There was no deficit of perform at the end of "Onyx Storm."

Hints from 'Threshing Day'

On September 29, 2026, Yarros released a new "Empyrean" gathering called "Threshing Day." It tells the stories of 13 cadets at Basgiath as they association alongside their dragons in the high-stakes, frequently life-threatening cognition known as Threshing. Violet made former as the archetypal passenger to association two dragons on her Threshing Day in "Fourth Wing."

Most of the "Empyrean" sequence is told from Violet's item of view, but Yarros stated during an appearance on the "Fantasy Fangirls" podcast in October 2025 that she plans for the fourth installment to be told from multiple perspectives, including the character Sloane Mairi specifically. "Threshing Day" offers a extend to those new perspectives, as all the featured riders are characters who could inform forthcoming "Fourth Wing" stories, akin Sloane, Xaden, and Imogen.

The gathering additionally addressed a storyline equipment Yarros has used in the novels. After riders association a dragon, the passenger announces the dragon's name to the Scribes so it can be recorded, fairly than the dragons communicating immediately alongside the Scribes. Yarros earlier stated that creates the possible that the dragons or riders are lying concerning their identities.

It is forbidden for riders to association alongside their straightforward ancestors' dragons, as it allows riders to create second signets. In the text, it appeared akin several dragons wanted to association alongside the children or grandchildren of rebels they had worked alongside in the past, skirting the rules. However, it wasn't apparent how that worked until "Threshing Day."

In several cases, akin that of Imogen's dragon Glane, the dragon pretends to be person he or she is not, taking advantage of the fact that it is difficult for humans to inform dragons apart. For others, it is individual lies that authorize them to interrupt the rules. Xaden's dragon, Sgaeyl, was capable to association alongside him since his grandma lied concerning who his gramps was.

Yarros additionally included scenes showing dragons specifically seeking out the insurgent children, confirming that the dragons are invested in the combat against venin as well. Both Sloane and Xaden's cousin, Bodhi Durran, are told by their older peers during their Threshings that a dragon is looking for them, intending to association alongside them in part since of their ties to the rebels.

"Threshing Day" offered additional understanding into who may have turned venin at the end of "Onyx Storm" as well.

Speaking at an event in Denver on February 2, 2025, Yarros advised readers to "pay notice to who's missing at the end" and "someone who feels akin any they have stated is not enough, which is continually the case whenever you rotate venin."

Bodhi, Garrick, and Violet's brother Brennan fit that clarification at the end of "Onyx Storm," and all three appear in "Threshing Day."

Yarros shared several clues for publish four during promoting 'Onyx Storm'

Yarros went on an "Onyx Storm" publish tour following the book's January 2025 release, offering several understanding into the series' forthcoming as she connected alongside fans.

At an event in Los Angeles on January 21, 2025, Yarros said, "Someone you affection won't create it in publish four." That comment isn't that surprising, as cherished characters have died in all installment of the series. However, Yarros got additional particular alongside her hints as her publish tour continued.

At an event in St. Louis on January 31, 2025, Yarros shared that readers have additional to detect concerning the isles Violet explores in "Onyx Storm." When presenter Lexi Ryan asked her why there was no map of the isles included in "Onyx Storm," Yarros stated it "was deemed to be too spoilery" by her editorial team, suggesting Violet doesn't cognize all she volition concerning the isles by the end of publish three.

Speaking additional on signet powers in Denver, Yarros stated readers had lone seen "like 10%" of Violet's dream-walking abilities, in part since others who developed the power would have been killed, making it difficult for Violet to study how to use the signet.

"There's likely one individual living that can train her," Yarros said, although she gave no data concerning who that individual is.

She additionally stated Xaden's "inntinnsic" signet has lone reached "like 50%" of its potential, so his mind-reading abilities volition apt develop in publish four.

And Yarros revealed at the Los Angeles Festival of Books in April 2025 that she has a heading picked out for the fourth book, although she didn't say what it was.

Yarros offered additional data concerning the next 'Empyrean' novel in delayed 2025

When Yarros appeared at Romantasy Bookcon in Orlando in October 2025, hosted by Fabled Fantasy Events, she said alongside the hosts of the "Fantasy Fangirls" podcast, Lexi Ayala and Nicole Holleman, concerning the "Empyrean" series.

Yarros additionally warned that readers "should really be prepared in publish four to see Xaden act his villain era," indicating his marriage to Violet won't halt him from going complete venin in the next "Empyrean" novel.

The "Fantasy Fangirls" additionally asked Yarros if Imogen had been wiping Violet's memories at another times in the "Empyrean" series, which many readers had been wondering following the ending of "Onyx Storm." Rather than giving a straightforward answer, Yarros said, "I think it depends on what you accept of Imogen's character. What has Imogen shown you of her character? What has she told Violet concerning her signet?"

In the "Empyrean" series, readers lone see Imogen rub memories whenever Violet or Xaden specifically ask her to. However, since the sequence is mostly told from Violet's constricted perspective, there may have been occasions whenever Imogen wiped people's memories without Violet's knowledge. The inclusion of multiple POVs in publish four could recommendation new insight.

Likewise, Yarros addressed several of her readers' concerns surrounding Bodhi, as there is a contingent of "Empyrean" fans who think Xaden's related has feelings for Violet, saying, "Bodhi has a item for what Xaden has. But he doesn't desire to."

Her reply indicates that Bodhi may be envious of Xaden fairly than in affection alongside Violet. And considering he is among the possible candidates to have turned venin at the end of "Onyx Storm," Yarros' reply is particularly eyebrow-raising.

Finally, Yarros told readers to pay notice to the dreary dragons in the "Empyrean" series, encouraging them to ask themselves why there are so few dreary dragons in the world, adding that it's "very relevant" that two new baby dreary dragons hatched in "Iron Flame."

Hopefully, Yarros' clues can tide readers complete until publish four is published. In the meantime, they can read another romantasy novels to create the delay a bit additional bearable.
