Helena wakes from a recovered memory of Luc Holdfast on the Alchemy Tower roof during the war. Luc is gaunt, smoking opium, and clinging to the Holdfast belief that good must triumph because Orion and the Principates won through faith. Helena argues that war is not so simple and pleads to help Luc, but Luc recoils from Helena’s touch, leaving Helena with the painful realization that Luc was badly damaged and unreachable even before Helena’s captivity.

Still longing for Luc, Helena reflects on Holdfast pyromancy, alchemisation, and the mythology surrounding Orion, Sol, and early alchemical writings. Helena then forces herself to explore Spirefell’s darker lower floors despite Helena’s fear of shadows. A waiting necrothrall reminds Helena that Ferron monitors Helena’s every movement, but Helena continues until Helena overhears Ferron arguing with Atreus Ferron, Ferron’s dead father occupying Crowther’s corpse.

Atreus tries to threaten Ferron with disinheritance and the High Necromancer’s displeasure, but Ferron dismisses Atreus as powerless because Atreus lacks iron resonance in the borrowed body. Ferron uses the iron in Spirefell to drag Atreus away and orders Atreus out, revealing both the hostility within the Ferron family and the terrifying extent of Ferron’s control over the house. The sight makes Helena understand that Spirefell’s ironwork is not just decorative but an active prison.

Back in Helena’s room, Helena tries to focus on finding Ferron’s weakness and provoking Ferron into killing Helena. Ferron arrives early and forces Helena to swallow a tablet, then uses vivimancy to alter Helena’s physiology so Helena’s emotions become distant and inaccessible. Ferron explains that the war-developed tablets preserve otherwise temporary physiological transmutations, and he says the purpose is to acclimate Helena to the house so Ferron does not have to escort Helena constantly.

Emotionally numbed, Helena can move through the dark without panic and begins investigating Ferron instead of reacting to him. Helena discovers a hidden preserved eye encased in glass high in Helena’s room, confirming that Ferron has been watching Helena through reanimated body parts. Ferron explains that reanimating small parts is easier than controlling full thralls, while Helena studies Ferron’s unnerving necromantic skill, questions whether Ferron is a homunculus, examines Ferron’s tarnished silver ring, and realizes Ferron’s power still does not make sense.

Helena uses the tablet’s effects to explore further and overhears Aurelia complaining that Ferron has altered the house for Helena, including reshaping the foyer banisters into iron bars to prevent Helena from jumping. The next morning, all of Helena’s suppressed fear, grief, and anger return violently, leaving Helena sick and despairing. When Ferron next takes Helena out, Helena manages the dark hallway by touch and memory, proving that Ferron’s experiment has partially acclimated Helena even as it deepens Helena’s suffering.
