Onyx Storm by Rebecca Yarros, the third book in The Empyrean series, closes on one of the most puzzling cliffhangers in modern romantasy. This Onyx Storm ending explained guide walks through what actually happens in the final chapters, separates what the book confirms from what fans are guessing, and lays out what it all means for Book 4.
Spoiler warning: This article discusses the ending of Onyx Storm in full, including major deaths, Xaden’s transformation, Violet’s second signet, and every unresolved mystery. Come back after you have finished the book.
How does Onyx Storm end? The quick answer
Onyx Storm ends with the battle of Draithus. Violet kills the venin maven Theophanie, and Xaden channels dark power to save his dragon Sgaeyl, which pushes him further into becoming venin. Violet then wakes at Riorson House with no memory of the previous twelve hours, wearing a ring and carrying a marriage blessing that says she married Xaden. Xaden is gone, four riders and six dragon eggs are missing, and Imogen tells Violet that she erased her memory because Violet asked her to. The book does not explain why.
Onyx Storm Ending Explained: Ending timeline
The final stretch runs from the fight at Draithus through the closing chapter, and it shifts between several points of view. Here is the sequence in order.
The battle of Draithus
Violet and Xaden are separated during the fight against the venin and their wyvern. Violet takes on Theophanie, a storm wielder whose power echoes that of Violet’s late mother, General Lilith Sorrengail. Xaden is drawn away by his Sage, Berwyn.
Elsewhere in the fight, Mira’s throat is cut and Brennan struggles to mend her until Sloane Mairi arrives and siphons power from Dain Aetos into Brennan Mira survives. Her presence matters later, because it means the battle was not the loss of another Sorrengail.
Imogen’s chapter and Quinn’s death
The book briefly leaves Violet and follows Imogen Cardulo and her dragon Glane. Imogen sees venin closing in on the turret where her best friend Quinn is stationed and heads there with Dain. When fire comes at them, Imogen reveals a second signet by turning her shield to stone. Imogen and Quinn kill the venin together, but Quinn is stabbed in the chest and dies in Imogen’s arms. Garrick Tavis then appears and uses his own second signet to move Imogen and Quinn’s body to safety.
Violet kills Theophanie
When her conduit shatters and Theophanie slows the storm, Violet is nearly beaten. A package from Aaric contains a marble dagger from the high priestess of Dunne’s temple in Aretia, with a note telling her to strike in the dark. Violet realizes Aaric’s signet is precognition. When shadows suddenly blanket the battlefield, Andarna returns unseen and Theophanie is distracted. Violet stabs her with the marble dagger. Stone is not supposed to kill venin, but Violet points out that Theophanie was once a high priestess of Dunne. Theophanie dies, and Violet passes out.
Xaden channels
In Xaden’s chapter, he and Sgaeyl are trapped in a net and Sgaeyl is wounded. Berwyn, whom Xaden believed he had killed at the end of Iron Flame, is there. Xaden realizes Berwyn has made another “sibling” for him, someone Xaden does not name but is stunned could have chosen this path after watching Xaden’s struggle. Commandant Panchek and his dragon are caught too. Berwyn kills Panchek’s dragon, and when he raises the same dagger toward Sgaeyl, Xaden channels. His shadows rip across the battlefield, the same ones that save Violet. Hearing Violet’s “I love you” through their bond, Xaden pulls himself back before losing himself entirely, but he is no longer a venin initiate. He asks Sgaeyl to have Tairn bring Violet to him, because he has a plan that Violet will have to agree to first.
Riorson House: the memory gap
The final chapter returns to Violet. She wakes in a courtyard at Riorson House with Imogen nearby. Brennan learns that four riders and their dragons, plus three elder riders, died in the battle, and that four riders including Garrick, along with six eggs from the hatching grounds, are missing. Xaden is presumed responsible. Violet cannot reach him through their bond, and Tairn is quiet. Andarna answers in his place and says he needs a cycle of rest.
Brennan then notices an emerald ring on Violet’s hand, made from the same kind of stone as the Blade of Aretia that Xaden keeps by his bed. A marriage blessing from the priestess of Dunne’s temple is in her pocket, and on the back is a note in Xaden’s handwriting telling her not to look for him and that something is hers now. Violet learns she was gone for twelve hours. She turns to Imogen and asks what happened to her memory. Imogen answers that she did what Violet asked.
Violet’s second signet explained
Violet’s second signet is dream-walking, a type of inntinnsic power that lets her enter other people’s dreams. She and Xaden work this out in Onyx Storm after sharing the same dream, and they realize the recurring nightmare she has had about a venin Sage is actually Xaden’s dream. Readers had seen hints of it since Iron Flame.
What the book establishes
The ability comes from her bond with Andarna, and the book treats it as dangerous. Xaden tells Violet to keep it secret because other people will see her as a threat. Violet has barely had time to test it, so its limits are unclear.
What it could mean for Book 4
It is natural to wonder whether dream-walking could let Violet reach Xaden while he sleeps. That is a theory, not a setup the novel confirms. Yarros has said in interviews that readers have seen only a fraction of what the ability can do, which suggests it will grow in importance, but the book never shows Violet using it to contact him.
Does Xaden die in Onyx Storm?
No. Xaden does not die in Onyx Storm, but he is transformed, missing, and not cured.
These are four different states, so it helps to keep them apart:
- Alive: Xaden survives the battle and leaves with Sgaeyl.
- Transformed: His channeling pushes him further into venin territory, beyond initiate status.
- Missing: He is gone when Violet wakes, and the bond between them is silent.
- Cured: The novel does not establish any cure for becoming venin, and nothing in the ending suggests he has been cured.
His last scene shows how close the line is. He clings to Violet’s love to stop channeling, which suggests his humanity is still fighting, but the text does not tell us how much of him remains. Sgaeyl, according to reviews of the final scenes, goes along with his plan reluctantly.
Why are Violet and Xaden married?
The book confirms that a marriage blessing exists, but not why Xaden wanted it.
What the text confirms
- Violet wears an emerald ring tied to the Blade of Aretia.
- She has a marriage blessing from the priestess of Dunne’s temple.
- Xaden’s handwritten note is on the back.
- Reviews describe the document as making Violet Duchess of Tyrrendor, though the exact legal wording should be confirmed against the text before publication.
What remains interpretation
Tyrrendor is the obvious political angle, since the marriage may give Violet authority over the province while Xaden is gone. Another theory holds that the marriage was part of a larger plan, perhaps to infiltrate the venin. A third reads it as a purely personal act made before a dangerous separation. The book supports none of these over the others, and the wording of the note leaves room for all of them. Some outlets also report a third line in the note referring to “he” being gone, which other summaries do not mention, so treat that as unconfirmed.

What happened during the missing 12 hours?
Violet lost twelve hours of memory because Imogen erased it, at Violet’s own request. The book does not say why, or how much was erased.
What is confirmed
- Violet passes out after killing Theophanie and wakes twelve hours later.
- Imogen’s signet lets her erase memories, and she tells Violet she did what Violet asked.
- Xaden told Sgaeyl he had a plan and needed Violet to agree to it.
That last point is the best textual hint that the twelve hours involved Violet meeting Xaden and agreeing to something.
What is theory
The most common explanation is protection. If Violet cannot remember Xaden’s plan or whereabouts, nobody can pull it from her through torture, a memory reader like Dain, or another inntinnsic. Secrecy and safety of the people she loves are also popular readings. All of these are interpretations. The book confirms a memory erasure on Violet’s request. It does not confirm that the erasure covered every detail, that she knew in advance exactly what she would be forgetting, or what the motive was.
Yarros has said readers will learn what happened in the missing hours by the end of Book 4, and she has been coy about whether Imogen has erased Violet’s memories at other times in the series.
Who dies in Onyx Storm? Deaths and survivors
The ending has fewer headline deaths than the previous two books, but several outcomes are easy to get wrong. This table separates deaths from characters who are merely missing or injured.
| Character | Outcome | Explanation |
|---|---|---|
| Quinn Hollis | Dies | Stabbed by a venin in the turret fight; dies in Imogen’s arms. |
| Theophanie | Dies | Violet kills her with the marble dagger from Aaric. |
| Trager (and his gryphon) | Dies earlier in the book | Killed during the Zehyllna sequence. Not part of the final battle. |
| Unnamed riders and elders | Die | Four riders, their dragons, and three elder riders are reported killed in the battle. |
| Panchek’s dragon | Dies | Drained by Berwyn after Panchek argues with him. |
| Panchek | Unclear | His betrayal is exposed, but the ending does not make his fate clear. |
| Xaden Riorson | Alive, missing | Transformed further toward venin; not dead and not cured. |
| Garrick Tavis | Missing | Named among the missing riders. Missing is not the same as dead. |
| Mira Sorrengail | Survives | Her throat is cut, but Brennan and Sloane’s siphoned power save her. |
| Brennan Sorrengail | Survives | Present at Riorson House at the end. |
| Imogen Cardulo | Survives | Loses Quinn, reveals a second signet, and erased Violet’s memory. |
| Tairn | Alive | Reported to be in a deep, foggy state needing rest. |
| Sgaeyl | Alive | Wounded but survives and leaves with Xaden. |
| Andarna | Alive | Returns during the fight and later speaks to Violet in Tairn’s place. |
| Berwyn | Alive | Knocked unconscious by Xaden’s channeling. |
| Bodhi Durran | Unaccounted for | Not clearly placed at the end. |
Does Mira die in Onyx Storm? No. She comes close, but she survives.
Who is Xaden’s new venin brother?
The book does not name him. In Xaden’s final chapter, he realizes Berwyn has created another venin “sibling” for him. In this context, a venin brother means someone else who was turned by the same Sage. Xaden’s reaction is horror, because the person chose this after watching what Xaden has endured. The text uses male pronouns, which narrows the field but does not identify anyone. Get complete guide on Onyx Storm Characters, Dragons & Signets.
What the ending confirms is that someone Xaden knows turned venin. Everything else is theory, as the table below shows.
| Candidate | Evidence readers point to | What remains unconfirmed |
|---|---|---|
| Bodhi Durran | Close to Xaden, strong family resemblance, absent when Violet wakes. Some reviews note he is seen retching in Imogen’s chapter. | No confirmation he turned. His absence has other possible explanations. |
| Garrick Tavis | Xaden’s best friend, named among the missing riders, and watched Xaden struggle. | Being missing is not proof of turning. He also appears helping Imogen earlier. |
| Brennan Sorrengail | Readers noted that a scar from his resurrection was absent after Sloane’s siphon. | He is present with Violet at the end, which weighs against him. Nothing confirms a link. |
| Aaric | Revealed as a precog with unusual knowledge of the fight. | No textual sign he turned. |
Any claim that Bodhi or Garrick “turned venin” is speculation. The book does not state it.
Who is the traitor in Onyx Storm?
The traitor is Commandant Panchek. In Xaden’s chapter, Panchek and his dragon are caught in the same net, and Xaden realizes Panchek has been passing information to the venin army the whole time. Panchek then argues with Berwyn, who kills Panchek’s dragon.
This matters for Navarre because the leaks came from inside Basgiath’s leadership, so the army’s plans and defenses may have been exposed for some time. The ending does not say how long the betrayal ran or what happens to Panchek next.
What happened to the missing dragon eggs?
Six eggs are reported missing from the hatching grounds, along with four riders including Garrick. Xaden is presumed responsible, but the book does not say how the eggs were taken, where they went, or why.
Possible implications are theory only. One idea is that the eggs are part of an alliance deal, since the Isle kingdoms, including Unnbriel, have shown strong interest in dragons earlier in the book. Another is that the eggs were taken to protect them from the venin, or that they are tied to Xaden’s plan. None of these is confirmed.
What does the Onyx Storm ending mean for Book 4?
Confirmed setup
- Xaden is missing and further along the path toward venin, with Violet’s bond to him silent.
- Violet is married to him but remembers nothing about it.
- Imogen holds the answer to what Violet asked for, and her grief over Quinn is fresh.
- Violet has a dangerous second signet she has barely explored.
- Panchek’s betrayal is exposed.
- Six eggs and four riders are missing.
- Someone close to Xaden has become venin.
- Berwyn survives.
Possible theories
- The memory wipe protects a secret plan Xaden and Violet agreed to.
- Dream-walking becomes Violet’s way to reach Xaden.
- The marriage secures Tyrrendor, or is part of a larger scheme.
- The eggs were taken to protect them or to trade.
- Bodhi, Garrick, or another character is the new brother.
Because so much happened outside Violet’s view, a wider range of points of view in Book 4 is a reasonable expectation, but that is a prediction rather than a fact.
