In the aftermath of the Prison battle, Rhysand orders an injured Cassian to rest while Nesta stands with Ataraxia and the Harp still in her hands. Nesta silently apologizes to Feyre for her cruelty at Amren's apartment, and Feyre forgives her through their daemati link, easing a major rift between the sisters. The group then turns to the Harp itself, concluding that it is too dangerous to return to the Prison and too dangerous to keep near the Mask, so it must be heavily warded and stored separately.

When Rhysand questions Nesta about what she sensed from the Harp, the discussion widens into ancient history. Rhys explains the old legends of the Daglan, near-godlike tyrants who once ruled and terrorized both Fae and humans, and describes the Wild Hunt as one of their methods of control. He also recounts the story of Fionn, the first and only High King, his sword Gwydion, and his eventual betrayal, while Nesta adds what Lanthys showed her: the hound-like beasts resemble those carved in the Hewn City, and there may be a hidden fourth object in the Dread Trove. Rhys confirms that Narben was a legendary death-sword, and the conversation makes clear that Briallyn's pursuit of the Trove may be part of a much older and darker pattern.

The group next debates how to stop Briallyn. Feyre and Cassian argue that pursuing the Crown directly is too dangerous, especially after Briallyn's soldiers nearly ambushed Nesta and Cassian in the Prison, so they decide instead to strengthen alliances and prepare for war. Rhys proposes using the coming Winter Solstice celebration in the Hewn City to reassure Eris that the Night Court still supports him, and suggests that Nesta dance with him and seduce him politically. Cassian is furious at the idea, but Nesta accepts, partly out of confidence in her own strength and partly in defiance of Cassian's protectiveness. Afterward, Nesta lays Ataraxia on Rhys's desk and refuses to keep it, saying she wants no more death.

That night, Nesta continues her breathing exercises and Mind-Stilling practice in her room. Instead of spiraling, she finds that her thoughts settle, and she recognizes that healing may simply mean continuing one breath and one day at a time. This quiet scene shows that, even amid war and politics, Nesta is developing real discipline and inner steadiness.

Later, Azriel winnows Nesta and Cassian to the ruined human cottage where the Archeron sisters once lived, then leaves them alone. Walking through the decayed rooms forces Nesta to confront the poverty, shame, and bitterness of that period, from Feyre's paintings on the walls and dresser to her father's wood carvings on the mantel. With Cassian gently prompting but not pushing, Nesta admits how deeply she resented her father, how often she failed Feyre, and how she never let herself see that her father had still been trying to care for his daughters in the little ways he could. Realizing that love and weakness can coexist, Nesta takes the carved rose her father made for Elain and leaves the cottage feeling that nothing remains there but dust and bad memories. When Cassian suggests they go flying, the chapter ends on a note of release and fragile forward movement.
