Prime Video’s Fourth Wing adaptation has its Xaden Riorson. Emilio Sakraya has been cast as the pivotal wing leader, joining Esther McGregor, who is set to play protagonist Violet Sorrengail. The pairing puts two central figures from Rebecca Yarros’ Empyrean fantasy series on the board as the project moves forward following its order to series in May.
Xaden is no small supporting part in this particular flight formation. The story places Violet at Basgiath War College, a punishing military institution where candidates train for the chance to become dragon riders. Violet, 20, had expected a quieter life, but her mother—a military general—orders her into the deadly candidate pool instead. Xaden is the wing leader she encounters in an environment governed by a brutally simple expectation: graduate or die.
That setup explains why this casting news is likely to matter intensely to established readers. A wing leader is a position of authority within the story’s military-school framework, and Xaden’s relationship to Violet sits at the center of a series that combines romantic stakes with dragons, warfare and survival training. “Romantasy,” the label frequently applied to the books, is shorthand for fantasy in which romance is a major structural element rather than a minor subplot. For a screen adaptation, getting the leads in place is therefore about more than finding actors for a dragon-filled fantasy world; it establishes the human dynamic expected to carry that world.
Sakraya joins the Empyrean adaptation
Sakraya’s credits span German and U.S. film and television projects. His past work includes Rhinegold, Tribes of Europa and Warrior Nun, while more recent projects include Those About to Die. He is also set to appear in the third season of One Piece.
McGregor, whose casting as Violet was already known, has appeared in We Were Liars. Together, the two actors take on characters whose circumstances begin with a sharp imbalance: Violet arrives at Basgiath under orders rather than by the settled path she had imagined, while Xaden holds an established leadership role in the college’s dangerous rider culture.
That distinction is useful context for viewers coming in cold. Basgiath is not described as a conventional school adventure where setbacks mean detention or a bad grade. It is a war college, its students are candidates for an elite dragon-rider force in the nation of Navarre, and the premise explicitly frames failure as potentially fatal. The adaptation’s challenge will be to make those pressures legible on screen while preserving room for the character-focused tension that attracted readers to the novels.
What is confirmed—and what is not
The show is a Prime Video production from Amazon MGM Studios and Michael B. Jordan’s Outlier Society. Meredith Averill is attached as showrunner and executive producer. A showrunner is the senior creative and managerial producer generally responsible for guiding a television series’ overall storytelling direction, coordinating writers and working across production departments.
Yarros is also an executive producer, an arrangement that gives the author a formal producing role on the adaptation. Jonathan Nolan and Athena Wickham of Kilter Films are executive producers alongside Jordan, Outlier Society president Elizabeth Raposo and Averill. Lisa Joy, co-creator of Westworld, is an executive producer and will direct the first episode.
Related coverage includes Emilio Sakraya Cast as Xaden Riorson in Prime Video’s Fourth Wing.
Directing the first episode is particularly notable because a premiere commonly sets visual language, pacing and the practical baseline for a series. In a fantasy adaptation, that can include the balance between physical performances, military settings and the presentation of fantastical elements such as dragons. It does not, however, confirm specific visual designs, episode counts, a release date or how closely individual story beats will follow the books. Those details have not been provided here, and Amazon declined to comment on Sakraya’s casting.
Liz Pelletier and Sherryl Clark will executive produce for Premeditated Productions, a sister company of publisher Entangled Publishing. Stefano Agosto, Outlier Society’s executive vice president of television, is set to co-executive produce. A co-executive producer typically holds a senior producing credit while operating beneath the executive-producer tier; the exact day-to-day responsibilities can vary from production to production.
A rapidly expanding book foundation
Fourth Wing began the Empyrean series with its release in May 2023 and became a New York Times bestseller. It was followed by Iron Flame in November 2023 and Onyx Storm in January 2025. September also brought Threshing Day, a novella containing 13 stories set in the Empyrean universe.
The planned fourth and fifth books have not yet received announced titles or release dates. That leaves the TV series with a published base of three main novels plus additional short fiction, but no confirmed television roadmap beyond the fact that the project has been ordered to series. Readers should be careful not to treat the existence of multiple books as proof of how many seasons the show will receive. A series order confirms a show is moving ahead; it does not itself reveal a multi-season commitment, a premiere window or an adaptation plan for every existing volume.
Still, the breadth of the existing material gives the production a defined fictional setting: Navarre, Basgiath War College, dragon-rider candidates and the consequences of Violet’s forced change in direction. It also gives the show a built-in audience with detailed expectations around the casting of Violet and Xaden. Casting announcements can invite immediate fan debate, but they offer only a first glimpse of a production that will ultimately depend on scripts, direction, performances and how its fantasy world is realized.
Why the Xaden role is a major early marker
For an adaptation of a character-led romantasy series, the principal pairing is a practical production milestone. It gives the creative team its two most visible on-screen anchors and gives audiences a clearer idea of the show’s intended ensemble. It does not reveal the finished chemistry between the performers, nor does it settle questions about secondary characters, dragons, costumes, creature effects or the show’s eventual schedule. Those are all separate parts of the adaptation process.
What it does establish is that Fourth Wing is assembling the personnel needed to translate a high-stakes fantasy premise into episodic television. Sakraya brings prior genre television experience through Warrior Nun and Tribes of Europa, while McGregor has the lead role of Violet—the candidate thrust into an institution where success means entering an elite order and failure can mean death.
There is an obvious overlap in audience appetite between Fourth Wing’s blend of perilous training and fantasy mythology and the ongoing interest in game worlds built around relics, gods and branching paths. For a separate example of that kind of fantasy-storytelling vocabulary in games, see our coverage of Fire Emblem: Fortune’s Weave’s expansion plans.
For now, the concrete update is straightforward: Emilio Sakraya is set to portray Xaden Riorson, opposite Esther McGregor’s Violet Sorrengail, with Averill steering the series and Joy directing its opening episode. The rest of the flight plan—including a release date and further casting—remains unannounced.
