In this chapter, Gordon detects an anomalous NMR signal that appears to be a message from the future, prompting a secretive collaboration with Claudia Zinnes to decode it. Despite initial skepticism and exhaustion, Gordon becomes convinced of the signal's reality and significance, leading to a breakthrough that confirms the message's existence. The chapter explores Gordon's personal struggles balancing his scientific obsession with his relationships and health.

This chapter explores the nuanced role of the Eschaton, a powerful agency that intervenes in human affairs not always destructively but through subtle, secretive 'nudges' to maintain causality and prevent violations. The narrative then shifts to a military setting where an aging Admiral grapples with incomplete intelligence and prepares for conflict, while a Procurator named Vassily contemplates covertly investigating a suspected radical diplomat aboard the fleet. These plotlines intertwine themes of secrecy, trust, and the ethical ambiguity of intervention and surveillance.

Abigail, long held in a state of developmental inhibition due to her mother's psychosis, is finally allowed to mature and is entrusted with leading the Gentian family business amid financial decline. The family seeks a partnership with Ludmilla Marcellin, who plans an ambitious interstellar exploration project involving a fleet of near-light-speed ramscoop ships each piloted by clones of herself, called shatterlings, to explore and colonize the galaxy over centuries. The chapter explores the technological and philosophical limits imposed by physics, particularly the impossibility of faster-than-light travel and causality violations, while highlighting themes of legacy, human expansion, and the use of virtual reality as a medium for political and personal interaction.
