In the garden, Headmaster Silas confirms the Decennial is a ritual sacrifice and that the deaths of Nick, Liza, Georgia, and Tristan are real. He explains that the soul vow traps the nominees; anyone who forfeits is eliminated and fed to the Ether. Josie breaks down while the others react with disbelief. Wren confronts Silas about erasing the memories of the students, but he justifies the sacrifices as necessary and “insignificant.”
Remembering Nick’s death, Masika lunges at Silas, but August restrains her. Silas tells them they must continue to compete or face elimination. As they realize only one of them can survive, despair sets in. Silas announces the third trial will begin immediately.
Silas leads the eight remaining nominees into the woods as snow begins to fall. In a clearing, eight stone arches stand in a ring. He explains that each arch is a portal to a separate illusion trial where they must find an elixir, dismantle the illusion, and return. He vanishes.
After a tense exchange with Masika, Irene enters her portal first. Carter, Josie, August, Wren, and Masika follow into their own portals. Olivier and Emilio share a final moment together before passing separately through the last two arches.
Irene lands in a snow-blasted tundra, her connection to Mateo severed. She finds a teacup holding a black elixir, drinks it, and is imprisoned inside a transparent glass cage. A vision of her mother appears and taunts her for choosing emotional isolation over connection. Dark water rises around her legs, and her magic fails. As she drowns, Irene faces up to her pattern of pushing people away. Refusing to yield to the trial, she hardens her resolve to survive and win at any cost.
In the snow, Emilio finds Josie’s corpse, which disintegrates into ash, proving failure means real death. On a frozen lake, he finds his own elixir and drinks it. He enters an illusion of his childhood home, where his parents plead for him to stay. He resists and breaks the illusion. He returns to the snow, where a monstrous replica of Olivier mocks him for cowardice. Emilio runs for his arch, but the replica tackles him and drives a dagger into his stomach.
Inside a mountain, Masika finds a chamber where Housemasters Birdie and Russo reveal they belong to a resistance. Catherine, Masika’s former friend, arrives and exposes Silas’s past: He is a Corrupted Soul who overthrew the original Headmaster and warped the Ether. Those he banished formed the Demien Order, which seek to counteract Silas.
August appears, and the resistance forces him to admit he is an undercover agent for the Order. Feeling betrayed, Masika attacks him. A stray spell triggers a collapse. As the chamber crumbles, Catherine, Birdie, and Russo vanish. August tries to save Masika, but she is trapped.
Irene returns to the Bonestrod dining hall. She finds Wren unharmed and sees August with a wounded shoulder. Nearby, Olivier cradles a badly wounded Emilio. Wren reports that Carter and Josie have been eliminated. Headmaster Silas arrives and ignores Olivier’s pleas to heal Emilio, stating he will not heal trial injuries. He declares Masika eliminated, saying she must have died in the collapse.
Silas announces the final trial will occur the next day and departs. The survivors sit with their losses, bound by the rules.
Olivier carries Emilio to his bedroom and searches for a way to heal him. Emilio stops him and asks him to lie down with him. Olivier holds him close and speaks about his mortal life in the late 1800s, admitting he did not feel truly alive until he met Emilio. Emilio grows weaker, slipping in and out of consciousness. Olivier promises to stay awake but falls asleep from exhaustion with Emilio in his arms.
Emilio finds himself in a sunlit valley. He feels weightless and hears a loved one calling from a distance. He lets go of fear and pain. The valley softens into brightness, and he drifts into the quiet beyond, accepting his fate.
That night, Irene summons Mateo and confronts him about the Decennial’s true nature. He admits he knew. Irene declares her intent to join the Demien Order to get revenge on Silas. Mateo outlines their plan: She must win the Decennial, become an Ascended, and serve as their spy within Blackwood. He warns this path will demand her humanity. Irene accepts the role, and Mateo promises they will carry out the plan together.
These chapters mark the novel’s pivotal narrative turn, as its mystery-plot arc is increasingly resolved. The revelation that the Decennial is a ritualistic sacrifice, a truth delivered by Headmaster Silas with pragmatism, confirms that Blackwood’s order is built upon deception and violence. Silas’s justification frames the slaughter of 11 students as a “small, insignificant sacrifice worth preserving the order of the afterlife” (385), confirming him as a tyrant who manipulates utilitarian logic to sanctify mass murder. This initial shock is immediately complicated by the counter-narrative presented to Masika, which exposes Silas as a usurper and repositions the Demien Order as a resistance born from his tyranny. This recontextualization is crucial, as it completes the collapse of the Silas’s false good-versus-evil framework, the construction and destruction of which shapes the book’s structural arc. This conflict is no longer a clear-cut battle between the academy and its enemies but a multi-faceted power struggle between corrupt universal factions, signaling that the narrative will open out into a subsequent series. This resolves the theme of Adolescent Rule-Breaking as a Transition into the Adult World as, in an environment where traditional authority is illegitimate, they must rely on their own moral judgements. Irene’s decision to join the Demiens as a spy exemplifies this shift: Her choice is a pragmatic maneuver to survive and dismantle a system she now knows is rotten to its core.
As before, the third trial tests the nominees psychologically, this time confronting them with illusions who challenge their self-perceptions and coping mechanisms. Irene’s trial challenges her pattern of self-isolation: A vision of her mother taunts her that she is trapped in a “cage of your own making” (399), a consequence of her deliberate emotional detachment. Irene’s response is to double down her strength and self-reliance hardening her resolve. As this leads to her completion of the trial, the novel suggests that the test is of the nominee’s ability to see the benefits of their coping strategies and practice self-compassion in the face of criticism. Similarly, Emilio’s trial targets his vulnerability. Faced with a monstrous replica of Olivier that mocks his softness, Emilio refuses to disown his capacity for love and empathy, recognizing these qualities as his “act of defiance” against a brutal world. For a young adult audience, this paradoxical trial models the ability to withstand excessive criticism, positing that “negative” personality traits have their corresponding positive effects.
The introduction of permanent, unhealable injury is a significant shift in the Pain and Healing motif, signified by Emilio’s potentially fatal stab wound. Silas’s cold refusal to intervene, stating that injuries “must heal naturally” (425), underscores the finality of this new reality and solidifies his role as an arbiter of death rather than a protector of students. The motif extends beyond the physical; Olivier’s frantic powerlessness as he watches Emilio die is a form of emotional torment that strips away his characteristic cleverness and control. His grief is as palpable and destructive as Emilio’s physical wound. This grounding in mortal consequence elevates the emotional weight of the narrative, encouraging empathy for the characters and asking questions about the nature of death. The invulnerability and magical solutions of the earlier chapters have been replaced by a brutal reality where pain is real, loss is permanent, and survival is not guaranteed. This shift in tone signals a darkening mood that will continue to the end of the novel.
