Summary

Erasmus is studying to become a theor in the Math of Saunt Edhar under Fraa Orolo, a theor in cosmology. Erasmus lives roughly three thousand years after human civilization on Arbre quickly shot up the tech tree to weapons of mass destruction and programmatic nucleosynthesis (i.e. alchemy) so fast that civilization collapsed. Science and its application has since been regulated by The Powers That Be (i.e. government) which restrict knowledge to within the Maths. The Maths are informationally isolated (insert "hermetically sealed" pun here) monastaries in which theors curate and safeguard history and technological blueprints.

One day, Orolo is banished from the Math, presumably for illegal astronomy.

Erasmus and his fellow students work to determine why Orolo was ejected from the Math.

Their studies help them make full use of the observation of an spaceship performing an orbital plane change maneuver while in line of sight between Arbre and the Sun. The Powers that Be call various theors, including Erasmus' girlfriend, to work outside the Math, presumably to never return. When the ship acknowledges the existence of the Maths by shining laser light on, among others, Saunt Edhar, The Powers that Be call Erasmus and many others to travel to a Convox located on the other side of Arbre to study the ship and decide what actions to take.

Erasmus travels with others until he decides to search for where Fraa Orolo went, believing Orolo had special knowledge of the ship. After a nearby clue proves fruitless, Jad, a millenarian, convinces Erasmus to search for Orolo at a Math-like archeological dig named Ekba on the other side of the planet. After a dangerous journey across the north pole in order to illegally cross borders, Erasmus finds Orolo at Ekba.

Orolo informs Erasmus that the details of his astronomical observations were not as significant as Orolo's conclusion that the ship was not of Arbre. Orolo tells Erasmus of a many-worlds theory of consciousness that he believes allows humans to think with limited amounts of nerve tissue by leveraging crosstalk between parallel worlds that are similar but not quite the same; Orolo hypothesizes that the millenarians developed a praxis (i.e. technology) that enabled them to send and receive information from other worlds. Erasmus is worried that Orolo is talking about Incanters, a mythical group of theors that could change the future around which talk is prohibited by the Inquisition; the Incanters are contrasted in earlier parts of the book with the Rhetors, who have the power to change the past. Orolo's dialogue with Erasmus on the many-worlds (i.e. "polycosmic") topic is abruptly terminated when he is killed by the heat from a pyroclastic flow from an Ekba volcano that was triggered into activity by an orbital kinetic strike by the ship after a human-shaped alien escaped to land dead at the archeological site.

Erasmus then attends Convox after being retrieved by The Powers that Be. Liquids in vials retrieved by Orolo from the dead alien during the chaos of the Ekba evacuation are analyzed and found to contain alien blood made of atoms with nuclei not natural to Arbre. Unlike artificial nuclei produced by ancient Arbre nucleosynthesis technology in order to achieve superior materials science ends (e.g. high tensile strength low density fabrics), the nuclei in an alien parachute had no extraordinarily useful properties. Erasmus is debriefed during a public interview and is then assigned as assistant to a prominent theor Doin named Fraa Lodogir who, in turn, is assigned to a "Many Worlds" messel (i.e. think tank workshop). Erasmus and some of his Edharian colleagues, including the mysterious millenarian Fraa Jad, discuss with representatives of other Maths the possibility that the aliens are from another cosmos.

The history of polycosmic theory is explained at various sessions of the messel with analogy lubrication provided by a Lorite (a theor dedicated to preventing duplicated academic effort). Orolo's theory of polycosmic crosstalk, independently predicted by him but also independently predicted by many other Edharians throughout time, is fleshed out as a fundamental property of matter that is so ubiquitous that its nature was not properly identified when quantum superposition theory was refined. However, Erasmus's doin Fraa Lodogir, argues that predictions require confirmation through experiment; polycosmic crosstalk can't be detected because its results average out to noise. Fraa Paflagon, a centinarian Edharian who was called out of Edhar shortly before Orolo was anathemitized, argues that polycosmic theory couldn't be confirmed until the aliens "down wick" traveled up to visit Arbre. A Maderite, Fraa Zh'vaern, reveals that a fraa in his mathic order discovered a polycosmic praxis that allowed him to erase a scratch on a bowl. The Messal is immediately shut down due to worries that The Powers that Be may infer that the Maderite was claiming the existence of Incanters and Rhetors.

Erasmus and company, with some hints from Fraa Jad, successfully reveal that Fraa Zh'vaern is an alien after Erasmus eats some of Zh'vaern's food and discovers his body's digestive enzymes were unable to alter the food's chemistry normally after shitting it out. Despite informationally-isolating the Messelin room with a Saunt Bucker's basket (which Zh'vaern announces is called on his world a "Faraday cage") and preparing commandos to neutralize other alien spies, Zh'vaern warns that The Pedestal, the alien faction in control of the ship, will retaliate with an orbital strike on the Convox location. Erasmus's military-minded colleague, Lio, announces the existence of an evacuation plan prepared by Erasmus's girlfriend, Ala, and helps evacuate the Convox attendees.

After some brief training, Erasmus, Jesry, Lio, Arsibalt, Jad, Sammann, and various martial artist Fraas are sent into space on some of Arbre's last orbital launch vehicles before the remaining launch facilities are rodded out of existence by the ship. They form a commando mission to disable the World Burner, a fission bomb capable of sterilizing a planet, installed on the Dabun Urnud, the alien ship. Using distraction confetti to hide their initial position and a cold dark mirror to hide their trajectory, they approach the Dabun Urnud. On the way, Jad disables a communication relay that he claimed was interfering with his control of narrative. Erasmus reveals that Jad is basically an Incanter who can communicate with many versions of himself across different branches of history.

Erasmus and company board the ship surreptitiously in two groups. One group is composed of the martial artist Fraas (members of the order of the ringing vale; "valers") who go directly to disable the World Burner and threaten to destroy the ship. The other group is composed of Erasmus, Jad, and company whose mission is to establish contact with the friendly faction on board the ship (the faction that attempted to share information at Ekba).

In one version of events, everyone died except for Erasmus and Jad, who don firefighter suits and infiltrate the command habitat. After Jad brute-forces a 4-digit PIN securing a door, a sentry detects them and Everything Killers secretly embedded in their guts by The Powers That Be activate, presumably killing everyone on the Dabun Urnud with neutron radiation.

In another version of events, Jad fails to open the door and is apprehended by less trigger-happy sentries who instead take them to meet with a powerless strategist who describes to them the history of the Dabun Urnud's various conquests across the polycosm. The strategist told them that basically the Incanters, in a panic as they were being exterminated by The Powers That Be in ancient times, summoned the Dabun Urnud.

In another version of events, Jad had died shortly after launch, the valers successfully disabled the World Burner before ultimately dying, and Erasmus with the others lost consciousness upon breathing the ship's oxygen mix and not being able to become acclimatized quickly enough. The Powers that Be threatened further action to the Dabun Urnud so the leaders of the Dabun Urnud agreed to a cease fire and peace talks (their leader in particular had nightmares of what could happen).

The book concludes following this last version of events. Erasmus attends peace talks aboard the Dabun Urnud, reunites with his sister who helped him cross the arctic, and meets the Rhetor Fraa Lodoghir who indirectly tells him in secret that Jad cannot return without undoing the success of the peace talks. Erasmus marries his girlfriend, Ala, and they found a new Math, Saunt Orolo, in a world with fewer restrictions from The Powers that Be now that technology from the mathic world escaped during the evacuation of the Convox.

Errors

  • In Part 7, Feral, following his discovery that Jesry was accompanying the Warden of Heaven to space and a discussion with Kraid on how the Warden led a religion splintered off from that of the Samblites, Erasmus realizes Orolo departed Bly's Butte the morning after laser light had shown down upon the Three Inviolates; Erasmus imagines Orolo packing up his bolt, cord, and sphere despite the fact that Orolo possessing these items at this point in time is inconsistent with how he is described leaving the Concent of Saint Erasmus: with minimal clothing following the Anathem ceremony. (pg. 439)

He had departed for the north only a couple days before we had—the morning after the lasers had shone down upon the Three Inviolates. Why would that cause him to pack up his bolt, chord, and sphere, and hurry to Ecba, of all places?
