Baltiel prepares to lead the first human landing on Nod, leaving Siri Skai in charge of the orbital module. Although the mission is officially a research substitute for halted terraforming, Baltiel privately wants the historic first step and hopes to preserve a record of Nod before future human colonists destroy its biosphere. He reflects on the planet’s strange biology, its possible technological value, and the worsening war reports from Earth.

As Baltiel, Erma Lante, Gav Lortisse, and Kalveen Rani head for the shuttle, Rani warns that Senkovi has sent nonsensical meteorological data and may be having trouble. Baltiel contacts Senkovi but chooses not to investigate fully because he refuses to miss the launch window. During descent, the Aegean begins transmitting gibberish around Senkovi’s voice, and Senkovi admits that his modified octopodes have escaped their virtual training environment, infiltrated ship systems, and forced him to shut the Aegean down and reboot it.

The narrative shifts to Senkovi aboard the darkened Aegean. Senkovi realizes that his secret expansion of the octopus project, including forty-three modified subjects, has outgrown his control: Salome has used remotes destructively, Paul has fought him for the communications suite, and the other octopi have learned from one another. Instead of evacuating with Han, Poullister, and Maylem, Senkovi stays in a suit to save as many tanks as possible with battery-powered heaters and pumps while the ship purges and restarts.

On Nod, Baltiel steps onto the salt marsh but initially feels anticlimax because his suit separates him from the alien world. He observes the marsh’s radial creatures, fliers, and shell-bearing tortoise-like grazers before entering the habitat. Then Skai reports a strange signal from Earth spreading across every frequency; her transmission breaks into panic, static, and silence, and soon the habitat, suits, shuttle, and communications all shut down.

Baltiel and the ground crew infer that a decades-old attack from Earth has disabled their systems. They remove helmets inside the habitat to conserve air, jury-rig suit tanks, and try to restore pumps and communications, but the habitat remains a ticking clock. Baltiel checks the shuttle and finds it dead and inaccessible, while Rani builds a crude transmitter/receiver that hears no response from the module, the Aegean, or Senkovi’s evacuated shuttle.

With breathable air dwindling, Baltiel volunteers to test Nod’s atmosphere. He removes his helmet outside, experiences the planet’s unfamiliar smells and sounds directly, and survives despite discomfort, proving that the crew can breathe unaided for a time. When Baltiel returns, Rani’s receiver picks up Senkovi’s voice from the rebooted Aegean; because Nod’s air will keep the ground team alive long enough, Baltiel realizes rescue may still be possible and takes the transmitter to answer Senkovi.
