Onyx Storm: Seriously, What Just Happened?! Dissecting That Wild Cliffhanger

Rebecca Yarros's The Empyrean Series really grabbed readers worldwide, building a massive fandom around its thrilling mix of dragons, war, and, let's be honest, a lot of romance. After the huge hits Fourth Wing and Iron Flame, the third book, Onyx Storm, landed on January 21, 2025. It immediately shot to the top of bestseller lists, even becoming the fastest-selling adult novel in two decades. But, true to form for this series, Onyx Storm didn't just deliver on action and emotional stakes; it ended with a "jaw-dropping cliffhanger" that's left us all scrambling for answers and churning out fan theories across the internet. We're going to dive into that electrifying ending, pick apart its core mysteries, check out some popular fan speculations, and get ready for the next book, because, wow, we need it.

Remember Iron Flame? Let's Not Forget That Pain.

To really get why Onyx Storm's ending hit us so hard, we've got to quickly look back at Iron Flame's brutal conclusion. That second book left us reeling from two major sacrifices: General Sorrengail's self-immolation, all to fix Basgiath's wards, and then, even more crushing for Violet, Xaden Riorson's agonizing choice to use forbidden earth-magic. He basically turned partially venin just to save Violet's life. That act stained his eyes scarlet, fundamentally changing who he was and throwing his relationship with Violet into unprecedented darkness. Iron Flame's ending cemented the venin as an existential threat and left us with the ultimate question: could Xaden be saved, or was he now lost to the very evil they were fighting? That powerful cliffhanger really set the stage, emotionally and thematically, for everything that blew up in Onyx Storm.

After the Storm: What's With All the Secrets?

Onyx Storm wraps up with an epic, devastating battle between riders and venin. Everyone gets pushed to their absolute limits and then some. In the wild aftermath, Violet Sorrengail wakes up confused at Riorson House, which is Xaden's home, with a huge twelve-hour chunk missing from her memory. What she finds immediately is nothing short of shocking: she's wearing a wedding ring, complete with a blessing from Dunne's head priestess, confirming she married Xaden. Adding to the confusion, her brother Brennan tells her Xaden, along with three other riders including his best friend Garrick Tavis, are gone. A super cryptic note from Xaden just says, "Don't look for me. It's yours now." The final gut punch comes when Imogen Cardulo, a fellow rider, admits she erased Violet's memory of the night's events, saying "What you asked me to." That left Violet — and all of us — feeling profoundly disoriented and, honestly, a little betrayed.

Xaden's Dark Path and That New Venin "Brother"

One of the biggest parts of Onyx Storm's ending is Xaden Riorson's deeper dive into venin power. To finally end that huge battle, Xaden goes all in, channeling from the earth to wipe out dark wielders and their wyvern. This just strengthens his connection to that forbidden magic. And from his perspective, he makes a chilling discovery: he's got a new "venin brother," an unnamed rider who's also turned. This revelation sent shockwaves through the fandom, immediately sparking intense debate over who this new corrupted ally could possibly be.

Fans have cooked up several big theories about Xaden's "new brother":

• Bodhi: Lots of us strongly suspect Bodhi, Xaden's cousin and close friend. He's a strong candidate. This theory gets support from things we noticed about Bodhi in the book, like him getting seriously hurt during the battle and then being totally absent from the final chapter. Rebecca Yarros herself dropped a hint in an interview, saying the new venin is "the one who felt like he didn't get what he wanted." Some of us think that points right to Bodhi's struggles with leadership and responsibility. If Bodhi turned, it would also make sense why Xaden would rush to marry Violet, since Bodhi wouldn't be fit to rule Tyrrendor anymore.
• Garrick: Another strong possibility is Garrick, Xaden's super loyal best friend, who's also one of the missing riders. Some theories suggest Garrick might have channeled way too much using his distance-wielding signet to help with evacuations, possibly leading to his corruption. His transformation would feel like a really deep personal betrayal for Xaden, who truly sees him as a brother.
• Naolin/Berwyn: This one's a bit more out there, but still intriguing. It connects the new venin to Naolin, Brennan's old dragon rider, who we thought died trying to fix a ward. Some believe Naolin might have turned venin while trying to save Brennan and Tairn's bond. Or even that the venin Berwyn, who shows a personal interest in Xaden and really hates dragons, is actually Naolin. That would add a layer of tragic irony and give Brennan, and maybe Tairn, a deeply personal enemy.

The identity of this new venin brother is a huge unsolved puzzle, promising some serious emotional and strategic consequences for the fourth book. Can't wait.

Violet's Choices and Imogen's Big Secret

One of the most confusing and talked-about parts of Onyx Storm's ending is Imogen's bombshell: she erased Violet's memory because Violet asked her to. This self-imposed amnesia brings up so many questions about Violet's reasons and what secrets she thought were too dangerous to remember.

Fan theories are flying about why Violet would ask for her memories to be wiped:

• Protecting Vital Information: The most common theory is that Violet wanted her memory wiped to keep crucial info from falling into enemy hands. In a war where betrayal and mind-reading venin are constant threats, just erasing her own knowledge could be a drastic but necessary move to protect allies, strategies, or even Xaden himself. This totally fits with Violet's character as a quick-thinking strategist, someone willing to make huge sacrifices for the greater good.
• Strategic Alliance or Personal Safety: Some readers wonder if Violet might have seen something so devastating or learned a truth so dangerous that forgetting was the only way she could function or even stay sane. It's also possible the memory wipe is part of a bigger, pre-arranged strategic plan that Violet agreed to in a moment of desperation, maybe to protect Xaden from his venin nature or to hide where he went.
• Imogen's Deeper Role: While Imogen says she did what Violet asked, some fans are questioning if Imogen's signet, which lets her manipulate memory and move undetectably, might have been used on Violet at other times in the series without her even knowing. There's speculation that Imogen could be playing a more complex role, perhaps even having erased Xaden's memories of Violet to protect her from his venin side, which would then explain his cryptic goodbye note. Imogen's signet is definitely a powerful and potentially dangerous tool that will be huge in future revelations.

Honestly, those missing twelve hours hold the key to so many of Onyx Storm's mysteries. Getting them back is going to be a pivotal plot point in the next installment.

The Ring, the Marriage, and Xaden's Goodbye

That sudden, totally unexplained marriage between Violet and Xaden, plus his ominous "Don't look for me. It's yours now" note, is another huge part of Onyx Storm's cliffhanger. This development completely reshapes their already complicated relationship and throws a ton of new questions our way.

Theories about the marriage and Xaden's message are varied and, predictably, passionate:

• A Political or Strategic Union: Many of us think the marriage isn't really about traditional romance in that moment, but more about a strategic alliance. Given the ongoing war and the need for new leadership in Tyrrendor (especially if Bodhi has turned venin), marrying Violet would officially make her the Duchess of Tyrrendor, securing the region under a trusted leader. This would let Xaden fulfill his duty to his family and people, even if it meant exiling himself.
• Protection for Violet: Xaden's note could be a desperate attempt to put distance between himself and Violet for her safety. He's probably terrified of the unpredictable, corrupting influence of his venin power. He might believe his continued presence would endanger her or speed up his full transformation.
• The Fate of Xaden's Soul: The "It's yours now" phrase has led to intense speculation about what happened to Xaden's soul. Some theories suggest he might have transferred what was left of his soul into Violet's wedding ring, which, notably, is made with an emerald matching his sword, the Blade of Aretia. Others point to an empty glass box Xaden kept in their room, believing it might be a container for his soul, which aligns with the idea of keeping his soul separate from his increasingly venin body. This dark magic theory hints at a desperate attempt to preserve his essence, even if it means losing his physical presence.
• The Dragon Bond: The tricky state of Xaden's venin transformation also makes us wonder about the bond between Tairn and Sgaeyl (who are mates), and consequently, between Violet and Xaden. Some fans speculate that Tairn and Sgaeyl might have broken their bond to let Xaden escape and hide. That would, in turn, sever the bond between Violet and Xaden, allowing them to exist independently without one dying if the other falls. That would be a monumental shift in the series' magic system and character dynamics, honestly.

The true meaning behind Xaden's actions and the significance of their marriage will undoubtedly be central to Violet's quest in the upcoming book. We'll see.

Godly Connections and Powers Beyond Belief

Onyx Storm really deepens the mystical elements of The Empyrean Series, especially when it comes to Violet's connection to the gods. Throughout the book, Violet keeps showing multiple ties to the goddess Dunne, the goddess of war. Her unexpected marriage blessing from Dunne's head priestess highlights this connection, and many of us predict Dunne will play an even bigger role in the fourth book. Some even theorize that Violet's incredible lightning abilities are a direct gift from Dunne, and her full dedication to the goddess could just supercharge her power.

What's more, the ongoing mystery of Violet's second signet finally got a bit clearer, though we still don't know the full implications. While some initially thought she had a "truth-seeking" power, Onyx Storm assures us it's "far more dangerous" than her lightning wielding. That definitely hints at some powerful, maybe even unsettling, abilities that we'll explore in future novels. There's also talk about other gods, like Malek, the god of death, potentially getting involved, especially if Violet has to retrieve Xaden's "dead" soul. The whole mix of divine intervention, ancient magic, and Violet's evolving powers promises to add so many layers to the fight against the venin.

The Unwritten Future: What's Next?

Onyx Storm's ending has totally set the stage for an explosive continuation of The Empyrean Series. Rebecca Yarros has confirmed the series is planned for five books. While Onyx Storm came out in January 2025, Yarros said she wouldn't write the fourth book at the same breakneck pace as the first two; she's taking time for a contemporary novel and some family breaks. However, as of March 2026, Yarros officially announced she's working on book four, though no firm release date is set yet. We're waiting on pins and needles.

Fans are eagerly anticipating how all these unresolved plot points will shake out:

• The Hunt for Xaden: Violet's main goal will absolutely be to find Xaden, figure out what he did, and see if there's any way to cure his venin affliction. Her journey to save him, especially given his note telling her not to look for him, will drive so much of the narrative.
• The Venin Problem: With Xaden's new "brother" and the corruption deepening, the war against the venin is more dangerous than ever. The fourth book will likely explore new tactics, alliances, and the true extent of the venin's power and origins. It's not looking good.
• Unpacking Those Missing Hours: The truth behind Violet's lost memories and her request to Imogen will be a crucial reveal, potentially changing how she understands her relationships and the war itself.
• Violet's Growth: With a new grasp on her divine connections and the full scope of her second signet, Violet's development as a leader and a wielder of immense power will be central. She's also expected to search for allies beyond Navarre, and possibly even the lost seventh tribe of dragons that Andarna is so curious about.
• Character Fates: Rebecca Yarros ominously hinted that "Someone you love won't make it in book four." That comment sent shivers through the fandom and really cranked up the anticipation for the next installment. Who could it be?!

That Onyx Storm cliffhanger? It's a truly masterful stroke of narrative tension, leaving The Empyrean Series in a state of thrilling uncertainty. From Xaden's shocking venin transformation and mysterious disappearance to Violet's memory loss and unexpected marriage, the third book completely redefined the stakes and possibilities for the world of Navarre. The intricate web of fan theories swirling around those missing twelve hours, the identity of the new venin "brother," and the ultimate fate of Xaden's soul just shows how much this story has impacted its readers. As Rebecca Yarros carefully crafts the fourth book, the promise of revelations, deeper magic, and unforeseen sacrifices ensures that the storm unleashed in Onyx Storm will keep raging, drawing fans ever deeper into this irresistible world of dragons and riders. Honestly, I can't wait to see what happens next.
