Chapter Summary

Orth is a language used within the mathic world, contrasted with extramuros speech such as Fluccish. The Dictionary distinguishes multiple historical forms—including Proto Orth, Old Orth, Middle Orth (sometimes divided into Early and Late), Praxic Orth, and New Orth—and sometimes contrasts earlier versus later Orth within entries.

A cosmographer and avout of the Decenarian math who mentors Fraa Erasmas, conducts probing interviews with visitors, and leads a praxic orbital‑mechanics effort tied to observations from the starhenge.

An avout of the Decenarian Math at the Concent of Saunt Edhar; he serves on the clock‑winding team and assists Fraa Orolo. During the present Apert he goes extramuros with a peer, reconnects with family, and guides a visitor to see the clock.

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.

An authority within the mathic community who enforces the Discipline and assigns penance; the office is also tied to an inward-facing watch from high windows beneath the rooftop aerie, complementing the Warden Fendant’s outward watch.

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 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 figure from the great dialogs known for trapping interlocutors and dismantling their arguments. He is cited in The Dictionary as a historical person confined before execution and was mocked by Temnestra's satirical play The Cloud-weaver; accounts specify he was executed by the Saecular Power following a judicial proceeding.

A daily named hour within the Mynster’s routine when the great clock chimes and a small team of avout wind it. During Apert, visitors may be allowed to observe under supervision, and wardens sometimes address matters immediately after the observance.

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; he later arrives at Apert with his son and offers candid observations about life outside the walls.

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, and is seen coordinating responses during the opening of the gates.

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.

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 central tower of the Mynster that carries the four great clock dials and anchors the upper works, including the starhenge. It houses the main weights and winding mechanisms that drive the community’s great clock.

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.

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.

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.

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.

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.

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.

A senior hierarch based at the Mynster who presides over major rites and, in retirement rites, calls the name of the retiring hierarch and names a successor. The office is associated with a restricted compound at the Mynster's northwest corner. The Primate also directs the Master of the Keys regarding portcullis access to the starhenge for approved observations.

A revered figure invoked in mathic liturgy, associated with the dawning of Light and the transition from chaos; named in the hymn as the father of Hylaea and Deät. Outside the maths, Cnoüs is also cited in Sæcular iconographies as the supposed source of hidden mysteries.

A clock‑driven portal at the Concent of Saunt Edhar that opens daily to admit and route visitors from extramuros into the Mynster’s north nave. Its operation is coupled to the great clock’s works and timed to sunrise and sunset.

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.

The most recent of three historical sackings of the concent. It is cited as a turning point after which standards declined, and its aftermath left the concent largely empty for decades while the great clock sustained itself in hibernation.

A named high ledge within the Mynster associated by name with the Warden Fendant. It is mentioned as reachable by a spiral stair rising in the Tenners’ southwest corner of the Mynster.

A mathic cohort also called the Hundreders, whose gates open only once each century. They maintain their own math across the meadow and prepare for opening through grated interviews in the upper labyrinth; on scheduled nights they have sole access to the starhenge under portcullis control.

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 order within the mathic community, formally known as the Order of the New Circle, led by a First Among Equals. It maintains a chapter house within the concent; associated figures include Fraa Corlandin (FAE) and Suur Trestanas (a member who serves as Warden Regulant).

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.

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 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.

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.

A young suur and fid in a Decenarian math, noted for assertive leadership—especially around bells—and regarded by peers as likely to become Warden Regulant. During Apert she responded quickly when peers returned injured, organizing cleanup and assisting with first aid alongside a visiting artisan.

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.

The east-facing nave of the Mynster, officially the building’s formal entrance. It is currently little used and generally stands empty.

A named forum or place in mathic lore associated with Kefedokhles and Protas, and invoked as the source of the combative style called Periklynian dialog. Its exact nature or location has not been specified in the material available so far.

A legendary or apocryphal mathic order said to operate on a ten-thousand-year cycle. Mentioned in discussion at Saunt Edhar as a claim by avout who supposedly emerged at an Apert, its existence is disputed and often treated as illustrative rather than historical.

A term for avout in the Unarian math. In rare cases, an exceptional One-Off may pass early through the labyrinth to join the Decenarians rather than waiting until Apert.

A thought experiment about slight time slippage between loosely linked causal domains. Introduced and applied by Fraa Orolo as a practical lens for noticing unexpected divergences between life inside a math and the world outside.

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.

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.

A formal convocation associated with the language Orth. The A.R. 3000 session is cited as the moment when the term “saunt” was accepted into standard usage.

A venerated saunt associated with the supernova later called Tancred's Star. Accounts credit him with recognizing the event and installing a photomnemonic tablet to record it nightly, producing the long-running record known as Saunt Tancred's Nebula.

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.

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.

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.

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.

Saunt Halikaarn is a revered figure in the mathic tradition, venerated as patron of the Semantic Faculty. The Edharian Order is said to trace its lineage to him, and “Halikaarnian” is used in-world to label a semantics-oriented way of thinking.

A recognized mathic order whose members are called Edharians. At this concent the Millenarians (the Thousanders) all belong to it, and the order traces its tradition to Saunt Halikaarn. The name is also used informally to describe a working circle associated with Fraa Orolo.

A legendary organization named in popular stories about the mathic world, typically cast as the counterpart to the Incanter; avout treat "Rhetors" as an outsider trope rather than a confirmed order.

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 courtesy title used in the Saeculum for skilled craftspeople and tradespeople, placed before a personal name. Avout use it to address extramuros workers admitted for necessary interactions such as repairs or during limited openings.

Barb is the son of Artisan Quin. During Apert he enters the Concent of Saunt Edhar as a visitor and shows quick, precise insight into the bridge and gate‑opening mechanism, identifying its catenary arch and concealed universal joints.

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 syntactic device (often shortened to "syndev") is a processor-driven mechanism that can generate text and control tools or instruments by making decisions based on measurements. It is common extramuros and is tolerated in limited praxes within the maths, where specific uses have been formally permitted.

A dark, glassy imaging tablet used with rooftop instruments to record and replay night‑sky observations across time. It embeds a syntactic device that lets users scrub through layers of nightly exposures and zoom into details; its use is tolerated within the Discipline as a grandfathered praxis.

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.

Incanters are a pluralized, legendary order from Saecular stories about the mathic world, often portrayed as heirs to Halikaarnian traditions and set against Rhetors. A mathic account notes that this myth took shape in the days leading up to the Third Sack, and it is treated within the maths as fiction or shorthand rather than a confirmed organization.

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.

The principal large telescope mounted on the starhenge atop the Præsidium 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.

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 hierarch who serves as deputy to the Warden Regulant and manages nightly portcullis access to the Praesidium stair and Starhenge. The office implements the Primate's directions and schedules which math has access during the hours of darkness.

A philosophical doctrine attributed to Protas that holds worldly things are shadows of more perfect forms in a higher world. It is invoked within mathic discourse as an interpretive lens rather than an organized order.

A colloquial term for a relationship that meets only during the brief decennial opening of the gates, named after a Decenarian fraa said to have seen his true love for ten days every ten years and spent the rest writing poems to her and smuggling them out of the math.

A brilliantly bright supernova observed by Saunt Tancred and preserved in a photomnemonic tablet whose layers replay the event. Its remnant is known as Saunt Tancred's Nebula.

An extramuros institution for children, commonly called a "stabil"; the older full form "Stabilization Center" survives mainly as etymology. In practice, stabils provide daily care, meals, and screen-based instruction, with coaches delivering children to and from the site.

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.

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.

Sammann is an Ita connected to practical maintenance at the concent; during Apert, Cord mentions making a precision metal part for him earlier that day.

A named outsider iconography that portrays avout as abductors who “take” people—especially children—into the maths. In the current context it is mentioned as a pattern a local resident does not subscribe to when describing a Collection as voluntary.

The fourth edition of an in‑world reference work, cited as “THE DICTIONARY, 4th edition, A.R. 3000.” It is quoted for the headword “sline,” presenting numbered senses with usage notes that indicate preferred and deprecated meanings.

A Mathic term for an adversarial style of exchange; a "Periklynian dialog" is explicitly described as combat, contrasted with cooperative or instructional forms of dialog.

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.

A venerated saunt of the mathic tradition associated with the Lorites and the so-called "Last Idea." She is credited with Saunt Lora's Proposition, set in the Sixteenth Century, asserting that every idea had already been conceived by that time; her influence remains widely debated.

A mathic community named for Saunt Rab. It stands on the site of a Praxic Age laboratory where a spaceship was built by avout for an asteroid‑deflection mission that became a study mission when the rock was calculated to miss Arbre.

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.

An extramuros cohort identified as followers of the Warden of Heaven, referred to collectively by avout as “Moshianics.” They are associated with the Moshianic Iconography that expects revelations at gate openings.

A term in the mathic tradition for a teaching-style exchange where a mentor instructs a fid. It is contrasted with a peregrin dialog between equals and a Periklynian dialog, which is combative.

A term in mathic discourse for a style of dialogue between equals who wander together to work something out. The name also refers to an ancient philosophical tradition, cited as anticipating ideas later discussed by a renowned Saunt.

Ethras is a named place referenced in a classical anecdote. Protas climbed a mountain near Ethras and looked over the plain that sustained a city‑state, a scene associated with his famous upsight.

A revered Saunt cited as co-namesake of the great telescope mounted on the starhenge above the Præsidium at the Concent of Saunt Edhar. No biographical details are provided in the present account beyond the instrument bearing this name.

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 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.

Non-mathic people who live outside the maths in the worldly realm known as the Saeculum; avout sometimes call them "extras." During gate-openings at Apert, they gather at the gates to watch, record, petition, or offer gifts, and they live under the authority commonly called the Saecular Power.

A concept urging speakers and writers to strip claims of loaded or emotive wording to reach neutral formulations; avout also use "Diaxan" as an adjective for such phrasing. It is invoked as a self-check to avoid letting imagination outrun what is known.

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.

Statho is the Primate, a senior hierarch associated with the Mynster who presides at rites and announcements. He named Suur Trestanas as Warden Regulant and is seen during Apert alongside the Warden Fendant.

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 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.

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.

A legendary figure in Saecular lore associated with the mathic world, imagined to alter physical reality by coded utterances. Popular fiction amplified the idea; within the maths it serves as shorthand for implausible power, and some scholars link such misconceptions to the Third Sack.

A mythic figure invoked in mathic liturgy, described as a daughter of Cnous who brings his Light; central to the Hylaean Anathem. Avout also refer to "mother Hylaea" when speaking about abstractions.

A title in the mathic world for junior learners within a math, used collectively and as a formal style of address before a given name (e.g., "Fid Erasmas"). Fids study and work under elder avout and often move as a cohort or "crop" toward transitions around Apert.

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.

A named historical dispersal referenced in mathic liturgy. It is cited as a turning after the Old Mathic Age and before the Praxic Age, during which older rites fell out of practice, later contrasted with their revival after the Terrible Events and the Reconstitution.

A colloquial subset of Vale-lore concerning the behavior and control of fire, including practices like setting counterfires—invoked by avout as “fighting fire with fire.”

A simple knot used by avout to secure the bolt of their garment for modesty. It is observed in use when Lio wraps the selvage end of his bolt around his waist and between his thighs.

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.

An ancient ceremonial complex remembered for its marble-columned dome where theors gathered at midday beneath an oculus. Its rite is cited as a precursor to elements of mathic liturgy now practiced within the Mynster.

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 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.

The south-facing nave of the Mynster, reserved for the Centenarians and directly reachable from their side of the meadow. It serves as their principal gathering space for rites viewed through the chancel screen.

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

A disciplinary authority referenced by avout as an enforcer of rules within the mathic world. It is invoked as the body that could punish communities for stretching or violating strict practices, with no direct action observed in the current context.

A term used in mathic sources for a numbered series of historical crises or turning points. The era associated with them is often mentioned alongside the Terrible Events, and its details are obscured by poor record preservation.

An in‑world expression referencing Cnoüs, invoked as a figurative light before which a saunt might gaze in rapt contemplation. It is mentioned in the context of avout ritual at Apert and is tied to sauntly iconography.

A recurring set of named stereotypes and narratives by which people in the Saeculum depict the avout and the mathic world. Avout study these patterns to anticipate outsider attitudes and reactions during contact extramuros.

A recurring popular image of the mathic world derived from a Praxic Age entertainment about the villain Yorr. It portrays avout—often labeled as theors—as criminally deranged praxic schemers bent on taking over the world.

A named iconography from a Praxic Age entertainment serial that shapes how some in the Saeculum view the avout. It casts avout as valuable, highly rational specialists whose very strengths make them seem emotionally limited and subordinate to intuitive leaders.

A young avout in a Decenarian math, noted by Fraa Erasmas and addressed as Fid during instruction. She shows quick insight during a review of the Iconographies.

A named order within the mathic world associated by name and outlook with Saunt Proc’s syntactic tradition. In popular iconography, "Rhetors" are said to be linked to the Procians, though avout caution that such portrayals blur distinctions among orders.

A fictional villain from a Praxic Age entertainment serial, used as shorthand for a popular iconography that portrays avout as dangerous, scheming experimenters. In portrayals he is a green-skinned, tentacled laboratory figure labeled a theorician but behaving like a praxic.

A rare, thousand-year opening associated with the mathic gate system. In current discussions it is invoked within the Moshianic iconography, which anticipates the avout emerging through the gates to enlighten the Saecular world and draws pilgrims.

A recurring outsider belief pattern about the avout that predicts they will emerge from their gates to enlighten the world. Considered highly dangerous because it inflames expectations and draws crowds; it is described as ascendant in connection with a figure styled as the Warden of Heaven.

A label invoked in popular entertainments as the supposed heritage of fictionalized Incanters. The Dictionary notes this alleged association as part of exaggerated portrayals that some failed to distinguish from reality prior to the Third Sack.

One of the named iconographies by which people in the Saeculum depict the avout. It frames the theor as an awesomely wise elder statesman who can solve the problems of the Saecular world.

A named iconography—one of the recurring caricatures Saeculars use to simplify the mathic world—portraying avout first as harmless fools and then as sinister corrupters. Traced to the satirical play The Cloud-weaver by the Ethran playwright Temnestra; it is regarded as highly dangerous in practice.

A young avout in the fids' crop at the Concent of Saunt Edhar. During a chalk-hall session led by Grandsuur Tamura, he explains the Temnestrian Iconography.

A rare opening of the hundred-year gates associated with the mathic world. The approach of this event heightens expectations among outsiders and can draw large numbers of visitors.
