Unmasking Xaden’s New Venin Brother: A Theory-Driven Analysis Post-Onyx Storm

Spoiler Warning: This post contains full spoilers for the Empyrean series through the end of Onyx Storm.

The conclusion of Onyx Storm left readers with numerous lingering questions, the most tantalizing of which is the identity of Xaden’s new Venin brother. Following the successful application of a predictive methodology to identify the Outlands’ champion in Iron Flame, this same approach is now employed to analyze who Rebecca Yarros’s mysterious new Venin rider might be.

Clues from the End of Onyx Storm

The Xaden perspective chapter provides the most revealing insight. Xaden discovers he has a new Venin brother and finds an unconscious dragon in the valley. His shock indicates he knew the individual before their transformation and did not anticipate this turn of events:

“My new brother—and the unconscious dragon lying in the valley behind the canyon. How could he do this, choose this, after watching me stumble and fall over the last five months?”

This strongly suggests the new Venin brother is a dragon rider, was familiar with Xaden’s struggle, and turned Venin only very recently—likely during the Battle of Dralor itself. Xaden notes that he can sense other Venin since January, which supports the idea that the transformation had to have occurred at a moment when he wouldn’t have sensed it beforehand.

Xaden’s thoughts also reveal his conflicted emotions: he fears his brother may be used against him by Berwyn but still refuses to kill him during the Onyx Storm, sparing him while eliminating other threats. He also appears to read the brother’s thoughts or intentions—possibly indicating a telepathic connection or deliberate mental vulnerability from the brother.

Disqualified: Panchek

Some confusion has arisen, particularly among audiobook listeners, about whether Panchek could be the new brother. However, multiple textual clues disqualify him:

  • He is clearly not the unconscious rider in the valley.
  • He is present and vocal during the Onyx Storm scene.
  • Xaden attempts to kill Panchek, a stark contrast to sparing his actual new brother.
  • Panchek’s dragon is described in a separate location.

Candidate 1: Aaric

Aaric is a puzzling but not implausible candidate. His signet of precognition, hinted at as early as January, could have allowed him to foresee the necessity of turning Venin. However, there are complications:

  • There’s little evidence he was aware of Xaden’s struggle as early as December.
  • Xaden and Aaric’s relationship evolves from hostility to mutual respect, especially in battle.
  • Aaric subtly works in tandem with Xaden in scenes Violet doesn’t fully interpret.

Despite these intriguing threads, the five-month timeline is a stretch, and Aaric’s distance from Xaden during key emotional moments makes his candidacy unlikely.

Candidate 2: Bodhi

Bodhi is a stronger contender. He knew of Xaden’s Venin status from December, fulfilling the timeline criteria. Though initially portrayed as reasonable and resistant to reckless decisions, Bodhi’s behavior becomes increasingly erratic throughout Onyx Storm.

Notable moments:

  • He issues a strong ultimatum to Xaden: either lead as a Duke or face losing the throne to someone else.
  • He fights to support Violet and Tyrendor but becomes desperate when he realizes his power is insufficient.
  • After his dragon, Cuir, goes unmentioned during the chaos at Dralor, he is seen grounded and potentially transformed.

However, there are logistical inconsistencies:

  • His location during Xaden’s final confrontation is unclear.
  • There’s no mention of his presence in the canyon, nor is Cuir the unconscious dragon.

Thus, while emotionally and narratively compelling, Bodhi’s candidacy lacks key physical evidence.

The Most Likely Candidate

Garrick is the most consistent match across all available data:

  • He learned about Xaden turning Venin back in December.
  • He is Xaden’s closest companion through the events of January to May.
  • He exhibits increasingly protective behavior, especially after Mira’s death.
  • His dragon, Chradh, is missing during the final chapters, possibly indicating unconsciousness or separation during Garrick’s transformation.
  • Garrick is present throughout the battle, saves Imogen, and delivers a cryptic line about needing to “find some exploitative way to do something,” which could signal intent to turn Venin.

Further supporting evidence includes word from Rebecca Yarros that the identity of the brother can be found among the “missing riders.” Garrick, explicitly listed as missing, fits this description.

Conclusion

While Aaric and Bodhi both offer compelling narrative and thematic justification, Garrick is the only character who aligns with every major clue:

  • The five-month awareness of Xaden’s transformation.
  • A close bond with Xaden.
  • Recent absence from the battlefield.
  • A missing dragon.
  • A plausible emotional and strategic reason to become Venin.

The revelation that Xaden has only one new Venin brother in the canyon narrows the final choice. All signs point to Garrick.

Still, with so much room for interpretation, debate is welcome. Share your theories and discuss alternative interpretations here in the comments or under the video.

Share that Venin and Wyvern are real!

  1. Just came here to say Zaboomafoo!! I used to watch that ALL the time growing up lol. I really love hearing in detail your thought process- super helpful and you have me 100% convinced! Would also make sense why Imogen stays behind because she lost Garrick in addition to having to wipe Violet’s mind and support her moving forward.

  2. I think that Garrick is the most logical person, mainly because he was distancing walking all over the continent so that he could have drawn power from the ground, either accidentally or purposely.

  3. I think that Garrick is the most logical person, mainly because he was distance walking all over the continent so that he could have drawn power from the ground, either accidentally or purposely.

  4. I agree partially, and I think that nearly all of us are convinced that Garrick is Xaden’s new Venin brother, because all signs and clues that Rebecca Yarros has given us point to him.
    On the other hand, I also don’t think that it’s Garrick, precisely because it would be too obvious. I think that Rebecca Yarros wants to make us think, and Garrick is ‘the obvious choice’. He’s always supporting Xaden and has known about his ‘venin problem’ for five months, and also is missing at the end of Onyx storm.
    But what if it wasn’t someone who has known about Xaden being Venin or hasn’t been verbally told, and has rather been speculating that Xaden was Venin?
    Xaden says: “After seeing me stumble and fall”. What if they saw him slipping away into the ice, but never actually knew that he had turned into Venin?
    Gosh, sorry if that was long, I sort of feel like Violet trying to convince Ridoc that the code to opening her father’s book isn’t Lilith but Aimsir. Anyway, this is still a very good theory, and I’m convinced that it’s probably going to be Garrick. Probably.

  5. I think it’s Bodhi. Bodhi being Xaeden’s heir is mentioned several times in this book. Him turning venin explains Xaeden and Violet’s marriage at the end of the book. She now has a legal claim to Trryendor, and can keep the king from installing someone from Navarre to that throne.

    Given that Garrick is a far walker, I wonder if simply got stranded somewhere after depleting his signet. He may come back suddenly as soon as his magic replenishes.

    1. it’s also possible that the reason they married is to protect Violet. She is the easiest way to kill Xaden, who is a big threat to the country as a venin. By Violet having legal claim to Tyrrendor she has way more political power that can protect her for when people want to kill her to kill Xaden.

      1. I agree the marriage was to protect Violet and Tyrendor from venin, including Xaden. Xaden would have read the book on venin too and realized venin don’t attack their prior families or homes. Well now all of Tyrendor is Violets home. Xaden also references protecting the people Violet loves, he does not just mean her squad. Violets squad mates are protecting the civilians at the end of onyx storm. Violet loves the people which is why her becoming a leader of Tyrendor is Xadens choice. Bodhi doesn’t care about the “people” he cares about Xaden. Violet will ensure the people are taken care of.

  6. This is something that I’ve never seen suggested: Onyx Storm chapter 60:
    Having two lightening wielders on any side wouldn’t tip the balance; it would destroy it. The same as shadows.

    What if Xaden and his new brother don’t join the venin but wage war on them instead. Two shadow wielders- Xaden and Lynx…

    1. That’s an interesting observation, since we don’t know where the Iron squad’s first years are. I suppose that they were in that party Violet heard when she ‘woke up’ outside Riorson House. So, if I understood correctly, you’re saying that Lynx is the one who turned.
      I can’t really see this. The way Xaden talks about his new brother makes it sounds like it’s someone he knows and possibly, most probably cares about. I don’t actually think that there is a single written conversation in between Lynx and Xaden.
      Also, about them waging a war against them…
      I can definitely see Xaden doing it, but… we don’t actually know much about Lynx except that he’s from Luceras (I think) and he’s the supposed ‘response’ to Xaden.
      Unless…
      What if someone else had shadows? A Marked?
      I know that everyone wants him to be an intinnsic, me as well, but… maybe Bodhi?
      Mmh… interesting theory.

      1. Now I’m actually realizing that Violet was probably saying that if they could have both Lynx and Xaden on their side would destroy the balance.

  7. i have a reason that would put some heat on Bodhi. Mentionned a couple of times during the books, Bodhi is second in line to Xaden for the Duke of Tyrrendor right ? thats why in the last battle Xaden explicitly told him to stay behind in case something happens to him. Bodhi did not want that. In the end of Onyx Storm, Violet wake up with memory lost, ring on her finger, act of mariage in hand with a note to take care of tyrrendor.. Why ?! Bodhi was supposed to take the throne, why would Xaden, recently turn Venin, would go get Violet to get married just so she could be Duchess of Tyrrendor ? Violet would have been shocked to see Xaden fully Venin, a good reason to erase the memory but if Bodhi was there to take the throne… why would the quickie mariage would need to take place to secure the throne ?? Xaden had full 100% confiance in Bodhi to be Duke and would not put all this responsabilities on Violet if not ABSOLUT’Y neccessary.. well I hope someone reads this, if you did thank you for reading my 2 a.m. theory

  8. Rebecca Yarros just posted a blurb on her Instagram. If you have not seen it, it reads, “‘I’m with you to the end, Brother. But someone has to say it,’ Garricks face tightens. ‘This plan risks everything our parents worked for,’ he warns, already reaching for his flight jacket. ‘Everything they died for.’
    ‘They died for us, for a world where we have the knowledge to make our own choices.’ The shadows at my feet sharpen as I sheath the second sword across my back. ‘Violet’s my choice. I’m more than willing to die for her.’
    ‘Let’s go hunt some wyvern.’”

    From this, we see that Xaden still loves Violet, he still has part of his soul. But it also mentions the word Brother…in a conversation between Xaden and Garrick. Does this mean Garrick is the new brother? They also mention hunting wyvern, does this mean they both have enough of their souls to know that the weight of the world is on their shoulders. But…this could also mean that they got their souls back and are now healed meaning someone found a cure.

    1. Heeeellooo! I was sooo excited to see this! I think the bonus chapter is for Chapter 35 from Iron Flame. For when Garrick and Xaden went to hunt for wyvern to drop them off at the borders to expose Navarre’s secret

  9. I think it’s Brennan, and you can see why when you examine his dragon’s name… a lot of the dragons have Gaelic names, and each of those ring true to something about them. For example, Aotrom means light/silly/humorous, Tairneanach means thunder, and Sgaeyl means shadow. Now, listen to this… Brennan’s dragon is Marbh. Marbh means “dead person”.

    Now, I don’t know if RY chose this name because Brennan was originally dead, or if she chose it because he would become venin. I know venin are seen as soulless, and the whole debate of the book is “are you still alive if you don’t have a soul?” So, maybe this was some foreshadowing.

    1. Hi! Just her to say – I’m on the Brennan wagon. We don’t know for sure that the new Vernon Brother departed with Xaden to wherever Vernon go. And Xaden may have been more reluctant to kill Vernon Brennan because he would believe Violet would have enough of him at that point.

      When Violet names her “line to cross” with Ridoc after finding the Iris’s (which Xaden overheard) she never names any of the Marked ones as being an end all be all. But I believe she mentions her family and friends. That last sliver of humanity Xaden is hanging onto after turning would have prevented him from doing anything to hurt Violet… like kill her brother.

      Xaden has accepted his fate (though he fought to prolong it) and doesn’t believe through all of Onyx Storm that he can be cured. Harris is HIS friend, not Violet’s. I think he may have killed Garrick as a “mercy”…

  10. I understand why people think it is Garrick. But I think RY gave us the clues to see it is Brennan.

    We are given three pieces of information in the Xaden POV chapter. The new ‘brother’ is:
    1. A rider, the dragon is explicitly mentioned
    2. Someone who has known Xaden is Venin and has been trying to help for five months – since Xaden turned or close to then.
    3. A man.

    Missing Rider

    RY also said to pay attention to who is missing in the final chapters. I am certain the intent of the multiple different POV chapters is to make clear where everyone is. To name check specifically where people are.

    Further, we know that when Xaden breaks and channels the Draithus wards are not yet up. His power “rushes over Imogen” in Draithus, up the pass, the cliffside and “fall(s) back at the magic that burns to the touch” – it is blocked by the wards of Aretia. But Trissa is in the process of weaving them, to get them up as the chapters closes. This seems to indicate the timing is simultaneous with the Xaden and Violet POV chapters.

    So we know:
    1. Imogen POV – she is with Dain, Garrick, Bodhi, Felix, Trissa (and Quinn)
    Note: Very explicit mention from Garrick that *he can not travel* again but will find another way to help, presumably looking for more daggers/imbued alloy to fire the ward stones.
    2. Rhi POV – she is with Ridoc, Sawyer (and Cat and Maren), she notes the first years should be at the top of the pass behind the wards but she will be yelling at Aaric and Sloane later because both disobeyed (Aaric went to the temple, Sloane delivered the package – presumably sent by Aaric because he knew she would be needed to save Mira)
    3. Ulices is in Lewellen (and Suri in Trevainne)

    So riders unaccounted for: Aaric, Sloane, Mira, Brennan, Kylynn, Kaori, Devlin, Emery, Heaton (and Blake but he’s a flier not a rider).

    Known for five months

    * People we can be confident have known for five months and watched him struggle: Violet, Imogen, Garrick, Bodhi, Brennan.
    * Ridoc and Mira knew but have not known for five months.
    * Aaric might have known through precog. Although it seems unlikely his powers had manifested way back at the time of the Battle of Basgiath. His powers seem to be manifesting only now given his confused face about the Temple of Dunne. But even if Aaric knew through precog, Xaden would not know that Aaric knew. The comment indicates Xaden knew that the other person knew about him.
    * Emery and Heaton do not know (Imogen closes the cell door so they don’t overhear Violet talking with Jack).
    * Unlikely Kaori and Devlin knew. Which leaves only Sloane and Kylynn, and both are women.

    Brennan is the only candidate that fits all three known requirements.

    1. I think so too! Also Brennan and Dain didn’t have any marks after Sloane tried to channel Dain’s powers to Brennan so he can heal Mira, that means he had to channel it from somewhere else. 🤷
      And he looks very fit after that and when Violet asks him how is it possible, he told her that Sloane had to give him more power than he needed 🤔.
      Also some people suggest that Naolin turned to venin so that is why Tairn don’t want to talk about him and that’s why is Sgaeyl so afraid for Xaden turning, because she saw what happened to Tairn. It is definitely Brennan.

  11. I would like to point out, Xaden told Violet, “I’ll use Tyrrendor to protect you, not you to protect Tyrrendor.” While its obvious that he used Tyrrendor to protect Violet, as title beats rank. But I think it also is a clue that Bodhi is not the new brother, he is however still helping Xaden with his plan.

  12. Firstly, I’d like to say sorry for misspelling names. I’ve been listening to the books, not reading them.

    Garrick is a great option, but for me it’s too obvious and not quite right. Also, him acknowledging that he is at his limit for distance weilding and how he states that he is still going to find some way to help, to me, says that he isn’t tempted to channel.

    I personally think its Dainne. He has the personality that would channel under the right circumstances, and it wouldn’t take that much persuading. Especially if he thinks that by turning he could “take out the head of the snake” so to speak. As readers our interactions with him in this book were more limited, but he was still present the entire time. He saw Xaden’s eyes at the same time as Riddoc. He has a type of intinsic ability that he could have grown, just like how Xaden’s grew enough to start reading Violet’s mind. So he could have watched as Xaden struggled with his own turning. He is at the battle, and Sloan states that she is shocked at how much power he actually possesses.

    Additionally, Xaden would be shocked that he chose to turn. And the way Xaden talked about the new “brother”, to me sounded more dismissive and less intimate. He wouldn’t talk that way if it was someone he loved like Garrick or Bohdi. Also, at the end there are still 4 riders missing: Pancheck is dead, Xaden is gone, Bohdi is gone, and I think Daine is the last rider.

    I’m just curious, do readers forget that Brennan is the one talking to Violet at the end of the book? He’s literally taking accounts of who is missing. I really don’t think that Brennan is venin. He was replenished from Daine after Mira’s healing. So as a tactician and healer, he’d have been behind the wards helping like he has been throughout the book.

    1. I’ve speculated Dain also simply because he refuses to “break the rules” and the only reason he wouldn’t kill Dain is because of Violet. Dain is violets long time friend, and while he isn’t a fan of Dain, anyone Violet LOVES gets protection from Xaden. Violet is not romantically in love with Dain however, I think Violet would cry over Dain like she did Liam. Which in part IF Dain DID turn for some odd reason, it would absolutely crush Violet. It’s crushing Violet that Xaden turned, now add in another person Violet cares deeply for and yeah, Violet would probably lose her shit and go on “violent” killing spree. Theirs only so much betrayal one can handle before getting violently angry at… well… everything. It would also be a plot twist and I agree Xaden would never want any connection to Dain in anyway, shape or form.

      1. Xaden saves Dain AFTER mentioning his new brother and sparring him and Berwyn from is onyx storm.

  13. The dragon of the rider was a green dragon as noted in the paragraph where berwyn says “I have another” this paragraph states that “berwyn stabs deep between the dragon’s scales and it dedicates, GREEN draining from its scales.
    Bodhi is the only male we know of with a green dragon. So that’s my guess but I could also see her surprising us by it being someone whose dragons color hasn’t yet been stated

  14. In fourth wing, Xadens point of view specifically lists Liam and Bodhi as the closest things to siblings to himself (Xaden). Chapter 27 in the bonus content. FF to OS before the last battle and Bodhis little man-trum with Xaden about wanting to drop out of BWC. Clearly Bodhi was having some identity issues and openly rejected becoming the Duke of Tyrrendor should anything happen to Xaden. Clearly the milk in their relationship is souring some in that specific scene. Which que the conversation topic change (way to change the subject RY) when Xaden opens the mail and reads the missive about that battle, and the missive from the temple of Dunne. Mean while Garrick is working his ass off to do “what was asked of him” in this specific battle. Bodhi? Openly rejecting Xaden before battle. How do the scales tip now?

    1. I also think possibly now upon re reading that the new brother is Kaori.

      Garrick and Bhodi are with Xaden to help Xaden whatever the cost.

      Kaori and pancheck randomly decide to go to Aretia this rotation with the cadets. Well we know pancheck was a traitor for the venins advantage. Kaori was probably with pancheck during this little meet up. Also Kaoris book is one of the items stolen in 4th wing, along with a squad who steals a uniform, and scribe and violet steals the map. I think this is foreshadowing from RY. We know the scribes are not to be trusted. I think personally Markham is venin, he lies just like Theophanie. Markham also wanted Violet, wanted to be her “teacher” just like Theophanie… where in venin ranks Markham is ? Well if he can be in the wards, underground… closer to the magic under Basgiath… has no dragon… is Markham the one leading the venin? Or is he just courting Violets “favor” just like Theophanie?

      Also Markham knew Jack Barlow was venin, yet used him to distract cadets after the propaganda in battle brief. What flipping professor would put a known venin among young, unsuspecting cadets ?

  15. Some clarifications and questions.
    1. I believe the text indicates that the green dragon Berwyn killed was Panchek’s.
    2. Wasn’t Trissa working to open the runes on a box they found in the Resson clock tower rubble? Was that addressed and I missed it?
    3. What was the gray hand print that scars Dain’s arm before Sloan siphons his energy to Brennan? And by the way, where is his father?
    4. Because we have primarily Violet’s perspective thus far, can we be certain that Liam has only appeared to her and not Xaden (or others), too. And weren’t he and Deigh buried, not burned? Could the new brother be Liam? I admit it’s a stretch since the characters consider him dead, not missing. But it was the author’s clue to ask about missing riders, not one of the characters.

  16. I think it’s Bodhi. In Iron Storm, Chapter 11, there was a recovered correspondence from Xaden to Violet where he spoke of Garrick, Bodhi and Liam. Xaden said that ‘Garrick is like my Dain, only trustworthy’ and continued on to discuss Liam and Bodhi. He explained they were the closest thing he had to brothers and the sentence about Bodhi read ‘..After Liam, Bodhi was and still is the closest thing I have to a brother, perpetually tagging along a step behind.’ The step behind just says it all to me, Bodhi doesn’t want to rule and gets quite irritated with Xaden about this throughout OS, probably because he wants to be with Xaden. I can’t see it being Garrick because the Venin already have a distance walker and magic likes everything in balance. I don’t think it’s Brennan because he’s not missing. Dain is an interesting theory that I’ve not considered but he’s such a stickler for a rule. Anyway, that’s my theory!

  17. The handprint on Dain is from Jack Barlow at the wardstone in Bagsaith. He drained a little of Dain before someone got him off of him.
