Quick Facts

Short Summary

Diago, a young man from the conquered island nation of Suus, survives the deadly Labyrinth and discovers that reality was split into three worlds—Res, Obiteum, and Luceum—to contain the Concurrence, a godlike entity that culls all life every few centuries. Adopting the identities Vis Telimus, Deaglán, and Siamun, he navigates political conspiracies in the Catenan Republic, trains with druids in Luceum, and infiltrates the tomb-city of Duat to assassinate the catatonic ruler Ka. Alongside allies from all three worlds, Diago must decide how far he will go—raising an undead army, sacrificing friends, and embracing the burden of leadership—to prevent the next Cataclysm and break the cycle of violence.

Full Summary

Part One: The Labyrinth and Obiteum (Chapters 1–11)

The book opens with a dry description of the eight-tier Catenan Rankings (Chapter 1), a rigid hierarchy based on the transfer of Will from lower ranks to higher ones. The narrative then plunges into Chapter I, where Vis escapes the Labyrinth with his brother Caeror, who is trapped in the parallel world of Obiteum. Caeror explains that the Rending split reality into three realms during an ancient war against the Concurrence. The Concurrence won on Obiteum and now triggers a Cataclysm every three centuries; the last occurred 302 years ago. Vis learns he is a copy created by the Gate, and Caeror declares they must kill a god—Ka—to prevent the next Cataclysm.

Vis wakes on a boat in Luceum (Chapter II) with his left arm amputated. A druid named Cian helps him escape pursuers, but Cian is later beheaded by King Fiachra's warriors (Chapter VIII). Vis fakes his death and adopts the name Deaglán, finding refuge with a farming family. Meanwhile, in Res, Vis (as Catenicus) attends the funeral of his friend Callidus (Chapter III) and learns that his missing arm may cost him rank. He resolves to undergo the Will-ceding ceremony at the Aurora Columnae (Chapter X), where his adoptive father Ulciscor and stepmother Lanistia are revealed as Anguis agents. Lanistia attacks Vis during the ceremony, and the chapter ends with her capture.

Part Two: Duat and the Instruction Blade (Chapters 12–22)

Caeror mentors Vis in Qabr, a bleak tomb community on the border of Duat. Vis learns to use Instruction Blades—daggers that can imbue and control others. He successfully commands a volunteer named Tash but fails to exert control at a distance (Chapter XI). A terrifying encounter with the golden door to Duat triggers traumatic flashbacks (Chapter XII). In Res, Vis (now going by the name Siamun in Duat) meets Relucia, who introduces a scarred teleporting man as his new Anguis contact (Chapter XIV). He secretly visits Lanistia in prison, learning that a voice controlled her attack (Chapter XV). Emissa ambushes Vis and warns him that a blood test will expose his anomalous Will; she offers to cede his Will temporarily, but he refuses (Chapter XVI). Vis enlists Eidhin to blackmail a senator for a pass and a blacksmith for a prosthetic arm.

Part Three: Luceum and the Druidic World (Chapters 13, 17, 25, etc.)

Deaglán's story in Luceum continues as he trains with the warrior Tara at Loch Traenala, learning the nasceann battle-fever (Chapter XXXVIII). He faces trial by combat against Gallchobhar, the King's Champion, and is saved when a spirit speaks through him (Chapter XXVIII). Deaglán is sent to Fornax, a sunken city that rises at "the time between times" (Chapter LXII). Inside a grand building, an Aurora Columnae triggers an attack by silver statues; Deaglán uses Harmonics to command one and escapes with a silver arm (Chapter LXV). At the siege of Caer Áras, Tara rescues Deaglán but is captured; Gallchobhar stabs Deaglán and throws him into a lake (Chapter LXXIV). Deaglán's father resurrects him with a life-giving medallion, and Deaglán kills Gallchobhar in single combat (Chapter LXXVI). Lir, now dead, trains Deaglán in the mental realm, and Deaglán reunites with his father, who reveals the cycle of Cataclysms and the true nature of the Gate (Chapter LXI).

Part Four: Political Intrigue in Caten (Chapters 19–31, 33–35, 48–58)

In Res, Vis (as Catenicus) undergoes Placement, becoming a Sextus after ceding his Will to Eidhin (Chapter XIX). He meets the scarred man Ostius, who trains him in Adoption—the rare ability to sense and take others' Will (Chapter XX). To prove his worth despite his missing arm, Vis competes in a chariot race (Chapter XXVIII–XXX), winning and forcing his rival to acknowledge him. He investigates the Iudicium with Emissa, discovering that corrupt senators colluded in the attack that killed his friend Callidus (Chapter XXXIII). Vis becomes embroiled in a civil war as the Military faction rebels; he kills senators alongside the alupi Diago (Chapter LV). Ostius reveals Vis is bait to draw out Ka (Chapter LVII). Caten falls into chaos, and Vis, Emissa, and Aequa escape.

Part Five: The Endgame (Chapters 59–81)

Vis reunites with his resurrected father, who explains that the Cataclysm recurs because of the Concurrence, and that Suus discovered ancient weapons (Chapter LIX–LX). In Duat, Siamun (Vis) infiltrates the Temple of Ka with Netiqret's help, learns to control iunctii, and ultimately stabs Ka through the heart (Chapter LXXVIII). Deaglán awakens in Caer Áras after the battle, buries his father, and confronts Ruarc, who reveals himself to be Caeror from another world (Chapter LXXIX). Vis, now leading an undead army of 80,000 iunctii raised from the Necropolis, embraces his revived mother and sister (Chapter LXXX). The book concludes with non-narrative chapters: a character list (Chapter 82), a location glossary (Chapter 83), and maps of the Catenan Republic and Solivagus (Chapter 84).

Main Characters

• Diago (Vis Telimus Catenicus) – The protagonist, a young man from Suus who assumes multiple identities to navigate a three-world conspiracy and prevent the recurring Cataclysm.
• Caeror Telimus – Vis's brother, trapped in Obiteum, who mentors him in using Instruction Blades and reveals the Concurrence's threat.
• Emissa Corenius – A senator's daughter and former friend of Vis who initially betrays him but later aids his investigation into the Iudicium and the Cataclysm.
• Ka – The catatonic ruler of Duat and leader of the Concurrence, targeted for assassination to prevent the next Cataclysm.
• Tara ap Rónán – A disinherited princess and warrior in Luceum who trains Deaglán and challenges Gallchobhar, embodying sacrifice.
• Ulciscor Telimus – Vis's adoptive father and an Anguis agent who initially treats Vis as a tool but later forms an equal alliance.

Themes

• The Burden of Leadership – Vis repeatedly sacrifices personal safety and morality to protect others, culminating in awakening an undead army and confronting Ka.
• Identity and Transformation – Vis adopts multiple names across worlds, reflecting his struggle to reconcile past trauma with evolving purpose.
• Systemic Oppression and Resistance – The Catenan Hierarchy's Will-based caste system and the druidic Old Ways are shown as corrupt structures that protagonists rebel against.
• Truth and Deception – Secrets about the Cataclysm, the Iudicium, and the Anguis conspiracy drive the plot, forcing characters to choose between trust and manipulation.
• Cycles of Violence and Redemption – The Cataclysm recurs every few centuries due to the Concurrence; characters like Vis and Tara break personal cycles of revenge through acts of mercy.

Symbols

• Aurora Columnae – A glowing obelisk that measures Will capacity and serves as a gate between worlds, central to Vis's Placement ceremony and the Fornax trial.
• Instruction Blades – Daggers used to imbue and control others, representing the power of coercion and the moral cost of overriding free will.
• Crook and Flail – Ancient weapons found in Qabr that destroy anything except their wielder when activated by blood, symbolizing righteous leadership and destructive duty.
• The Silver Arm – An artificial limb forged from a Fornax sentinel that Vis imbues, representing both physical loss and reclaimed agency through Will.

Ending Overview

The climax spans three realms. In Duat, Siamun (Vis) penetrates the Pyramid of Ka, uses the crook and flail to fight through Gleaners, and stabs the catatonic Ka through the heart, likely ending the Concurrence's immediate threat. In Luceum, Deaglán, resurrected by his father's medallion, kills Gallchobhar in single combat, breaks the siege of Caer Áras, and confronts Ruarc (who is revealed as Caeror from another world). In Res, Vis performs a Cascade in the Necropolis, awakening 80,000 iunctii as an undead army, and is reunited with his mother and sister. The book closes with non-narrative chapters cataloguing characters, locations, and maps, leaving threads for potential sequel: the Concurrence's larger plans, the fate of the three worlds, and the true nature of the Gate remain partially unexplored.
