, a 10-day observance held only once every year, decade, century, or millennium, depending on the frequency with which a given group of avout is allowed to interact with the Sæcular world. Concents are therefore slow to change - unlike the rest of Arbre, which goes through many cycles of booms and busts.

Interaction between the avout and the Sæcular world is not, however, limited to Apert. The secular power may "Evoke," or remove from the concent, members of the avout, when needed to address pressing scientific ("theorical") issues facing Sæculars. Such removal is one of many "Auts" (ritual acts) performed on certain occasions – much like rituals or sacrament

 Edhar (Saunt, abbreviated St., is a corruption of the ancient word savant and is a title bestowed on influential intellectuals of the past). His primary teacher, Orolo, discovers that an alien spacecraft is orbiting Arbre — a fact that the Sæcular Power attempts to cover up. Orolo secretly observes the alien ship with a video camera which is prohibited by Cartasian Discipline. Erasmas is unaware of the content of Orolo's research until he deciphers it after Orolo is banished in a rite called Anathem as the result of his possession and use of proscribed technology within the concent.

The law of the Second New Revised Book of Discipline that governs the lives of the avout at the time of the narration – which bans the avout from owning anything but two pieces of clothing and a sphere with multiple uses, and bans them from using or even knowing how to use any technology but paper and pen – was developed in response to the third large-scale plundering of concents by the Sæacular world, which itself was initiated due to the Sæcular belief that certain avout, especially of the Millenarian Maths, had developed a praxis (technology) that required nothing more than the mind, and was (depending on a specific avout's inclination or area of study) able to effectively change the past ("the Rhetors") or the future ("the Incantors")

s, in which information may only flow in one direction. This premise, which is discussed in an appendix (a "Calca"), is key to understanding later events in the book.

Several months pass, and Erasmas falls in love with Suur Ala, another avout at Saunt Edhar. Immediately after this, the Sæcular Power removes (Evokes) her along with several other avout, and Erasmas expects never to see her again. Erasmas, still upset about Orolo’s banishment, throws himself into his work. The presence of the alien ship soon becomes an open secret among many of the avout at St. Edhar. Several weeks later, a laser shines down from the ship and illuminates the Millenarian Math of Saunt Edhar. Now that the aliens have shown themselves openly, the Sæcular Power evokes many avout from Saunt Edhar, this time including Erasmas himself, along with one Millenarian - Fraa Jad.

Erasmas and the rest of the avout are told to travel to the concent of Saunt Tredegarh, two thousand miles away. But Erasmas and some like-minded avout also desire to find Orolo first, and subsequently enlist a few extramuros (non-avout) volunteers (including Erasmas' half-sister Cord) on an unauthorized journey to Bly's Butte, where they think Orolo has traveled to continue his astronomical observations. Upon arriving there they discover that Orolo had already left for a destination unknown. Fraa Jad urges Erasmas to continue his search for Orolo towards the North (over the frozen pole of Arbre), suggesting that Orolo has valuable information about the aliens. Erasmas agrees and sets off with just three companions to pursue Orolo, while the others turn back and head to Tredegarh. Along the way, they determine that Orolo's destination is likely to be the isolated former concent of Orithena, far in the opposite hemisphere of Arbre. They also acquire another companion named Yulassetar Crade, a tough wilderness guide with skills important for their trek. By this time, the aliens have come to be known as the Geometers because of a graphical proof of Pythagoras' Theorem (which in the alternate world of the book is referred to as Adrakhones' Theorem

) seen inscribed on the hull of their ship.

After a dangerous journey over the planet's frozen pole, Erasmas and his comrades eventually arrive at a concent-like establishment called Orithena, and reunite with Fraa Orolo. Orolo holds discussions with Erasmas about the nature of the cosmos and consciousness, and how he believes that the Geometers are not simply from another planet, but from another cosmos which is influenced by Arbre. During the discussions between Orolo and Erasmas, a small spacecraft lands on Orithena. A female Geometer is on board, but dead of a recent gunshot wound.

 Durand, known to them as Zh'vaern. He explains that the Geometers are experiencing internal conflict between two factions. The currently ruling faction intends to attack and raid Arbre for its resources, while the opposing faction favors open negotiation. Jules Durand offers to assist the avout of Arbre in resisting the ruling faction of the Geometers, believing that they can bring the situation to a peaceful conclusion.

On discovering that their infiltration had been uncovered, the Geometers attack Saunt Tredegarh, and the Anti-Swarm is started (an organized dispersal of the avout throughout the planet, amongst regular society). Erasmas and several of his old and new avout friends are taken to a distant sanctuary, where they receive training for a mission to board the Geometers' ship — the Daban Urnud — and disable its weaponry. They are launched into space, unknowingly bringing with them "Everything Killers"

 destroy the ship's main weapon, perishing in the attack. In one Narrative, Fraa Jad leads Erasmas into the command center of the "Daban Urnud", where it emerges that the Millenarian avout of one thousand years in the past may have used their "incanting" powers to summon the ship to their cosmos from another parallel (or higher?) one. In yet another Narrative, Jad opens a door into a protected area and, upon being attacked, triggers the Everything Killers; Erasmas dies and most people on the Daban Urnud starship are killed.

In the final Narrative (the one that continues ahead) Erasmas awakens in a hospital on the starship to the perplexing news that Fraa Jad had died soon after their launch, contradicting his obvious presence and memories up to that point. It remains unclear which (or how many) of these contradictory narratives is real, and what may have happened in different worldtracks that have crossed and overlapped. However, Fraa Jad had hinted that the Incanters (and possibly Rhetors) were capable of operating simultaneously in parallel universes, so Jad is likely to have survived in other world lines.

Erasmas discovers that the Geometers have brought up a high-powered delegation from Arbre, including Ala and his sister Cord. A funeral ceremony for those lost on both sides of the attack forms part of the signing of a peace treaty between the "aliens" and the Arbrans. On Arbre itself, the Sæcular Powers and the avout have agreed to cooperate as equal powers. The people of Arbre inaugurate a second historical "Reconstitution", revising many of the rules that had restricted the work and lifestyle of the avout (which included drug-induced sterility). Erasmas and friends set about the task of rebuilding Orithena as a new temple dedicated to Saunt Orolo. The closing scene is a rousing double wedding, with Erasmas marrying Ala, and his sister Cord marrying Yulasseter Crade.

The "Discipline"

In the novel, avout follow a life path called the Discipline, sometimes referred to as Cartasian Discipline, after Saunt Cartas, the founder of the mathic world. It is a set of rules governing what is (and is not) allowed for avout to know and/or do, and was codified centuries before the time of the story in the Second New Revised Book of Discipline.

Chief among these is that the avout are separated, both mentally and literally, from the Sæculum, or outside world. There are different levels of separation. For example, within a concent, there are different terms of residency. There are 1-, 10-, 100-, and 1,000-year orders. Each of these celebrates "Apert", a festival opening the concent to the outside world and allowing the flow of information between them, on an interval determined by that number. For example, a 10-year order would celebrate Apert once every ten years, remaining isolated otherwise. Likewise, a 100-year order would only celebrate Apert every hundred years, and a 1,000-year order once every 1,000 years. It is an essential part of this that at any time an order celebrates Apert, all orders below it also celebrate Apert. For example, a Millenarian (1,000-year) order would celebrate in the year 3000. Because 3000 is also a multiple of 100, 10, and 1, Centenarian, Decenarian, and Unarian orders would also celebrate. Exceptions to this rule include "hierarchs" (those who administer the concent) who are required to confer with the Sæcular Power on decisions of weight.

The main secondary aspect of the Discipline is that the avout are allowed to own only their "bolt, chord, and sphere". These objects are made with "newmatter" (matter made with a modified atomic structure to be more versatile), and can be made to alter their shape, texture and other physical properties without the use of tools or other outside technologies. The bolt is a length of newmatter fabric and is used as clothing; the chord is a newmatter rope used to secure the bolt; and the sphere is a newmatter balloon of adjustable size, shape and hardness, and serves as a multipurpose tool.

There are several restrictions governing, for example, the use of "sequencing" (genetic engineering
