the mathic world when the Decade Gate opens at sunrise, accompanied by a music-led rite and the concurrent opening of the Year Gate. It is the ten-year instance of Apert and briefly permits regulated contact between the math and extramuros.

A prominent mathic institution and one of the Big Three, noted for strong ties to the Sæculum and a reputation for being urban and worldly due to its harbor setting and the recurring growth of a city outside its walls since the Reconstitution. It is also known for Unarian teaching and scholarship (e.g., Suur Aculoä) engaging with Fraa Paphlagon’s work.

An informal label for a suspected high‑influence fid associated with Suur Aculoä; used as “HIFOSA” when conjectural and “IFOSA” once a candidate is proposed. Some avout identify Ignetha Foral as the likely figure, but confirmation is lacking.

A label used in the mathic world for teachers and adherents associated with Saunt Halikaarn’s semantics‑oriented tradition. In Unarian contexts, some students are said to study under Halikaarnians and go on to praxic or artisan paths; the term denotes an affiliation in teaching rather than a formal order name. The name also appears in comparative scholarship concerning polycosmic ideation.

A mathic complex named for Saunt Muncoster; counted among the Big Three and historically noted for a Syntactic Faculty that, after the Reconstitution, honored Saunt Proc as patron.

A polar region on Arbre noted as part of a long overland route where sledge trains hauled black volcanic stone from the Cliffs of Ecba to the great clock. It is also cited as a focus for auroral observations linked to solar activity in ongoing cosmographic inquiries.

A medical care area within the Concent of Saunt Edhar, cited for its proximity to the Unarian Math and used for treatment of injuries and ailments.

A library building within a Decenarian math, used by avout and occasionally accessed by supervised visitors for necessary repairs. It hosts study and interviews; notably, an interview here between Fraa Orolo and the extramuros artisan Quin—transcribed by Fraa Erasmas—was later reviewed during a Regulant inquiry.

A term for civic townspeople in the Saeculum, especially those living around maths and interacting at gates and during Apert; also an emblematic figure in mathic art and a label used in outsider iconographic narratives.

Trees deliberately cultivated for their leaves, which are harvested, dried, pressed, and aged under stone to make blank pages for books. At the Concent of Saunt Edhar a stand grows between the Decade Gate and the Century Gate, and usable leaves are selected and prepared by members of the community over a long cycle.

A philosophical doctrine attributed to Protas that holds worldly things are shadows of more perfect forms in a higher world. In current discussion it is also framed as an early, simple polycosmic view alongside the Hylaean Theoric World.

A historical label for people who infiltrated the Orithenan tradition and treated numbers as objects of devotion or superstition. They were driven out by Diax, after which his followers identified themselves as theors to distinguish their approach.

A historical saunt cited for "Saunt Patagar's Assertion": that fear of the Terrible Events and the Incanter legend are used by the Sæcular Power to control the avout. She is said to have flourished for a time and founded her own Order.

A later historical form of the Orth language recognized in mathic usage. It is used in formal rites and appears as a period label in reference works, including formulas that date to the Reconstitution.

A cane-forming plant observed in a math’s Cloister garden. It is not among the One Hundred and Sixty-four plants permitted for cultivation under the Second New Revised Book of Discipline, but also not among the Eleven that must be destroyed on sight.

An astronomical nebula named for Saunt Tancred, preserved in a photomnemonic tablet that records the supernova of Tancred’s Star and the remnant’s expansion across centuries. The tablet is used as a teaching image within the Concent of Saunt Edhar, and copies are held among the Millenarians.

A formally recognized, mid‑level liaison type within the mathic world: more serious than a casual Tivian arrangement and short of the permanent Perelithian pairing. It is published before witnesses and entered in the Chronicle after participants consult an elder.

The least serious recognized form of liaison at the Concent of Saunt Edhar. It may be published quickly and is regulated by the Discipline alongside other liaison types.

A total solar eclipse on Arbre in A.R. 3680. Avout at the Concent of Saunt Edhar recall building a camera obscura to view it safely.

The Eleven is the mathic list of plants forbidden within a math (intramuros) for their undesirable properties. Specimens are uprooted and burned without delay and the occurrence is entered in the Chronicle; the list, begun by Saunt Cartas with three species, has expanded over time.

A plant named for Saunt Chandera, noted for a distinctive blossom and listed among the Eleven—plants forbidden within maths. It is recognized in practice as contraband intramuros.

A small reading room off Fendant Court in the Mynster at the Concent of Saunt Edhar, associated by name with the Warden Fendant. Avout use it for quiet study and to consult books kept near the court.

A suur of the Edharian chapter within the Centenarian Math at the Concent of Saunt Edhar. She is named during a rare multi‑name Voco and departs to serve the Sæcular Power.

A revered saunt known primarily through the eponymous plant "Saunt Chandera’s Bane," which is listed among the Eleven—plants forbidden inside maths under the Discipline.

A Centenarian avout of the Edharian chapter at the Concent of Saunt Edhar who was named during a Voco aut and departed with the Evoked.

An avout of the Decenarian community at the Concent of Saunt Edhar. His name was among six read during a Voco, after which he departed under authority of the Sæcular Power.

Theors are followers of Diax’s disciplined tradition at Orithena, adopting the name to distinguish their approach from the Enthusiasts. In historical displays they appear as learned advisers and teachers whose influence extends into the Ethran golden age.

One of the named iconographies used in the Saeculum to caricature the mathic world. It portrays avout as guardians of ancient mystical secrets handed down by Cnous, with talk of theorics presented as a smokescreen for hidden power.

A named historical crisis or turning point referenced in mathic sources, the third in a numbered sequence of Harbingers. It serves as a temporal marker bounding a brief window of stability late in the Praxic Age.

A named iconography in which people in the Saeculum portray the avout as cynical frauds living in comfort at the common people’s expense. It is one of the recurring patterns avout study to anticipate outsider attitudes.

A historical figure associated with the Halls of Orithena whose long-winded debating style is remembered in the great dialogs; his name has become a byword for a smug or pedantic interlocutor.

A leadership title rendered as "First Among Equals" and abbreviated FAE. The term is used for collegial heads within an order or chapter, e.g., for Fraa Corlandin in the Order of the New Circle; it is also applied to the FAE of the Edharian chapter.

The octagonal central space at the heart of the Mynster, enclosed by eight perforated screens and opening toward four great naves. It serves as the primary ceremonial and mechanical locus where avout assemble to wind the clock and to conduct major auts such as Anathem.

Wardens Regulant are the collective body of hierarchs who hold the Warden Regulant office across the maths. As a branch of the Inquisition reporting to the Primate, they provide inward-facing discipline and oversight; in their modern form—instituted after widely reported Third‑Centennial opening mishaps—they have authority to inspect and impose discipline in all maths.

An abstract theoretical framework introduced by Saunt Hemn in the early Praxic Age, also called configuration spaces. These are not physical spaces but coordinate spaces defined by action principles, used to recast problems (such as orbital motion) into more intelligible forms than raw x–y–z coordinates.

Procian is a mathic label for an interpretive stance associated with Saunt Proc and the syntactic tradition. In practice, the term can also describe a rhetorical approach that builds internally consistent, plausible stories to persuade lay audiences.

Rules that define abstract theoretical spaces used by theors, allowing problems to be recast (e.g., describing orbits by elements rather than raw coordinate–velocity). They also constrain how systems evolve from state to state, selecting coherent, plausible paths in configuration space rather than unconstrained hypotheticals.
