Two weeks into an undercover mission, Tisaanah poses as an enslaved woman named Roza in the estate of Lord Farimov, a Threllian nobleman. Her magic has been weak since an earlier battle, and a Fey illusion disguising her appearance is beginning to fail, revealing her Fragmented skin—with pale patches marking her as a member of the Valtain order of magic wielders. She awaits a meeting between Farimov and two Fey emissaries—General Iajqa Sai’Ess and her second, Nessiath Vareid. The meeting grows complicated when Lord and Lady Zorokov—a powerful Threllian couple whose household once murdered hundreds of enslaved people in retaliation for Tisaanah’s past actions—arrive unexpectedly. Farimov presents the Fey with a glass orb containing swirling mist that triggers a deep instinctive response in Tisaanah. When her illusion visibly flickers, she manipulates Lord Farimov into taking the Fey on a tour of the castle to get them out of the room. Alone with an enslaved woman named Melina, she touches the orb; it vanishes, embedding intricate gold patterns into her palm. Her disguise collapses entirely. She reveals her identity to Melina, sends a remote, magical signal to her Fey ally Ishqa to rescue her, arms herself, and persuades the terrified Melina to lead them through the servants’ tunnels, explaining that she cannot use her magic in the castle because it is surrounded by magic-suppressing wards.

To hold onto his sanity in Ilyzath—a semi-sentient white stone prison that erases every mark its captives make—Max obsessively redraws the same three shapes on the floor. The prison torments him with hallucinations and whispered provocations. Eyeless Syrizen guards arrive to escort him to Queen Nura on the war-ravaged mainland of Ara. Soldiers stare at Max, seeming to recognize him, though he doesn’t know why. The guard at his back voices desperate hope that he might be their savior. Max is almost relieved to go; he has a plan.

Tisaanah and Melina rush through the servants’ tunnels, pursued by guards. At the exit, a young guard named Markus—in love with Melina—blocks their path. Melina asks him to flee with them, but he instead restrains Melina, prompting Tisaanah to kill him. Outside, they are surrounded by the Zorokovs, their guards, and the Fey emissaries. Nessiath identifies the gold mark as the artifact. Zorokov orders Melina’s throat cut. Guards nearly sever Tisaanah’s hand while trying to take the artifact; she forces out the last of her magic to fight back. Mid-battle, she glimpses a vision through Max’s eyes of his white cell and the figures he repeatedly draws. Just as the soldiers overpower her and are about to chop off her hand, Ishqa arrives and shields her. General Iajqa pleads with Ishqa to return for his son’s sake, causing Ishqa a moment of indecision before he flies away in silence with Tisaanah.

Aefe—a Fey named Reshaye who was forced to spend 500 years as a disembodied spirit used as a weapon by the humans, recently given a physical body by the Fey King Caduan—suffers acutely in her new solitary existence. Rare dream-connections to Tisaanah and Max are quickly overwhelmed by a traumatic memory of Ishqa abandoning her. She wakes screaming and attacks a maid. Caduan intervenes and calms her. His advisors press him to deploy Aefe as a weapon in the war; he refuses, calling it as monstrous as the humans who once weaponized her. Hours later, rather than endure her loneliness, Aefe agrees to accompany him on an undisclosed errand.

In a basement research chamber in the Towers of Ara, Queen Nura and her researcher Vardir show Max his three-shape drawing, then tattoo additional Stratagrams onto his palms to suppress his magic before beginning an experiment. Consumed by pain, Max experiences fragmented visions of his past. He briefly seizes control of the energy being channeled through him—vital to his escape plan—but a psychic connection to Tisaanah, who is witnessing Melina’s murder, destroys his focus. He loses consciousness. Nura revives him; Vardir blames the failure on Max’s own mental barriers. As Max is escorted back to Ilyzath, a shadow creature appears and tears his guard apart.

At the rebel encampment, Sammerin heals Tisaanah’s nearly severed hand while she reflects on the rebellion’s fragile victories. Serel and Filias arrive with crushing news: After 11 failed attempts and the death of an experienced fighter, Filias is ending all rescue missions to Ilyzath. Tisaanah offers to go alone; they refuse, citing the danger to the rebellion if she were captured. Filias calls her a liability, which enrages her, and she confronts them and Sammerin for giving up on the man who saved them all. Once her colleagues leave, she smashes the bowl of raspberries they left as a guilt offering.

Caduan leads Aefe to a private forest training ring and presents her with two curved black blades matching the ones she once wielded. Holding them stirs an overwhelming memory of her former identity, quickly crushed by memories of being used as a weapon by the humans. She attacks him. As they spar, his commentary on her past self drives her fury higher until she backs him against the wall with her blade at his throat, demanding to know why he brought her back and screaming that she wanted to die. He offers himself as a target. She pulls the blade away, declares that she hates him, and is interrupted by a panicked guard.

Caduan leads Aefe to a room where a Fey soldier recovered from Nura’s experimentation lies dying. Caduan’s second-in-command, Meajqa—who resembles Ishqa and has a wing hacked off at the joint—watches in grim silence as Caduan mercifully ends the soldier’s suffering. An advisor argues that they must use all available power, glancing pointedly at Aefe. A messenger then reports that Tisaanah has stolen the artifact, aided by Ishqa. Meajqa, Ishqa’s son, turns away without speaking. Aefe privately realizes she could track Tisaanah through their shared connection but says nothing. Caduan orders General Iajqa to retrieve the artifact and declares that he will create more shades.

The shade that killed his guard, whose name was Vivian, turns on Max. He dodges, injuring his foot, and kills the creature with a spear, but not before the act of gazing at its featureless face triggers vivid memories of a little girl surrounded by flames and a teen boy with broken glasses. He convinces another guard, Merah, to free him from his restraints, but a larger shade kills her as soon as she does so. Max fights the shade until it runs away. Alone and unbound, Max sees more shades along the shoreline, decimating Nura’s army. He sees a clear path to the docks and is about to escape his imprisonment when he spots a young soldier named Moth losing a fight with another shade. He abandons his escape, kills the creature using fire magic channeled through his spear, and carries the gravely wounded Moth to a healer. Before losing consciousness, Moth reveals that he knows Max, though Max—whose memory has been damaged by his time in Ilyzath—doesn’t remember him. Moth tells Max that Tisaanah is looking for him and that people would still follow him. Max attempts to flee again but is pinned by a shade. A man appears and kills the shade, rescuing Max, who recognizes the man as his brother, Brayan. Brayan confronts Queen Nura, demanding to know why his brother is imprisoned in Ilyzath.

Max wakes in the Towers to find Brayan and Nura present. The sight of his brother unlocks 15 years of memory: his parents and siblings; his home, called Korvius; his choice to leave home to join the military; and Nura. Gaps remain—he knows his family is gone but not how, and he knows he ended the Great Ryvenai War but not why he was imprisoned for it. Brayan demands Nura release Max; she refuses. When Brayan positions himself between Max and the guards, Nura correctly points out that his loyalty to Ara prevents him from raising his blade against her soldiers—and he does not. Recognizing that Brayan will be killed if he fights, Max leaves without resisting. Later, Nura visits his cell and tells him Vardir believes his own mind is blocking his power. When Max asks what happened between them, she says only that she loved his family before leaving.

Aefe dreams of Niraja, where she and a younger Caduan were ambushed by humans. As the memory freezes, she glimpses something like hidden rage in his expression. A magical cataclysm then tears through the world, pulling her simultaneously into her own room, Max’s white cell, and Tisaanah’s tent. She follows an irresistible call through the castle and into the forest, finding Caduan barely upright from exhaustion after creating shades. As they walk back, he explains that due to Ishqa’s lie, he believed she had died in Niraja. He tells her that he thought of her every day for 500 years. Aefe tells him she can sense Tisaanah’s location through their connection. He uses this information.

Tisaanah buries herself in work to avoid her grief. That night, she finds Sammerin on a ridge, and they speak honestly. He confirms that he argued against ending Max’s rescue missions. She confesses her deepest fear: that Max believes she abandoned him, particularly since she never answered when he once spoke of a shared future. Sammerin tells her that Max’s belief in her is unbreakable. Later, a dream of Max dissolves into a magical cataclysm that briefly places Tisaanah inside his white cell, where she screams his name with no voice. Ishqa wakes her, examines the wayfinder, and suddenly panics—telling her they must leave immediately as screaming erupts outside.

In a vision, Max is pulled into a raw, deeper layer of the world where he briefly feels a familiar presence calling to him. He wakes in his cell certain that something cataclysmic has broken in the world. Desperate attempts at magic only burn his hands as the Stratagrams redirect his magic back into himself. Sensing that Ilyzath itself has desires, he proposes a bargain: He will carry a fragment of the prison into the world and return when summoned if it lets him go. Ilyzath agrees, marks his palm, and opens a door. He walks out unopposed to find Brayan waiting on the shore with a boat.

Tisaanah’s rebel encampment burns as Iajqa’s lieutenant, Nessiath, leads Fey and Threllian soldiers through each tent. Ishqa urges Tisaanah to flee; she refuses. Seeing Filias facing the attackers and Sammerin helping the wounded, she walks into the open to confront Nessiath directly, hoping to draw the soldiers’ focus from her people. She negotiates a brief pause before Threllian soldiers ambush her, dislocating her shoulder and overwhelming her failing magic. She kills them with a hidden blade. As Nessiath charges, Sammerin wraps his arms around Tisaanah and uses a drawn Stratagram to transport them away.

Unable to sleep, Aefe wanders into a tavern where Meajqa invites her to drink. He describes the months Nura spent experimenting on him while he was conscious and helpless—at the cost of his ability to shift his wings. Aefe recognizes the helplessness. He tells her that while Caduan’s war is fought for all Fey, his vengeance is for her specifically. Six days later, Aefe seeks Caduan out and finds him explaining the Lejaras—mythical pools of deep magic—to his advisors. He tells her that she alone is the key to finding them and that he needs her. The phrase mirrors what her human captors once said. She refuses, hurls a quill at his face, and storms out of Ela’Dar entirely.

On the boat, Max tells Brayan the full story of his escape. Brayan reveals that he has been coming to Ilyzath every day trying to gain access and outlines a plan: Sail to the island of Sarilla, then charter a ship north to Threll and travel to his home in Besrith. Max discloses that Stratagrams cover his arms and have largely suppressed his magic. On Sarilla, they attract unwanted attention as strangers. Brayan leads them to a farmhouse belonging to Sella—whom Max quickly identifies as Brayan’s former fiancée.

Tisaanah and Sammerin land in a forest south of the burning encampment. Sammerin commits to staying with her. Ishqa arrives at sunrise and reports that many rebels escaped. He gives Tisaanah a potion to partially mask the wayfinder, then explains that it is a compass for locating the Lejaras, which Caduan seeks to weaponize against humanity. He insists that neither Caduan nor Nura can be allowed to find them. Tisaanah agrees—though privately, her sole motivation is the hope that such power could free Max from Ilyzath. Ishqa says he knows someone who can help and directs them north.

Aefe wanders to the ruins of the House of Obsidian, her ancestral home. Memories of her former life return—her identity as a member of the ruling Teirness family, her father’s contempt, the obliterated room of her sister Orscheid. She stands at the edge of a chasm and contemplates throwing herself in. Caduan follows her. In the ruined throne room, he shows her a vision of the past: Caduan confronted her father to prevent war, her mother failed to act, and Orscheid, to protect Caduan, cut their father’s throat, only to be killed by his dying counterattack. Caduan explains that the subsequent war destroyed all Fey houses. He asks—without commanding—for her help finding the Lejaras and building a world free of human cruelty. She asks if their plan involves killing Tisaanah and Maxantarius, and he hesitantly agrees. When she asks whether they will kill the Aran queen and he answers without hesitation that they will, Aefe commits.
