Chapter Summary

The Sæcular Power is the umbrella label avout use for whatever worldly authority governs beyond mathic walls; in the present era it is described as a federation whose units roughly align with continents. Since the Reconstitution, avout stand outside its legal system—lacking identity documents and ordinary entitlements—and heed its formal directives only when properly conveyed through rites such as Voco.

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.

Arbre is the inhabited world shared by mathic communities and the extramuros society. Off‑world contact has progressed from signals and a probe at Orithena to shipboard negotiations aboard the Daban Urnud, culminating in opening ceremonies and a co‑signed peace accord.

An elder Thousander of the Concent of Saunt Edhar, known for calm, exact speech and first‑principles reasoning. Evoked to the Convox at the Concent of Saunt Tredegarh, he recognized evidence tied to the Orithena excavation, quietly sent Erasmas north to find Orolo, and later articulated a Hemn‑space “Narratives” view and the Rake’s caution while taking part in a Plurality of Worlds messal. At the Caravansery of Elkhazg, he demonstrated masterful tiling by completing a new Teglon solution overnight.

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.

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.

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.

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 long-cycle mathic cohort also known as the Millenarians. At the Concent of Saunt Edhar they occupy the crag-top Millenarian Math and are identified with the Edharian Order; they play a central role in millennial Convox business, including dictionary compilation.

An era following the Rebirth and ending with the Terrible Events, marked by intensive application of theorics ("praxis"), large-scale industry, and sustained avout–Saecular interchange. Current accounts place the high-water mark of its civilization near the emergence of Sconic thought, with later reforms consolidated at 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 major mathic concent counted among the Big Three and currently serving as a designated gathering point for Evoked avout. Erasmas describes it as older and much larger than the Concent of Saunt Edhar, with a milder climate and lush gardens.

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.

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

A small handheld device common extramuros with a screen and communications functions; beyond photos and media playback, it can record and stream over the Reticulum when available. Inside a math, communications are disabled by the Discipline, but offline functions such as timekeeping and playback continue to work.

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.

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

A principal day-facing gate used at mathic concents, often coupled to the great clock for ordinary ingress and departures. At Saunt Edhar it opens with the clock's cadence; at Tredegarh it serves as the lofty main entrance; it is also cited as the route used by Estemard to leave the math.

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.

First Among Equals of the Ringing Vale and a senior Valer Evoked during the current crisis. He leads a four‑Valer boarding action against the World Burner on the Daban Urnud; after crippling the installation and securing a vertex with Suur Esma, he dies when responders breach the sealed node.

A senior Sæcular official addressed as "Madame Secretary," noted for mathic ties via Unarian study and a decisive public break with the Warden of Heaven. Present among the Arbran delegation aboard the Daban Urnud, she continues to operate as a high‑level interlocutor between the Sæcular Power and mathic actors.

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.

Daban Urnud is an Urnudan starship whose name means "Second Urnud." A Laterran informant describes it as the last and largest of Urnud’s atomic‑propelled craft, originally built for a short interstellar colonization attempt and later refitted as the intercosmic vessel driving successive "Advents."

A linguist from Laterre who infiltrated the Tredegarh Convox disguised as “Fraa Zh’vaern.” Recognized among the visitors for Orth and avout expertise, he later helps guide entry via an observatory airlock on the Daban Urnud and confers with an on‑duty Fthosian astronomer.

An alliance of the worlds Urnud and Tro, known in their own languages as the Pedestal. According to a Laterran informant uncovered at the Convox, Pedestal intelligence infiltrated Tredegarh disguised as Matarrhites to probe claims about Incanters, and its leadership is feared to consider pre‑emptive force.

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.

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.

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.

A mathic order named for Saunt Edhar, locally identified with the Concent of Saunt Edhar’s Thousanders and associated with large praxic works. Edharians also founded a field math on Ecba to excavate the Temple of Orithena; more recently, members organized theoric work concerning an orbital visitor and were Evoked toward a Convox at the Concent of Saunt Tredegarh.

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.

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 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 Valer associated with the Ringing Vale, serving as the cell’s physician during the orbital mission. She helped cluster payloads and treated teammates after launch, and was later killed during the Valers’ boarding assault on the World Burner.

A Valer recognized for decisive, protective action in Old Mahsht; later a member of Cell 317 who helps with suit preparation at Elkhazg and, in orbit, helps re‑establish a Reticulum link during payload consolidation. During the approach to the Daban Urnud he joins the Ringing Vale’s boarding run toward the World Burner and is killed by flying debris amid the detonations.

A legendary label from outsider lore about the mathic world, often paired with the Incanters and treated by avout as iconography rather than a confirmed order. A dictionary entry describes a "Rhetor" as a figure associated with Procian tendencies who is said to alter the past by manipulating memories and records; within the maths this is framed as folklore rather than confirmed praxis.

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.

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).

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 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.

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.

A named event used at the Convox to refer to the encounter at Orithena with a visitors' probe and its immediate aftermath. It prompted urgent assemblies, quarantine measures, and ongoing investigation by avout and the Sæcular Power.

A label for Praxic‑Age doomsday‑class weapons systems, widely believed—but unproved—to have been used during the Terrible Events. Recent events aboard the Daban Urnud describe an activation that produced lethal radiation focused on living beings.

A presented Matarrhite delegate identity at the Tredegarh Convox, seated as a doyn at the Plurality of Worlds messal in Avrachon’s Dowment. The figure was later revealed to be a cover used by the Laterran linguist Jules Verne Durand; the persona’s actions at table are documented from observers’ reports.

A Valer of the Ringing Vale identified at Tredegarh and remembered for charging a sniper in Mahsht. Later she boards a vertex on the Daban Urnud with her cohort during the strike on the World Burner, seizing hostages and sealing the area before dying when the compartment is vented.

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.

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.

A free-standing desert landmark near the Concent of Saunt Edhar named for Saunt Bly. Reached from the settlement of Samble by a spiraling road, its compact summit holds layered ruins, a handmade telescope, and a secluded work area associated with Fraa Orolo.

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.

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.

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.

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.

A theoric term used by some avout to denote a complete cosmos understood as a single worldtrack in configuration space. In current discourse it also frames contact with multiple visiting peoples and, in new proposals, how weak inter-cosmi crosstalk through the Wick—amplified by consciousness—might steer or connect such cosmi.

A conceptual diagram used in Complex Protism: a directed‑acyclic network of theoric and inhabited worlds that frames one‑way percolation (the "Hylaean Flow") and can include arrows leading outward from Arbre toward other inhabited worlds.

The earliest of three historical sackings affecting the Concent of Saunt Edhar. In current accounts it serves as a historical marker; reforms after it restricted syntactic devices, defined the Ita’s role, and forbade avout from conducting further newmatter work while grandfathering a few specific praxes.

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

A theistic mathic order known for keeping to themselves and for reserved participation in wider mathic life. During the Convox at Tredegarh, impostors posing as Matarrhites were unmasked; reports indicate the true order was being held, unharmed but incommunicado, at their own concent.

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

A 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.

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 opposition tendency aboard the starship Daban Urnud, aligned with the Gan’s strategic authority and set against the Urnud/Tro leadership known as the Pedestal.

The Command is the leadership cadre among the visitors aboard the starship Daban Urnud, directing inter‑cosmic travel and the conduct of Advents. Accounts describe competition among the four peoples—Urnud, Tro, Laterre, and Fthos—for positions within it, and note that linguists are prized during Advents.

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 Laterran woman from Laterre and the wife of Jules Verne Durand. Identified as the deceased passenger of a probe recovered at Orithena; during opening ceremonies aboard the Daban Urnud, her coffin was honored and transferred to Laterran care.

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.

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.

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.

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.

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.

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.

An ancient Cartasian complex famed for plane‑geometry tilings, founded by early avout after the Fall of Baz. No longer a math, it operates as a privately maintained caravansery and river crossing, presently overseen by Heritor Magnath Foral.

One of sixteen rotating habitat spheres aboard the Daban Urnud, Orb 1 stands at the head of the Urnudan stack and houses high‑ranking Urnudans. During the shipboard emergency around the World Burner, Everything Killers were activated in Orb 1, causing lethal exposure within.

A proposed one‑way percolation of information through the Wick from more theoric worlds into ours, invoked to explain minds’ apprehension of cnoöns and certain convergences across cosmi. In current discourse it is described as ever‑present but only noticed when it produces conscious perceptions, with scope and mechanism under debate.

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

A named speelycaptor feature mentioned alongside Eagle-Rez and DynaZoom, likely denoting image stabilization. Later cited in active use while recording aboard the Daban Urnud.

A high-resolution imaging feature associated with extramuros speelycaptors. Mentioned alongside SteadiHand and DynaZoom as grounds for restricting recording inside the Mynster; later observed in use together aboard the Daban Urnud.

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

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.

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

A named historical era in the mathic world associated with Cartasian principles and a shared liturgy practiced across the maths. It is generally understood to end at the Rebirth and is followed by the Praxic Age.

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.

Hemn Spaces (configuration spaces) are an abstract framework attributed to Saunt Hemn, formalized in the early Praxic Age. They are not physical locations but coordinate spaces in which any point encodes the complete state of a system, enabling theors to model systems—and even the cosmos—as worldtracks through such spaces.

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

A 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.

The current Gan (a title akin to admiral) aboard the Daban Urnud; a senior Urnudan strategic leader who meets with Fraa Jad and later addresses mourners and co‑signs a peace accord during opening ceremonies in Orb Four.

The Core is the long, rotating service trunk running up the middle of the Orbstack aboard the Daban Urnud, linking bearing chambers to the Nexi where orb stacks connect. It serves as a transit way and access corridor controlled by large ball valves.

An older Sæcular host and Heritor of the Caravansery of Elkhazg; also seen as a philanthropic delegate among the Arbran delegation aboard Daban Urnud.

A senior tactical commander (ranked Prag) aboard the starship Daban Urnud. Identified as Gan Odru’s counterpart on the tactical side, she is associated with the Pedestal and is active in directing ship responses around Arbre.

A long‑lived complex of financial interests referred to as "the Lineage" that appears to control or administer properties such as Elkhazg and Ecba across centuries. In current accounts it is represented in high‑level diplomacy by members of the Foral family.

An Arbran physician who identifies himself as “Fraa Sildanic of Rambalf” while tending to Fraa Erasmas aboard the Daban Urnud. He works alongside a Laterran doctor with Jules Verne Durand interpreting.

A formal aut observed to mark the death of an avout within the mathic tradition.

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

A term used in the mathic world to describe someone—typically an avout—who has been formally called out for praxic work or urgent purposes. In current usage it is closely associated with the Voco rite and with mass departures organized under a Convox.

The fourth edition of an in-world reference work, cited as "THE DICTIONARY, 4th edition, A.R. 3000." It is quoted for headwords such as "sline," "Gardan's Steelyard," "Terrible Events," "Peregrin," and "Requiem," presenting numbered senses, period labels, and usage notes.

A designated field cell formed at the Concent of Saunt Tredegarh and led operationally by Lio. After a covert approach that assembled the Cold Black Mirror and anchored to the Daban Urnud’s rubble shield, members are subsequently recovered by Urnudan medics and reconnected with Arbran aid.

A major historical hinge dividing the Old Mathic Age from the Praxic Age, commonly dated to around -500. It is characterized by the opening of the maths’ gates and the dispersal of the avout into the Sæcular world, sparking a flowering of theorics, culture, and exploration.

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 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.

The farthest‑aft, highest‑numbered Laterran habitat sphere within the Orbstack of the starship Daban Urnud. It has no onward portal and is reached via a zenith ladder to the Core.

A Laterran-inhabited habitat sphere within the Orbstack of the starship Daban Urnud. Notable for a hospital near the portal to Orb Eleven and for intensively cultivated terraces; it serves as a staging point within the Laterran stack (Orbs Nine–Twelve).

An Urnudan living sphere within the Orbstack of the starship Daban Urnud. Identified as the highest‑numbered Urnudan orb (farthest aft) and used as a venue for opening ceremonies and diplomatic meetings.

One of the Laterran-inhabited habitat spheres within the Orbstack of the Daban Urnud. It links by sealable portals to neighboring Laterran orbs and forms part of the Laterran stack (Orbs Nine–Twelve).

One of the Laterran-inhabited habitat spheres within the Orbstack of the Daban Urnud. It connects to Orb Ten by a sealable portal and forms part of the Laterran stack (Orbs Nine–Twelve).

A named feature within the temple complex at Orithena, closely associated with Provener; "analemma" is also a drawn curve invoked by Fraa Orolo. Visitors later reported detecting a planet‑side signal in this form, which a Laterran linguist interpreted as indicating Ecba.

An active dowment‑house at the Concent of Saunt Tredegarh that hosts a themed messal during the ongoing Convox. It is identified as the venue of the Plurality of Worlds messal.

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.

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

A 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 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.

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.

Hedron is the colloquial name for a large icosahedral alien craft orbiting the world. Its visible features suggest a pusher-plate nuclear-pulse system for translation, while recent observations show it slewing without thrusters, consistent with internal momentum wheels.

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 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 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.

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 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.

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

A messal is a small, formal dinner among avout at the Concent of Saunt Tredegarh, typically capped at seven participants and held in private rooms. During the Convox, senior hosts curate participants and topics; some messals have served as influential working sessions.

A term in mathic sources for a numbered series of historical crises late in the Praxic Age, later regarded as precursors or warnings of the Terrible Events; much is obscure due to poor record preservation.

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.

An ancient geometric tiling-and-path challenge of Orithena: played on a decagonal plaza using seven molded tile shapes, each bearing a shallow groove. The goal is to pave the Decagon while tracing a single continuous groove from one vertex to its opposite, passing across every tile.

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.

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

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

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. Following a covert boarding, internal explosions wrecked the assembly and it is now believed disabled.

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.

Kelx is a religious faith (also a term for its arks) named from Orth for "Triangle Place" and centered on a triadic cosmology of the Condemned Man, the Magistrate, and the Innocent. Recent accounts describe a shipboard ark's sermon, a Kelx-run clinic, and activity in Old Mahsht including a mission hostel and Kelx-coordinated transport.

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

A 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 historic imperial city and seat of the Bazian Empire, celebrated for its monuments, roads, armies, library, and the Ark of Baz; remembered for its sack as the Fall of Baz. Its legacy endures in the Bazian religious tradition and in cultural references preserved by mathic exhibits.

A historical label for number-worshippers expelled from the Orithenan tradition by Diax; in current speech it can also mean a zealous admirer or patron, depending on context.

A legendary or apocryphal mathic order said to operate on a ten-thousand-year cycle, often invoked as shorthand for a completely isolated causal domain. Its existence is disputed and it is generally treated as illustrative rather than historical.

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 coordinated salvo of two hundred small missiles from sites around Arbre, timed to slip behind the Daban Urnud’s line of sight. The launches lofted balloons, radar-chaff, and mixed payloads to low orbit to mask covert rendezvous and assembly under cover.

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.

A monumental building at the Concent of Saunt Edhar, invoked as a familiar measure of size by an Edharian avout while viewing the excavation at Orithena.

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.
