Rhys brings Feyre to dinner at the House of Wind and lets her choose whether to stay. She meets Cassian, Rhys's army commander, and Azriel, his scarred, shadow-wreathed spymaster, and quickly learns that both males are informal, dangerous, and far from courtly. Mor joins them, teasing Cassian, and then Amren arrives, radiating such alien power that Feyre's instincts tell her to run. Amren immediately identifies Feyre as someone who, like herself, was born one thing and is now trapped in another body, confirming that Feyre's mortal soul now lives in an immortal form.

As the group settles into an easy, familial meal rather than a formal court gathering, Feyre begins to see how Rhys's household works. Azriel explains that his and Cassian's Siphons focus the destructive killing power of strong Illyrians into precise magic. Rhys clarifies that Cassian and Azriel are not lords, that Mor is the only titled pure-blooded noble present, and that he and the Illyrians are treated as lesser because of their bloodlines. When Feyre asks why she never saw them Under the Mountain, the group reveals that Rhys hid Velaris from Amarantha for fifty years, a success that spared the city but clearly cost all of them deeply.

To answer Feyre's questions, the Inner Circle recounts how they were forged. Cassian and Azriel explain that they are bastards from the brutal Illyrian camps, where lineage rules and females are maimed by wing-clipping to control them. Rhys then tells Feyre about his mother, an Illyrian female nearly clipped before his father recognized their mating bond and saved her, and about being sent to train in the camps as a child. There he met Cassian, later Azriel, and the three eventually allied because they were stronger, hated, and more vulnerable together than apart; during the War, Rhys's father separated them out of fear. After Rhys became High Lord, he made these four his Inner Circle, gave the old Night Court nobles the choice to accept them or leave, and defined this hidden side of his rule not as the Court of Nightmares below the mountain, but as the Court of Dreams. Amren says she accepted Rhys's offer to become his Second simply because no one had ever asked before, and Mor summarizes her own past by saying she was a dreamer born in the Court of Nightmares who escaped.

Prompted to share in return, Feyre tells them about her human life: her family's fall from wealth, her father's broken leg, and the years she spent teaching herself to hunt to keep everyone alive. Cassian immediately offers to teach her to fight, because her old skills are not enough for what is coming. Feyre hesitates, repeating the Spring Court idea that such training might look improper, but Mor sharply rejects that thinking. Mor tells Feyre that leaving the Spring Court already sent whatever message it would send, and that living by other people's opinions is suffocating. That support helps Feyre recognize Mor as the first real female friend she has had, and it helps her decide that Rhys was right to let her judge whether she could belong among them.

Feyre then openly accepts Rhys's offer to work with him, earn her keep, and help against Hybern, only to learn the decision has immediate stakes. Rhys reveals that the King of Hybern is preparing for war and wants to resurrect Jurian. The group connects that plan to recent temple massacres, the theft of Jurian's ring and finger bone after Amarantha's death, and the Attor's escape. Amren says they need answers from the Bone Carver in the Prison, and that the creature may speak to Feyre because she is an immortal with a mortal soul. Rhys decides that he and Feyre will go, and when asked, Feyre chooses the danger rather than retreat.
