Agatha prepares to cast a killing spell on Eusia using a piece of flesh from her own thigh. As she readies herself at the edge of a magical pool, Imogen explains to a worried Theodore that their existing bond prevents Eusia from forcibly creating a new, stronger connection without a helper. Imogen then submerges herself in the pool to witness the spell’s effect from below.
Sinking deep into the water, Imogen discovers the withered, gray body of her mother, Ligea, still barely alive, kept so by a web of pulsating veins connected to the pool walls that siphon her life force. Imogen is struck by the resemblance to her own face. Realizing that Eusia has been draining Ligea to sustain her own existence and grow her power, Imogen is filled with a new, blistering resolve to kill Eusia herself. Overcome with pity for her mother’s tortured state, Imogen kisses Ligea’s cheek and drives her dagger through her ribs, piercing her barely beating heart.
On the surface, Agatha is too weak to perform the spell. When Lachlan pulls her from the water before she can complete it, she screams in agony and collapses. As this happens, Halla confronts Theodore, accusing him of not understanding the desperation for power that drives women like her mother and Imogen.
Soon after, Imogen emerges from the pool. To spare Agatha further distress, she lies and claims the pool was empty except for the veins. Later, in the castle’s blighted garden, she confesses to Theodore that she found her mother’s body and mercy-killed her. As Imogen breaks down, Theodore comforts her. Using his own power, he causes a single purple wildflower to grow from the dead earth and tells her that Anthemoessa’s wildflowers were a gift from Panos to Ligea when she took her crown. Imogen feels betrayed by Halla, assuming that Halla—knowing Imogen’s intention to kill Eusia before she murdered her father Nemea—told Nivala, prompting Nivala to travel to travel to Anthemoessa and take Eusia to safety.
As the group boards their warship, the Eleuthios, Imogen commands the tentacled sea creature made of Eusia’s organs to move out of their path. Once on deck, Theodore is met by Aleka and Markis, who present the official order for the execution of Chancellor Eftan Zervas. Markis reveals they found written schemes proving Eftan intended to use Varya to conquer Leucosia. Lachlan argues for imprisonment over execution.
Eftan is brought before them, weak and ill. He spits at Imogen’s feet before requesting a noble death at Theodore’s hand. As Theodore prepares to swing the sword, Imogen warns him that he will regret the act for the rest of his life. Taking her words to heart, Theodore commutes the sentence and instead banishes Eftan to the island prison of Mav Petra, off the coast of Seraf, asking Imogen as its queen to accept him there. She agrees. He then orders Halla confined to her cabin under guard and prohibited from his stateroom. He sets course for Della, where they will restock supplies before heading to Obelia to confront Empress Nivala, then retreats inside with Imogen, Agatha, and Lachlan.
Safely in Theodore’s stateroom, Agatha rebukes Imogen’s guilt over her abduction, explaining that the empress had to beat and drug her to maintain control, which suggests a more powerful Siren like Imogen would have been impossible to capture. Later, Theodore takes Imogen to the netting at the ship’s bowsprit to study magic from books he has stolen.
He tells her that, in Della, they will obtain a severing draught—a magical potion—from a Mage Seer to break Imogen’s bond with Eusia. He reads from a text explaining that successful spellcraft requires not just components like flesh and blood, but also the caster’s focused intention. His key insight is that since Eusia’s bond is a spelled version of the Siren bond, breaking it may require both a draught and a spell together. The conversation about their impossible future leads to a passionate kiss.
Upon arriving at Kardinia, an island of Della, Imogen has a vision of Eusia aboard the empress’s ship, confirming she is on her way to Obelia. Imogen and Theodore go ashore and find the Mage Seer’s ancient tower. Inside, they discover the Mage is a desiccated, withered woman who lives among swarms of insects. She reveals that she was the one who guided Nemea toward Eusia’s service.
After tasting a payment of Theodore’s flesh, she identifies him as a descendant of the Great God Panos. When she tastes a drop of Imogen’s blood, she recognizes her as Ligea’s daughter and reveals Eusia’s goal to combine the powers of a Goddess, a queen, and a Mage. Imogen counters that she already possesses all three. She then uses her power to seize control of the Mage’s insect swarm, though Eusia simultaneously drains her power so she cannot release the lure herself—Theodore refuses to strike her unconscious to break it. While the Mage is helpless, they take multiple vials of severing draught and flee. As they go, they hear the Mage scream, apparently consumed by her own insects.
Back on the Eleuthios, the group discusses their plan. Agatha is still too physically and emotionally traumatized to perform the killing spell on Eusia. Lachlan affirms that Halla, who is still devoted to Eusia, cannot be trusted with the task.
With no other viable options, Theodore volunteers to cast the spell himself. Imogen objects, terrified of what using that kind of dark magic will do to him and the suffering it will cause. Theodore remains resolute, convinced it is the only way to save Imogen from having to sacrifice herself. Reluctantly, Imogen agrees to teach him the spell.
During a tense dinner, Halla states that her marriage contract with Theodore must be consummated before they arrive in Obelia to placate her mother, the empress. Imogen stoically agrees that a contract must be honored. Theodore has already failed to cast the killing spell three nights in a row, leaving him ill and exhausted. After Halla whispers to Theodore and kisses his cheek—witnessed by Imogen, who feels her power rising—the others leave.
Theodore insists on trying once more. Guided by Imogen, he successfully performs the spell on a caged rat. The magical backlash hits him with excruciating pain, which Imogen helps him endure. The relief and hope of their success leads to a sexual encounter. However, their moment is shattered when Halla knocks on the locked door. The harsh reality of his duty to Halla and their impossible situation overwhelms Imogen, and she flees by climbing out the stateroom window.
Imogen’s discovery of her mother, Ligea, reveals the literal, physical horror that underpins The Corrupting Nature of Power. Submerged in the magical pool, Imogen finds Ligea’s body actively being consumed, kept in a state of living torment as a web of veins siphons her life force to sustain Eusia. This macabre tableau makes the abstract cost of power concrete; Eusia does not merely defeat her enemies, she absorbs them, feeding on their vitality to fuel her own ambition. Her choice to kill Ligea contrasts her reasons for killing her father Nemea. Here, she does it as an act of mercy, while she slayed Nemea as an act of revenge. However, both directly represent a severing from her past and the predetermined path for her life, emphasizing her desire for self-determination and agency as well her capacity to be both vengeful and empathetic. Both Ligea and the Mage Seer—a “dried-up insect” of a woman whose body is a desiccated husk—also reinforce the narrative’s focus on literal representations of the impact of magic and quests for power. Their physical degradation is a direct consequence of proximity to Eusia’s parasitic power.
The failed attempt to cast the killing spell explores the limits of physical sacrifice and The Reclamation of Bodily Autonomy. Agatha, having already been used as a pawn and vessel by the empress, attempts to reclaim her agency by offering a piece of her own thigh for the spell. This act of self-mutilation is a desperate bid to turn her body from a site of violation into a weapon of retribution. However, her body, still ravaged by trauma, fails her. Her collapse signifies that reclaiming autonomy requires process of healing that cannot be rushed; her body remembers the trauma inflicted upon it, and that memory is stronger than her resolve. Theodore’s subsequent decision to take her place reframes the nature of sacrifice. Where Agatha’s offering is born of trauma, his is a deliberate choice to endure a corrupting force to protect someone else. His repeated failures and the agonizing backlash from his final success demonstrate that even for a god-king, dark magic inflicts a deep physical and spiritual toll. His admission that after the pain, magic “feels good” introduces a seductive element, hinting at why figures like Eusia are drawn to this power despite its corrupting influence.
Theodore’s choice to spare Eftan Zervas demonstrates an evolution in his understanding of justice and kingship, one where he’s guided away from his growing emotional impulse by Imogen, who understands the impact of these violent instincts on oneself. Presented with the order for his former mentor’s execution, Theodore confronts the brutal, pragmatic form of rule Eftan represents—a philosophy that justifies treachery and murder in service of power. Eftan’s request for a noble death at Theodore’s hand is a final manipulation, an attempt to validate this worldview by framing his execution as an honorable end. However, Imogen’s quiet but firm warning that “[a] piece of you will regret it” forces Theodore to consider the long-term spiritual wound such an act would inflict (244). By commuting the sentence to banishment, Theodore rejects the cycle of retributive violence that defines his world. He chooses to bear the political risk of keeping a traitor alive rather than the personal corruption of becoming an executioner. This act also highlights his trust in Imogen, as he banishes Eftan to her jurisdiction, grounding a major political decision in their personal alliance.
The characters’ understanding of power shifts in these chapters, moving from a binary opposition—Gods’ power versus magic—to a more complex, synthesized model. Aboard the Eleuthios, Theodore theorizes that breaking Eusia’s spelled bond requires both a magical severing draught and a spell, acknowledging the two systems as interconnected forces. This insight is expanded by the Mage Seer of Della, who reveals Eusia’s ultimately plots to achieve a trinity of power by becoming “The Goddess, the queen, and the Mage” (274). This revelation moves the conflict beyond a simple war for a throne to a metaphysical battle over the ultimate form of power. Imogen’s immediate, defiant response—that she already possesses all three facets of power—is a moment of self-actualization. She stops seeing herself as a fractured collection of inherited abilities and instead claims a unified, autonomous identity, leading to a final confrontation between two beings who embody this complete form of power.
The fraught, clandestine interactions between Imogen and Theodore highlight how their relationship functions as Love as an Act of Resistance against the rigid demands of their public duties. Their moments of connection are stolen in hidden spaces—the grotto, the netting of a bowsprit, the locked stateroom—reinforcing the transgressive nature of their bond in a world of political maneuvering. This tension between personal desires and political obligations is a key element of the romantasy genre, generating the yearning and angst that defines their dynamic. The conflict comes to a head after Theodore successfully casts the killing spell. They partake in a desperate, frantic sexual encounter born of relief and the momentary illusion of hope. The illusion is shattered by Halla’s knock on the door, a harsh intrusion of reality that reminds them of Theodore’s unbreakable marriage contract and Imogen’s impossible future. Imogen’s flight out the window is a potent symbol of their situation: Their love offers no easy escape, only fleeting moments of rebellion before they are forced back into their separate, conflicting roles.
