The Archive Undying

Many city-states were once ruled by artificial intelligences. AIs were treated as gods; human archivists served as their priests. Over the centuries, many AIs became corrupted and died.

The Harbor, a group of human-run city-states, creates ENGINES cobbled together from pieces of dead AIs. An ENGINE is a mech that requires both an archive and a relic to pilot it. Relics are humans who are interfaced with an AI at the time of its corruption. An archive is a copy of an AI's memories; however, an archive is not sentient and has no self-coherence, requiring a human relic to direct it.

Iterate Fractal is an AI and god of the city-state Khuon Mo. It is corrupted and destroys the city. Sunai is an archivist who becomes a relic as Iterate Fractal dies. He finds that after his resurrection, he is unable to age or be killed. After Iterate Fractal's death, the Harbor is unable to take complete control of Khuon Mo. They share the city with business magnate Madam Wei and her Ginger Company.

Seventeen years later, Sunai works as a salvager. He frequently indulges in alcohol, drugs, and casual sex while hiding from the Harbor. He is hired to join the crew of the salvage rig “Third Scrap”. Sunai has sex with Veyadi Lut, the rig's owner. Veyadi is one of Iterate Fractal's former archivists; Sunai worries that this indiscretion will expose his identity.

Sunai, Veyadi, and their crew explore the ruins of Chom Dan, where Veyadi served as an archivist after Iterate Fractal's death. Nearby, they discover a shrine that is home to an unknown AI. When Sunai tries to interact with the AI, it embeds itself into Sunai's mind and becomes his passenger.

Sunai reunites with Imaru, a former business partner and friend, who advises him on a potential job in Khuon Mo. The Harbor has finally found a way to create an ENGINE from Iterate Fractal's remains. Imaru wants to kill the ENGINE. Sunai and Veyadi join Imaru's rig “Never Once”, which is backed by Madam Wei. Wei plans to kill Iterate Fractal's relics whenever they are discovered; this is to prevent the Harbor from operating the ENGINE and gaining control of the city.

The party confronts Iterate Fractal's ENGINE. The ENGINE is also known as the Maw, as it tends to kill its relics accidentally. The Maw tries to assimilate Sunai, but fails and flees. The party reaches Khuon Mo. They meet Ruhi, one of Sunai's former lovers and a liaison for the Harbor. Sunai learns that Veyadi is also relic of Iterate Fractal. They are the only two surviving relics that can operate the Maw. Sunai realizes that there is no relic controlling the Maw, meaning that it is practically an independent AI. (The Harbor has kept this fact secret, as it goes against their stated anti-AI beliefs).

Imaru helps the Maw merge with Sunai. This kicks the passenger out of Sunai's brain and into Veyadi. The passenger reveals that it is the cause of all AI corruption; it was created by AI themselves as a check against their power. Ruhi has been working with the passenger; he attacks the city and tries to destroy Iterate Fractal's remaining archives. Veyadi and Sunai fight against Ruhi; Sunai bites out his throat and kills him.

Sunai and Veyadi weave the passenger into Ruhi's corpse, imprisoning it. They are both joined to the Maw, two relics sharing one ENGINE while retaining most of their individuality. They hope to keep Khuon Mo safe as the Harbor and remaining AI city-states jockey for control.

According to a review from Kirkus, the story contains interludes narrated by two different AIs, one of which is supposedly dead. These interludes are told in the second person. Additionally, "it's not always possible to tell who is narrating or experiencing various moments of the story, as consciousnesses merge and only incompletely separate."^[1]
