Chapter Summary

A named turning point after the Terrible Events that re-centered rites within the Mynster around its clock and that serves as the epoch for A.R. dating; it also formalized the avout’s legal separation from the Sæcular Power.

Arbre is the inhabited world shared by mathic communities and the extramuros society. Off-world contact has progressed from orbital signaling to a probe landing at Orithena on Ecba, drawing both local and Sæcular responses.

A conceptual realm invoked by avout to describe non-spatiotemporal theoric objects and perfect forms; often abbreviated "HTW." In current discourse it frames the "aboutness" of proof and figures in debates about whether information from ideal forms can influence minds in this cosmos.

An umbrella label in mathic usage for God-worshipping communities in the extramuros world, often organized as arks; it can name a particular community or serve as a catch-all that includes traditions such as the Bazian Church and counter-Bazian arks. Deolaters are a common point of comparison in teaching and are at times encountered offering practical help or hospitality.

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.

A senior Edharian avout (Hundreder) first brought to wide notice by his public Evocation at Saunt Edhar; at the Convox he is a leading theoric voice, from Hemn space primers to Protist arguments about the Hylaean Theoric World and interpretations of the visitors’ findings.

The everyday extramuros vernacular of the Sæculum, contrasted with Orth. Avout code‑switch into it when dealing with outsiders, and many Deolater communities use it as the target language for scripture translations.

A senior Saecular leader addressed as “His Serenity,” presented as the Warden of Heaven. In capsule footage he is suited and sent alone to meet the occupants of the icosahedral visitors’ craft; he is later recovered deceased after being ejected toward space, with cause of death left uncertain.

The Hundreders (also called Centenarians) are a mathic cohort whose gate opens only once each century. At the Concent of Saunt Edhar they maintain a distinct community and are associated with the south nave of the Mynster.

An extramuros machinist and close companion of Fraa Erasmas. At Orithena she helps open the Geometers' probe; afterward she becomes engaged to Yulassetar Crade and is sought for her eyewitness account during the Convox.

A daily named hour in the Mynster when the great clock chimes and a small team winds it. It marks midday and is traditionally linked to an ancient oculus rite at the Temple of Orithena.

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.

A periodic ten‑day observance when gates open and limited movement between the maths and the extramuros is permitted; it is the only time the Sæcular Power may step through a math’s gates. 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.

Ecba is a volcanic island closely associated with the Halls of Orithena. A walled compound on its south slope directs a long-running excavation into the buried complex. Recently, witnesses report a destructive strike and eruption at Ecba that drew an emergency cordon by the Sæcular Power.

Orth is the formal mathic language used by avout for study, rites, and intramuros discourse, contrasted with the extramuros vernacular Fluccish. It shows practical mutual intelligibility with clerical Orth among Bazian Orthodox—especially in Old Orth—and is sometimes studied as “Classical Orth” for direct scriptural reading, while remaining the default tongue during organized Peregrin travel.

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 office within the mathic community that enforces the Discipline and assigns penance; its holder oversees an inward-facing watch from high windows beneath the rooftop aerie and is superior to the Master of the Keys, complementing the outward watch of the Warden Fendant. The Warden Regulant and her officers are technically a branch of the Inquisition, report to the Primate, and can depose a Primate in specified circumstances.

A clock-driven portal of the Concent of Saunt Edhar that opens with the great clock's day-night rhythm to control everyday ingress and departures through the Mynster's north nave. It is also cited as the route used by Estemard to leave the math.

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.

A young Tenner suur from the Concent of Saunt Edhar, practical and steady; now present at Tredegarh for the Convox, where she personally fetches Erasmas to Inbrase and offers plainspoken guidance.

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.

An order within the mathic world whose nave in the Tredegarh Mynster is large enough to hold full Convox Plenaries, and that 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.

An extramuros driver from Samble, also called "Gnel," who leads vehicles and logistics for a small traveling party. After the events at Orithena he states he will stay with the Orithenans on a trial basis arranged with Fraa Landasher.

A member of the ten-year mathic cohort, formally a Decenarian and commonly called a Tenner.

An ancient center of learning on Ecba; in recent events its lineage cloister was evacuated after a Geometers’ probe landed and a volcanic flow overran the site. Among participants at a major mathic gathering, the incident is referred to as the “Visitation of Orithena.”

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 late Praxic Age metatheorician associated with the Circle and later venerated as patron Saunt of the Syntactic Faculty. He is assumed to have been liquidated in the Terrible Events, and his name is used in the mathic world as shorthand for a particular "Procian" interpretive stance.

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 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 venerated theor in the mathic tradition associated with pure theorics and a semantics-friendly stance. Late in life he pursued "datonomy" (study of givens) after being locked out of his atom smasher.

A worldwide, poorly documented catastrophe used as the hinge between the Praxic Age and the Reconstitution. Later glosses associate it with so‑called "Everything Killers" and with human culpability, though specifics remain unproved.

Periklyne is the market district of ancient Ethras whose center held a flat public "Plane" for geometrical work and dialog. During the Convox at Tredegarh, the term also names a scheduled interval between Provener and Messal used for mingling and exchanging results.

Voco is a formal aut by which the Saecular Power calls a fraa or suur out of a math for praxic work; within the maths it is treated as a solemn, final departure, and while often a single name is called, the rite can also be conducted as a mass Evocation. In some accounts, "at Voco" is also used as shorthand for the service setting (for example, the chancel/Mynster where the call is read and, during large callings, basic gear is issued to the Evoked).

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 historical designation for the three Thousander maths that remained unbreached during the Third Sack: the Concent of Saunt Edhar, the Concent of Saunt Rambalf, and the Concent of Saunt Tredegarh. The grouping has lately drawn attention through observations of red illumination and a Thousander’s report that the Saecular Power stores nuclear waste at these sites.

A legendary organization name from outsider tales about the mathic world, often paired against the Incanters; avout treat "Rhetors" as iconography rather than a confirmed order. In a widely retold Muncoster story they are credited with "starting" a mysterious manifestation, though avout stress that nothing about it is certain.

An ancient city‑state depicted as the center of a theoric golden age, shown with hilltop temples of the Deolaters, a market called the Periklyne around the base, and a central Plane used for public proofs and dialogs. Ethras is also linked to Protas’s celebrated upsight near a mountain and plain outside the city.

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.

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 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.

The sphere of life and institutions within the walls of the maths, contrasted with the Sæculum outside. In rare circumstances, groups depart under a Convox to travel as Peregrins while striving to preserve the Discipline.

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.

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.

The Discipline is the rule-set governing avout life within maths—defining permitted possessions, conduct, and liaison procedures—and, in practice, how communities such as Saunt Edhar are administered. It also mandates practical measures such as destroying certain proscribed plants within maths and recording such incidents.

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.

Anathem is the solemn, bell-announced expulsion rite by which an avout is permanently Thrown Back from the mathic community into the Sæculum. Distinct from Eliger and Voco, it has been conducted at Saunt Edhar to expel Fraa Orolo.

An icosahedral spacecraft in orbit around Arbre, commonly called the Cousins’ ship or Geometers’ ship. Imagery shows a distributed shock-absorber frame with a single pusher plate, gravel-like shielding, and exterior markings (a geometry proof and unfamiliar glyphs); recent analysis also identifies a detachable, massively dense pod consistent with a thermonuclear device.

An Edharian Hundreder from the Concent of Saunt Edhar, the youngest among the Hundreders traveling in a small Peregrin company toward Bly’s Butte. He hikes with Erasmas and Lio, contributes practical estimates about the icosahedral craft (“the Cousins”), and gives an impromptu calca on Complex Protism, noting he was Fraa Paphlagon’s fid.

A foundational geometric result in mathic teaching, attributed to Adrakhones. High‑resolution phototypes now plainly show a diagram widely interpreted as a proof on the visitors’ icosahedral craft, used as a language‑independent signal in current discussions.

The central tower of the Mynster, bearing the great clock’s dials and anchoring the rooftop starhenge. Its lower reaches house the belfry and carillon machinery; access to the upper works is regulated by portcullises.

An extramuros wilderness guide from near Norslof and cousin of Ganelial Crade. After visible involvement in the Orithena probe response, he becomes engaged to Cord and remains a practical point of contact for witnesses as authorities and Convox attendees seek accounts.

A mathic sanction and resulting status: being "Thrown Back" expels an avout from a math into the Saeculum via the Anathem rite and bars re-entry to maths. "Throwback" is also used as a type-label for such a person.

An iconographic type in the mathic world; the term is also used by avout as a convenient label for certain extramuros proselytizers associated with arks (for example, adherents of the Warden of Heaven), though any formal tie to the community called Deolaters remains unclear. Recently, a volunteer driver was described as “some kind of Deolater” from a counter‑Bazian ark, with the specific affiliation left uncertain.

An avout nicknamed Barb, son of Quin, first entered Saunt Edhar as an extramuros visitor with a knack for mechanisms and was later Collected. After a multi-name Voco, he travels extramuros with a Peregrin cohort toward Saunt Tredegarh, contributing practical insight into observations and local customs.

A theorical term for the complete history of a cosmos represented as a trajectory through Hemn space; current discourse compares Arbre and the Geometers as distinct but closely related tracks with slightly different physical constants, and notes that tracks can fork at quantum contingencies.

A vast nave associated with the Unarians at Tredegarh’s Mynster, described as the only space large enough to hold the entire Convox. It serves as the main hall for whole-assembly addresses and processions during the current gathering.

Heritor of Avrachon’s Dowment and host of the Plurality of Worlds messal during the Convox. Known for moderating discussion, clarifying points, and keeping decorum while engaging directly with Sæcular guests.

Incanters are a legendary order from Saecular stories about the mathic world, often paired against the Rhetors; within the maths the term denotes an outsider trope rather than a confirmed organization. In lore retold here, the "so‑called Incanters" are credited with "finishing" a notorious parking‑ramp incident, a claim presented as folklore.

A reserved avout Hundreder serving as a servitor at Avrachon's Dowment during the Convox at Tredegarh; she is assigned to Grandsuur Moyra and is attentive to messal decorum.

An informal name for a planet icon used to identify one of the four Geometer contingents; speakers sometimes refer to it as “the planet of Quator” when discussing multiple worlds. The image depicts a world whose landmasses lie mostly at low latitudes and appears on the visitors’ craft and on a corresponding sample vial.

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.

An extramuros term for moving-picture recordings and broadcasts; used for entertainment and informal instruction. In casual speech it can also refer to the viewing device.

A mathic title for junior learners within a math, used both as a style of address before a given name and collectively as "the fids." In the present situation, at least one brand-new fid is among those Evoked to travel in a Peregrin group toward a designated Convox while striving to keep to the Discipline.

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.

A concent is the walled complex of buildings and grounds belonging to a mathic community. Many concents exist across the mathic world; in rare cases, a concent is designated as a Convox to receive Evoked avout who will travel together while preserving elements of the Discipline.

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.

Inbrase is a mathic aut that inducts arriving avout into the Convox at the Concent of Saunt Tredegarh, marking the formal end of their Peregrin. Being permitted to celebrate it is considered an honor and a sign of acceptance.

A device for capturing moving‑picture recordings (often called speelies), also known among some avout as a Farspark chambre. Outside the walls it appears as handheld units and public fixtures; within the math it is brought in under supervision and may provide a live feed and magnified view during formal assemblies.

An avout term for ideal theoric truths associated with Protas and the Hylaean Theoric World; used as a notation‑independent basis for communication. The notion is contested by Sphenic/Procian lineages who treat theorics as mental rather than as external realities.

A historic mathic theor at Saunt Baritoe, credited with co‑founding Complex Protism with Fraa Erasmas after challenging a standard two‑box depiction of the Hylaean Theoric World.

A hypothesized future sacking of a mathic concent, invoked as a warning in current discourse among avout. Some voices controversially welcome it, claiming outside intervention would favor the maths.

A historical school of theors associated with ancient Ethras, often set in opposition to Thelenes and his fid Protas in the classic dialogs. The Dictionary frames them as forerunners of Saunt Proc, the Syntactic Faculty, and the Procians, and their corpus later becomes shorthand for a polemical “Sphenic” posture.

A long, rectangular garment used by avout as part of their everyday habit, made of newmatter fibers with adjustable behavior. Beyond everyday coverage, bolts can be tightened for warmth or made sheer for movement, and they serve in improvised fieldcraft alongside the chord and the sphere.

An avout’s adjustable newmatter cord, one of the three standard personal items alongside the bolt and the sphere. It can coil or straighten to change length and tension, serving as a utility line for tying, anchoring, and limited energy-assisted hauling.

An Inquisitor associated with the visit to the Concent of Saunt Edhar during Apert, seen working alongside Onali. Later observed at Tredegarh during the Convox, where he quietly signals Inquisitorial oversight to avout involved in disciplinary disputes.

A term used by avout for civic townspeople of the Saeculum who live and work outside the maths and often gather at gates during openings. It also appears as an emblematic figure in mathic art and is used conversationally to address Sæcular individuals, including officials.

A mathic order, founded by Saunt Lora, known for rigorous historical‑of‑thought scholarship that challenges claims of novelty and helps others avoid reinventing prior work.

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.

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 crag-top math at the Concent of Saunt Edhar, home to the Thousanders and linked to the hall by a long covered stair. It is one of three sites used by the Sæcular Power to house nuclear waste dating from the Reconstitution and was recently traced by a narrow red beam from the sky.

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 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 revered saunt of the mathic tradition whose Saeculum frames the maths as a counterbalance to worldly authority; avout trace many features of their Discipline to Cartasian principles.

A metatheorical stance named for a salon famed for its fresh scones that offers a "third way" between naive realism and total skepticism. The label also denotes its adherents and numbered sects within the mathic world, often called the Sconic Discipline, which treat certain non-spatiotemporal questions as outside productive inquiry.

A mathic complex named for Saunt Muncoster; one of the Big Three. Historically noted for a Syntactic Faculty honoring Saunt Proc and currently hosting a Centenarian Chapter of the Order of Saunt Proc.

Saunt Halikaarn is a venerated figure in the mathic tradition associated with semantics‑oriented lines of thought and cited as a forerunner to Saunt Evenedric in datonomy. His name survives as a living label in current disputes, with “Halikaarnians” often contrasted with Procians.

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.

Mahsht is a large northern port city built around a three-armed fjord, long used as a home port for icebreaker fleets and a major transit hub. Recent accounts describe disrupted harbor operations and ad hoc lodging as military convoys crowd its approaches.

An ancient ceremonial complex at Orithena noted for a domed oculus and a solar rite. Excavated by a math-run community on Ecba until a probe landing and a volcanic event devastated the modern compound.

A leadership title rendered as "First Among Equals" and abbreviated FAE, used within mathic communities for collegial heads of orders or chapters. At Tredegarh’s Convox the term is also used for a delegation’s spokesperson.

A conceptual diagram used in Complex Protism: a fully generalized, directed‑acyclic network that treats theoric and inhabited worlds as nodes and allows arrows leading from Arbre toward other inhabited worlds.

Non‑spatiotemporal mathematical entities invoked by Protists as the ideal objects of proof. In current discourse they are treated as changeless givens perceived from the Hylaean Theoric World, though skeptics argue the mind supplies the definitions.

An avout way of speaking about multiple inhabited worlds (cosmi) and how they might relate. It is an active topic at the Convox, motivated by the arrival of the Geometers and interpreted through competing frameworks.

A metatheoretical claim attributed to Fraa Clathrand that the directed‑acyclic diagrams of Complex Protism mirror ordinary causal flow in spacetime. It is used to explain why givens about cnoöns affect minds one‑way—like influences from the past—without being alterable by present events.

A historical Edharian avout credited with "Clathrand's Contention," noting an isomorphism between Complex Protism diagrams and the flow of time; he is said to have advanced from Centenarian to Millenarian at Saunt Edhar.

A named diagram used in expositions of Complex Protism. It denotes one of the standard motif shapes by which avout picture nodes and one-way arrows of information flow across cosmi.

A theorics term for this world’s local causal domain as used in Complex Protist diagrams. In current Convox discourse it marks the node representing Arbre and serves as a reference point when discussing one‑way information flow between inhabited worlds and the Hylaean Theoric World.

An umbrella term for syntactic‑aligned faculties within the mathic world, historically linked to Saunt Proc and Procian lineages. Sources frame them as a lineage distinct from Semantic faculties, rather than a single order.

A theoric diagramming scheme that depicts how information and causal influence can spread through space and time, constrained by a finite signaling speed. Used as a teaching and reasoning tool to track who can know what, when, and from where.

A named diagram used in Complex Protism; one of several directed‑acyclic graph patterns avout employ to picture one‑way information flow among cosmi. It is cited alongside the Wick and other nicknamed forms in light‑bubble style explanations and in references to Clathrand’s Contention about time‑like causality.

A named diagram used by avout in Protist discussions, cited alongside the Freight Train and the Wick during a Convox tutorial contrasting Simple and Complex frames.

A Convox nickname for a massively dense detachable pod on the Geometers’ ship, inferred to be an ultra-large thermonuclear device capable, if positioned in orbit and detonated, of bathing the facing hemisphere of Arbre in devastating radiant energy.

A prominent champion of Sphenic thought mentioned in The Dictionary; remembered chiefly for the dialog that bears his name, where Thelenes defeats his arguments and he reportedly takes his own life.

An instance of Apert in the Twenty-seventh Century, cited for distributing Fraa Clathrand’s writings across the mathic world; later speakers note it as occurring some decades before the Third Sack.

The physical site within a math’s worship hall where the Voco rite is conducted; typically a screened chancel in the Mynster where names are called and departures begin. In large callings it can serve as a staging point where basic gear is issued before immediate extramuros travel.

A millennial Convox cited as the moment when a Thousander-authored treatise on Complex Protism by Suur Uthentine and Fraa Erasmas was first copied out to the wider mathic world.

A personal, size-adjustable sphere of Newmatter carried by Avout as part of the minimal kit; gesture-controlled to expand or shrink, it serves everyday uses inside a Math and, when Evoked, has been used for rescue and protection.

A cloister at Orithena that identifies itself as the Lineage, presenting math-like forms while operating outside the Discipline. It is closely tied to the Teglon and to the ongoing excavation of the buried temple complex.

A label used in the mathic world for teachers and adherents associated with Saunt Halikaarn’s semantics-oriented tradition, often contrasted with Procians. 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 family of engineered substances produced by controlled nucleosynthesis, allowing tunable mechanical, optical, and structural properties. Current tests at Tredegarh indicate the visitors’ recovered materials are not newmatter but are composed of nuclei incompatible with Arbre’s matter.

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.

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 formal chapter at the Concent of Saunt Edhar within the Decenarian Math. The designation is used by avout to identify their affiliation, including when addressing other cloisters.

A historical noblewoman of the Praxic Age remembered for hosting the salon that catalyzed what later speakers call Sconic thought, addressing how perception through the senses mediates reality. She wrote books drawn from that salon's exchanges and is cited as the enduring figure behind those discussions.

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.

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.

An early theoric figure credited with founding the Temple of Orithena and discovering the Adrakhonic Theorem, which states that in a right triangle the square of the hypotenuse equals the sum of the squares of the other two sides.

A disciplinary text used as penance within the mathic world. Assignees must copy, memorize, and be examined on specified chapters under the Warden Regulant’s authority, typically in seclusion inside the Mynster.

A naturally occurring chemical associated with an easy sense that “everything is fine.” A dictionary account credits its isolation to theors and notes that it became widespread when blithe was engineered to produce it; blithe is treated within maths as one of the Eleven.

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 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.

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.

A former avout of the Concent of Saunt Edhar and early teacher of Fraa Orolo who left via the Day Gate and lives as a Feral at Bly’s Butte; locally he associates with the Samble congregation but is described as attending without belief.

A capitalized term in the Saeculum for organized extramuros affiliations or confessional communities; membership is optional. Arks mobilize practical support (for example, volunteer transport) and circulate information to members via periodic "casts." Some Arks use the Triangle as a central emblem.

A mathic concent named for Saunt Rambalf, long counted with Saunt Edhar and Saunt Tredegarh among the "Three Inviolates." According to Edharian testimony, it is one of three sites where the Sæcular Power stored nuclear waste and was recently singled out by a narrow red beam from above.

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.

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.

An informal nickname on Arbre for one of the visitor-origin groups associated with the Geometers, tied to a polar-ice planet emblem and a distinct matter type in recovered samples. Some accounts now attribute the deceased probe occupant to this group, with implications and alignments still debated.

An informal in-world name for one of four planet emblems associated with the Geometers, distinguished by a prominent polar ice continent. The label is used on Arbre as shorthand for the corresponding visitor-origin group; current reports attribute the deceased probe occupant’s origin to this group, while ballistic fragments from her wounds are reported to be Pangee-type matter.

A provisional human label for a planet emblem associated with one of the Geometer groups; the icon is read as showing a world of many islands. The name is a convenience in current discussions and is not a confirmed self‑designation.

A provisional human nickname for one of four groups among the Geometers now in orbit around Arbre; the label is inspired by a planet icon and corresponds to one of four distinct kinds of matter reported in recovered samples. Circulating analyses attribute projectiles recovered at Ecba to Pangee‑type matter embedded in a deceased visitor identified with the “Antarct” matter type, a reading some cite as evidence of tension between groups; this remains unconfirmed.

A saunt from the Praxic Age credited with developing "Hemn spaces" (configuration spaces), an abstract framework for modeling systems—up to entire cosmi—as trajectories ("worldtracks") rather than raw coordinates.

A label for Praxic‑Age doomsday‑class weapons systems, widely believed—but unproved—to have been used during the Terrible Events; a common view holds that perceived theorical complicity helped precipitate the Reconstitution.

A provisional human label for a planet icon associated with one of the Geometer groups now in orbit around Arbre; the icon is read as showing a world with one large continent, but details remain unconfirmed.

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 named feature within the temple complex at Orithena, closely associated with Provener, and also a term used for a drawn curve invoked by Fraa Orolo in recent events. Observers note that the figure may have conveyed information, though its specific meaning is unstated.

Feral is a mathic label for an avout living extramuros outside a concent. It can describe someone who has left to live independently or, as used in current accounts, an avout presently outside the walls and not under a math’s immediate rules.

A doctrine attributed to Protas that treats things in this cosmos as shadows of more perfect forms in a higher realm.

An earlier historical form of Orth preserved as a liturgical and scholarly register. It is used in formal mathic rites and by Bazian Orthodox clergy, with prayers in Old Orth shown to be mutually intelligible across traditions.

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.

An older suur at Orithena who serves as a gate interlocutor. She upholds entry conditions tied to the Vow and the Discipline and participates in the gate interrogation of Fraa Erasmas.

A solemn pledge presented at certain gates as a condition of entry, described as a promise not to leave once admitted. At Orithena, residents invoke it in gate exchanges, though enforcement there may vary by circumstance.

A rule-bound mathic community in the tradition of Saunt Cartas in which avout live under a Vow not to depart and entry is controlled at the gate. The term is used as a benchmark for a "proper" math and is contrasted with independent lineages, such as the cloister at Orithena, that imitate the form without enforcing the Vow.

A rare Convox held at the Concent of Saunt Tredegarh, cited as the destination for avout who have been Evoked; those dispatched there are expected to proceed to Tredegarh rather than to other maths.

It is common extramuros and is tolerated in limited praxes within the maths, where specific uses have been formally permitted.

A pictographic symbol system used outside the maths, consisting of moving icons that supplanted Logotype in common use. It is used for public labeling, official readouts, advertising, and packaging, and is often contrasted with reading Orth text.

A label used to characterize a view of the Concent as a defensive bastion set in opposition to the Saecular world. It appears in discussion as shorthand for an oppositional, fortress-like stance; some avout, notably Fraa Orolo, reject the designation even while affirming the idea of the mathic world as a counterbalance rather than an accommodation.

A term in the mathic lexicon whose meaning has shifted across eras of Orth: originally a theoric mentor focused on unsolved problems, later a member of a restrictive suvin that discouraged open theoric work, and in current usage a pejorative for those seen to resemble the latter.

A debated concept concerning whether symbols and thoughts genuinely refer to things (possess semantic content) or only manipulate syntax. It is central to disputes between positions associated with Saunt Proc and Saunt Halikaarn and comes up in current discussions about whether sophisticated syntactic devices can "understand."

A long-standing schism in the mathic world between schools associated with Saunt Proc and Saunt Halikaarn, focused on whether symbols possess real "aboutness" or only syntactic structure. The divide is commonly mapped to Syntactic (Procian) versus Semantic (Halikaarnians) traditions and is taught as foundational history.

A longstanding question in the mathic tradition concerning whether thoughts and symbols have real semantic content (aboutness), and whether a purely syntactic device can ever truly "think about" things. It underlies the divide between syntactic and semantic schools and arises in current discussions about interpreting advanced devices and signals.

A millennial convocation held in A.R. 3000. In current accounts it is cited as a point by which long‑running plans could have placed sympathizers across most orders, with Thousanders likely being the hardest to reach.

A historical figure cited as FAE of the Syntactic Faculty at the Concent of Saunt Muncoster after the Reconstitution, associated with the Procian syntactic stance that denies inherent 'Aboutness'.

A term used in the mathic world for the Lorites' outlook and, by extension, an individual aligned with it. It denotes a habit of seeking prior scholarship and precedents rather than speculating or claiming novelty.

In Kelx (Triangle) teaching, Inspiration is the redeeming creative spark associated with the Innocent, said to pass into the Condemned Man and then into all people, empowering them to make the world better. A shipboard sermon explains it as a viral power that can culminate—one day—in a Chosen One who creates a perfect world.

In Kelx (Triangle) theology, the Chosen One is a hoped-for individual who will create a perfect world. If realized, Kelx teaching holds that this perfection would redeem all other worlds and their creators, reaching back to the Condemned Man.

Kedevs are adherents of the Kelx ("Triangle") faith, a term used for the devotees who gather under magisters in individual arks. A dictionary entry defines "Kedev" as a devotee of Kelx.

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.

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.

A Bazian Orthodox monastic house in the extramuros world, mentioned as providing overnight lodging to avout travelers during an ongoing journey.

Directed Acyclic Graphs (DAGs) are described as diagrams of nodes and one-way arrows that do not form cycles, cited as the structure underlying a generalized view of information flow between cosmi. They arise when a simple two-box picture of the Hylaean Theoric World and this cosmos is extended toward "Complex Protism."

Simple Protism is the basic “two‑box” formulation of Protism: one box for the Hylaean Theoric World and one for this cosmos, with a one‑way arrow representing information or causal influence from the former to the latter. It is used as a baseline model in current discussion and is contrasted with expanded treatments such as Complex Protism.

A branch of metatheorics that generalizes the two-box Protist diagram into a directed-acyclic network of cosmi. Accounts credit Fraa Erasmas and Suur Uthentine at Saunt Baritoe; it pictures one-way, wick-like percolation of theorical information from the Hylaean Theoric World.
