Chapter Summary

Members of the mathic community who reside within a math under the Cartasian Discipline. Avout live a cloistered life distinct from the extramuros world, and different communities observe Apert on varying cycles, including century-long intervals for some.

An avout peer of Fraa Erasmas known for physical skill and applied vlor. After joining the Order of the New Circle at Eliger and interning in the Warden Fendant’s court, he initiates a meadow 'weed war' avocation; recently he has pursued odd vlor variations and hand-to-hand drills and offered shrewd remarks on Ita–hierarch dynamics.

The Ita are a practical, segregated organization within the mathic world who tend clockworks and operate tolerated syntactic-device subsystems tied to the great clock, working from quarters adjoining the Mynster. They are readily identifiable by tall stovepipe hats and also enforce device restrictions within the Mynster, including barring instruments that could breach nave separations.

A non-mathic authority acknowledged by avout that tolerates and at times protects the maths, yet can also impose changes on them. It is referred to colloquially as the Panjandrums and is described as operating through various organs.

A walled mathic complex built around the Mynster at a bend of a river, housing multiple maths and governed by ancient rules for opening its gates at Apert. Its central tower (the Praesidium) and rooftop starhenge couple timekeeping to observation.

An extramuros machinist and sib of Fraa Erasmas who works at a metalworks compound near the Century Gate. During Apert she visits inside the Mynster, shows practical curiosity about the clock, and operates a five-axis mill, crafting small items (including titanium jewelry) and also supplying the Ita.

An everyday extramuros vernacular contrasted with Orth. Standard references attest its period-labeled usage and slang, and avout often switch to it when addressing outsiders, especially during Apert.

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.

The great stone‑vaulted complex at the heart of the math, built around the Praesidium and its clock. It hosts rites and gate openings at Apert and provides access to bells and the rooftop starhenge.

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.

Orth is the formal language used within the mathic world, contrasted with the extramuros vernacular Fluccish. The Dictionary tags historical forms—including Proto‑Orth, Old Orth, Middle Orth (often subdivided into Early and Late), Praxic Orth, and New Orth—and sometimes contrasts earlier versus later Orth within entries.

The latest of three historical sackings of the concent, remembered for a siege that led to a one-hour sortie through the Year Gate and a costly return. The lower maths fell while the Thousanders endured in isolation for decades.

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 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 mathic cohort also called the Hundreders, whose gates open only once each century. The phrase "to go Hundred" is a derogatory slang for going mad, linked to infamous centennial mishaps at certain Hundreder maths.

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.

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.

The principal twin-mounted telescope on the starhenge atop the Praesidium at the Concent of Saunt Edhar, named for Saunts Mithra and Mylax. It is part of the clock‑coupled rooftop works used for cosmography and recording images to photomnemonic tablets.

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.

A mathic maxim attributed to Diax meaning you should not believe a thing only because you like to believe it; a self-check to keep judgment from being clouded by preference or emotive wording. Avout also use "Diaxan" to describe neutral phrasing that avoids loaded terms.

Barb is the son of Quin, an extramuros visitor whose keen, orderly mind fixates on mechanisms; during the opening he deduces details of the concent’s bridge-and-gate drive and becomes a persistent presence on tours. Named among the youngsters to be Collected and assigned directly to the math at Saunt Edhar, he is later seen in his second month studying orbital mechanics and progressing quickly.

A recognized mathic order named for Saunt Edhar. At this concent the Thousanders belong to it and it traces its tradition to Saunt Halikaarn; local history credits early members, after the Reconstitution, with shaping the crag and providing stone for the concent’s walls and the Mynster.

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 office within a math responsible for the outward watch from the Mynster’s rooftop aerie. It also coordinates external security posture, especially around Apert, and stands in contrast to the inward-facing authority of the Warden Regulant.

A walled mathic community within the Concent of Saunt Edhar, home to the Tenner cohort (the Decenarians). It houses the New Library and a towering clock central to daily timekeeping, and maintains tightly controlled contact with the outside world.

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.

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.

A senior hierarch at the Concent of Saunt Edhar, described as being in his seventh decade. He has chaired formal Book examinations and led recorded inquiries; as the inquiry into Fraa Orolo intensified, he is associated with actions that involved Ita staff.

The Hylaean Theoric World (HTW) is described as a higher plane of pure theorical objects glimpsed by Cnous and discussed in mathic teaching. Early accounts recount Orithena as a place where theors devoted themselves to exploring this realm of ideal forms.

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.

A named period of upheaval referenced by the mathic community, frequently mentioned alongside the Harbingers and placed before the Reconstitution. Avout commentary links its aftermath to the end of Praxic Age megaprojects and a turn toward cosmography.

A senior avout bearing the Grandsuur title who instructs fids within the Concent. She is seen leading a rigorous review of the Iconographies around Apert and has authority to permit fids to go extramuros.

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 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 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.

An omnibus term in New Orth for armed and unarmed martial arts, military history, strategy, and tactics, closely associated with the avout of the Ringing Vale since a math was founded there in A.R.17. In informal speech it is shortened to "vlor"; extramuros, "Vlor" also names an entertainment genre and a type of academy.

A decennial cohort within the mathic world whose members—called Tenners—live in the Decenarian Math. They occupy the Mynster’s southwest quarter and follow a ten‑year rhythm that allows limited exchange at Apert.

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.

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.

Statho is the Primate who presides over rites in the Mynster, coordinating with the Inquisition and wardens. He intones names during Eliger and Voco and has officiated an aut of Anathem.

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 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.

Protas is remembered as the greatest fid (disciple) of Thelenes, credited with the doctrine that the things people perceive are shadows of more perfect realities in a higher world. His proclamation of this idea—later called Protism—followed a sequence of upsights comparing cloud shadows, clouds, and a mountain’s changing aspect.

Inquisitors are roving officials of the Inquisition who inspect concents and enforce the Discipline. At the Concent of Saunt Edhar, two Inquisitors visited during the current opening and later departed following an Evocation.

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.

The central tower of the Mynster, bearing the great clock’s dials and anchoring the rooftop starhenge. It contains the stair and controlled access to the upper works used for observation.

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.

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.

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.

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.

The inhabited world on which the mathic communities and the extramuros society live. It anchors local timekeeping and skywatching and is referenced in accounts of a past near-miss by a large asteroid.

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 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.

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.

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.

Reticulum is a communication network within the mathic world, described as created by the Ita and used to transmit messages between concents. It is cited as the medium by which centrally issued directions can be sent and received locally.

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 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 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.

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.

A formally constituted avout community at the Concent of Saunt Edhar within the Decenarian math; its members are often referred to collectively as Edharians. Distinct from the Centenarian Chapter, which comprises the Hundreders.

A mathic cohort also known as the Millenarians. At this concent they occupy the crag above the Mynster and attend rites during Apert; locally they are identified with the Edharian Order.

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.

Voco is a formal aut in which the Sæcular Power calls a fraa or suur out of a math to perform practical work. Within the maths it is treated as a solemn, final departure for the person who is Evoked.

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 young avout among the Tenners at the Concent of Saunt Edhar, noted for practical competence and quiet care for peers. She has decided to join the New Circle; she assists with discreet tasks and research while continuing to counsel friends with clear, pragmatic advice.

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.

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 colloquial subset of Vale‑lore focused on using a shovel or spade as a practical tool—sometimes as an improvised weapon—framed within the vlor tradition and invoked informally by avout.

A named shift in practice where theors turned from relying on ever‑larger particle accelerators to drawing testable "givens" from cosmography. It was already underway in the very late Praxic Age and continued after the Reconstitution as megaprojects stalled.

A mountain valley named for the chiming sound of many rills descending from nearby glaciers; also the site of a math whose avout specialize in Vale‑Lore.

A paper book cover repurposed on the starhenge as a protective wrapper for photomnemonic tablets. It is first noted when an Ita technician (Sammann) retrieves one near Clesthyra’s Eye and later seen encasing a tablet carried from the rooftop parapet.

A named rhetorical maneuver in which a speaker abruptly changes the subject so as to imply the prior question has been settled in their favor. It is noted during a discussion between Fraa Lio and Fraa Erasmas, where the customary rejoinder is given as "Hey, not so fast!"

An improvised, tool‑based variant within Vale‑Lore (“vlor”) that treats a garden rake as a weapon or training aid. It is mentioned as an informal experiment rather than a codified discipline, and is noted for the risk of puncture wounds.

Saunt Bunjo is a venerated figure in the mathic tradition, cited by name in the shorthand “Saunt Bunjo’s” for a Millenarian math built around a deep salt mine where avout conduct long‑timescale detector experiments. No biographical details are given; the associated math publishes results on a thousand‑year cycle and reported only a few tentative flashes in its first millennium, with none since.

A named claim attributed to Saunt Patagar holding that fear of the Terrible Events and the Incanter legend are used by the Sæcular Power to control the avout. Avout cite it as a lens when discussing surveillance and the management of information between authorities and the maths.

A seasonal marker in the mathic calendar. It is used as a reference point between equinoxes and is mentioned as a time marker for events at the concent.

The math established in A.R. 17 at the valley called Ringing Vale. Its avout are known for a long‑standing focus on Vale‑lore—martial arts and related studies such as military history, strategy, and tactics.

A Millenarian math built around a deep salt mine where avout keep watch for rare flashes in crystalline particle detectors. It is known for publishing results on a thousand‑year cycle and is referenced as an exemplar of long‑timescale experimental work.

A hardy plant noted on the grounds of the Concent of Saunt Edhar; it can be directed as it grows and is tended by avout in the meadow.

A seasonal marker recognized in the mathic calendar. It prompts local observances within the concent and serves as a reference point relative to other timed practices.

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.

An avout stone‑mason remembered as the originator of Shuf’s Dowment and namesake of a mathic Lineage. His simple meditation tower, begun around 1200, grew over generations into deep cellars later tied to wealth and reforms after the Third Sack.

A named balcony level within the Mynster at the Concent of Saunt Edhar, associated with the Warden Fendant. It sits above the Regulant court and serves as a passage toward the upper works, decorated with martial statuary.

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."

The Discipline is the rule-set that governs life inside the maths, defining what avout may possess, how they conduct themselves, and which types of liaisons are sanctioned. At Saunt Edhar it permits a minimal personal kit (bolt, chord, and sphere), with local practice allowing footwear during Apert and in cold months without punitive action so far.

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 collective term for three historical sackings of the concent, also referred to as Sacks-General when distinguishing them from local sacks.

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 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.

One of the three historical sackings associated with the Concent of Saunt Edhar and its Mynster. Mathic sources also cite it as a turning point after which praxes were curtailed, specific exceptions were formally allowed, and the Ita’s segregated maintenance role around tolerated syntactic subsystems was reinforced.

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 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 math set on a crag east of the Mynster, home to the Millenarians (the Thousanders). It connects to the Mynster by a covered, hand‑carved stone stair that reaches the southeast corner.

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.

An original library building within a math that opens directly onto the Cloister. It is noted for an ancient, glass-smooth stone floor far older than the floor of the New Library, and it houses very old volumes, including tomes rarely handled for centuries.

A rule of thumb attributed to Fraa Gardan that prefers simpler, less complicated hypotheses, likened to a steelyard balance. Also called Saunt Gardan’s Steelyard or simply the Steelyard.

Baz is a historic city and imperial center referenced through displays in the Hylaean Way, famed for its temples, capitol, walls, roads, armies, library, and the Ark of Baz. Later accounts depict its sack and the burning of its library, remembered as the Fall of Baz.

The vast airy space behind the Præsidium’s dials in the Mynster where the great clock’s chains, gears, and escapements converge. It is tended by the Ita and houses upper works critical to keeping the clock running during winding and rare interruptions.

One of the four cardinal naves of the Mynster, aligned with the north façade. It serves as the entry and viewing space for extramuros visitors allowed to observe auts such as Provener, under supervision by the Ita who may restrict recording devices.

A young avout at the Concent of Saunt Edhar, first noted for his clear explanation of the Temnestrian Iconography; later referenced as a cellmate of Fraa Erasmas and Fraa Branch during a hierarch inquiry in Apert.

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 revered saunt of the mathic tradition, credited with the treatise Saeculum and cited in the Discipline for forbidding all forms of liaison in early codifications.

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 hierarch who serves as deputy to the Warden Regulant and manages portcullis access to the Praesidium stair and Starhenge, typically scheduling night access. When directed, the office can seal the upper works entirely.

Eliger is a ceremonial selection and vow‑taking rite, signaled by bells after Apert, in which Tenners publicly choose and are bound to an order within the mathic community.

An interior court within the Mynster at the Concent of Saunt Edhar, associated with the Warden Regulant. A parapeted inner walkway circles the space and opens onto penance cells whose arches face the court while their windows look out over the meadow.

A widely remembered near‑impact episode when a large asteroid was believed to be on course for Arbre. The scare mobilized avout and authorities, left lasting observational practices, and the name is now used as shorthand for any such imminent‑impact scenario.

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.

A capitalized term for organized extramuros affiliations or confessional communities. People are described as joining different kinds of arks to feel part of a stable, ongoing project that propagates their way of life; membership is optional and varies, and specific structures remain undefined.

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.

A small chalk hall named for Saunt Grod within the Cloister at the Concent of Saunt Edhar. It serves as a teaching room for fids and features a stained‑glass window above the slate depicting Saunt Grod and his assistants under duress.

A saunt referenced as the namesake of “Saunt Lesper’s Coordinates,” an x, y, z framework used in teaching the basics of orbital motion. In practice it yields six component numbers (position and velocity along each axis) and is presented as a more tedious, less intuitive approach than orbital elements.

A high‑resolution imaging feature cited as part of an extramuros speelycaptor. Mentioned alongside “SteadiHand” and “DynaZoom,” it was referenced as a reason a recording device was considered too capable to be permitted inside the Mynster.

A named feature associated with extramuros speelycaptors, cited alongside Eagle-Rez and DynaZoom as part of a high-end setup. In-story inference suggests it denotes image stabilization to reduce hand shake; it is mentioned in connection with concerns about recording inside the Mynster.

Amnectrus was the Warden Fendant at the time of the Third Sack, remembered for holding a defensive position with a rifle for the last twenty hours of his life. A life-sized bronze of Amnectrus stands in the Warden Fendant’s court, with his actual rifle and spent casings displayed and his sarcophagus serving as the pedestal.

A named zoom/magnification capability on an extramuros speelycaptor, cited alongside Eagle-Rez and SteadiHand. Its inclusion—combined with those features—was given as a reason to block recording of Provener inside the Mynster.

Saunt Grod is a venerated figure in the mathic world, known at the Concent of Saunt Edhar for a chalk hall that bears his name. A stained-glass window there depicts him and his research assistants being beaten in the dungeons of a Praxic Age spy bureau.

A former avout and one of Fraa Orolo’s teachers who renounced his vow and left the math. He became a Feral based at Bly’s Butte, where he hand-built a telescope and sent periodic letters describing his observations; beyond that, his present affiliation is not specified.

A local butte associated with the Concent of Saunt Edhar, named for Saunt Bly and cited as a favorable site for astronomical observing. Mathic lore holds that slines killed Saunt Bly there; after renouncing his vow and leaving the math, Estemard built a telescope on its summit, though any current observatory status is unclear.

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.

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.

A mathic term for the wealth and estate associated with a lineage, sometimes extending to the named site where such property was kept (for example, Shuf’s Dowment). Lineages and their dowments were abolished in reforms following the Third Sack, though physical sites and stories about them remain.

A small rooftop instrument on a low pedestal beside Clesthyra’s Eye atop the Pinnacle, visible in all‑sky recordings as a fixed notch and kept clean by the Ita.

A recurring period surrounding Eliger marked by recruitment talk and politicking among avout. At the Concent of Saunt Edhar it is cited in rumors attempting to link an instance of Anathem to that season’s politicking.

In extramuros usage, lineage means hereditary descent; in the mathic world it once referred to a chain of avout who inherited property beyond the standard kit, a practice later abolished after the Third Sack. Rumors of such wealth fed outsider portrayals of avout as living in undue comfort.

A stand of page trees forming a coppice on the rise between the Decade Gate and the Century Gate of the Concent of Saunt Edhar. It lies along the path to Shuf’s Dowment across the river.

An Orth term meaning “within a math’s walls,” used to mark the mathic‑world sense of words and practices as distinct from their use outside. As used in current texts, it qualifies definitions such as “Lineage (Intramuros),” a chain of avout holding property beyond the basic kit (bolt, chord, and sphere); such lineages were later abolished following the Third Sack.

A school within the mathic world oriented toward the later writings of Saunt Evenedric; cited as the intellectual affiliation of Suur Aculoä, a long‑serving Unarian teacher at Baritoe.

A saunt of the mathic world known for disproving a once‑popular elementary particle theory; his name is cited as the authority whose result ended its fashion.

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.

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.
