Chapter Summary

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.

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.

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.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 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 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 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.

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 extramuros movement centered on a figure styled as the Warden of Heaven that claims a connection to the mathic world and distributes casts. Avout identify it as a contemporary guise of a recurring Moshianic iconography that anticipates avout emerging to enlighten the Saecular world, and they deny any affiliation.

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.

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 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.

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

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.

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. At the Tenth Night ceremony he is named among the youngsters to be Collected and is assigned to come directly to the math at Saunt Edhar.

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.

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 worldly realm outside the concents, contrasted with the mathic world and associated with the Saecular Power; in everyday speech it is also called the Sæcular world.

A traditional corpus of old books and practical lore cited by avout, commonly shortened to "vlor." It provides shared terms, examples, and rules‑of‑thumb that avout use to describe strategies and everyday observations.

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 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.

An elderly avout at the Concent of Saunt Edhar known for opening the Tenners’ screen door before Provener in the Mynster. During Apert he assists with practical tasks and is often described as frail‑looking.

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 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.

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 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 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 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.

An iconographic general type within the mathic world; the term is also used during openings to label religious proselytizers from outside the walls (for example, adherents of the Warden of Heaven), though the text keeps any connection to the iconographic figure ambiguous.

The sphere of life and institutions inside the walls of the maths, contrasted with the non‑mathic world outside. It encompasses avout communities and their Discipline; limited newmatter production inside the maths continues for the bolt, the chord, and the Sphere.

A mechanically actuated gate of the Mynster’s great clock that opens once per year; also called the Unarian Gate. Its opening is driven by an auxiliary cube-shaped weight mounted on the Praesidium’s pillars.

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.

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.

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.

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.

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.

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.

A term for a person brought directly from the extramuros world into a math via the practice of Collection, typically during Apert. It may refer to foundlings or older youngsters who are formally handed over to mathic care.

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 concept describing a figure in a low‑technology society who brandishes a found artifact (such as a glass bottle) to awe others and claim reflected power. In discussion, Fraa Orolo characterizes Bottle Shakers as not inherently dangerous because they are easily impressed.

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.

Rosk is an extramuros manual therapist and the boyfriend of Cord who visits during Apert. He joins communal meals inside the walls, participates in Tenth Night conversation, and comments on shared mental models of the body.

A venerated figure of the mathic tradition, commemorated by a statue on the meadow at the Concent of Saunt Edhar. No deeds or biography are given in the text so far.

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 religious institution observed through its cathedrals, basilicas, and clergy ranks such as prelates and arch‑prelates. Its architecture is noted as a rounded, Bazian style, and other groups sometimes frame themselves in relation to it (for example, as "counter‑Bazian"). It is also referred to as the Bazian faith; an "orthodox" form and consecration are mentioned in passing.

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 authoritative rulebook used within maths to codify practices; it is cited for the "One Hundred and Sixty‑four" allowed plants and defines liaison types, sanctioning a subset.

A named historical turning point in the mathic world’s timeline. It is cited as the point after which the Mystagogue suvin no longer dominated the maths.

A named period of upheaval referenced by the mathic community, frequently mentioned alongside the Harbingers and placed before the Reconstitution. Surviving accounts are fragmentary; in its aftermath, the Hylaean Anathem was revived in a clock-centered form.

Ecba is a named geographic formation of black volcanic rock, cited as the source of stone for the great clock’s counterweights on the Praesidium within the Mynster. The Dictionary also records an ancient eruption of Ecba; historical accounts place the Halls of Orithena on its black rock.

The concent is the complex of buildings and grounds belonging to a mathic community. It is described as the area spread below the Mynster, much of which can be observed from the Warden Regulant’s windows.

The Cartasian Discipline is the formal rule-set to which avout swear, governing life within maths and emphasizing austerity in media and devices. Under it, avout rely on chalk, ink, and stone and restrict visitor devices and recording.

Saunt Halikaarn is a venerated figure in the mathic tradition, invoked as patron of the Semantic Faculty and as the namesake of a “Halikaarnian” posture. In current discourse, he is grouped with Edhar and Evenedric by avout who seek truth in pure theorics, often contrasted with Procians.

An ancient temple and ceremonial complex at Orithena, remembered for its marble‑columned dome and a midday oculus rite; its practices are linked to later mathic liturgy and it is long destroyed.

An order within the mathic world associated by name and interpretive stance with Saunt Proc and the syntactic tradition. Extramuros students who study under Procians are noted to go on to careers in law, communications, or politics.

A liturgical hymn sung by avout during the daily winding rite at Provener inside the Mynster. Often referred to simply as "the Anathem," it addresses Hylaea and exists in many authorized versions; a unison passage helps break static friction to set the great clock’s winding in motion.

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.

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.

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'.

An extramuros craftsman allowed into the New Library to repair a damaged rafter before Apert. A follower of the Warden of Heaven, he later watched Provener from the Mynster’s north nave but, according to Artisan Quin, did not record a speely due to restrictions on his high‑spec speelycaptor.

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 layered polyculture of interplanted food crops grown to be mutually supportive and self‑sustaining, yielding a diverse harvest known as “tangle food.” At the Concent of Saunt Edhar it is celebrated in season and shared during Apert, and is said to predate Cnous with origins on the opposite side of the world from Ethras and Baz.

A mathic term with multiple senses: in Fluccish it denotes false speech and obfuscation, while in Orth it is a more technical label for speech that creates the impression of content without committing to clear meaning. The word’s history includes charged usage by a Halikaarnian lineage and differing connotations inside maths versus in the Saeculum.

A radical order active in the 2nd Millennium A.R., named for Saunt Halikaarn and notorious for loudly denouncing "bulshytt" in others’ speech. They helped sharpen a divide with Procian orders and were all Thrown Back shortly before the Third Sack; later stories often confuse them with the Incanters.

A set of extramuros political divisions referred to collectively by a name that originated when there were four; in current usage they number eight. The term appears in a civic context tied to prefectural reconfiguration and wider satrapial politics.

A disciplinary text cited within the mathic world. When the Warden Regulant "throws the Book" at an avout, they are ordered to complete specified chapters as penance, typically carried out in seclusion within a Mynster cell.

Procian is a mathic label for an interpretive stance associated with Saunt Proc and the syntactic tradition. In a Dictionary usage note, the Knights of Saunt Halikaarn used the phrase “Procian thinking” as an accusation, highlighting a divide before the Third Sack.

A Saecular political term rooted in an earlier four‑part arrangement that has persisted even as the structure now encompasses eight regional units. In current usage it appears in references to the Tetrarchies and their leaders, with the legacy name retained from when there were originally four.

A formal term used within the maths for a high‑ranking Saecular official. During Apert ceremonies, the highest‑ranking Panjandrum present formally transfers foundlings and entrants into mathic jurisdiction.

An extramuros label invoked in civic–religious rhetoric to describe constituencies aligned with a “New Counterbazian” orientation. It is used by a visiting mayor when formally handing newcomers to the math, but no doctrines or specifics are defined in the observed account.

A capitalized term for organized extramuros affiliations or confessional communities. In public speech a person may "belong to an Ark," and some people are noted as belonging to no Ark at all; the text does not define their internal structures.

A formal text attributed to Diax and recited by the Primate in Proto-Orth during Apert at the Concent of Saunt Edhar. It is described as chilly toward Enthusiasts while, for most listeners, serving as a traditional, dignifying start to the proceedings.

A strand of abstract inquiry in the mathic tradition rooted in Diax’s reforms at Orithena, emphasizing rigorous treatment of ideal objects and disciplined reasoning. The Dictionary uses the term in formal definitions (for example, a plane is defined as a two‑dimensional manifold with a flat metric), and avout link it with the caution known as Diax’s Rake.

A historical sacking of Baz associated with the burning of the city’s library. The event is also referred to as the Fall of Baz in authoritative sources.

A historical name used for early followers of Hylaea, contrasted with Deolaters. The label marks the Hylaean path’s focus on abstract forms and theorics rather than devotion to idols or gods.
