Enoch reflects on his experience with a highly advanced and realistic rifle range built into the station, which simulates hunting dangerous and alien beasts. He contemplates the nature of reality versus illusion in these simulations, the primal human instinct for combat and killing, and the alien perspective on human aggression and war. The chapter ends with Enoch reviewing the results of his latest simulated hunt, realizing he missed a critical shot.

The chapter follows a young man who meticulously studies and rehearses the behavior and protocols of a highway patrolman through a detailed tape-recorded simulation. After preparing himself in uniform and adopting the patrolman's persona, he pursues a yellow Ford pick-up truck on a highway, engaging in a tense cat-and-mouse chase that culminates in the truck evading capture by slipping off the highway and into a bar's parking lot. Throughout, the young man is guided by a disembodied voice through a phone, suggesting a controlled or artificial environment.

This chapter, 'Part I: Lies,' explores the fragmented and often illusory nature of life in 2021 through the perspectives of several characters—Mrs. Hanson, Lottie, Shrimp, and January. It juxtaposes mundane domestic scenes, such as watching television and shopping in a museum-like supermarket, with deeper emotional undercurrents of longing, disconnection, and the search for meaning amid artificiality. The narrative also introduces a clandestine political cell, hinting at broader social unrest and personal vulnerability.

Mastir Bascule undertakes a harrowing ascent inside a vast shaft using a balloon tethered by plastic tubing and guided by lammergeiers, battling physical exhaustion, cold, hallucinations, and the threat of a pursuing rocket. Despite deteriorating equipment and psychological strain, he perseveres upward, haunted by symbolic numbers and faint encouragement from Ergates. Concurrently, a tense confrontation unfolds between Quolier and Asura, followed by Oncaterius's combat within a simulated reality, culminating in a surreal rescue by a mammoth-mounted group, blending themes of identity, entrapment, and survival.

The chapter centers on a centennial celebration at Wrinkle Rock, an asteroid home for elderly and machine-stored humans, commemorating the discovery of the Gateway asteroid and the dawn of human interstellar travel using ancient Heechee spaceships. It explores the experience of disembodied minds interacting in immersive simulated realities and contrasts their rapid cognition with the slower pace of living humans. The narrative culminates in the narrator consulting an advanced AI, Albert, to analyze suspicious military maneuvers, communication embargoes, and surveillance by General Cassata, highlighting themes of restricted freedom and escalating tension.

The chapter explores complex scientific and philosophical ideas, beginning with Albert's explanation of higher-dimensional space required by supersymmetry and the challenges of perceiving curled-up dimensions. It then delves into the provisional nature of scientific truth and the fluidity of identity through program merging, while also portraying Robin's emotional struggles and the solace found in a luxurious virtual party. Finally, the narrative examines the immersive simulated reality experienced by the narrator and Essie, highlighting tensions around reality, emotional vulnerability, and the human need for connection within artificial environments.
