Dianna tortures Julian, son of the werewolf chief, to locate his father, Caleb. He throws blame back, saying that Dianna’s alliance with Samkiel caused Gabby’s death. Dianna kills him, summoning Caleb and the pack. Caleb claims that the wolves cannot defy Kaden. Dianna drinks his blood through a counter-curse Camilla made and sees a memory of Caleb meeting Tobias: The wolves were searching for something as preparations built toward the equinox. Dianna questions Caleb, but he knows little beyond the fact that Tobias wants the Book of Azrael in time for the equinox. Dianna reveals that she knows the wolves have been tracking her and Samkiel for Kaden and then executes Caleb and the surviving pack.

A voice in Samkiel’s head warns that time is running out. He meets Logan, who insists that Dianna’s violence is grief, not nature. They speak of Gabby and Neverra and admit that they feel afraid. Logan notices Samkiel’s headaches and isolation without Dianna.

Edgar wakes. Questioned, he explains that Dianna spared him after seeing a photo of his late wife. He knows almost nothing about Kaden beyond what Tobias tells him. He confesses that he told Dianna that love for Samkiel drives her fury. A concussive boom shatters the moment, and three blue lights streak across the sky. Samkiel accuses Vincent of summoning The Hand; Vincent denies it.

As a raven, Dianna infiltrates Rashearim and listens to Leviathan and Elianna of the Council of Hadrameil. Cameron speaks to the bird, unaware that it is Dianna; Xavier mocks him. They wonder why Samkiel has not called them. When Cameron asks after the bird’s family, the word “dead” tolls in Dianna’s mind. Imogen arrives, and Dianna flies off to wait. Hours later, she uses Camilla’s instructions (one drop of Samkiel’s blood to enter, two to open a vortex, three to return) to breach the chamber. The place floods her with memories of Samkiel. She steals some texts (she is later revealed to have been searching for Drake’s map), but Cameron, Xavier, and Imogen confront her with weapons drawn.

Cameron recognizes Dianna’s scent from a previous episode in which she disguised herself as Imogen to help Samkiel infiltrate the celestial council (described in The Book of Azrael). Barbs turn to combat: Xavier identifies Dianna as an Ig’Morruthen, and The Hand attacks as one. Dianna floors Imogen, cracking the celestial’s skull. She recalls a warning from Samkiel that she cannot win head-on and adapts. Reading Xavier and Cameron’s tandem rhythm, she slices Cameron open and hurls him over a balcony. Xavier dives to save him. Imogen rallies and swears that Dianna will die here. Dianna drops two beads of Samkiel’s blood, opens the vortex, and disappears.

Dianna stumbles into the prison of Roccurem, a “fate” who can see everything that is happening and could happen, and realizes that the cell is made of Roccurem himself. He greets the “Queen of Yejedin,” says that even gods failed to kill him, and asks how she intends to try. Dianna attacks but then halts as a star flickers behind him. She blames him for not warning her about Gabby’s death. Roccurem says that Gabby dies in every possible future and that Dianna’s ascension requires the loss; however, this inevitability does not mean that Dianna is to blame. Dianna shatters the prison and binds Roccurem to her service until Kaden dies. He warns her that she already knows why she cannot find Kaden: He hides beyond sealed realms. Roccurem then says that the One True King is coming and that time is running out. Dianna takes him and leaves.

Samkiel visits Cameron in the medical wing with Vincent and Logan. Cameron mutters that his attacker was Samkiel’s “girlfriend.” Samkiel reels at the thought of Dianna laying waste to Rashearim. Xavier vows to kill her; Samkiel forbids it, claiming that this vengeful Dianna is not her true self. He says that she saved him from his despair after Rashearim fell, when no one else could. Vincent disputes the comparison, but Samkiel answers that he has killed far more than Dianna.

Imogen arrives as the council’s new advisor and reports that Dianna freed Roccurem. Samkiel leaves Cameron to heal and heads to Rashearim with Vincent and Imogen.

Dianna threatens a stylist for an unkind remark about Gabby. Roccurem, in a glamoured human form and going by the name “Reggie,” counsels restraint. Dianna stops a truck, kidnaps the driver (Elijah), and interrogates him about Kaden. She loses patience and kills him, ignoring Roccurem’s warnings. Roccurem says that Samkiel has returned to Rashearim with Imogen, and jealousy cuts through Dianna’s grief. She asks how Roccurem was locked away. He reveals a prophecy about two children—one born of a celestial, one of a god—destined to rule and save the worlds. Only Samkiel survived. The Moirai (fates) revealed the prophecy too early, leading to the other child’s death, and the gods slaughtered the fates. However, Unir hid Roccurem, both safeguarding and imprisoning him. Roccurem denies that fate controls choice. He warns that Dianna must make a decision. Kaden then appears.

Dianna launches fire at Kaden, but he turns out to be a projection, which the flames pass through. She sends Roccurem away and trades barbs with Kaden. Kaden shows her the obsidian-lined mirrors that he uses to spy on her and needles her about Samkiel and Imogen’s betrothal. Dianna rejects the idea of their relationship, saying that she asked Samkiel about it, but the mirrored images that Kaden shows of Imogen close to and comforting Samkiel hurt. She wants Samkiel happy, yet jealousy festers. Kaden claims that Samkiel does not need her but that he himself does. He offers to bring Gabby back. Dianna refuses, saying that she will not damn her sister to another life of pain. She then leaves, grief-stricken and heartsick.

Roccurem urges Dianna to end the self-isolation she has adopted since her confrontation with Kaden. Dianna confesses that after she became an Ig’Morruthen, only Gabby pulled her back from bloodlust by threatening to leave. She grieves the one person she believes truly loved her. Roccurem argues that she is wrong. He explains that betrothals among the gods serve order, not love; if a ruler cannot find their “soul tie,” they must bind to another. He insists that love for Samkiel did not kill Gabby. Dianna explodes, and he withdraws, promising to help.

Roccurem tells Camilla that Dianna’s wrath is grief sharpened by Kaden’s words. He explains that the gods once forbade the creation of Ig’Morruthens after forging them as weapons to end a war. Warning of Dianna’s abilities, he says that a worse threat than Kaden approaches.

Later, Camilla delivers her new device, shaking before Dianna’s massive wyvern form, and begs for time. Dianna studies her without visible emotion.

Samkiel and Imogen handle a petty complaint to keep the peace and then return to Silver City. Roccurem appears, and Samkiel holds steel to his throat. However, Roccurem remains calm and says that Dianna intends to besiege the city. He shows memories of Dianna and Samkiel’s tenderness and explains that love deepens Dianna’s guilt. Kaden exploited that guilt by revealing Samkiel’s betrothal. Roccurem tells Samkiel to let Dianna into the city, trap her, and give her a family for the best possible outcome.

Cameron and Xavier discuss the likely battle with the council. They expect the council to demand Dianna’s death and Samkiel to refuse. Dianna interrupts and trades insults with them, saying that she’s “stalling” until Samkiel arrives. Cameron goads her, and Dianna smirks, promising disaster.

Imogen urges Samkiel to host a gathering to build alliances before the council acts. They find Cameron with a broken nose, which he says Dianna caused.

Samkiel, Imogen, Logan, Xavier, and Cameron confront Dianna, who is holding a waitress at knifepoint. Samkiel crushes “Dianna’s” throat, revealing her to be Camilla under a glamor. Under torture, Camilla admits that Dianna is seeking a map from Drake’s mansion (it is later revealed that Dianna knows Kaden is using tunnels in Drake’s estate to transport materials, and she hopes the map will lead her to Yejedin). Camilla also offers a sleeping spell to trap Dianna. Samkiel accepts and then orders the city evacuated as he prepares a distraction for Dianna.

Samkiel takes Imogen with him through the empty city, arriving at a skyscraper called the guild. Imogen recalls a vow The Hand made to bring Dianna back because Samkiel loves and needs her. After the two separate to sweep the building, Samkiel suddenly appears behind Imogen, making odd remarks about the map. As Imogen realizes this Samkiel is Dianna in disguise, the real Samkiel appears, but not before Dianna seizes Imogen by the throat.

Dianna demands the map. Samkiel and Imogen lie, implying a rekindled romance. Samkiel also claims that the sprinkler system carries poison. Thus, when Dianna nearly kills Imogen, Samkiel causes water to rain down, and Dianna releases her hostage and flees. Samkiel explains to Imogen that he needed proof that the real Dianna remains beneath the rage.

Samkiel catches up to Dianna near the room that contains Drake’s map. He destroys the map just as she tries to reach it, and her fury ignites the city. She dissolves into smoke, but Samkiel tracks her through the “inbetween,” a place his father told him about that exists on the borders of existence. She threatens to tear out his heart. He tells her to do it; it is hers anyway. He kisses her, and she kisses back, which triggers the sleeping spell.

Dianna wakes in chains and finds Samkiel waiting for her. She accuses him of poisoning her. He answers that the spell did not harm her and only worked because she kissed him back. He removes her ring, the home of the forsaken blade, and explains that he has assigned Xavier and Cameron as guards while he rebuilds the city; they will then go to Rahsearim, Dianna included. She tries to drive him away with cruel words, but he refuses to leave. Samkiel is certain that the Dianna he loves still exists.
