Xaden's "villain era" and the mystery of the missing 12 hours

The fourth novel in The Empyrean series will center on the fallout of the events in Onyx Storm, specifically addressing the twelve hours of memory wiped from the protagonist, Violet Sorrengail, by the character Imogen. According to the report, this penultimate book will explain Xaden Riorson's current whereabouts and the dispapearance of other riders and dragon eggs.

A significant portion of the narrative will explore the psychological damage of Xaden Riorson's soul after his transformation into a venin.. yarros has explicitly stated that the story will be an "emotional heartbreaker" as Xaden enters what she describes as his "full villain era." This shift suggests a darker trajectory for the series' primary romantic lead, moving beyond the internal struggle seen in previous volumes.

A beloved death and the dragon lying about its name

In a move that will likely polarize the fanbase, Rebecca Yarros confirmed that a beloved character will not survive the fourth book. While the author has not named the victim, she did offer a specific reassurance that the character Broccoli will remain unharmed. This indicates that the stakes for the remaining cast have escalated as the series nears its conclusion.

Beyond the human casualties, the report says that Yarros has confirmed at least one dragon is lying about its identity. This revelation adds a layer of espionage to the creature-bond dynamics, sparking widespread speculation among readers about which dragon is operating under a false name and what their true allegiance might be.

A late 2027 release for the penultimate of five novels

The timing of the next release reflects the massive scale of the The Empyrean world. Yarros has hinted that fans may have to wait until late 2027 or potentially longer for the fourth book to hit shelves. This timeline follows the massive viral success of Fourth Wing, published in 2023, which helped define the modern "romantasy" genre by blending high-stakes military fantasy with intense romance.

The series was originally conceived as a five-novel arc. Because the fourth book is the penultimate entry, it serves as the critical bridge to the final conclusion. Yarros is currently mapping out the final two novels to ensure the series ends with a strong, cohesive resolution, which explains the extended production timeline for this increasingly large volume.

Whether Berwyn is a Sage and the search for an "Earth" title

Several critical plot points remain unverified,leaving the community to rely on theories. One primary question is the true identity of Berwyn; some readers propose he is either Xaden's father or the mysterious venin known as Sage, who has been a looming threat since the first novel. Additionally, the nature of the bond between the dragons Tairn and Sgaeyl remains an open questiion, with some theorizing that Tairn broke the bond to protect Violet Sorrengail from the trauma of Xaden's venin state.

The title of the fourth book also remains a mystery, though fans are analyzing a pattern of elements. Following Fourth Wing (air), Iron Flame (fire), and Onyx Storm (water), speculation suggests a theme of earth or ice. Potential titles like Silver Throne or Silver Reign have emerged as favorites among the community, though Yarros has not yet confirmed any specific name.
