Rhiannon Matthias Character Analysis: The Heart of the Squad in Iron Flame
Overview
Rhiannon Matthias emerges in Iron Flame as far more than a supporting player. She is Violet Sorrengail's closest friend, the newly promoted squad leader of Second Squad, and a rider whose signet—the rare ability to summon objects across distance—proves repeatedly that loyalty can be as tactical as any weapon. While Violet wrestles with venin secrets and Xaden's withheld truths, Rhiannon anchors the narrative's emotional core, modeling what trust looks like when the world demands suspicion.
Rebecca Yarros positions Rhiannon at the intersection of several thematic arcs explored throughout Iron Flame. Her presence tests questions the novel raises about trust and secrecy, the cost of sacrifice for the greater good, and the work of forging unity across divides. She is, in many ways, the squad's moral compass—not because she is naive, but because she refuses to let fear sever the bonds that keep riders alive.
Plot Role
Rhiannon's plot function is deceptively straightforward: she leads. After receiving her promotion to squad leader in Chapter Six, she immediately shoulders the responsibility of keeping eighteen cadets alive through an academic year that includes the classified Rider Survival Course, wyvern attacks, and the escalating hostility of Vice Commandant Varrish. Her decisions during the land navigation exercise in Chapter Fourteen exemplify her command style—she assesses threats like the rogue dragon Baide, positions riders to shield infantry, and delivers the brutal lesson that "that is why you don't fucking run" after a panicked cadet triggers lethal dragonfire.
But her role extends beyond battlefield tactics. Rhiannon becomes the keeper of Liam's letters when Violet entrusts them to her in Chapter Three, a symbolic act that places her at the center of the novel's grief and memory. She is the first person Violet tells when she discovers how to raise the wards. She organizes the squad gathering where Violet and the fliers negotiate the ethical dilemma of ward activation. In a story driven by classified truths, Rhiannon is the character who insists that difficult information must be shared—not hoarded.
Motivations and Traits Shown Through Actions
Rhiannon's defining trait is loyalty expressed through action rather than declaration. When Violet grows distant, consumed by secrets she cannot share, Rhiannon does not sulk. She confronts. During the land navigation exercise, she tells Violet directly: "You don't have to freeze out everyone you can't be completely honest with just because Riorson thinks that works for him." The observation is sharp, generous, and entirely characteristic—she names the problem without withdrawing her friendship.
Her summoning signet is an elegant metaphor for her relational role. In Chapter Twenty-Nine, when Varrish is about to discover the alloy-hilted dagger Violet carries, Rhiannon spontaneously summons it through a wall, saving Violet from exposure. The moment is dramatic, but its deeper significance lies in how Rhiannon's power works: she reaches across barriers to retrieve what is hidden. That is precisely how she operates in every relationship. She pulls Violet back from isolation. She draws the squad into cohesion. She retrieves trust when circumstances conspire to bury it.
Evidence from the text also reveals Rhiannon's quiet perceptiveness. She deduces Dain's memory-reading signet before Violet confirms it, noticing behavioral patterns others miss. She alerts Violet that the Healer Quadrant is hiding something involving Nolon and Varrish. These observations position her as an intelligence asset, not merely an emotional support.
Chronological Arc
Rhiannon's arc in Iron Flame traces a path from capable cadet to tested leader, with each challenge refining her authority.
Early chapters establish her as a steady presence. She accepts the squad leader promotion with the order to "Live," a word that carries weight after the losses at Resson. She stores Liam's letters, absorbing the emotional labor Violet cannot manage. When Violet confronts Xaden in the courtyard before his departure, Rhiannon hangs back, then celebrates her own news without demanding Violet's attention.
Mid-novel, the land navigation exercise tests her command. Facing Baide—the dragon of the slain Jack Barlowe—Rhiannon makes split-second tactical calls that demonstrate her growth. She orders riders to the front, infantries to guard healers, and keeps her squad from panicking. The exercise ends in failure, but her leadership does not.
The interrogation sequence in Chapters Twenty-Three through Twenty-Five places Rhiannon in direct physical jeopardy. She endures beatings alongside Violet, refuses to break under a truth-sensing signet, and participates in the squad's collective escape. Her composure under torture is not described as heroic posturing; it is simply the extension of her commitment to the people beside her.
Late-chapter events accelerate her responsibilities. When Violet confesses the truth about venin, Rhiannon forgives immediately and pivots to practical support. She organizes the townhouse meeting where Violet reveals the ward-raising plan to riders and fliers alike, framing the disclosure in terms of squad-as-family: "For riders, squads are more than a unit. We're family." The scene captures her arc in microcosm—she transforms private knowledge into shared purpose, then manages the fallout with her characteristic blend of warmth and steel.
By the novel's climax, Rhiannon stands beside Feirge as one of the six dragons needed to fire the wardstone, her presence the culmination of a journey that began with a simple promotion and ended with her becoming indispensable to the continent's survival.
Relationships
Violet Sorrengail. The friendship between Rhiannon and Violet is the novel's most reliable emotional anchor. When Violet isolates herself—training with Imogen, hiding her Archives research, refusing to confide—Rhiannon names the behavior without condemning the person. She says, in effect, I see you pulling away, and I'm still here. Their dynamic avoids the jealousy or resentment that a lesser narrative might manufacture. Instead, Yarros writes two women who understand that love sometimes means waiting for the truth rather than demanding it.
Rhiannon's summoning of the dagger in Chapter Twenty-Nine is the physical manifestation of this bond. She does not know what she is retrieving or why; she acts on instinct to protect her friend. The scene parallels earlier moments—her acceptance of Liam's letters, her confrontation during the land nav exercise—in which Rhiannon creates safety through presence rather than interrogation.
The Squad. As squad leader, Rhiannon manages the integration of first-years and, later, fliers into an existing unit. Her decision to assign study partners, organize shared meals, and enforce a "no blood on my sister's floor" rule during sparring reflects a leadership philosophy rooted in enforced proximity. She believes that shared experience breeds tolerance, and the novel validates this approach. The squad's cohesion during the interrogation escape and the wardstone negotiation owes more to her steady management than to any single dramatic gesture.
Xaden Riorson. Rhiannon's relationship with Xaden is indirect but significant. She never directly challenges him, but her choices offer an implicit critique of his secrecy. Where Xaden compartmentalizes information to protect people—a strategy Violet increasingly resents—Rhiannon insists that withholding truth is itself a form of endangerment. The contrast is sharpened when she organizes the townhouse meeting to tell the fliers about the wards. Xaden is absent, and the decision to disclose is Violet's, but Rhiannon's framing—"we're trusting you to do with this information what you will"—articulates a philosophy of transparency that stands in productive tension with Xaden's methods.
Key Decisions and Consequences
Accepting Liam's Letters. In Chapter Three, Violet passes Rhiannon the letters Liam left behind. The act is small but freighted with meaning: it establishes Rhiannon as the keeper of grief and memory, a role she will occupy for the rest of the novel.
Confronting Violet's Distance. During the land navigation exercise, Rhiannon challenges Violet about her secrecy. The moment could have fractured their friendship; instead, it becomes the foundation for Violet's eventual confession. Rhiannon's willingness to name the problem creates the conditions for honesty later.
Saving the Dagger. The summoning in Chapter Twenty-Nine is Rhiannon's most consequential single action. Without it, Varrish would have discovered the alloy weapon, exposing the weapon-smuggling operation and potentially destroying the rebellion. The signet's spontaneous manifestation—Rhiannon does not consciously control it—suggests that her magic is keyed to her deepest commitments.
Organizing the Disclosure. When Violet discovers that the wards require dragonfire, she goes to Rhiannon first. Rhiannon's response is immediate and practical: she arranges the squad gathering, manages the fliers' reactions, and frames the disclosure as an act of trust rather than a strategic calculation. The decision to include the fliers—borderline treason from a tactical standpoint—reflects Rhiannon's conviction that ethical leadership requires honest communication, even when it complicates operational goals.
Theme and Symbol Connections
Rhiannon embodies several thematic threads woven throughout Iron Flame. Her friendship with Violet illustrates the argument that love and vulnerability can coexist with strength—she is emotionally open without being weak, protective without being possessive. The squad's resistance to institutional corruption and propaganda relies on her ability to maintain cohesion when Navarre's leadership systematically isolates cadets.
Her summoning signet is a symbol made literal. In a novel about trust and secrecy, Rhiannon reaches across distance to retrieve what is hidden. She pulls the dagger through a wall, pulls Violet back from emotional withdrawal, and pulls the squad into unified action. The magic mirrors the character: it is not flashy or aggressive, but it changes outcomes precisely when they matter most.
The wardstone negotiation in Chapter Fifty-Two connects her to sacrifice for the greater good. Rhiannon does not make the decision—that falls to Violet—but she creates the forum in which the ethical dilemma can be honestly aired. Her insistence that the fliers "deserve to know" about the wards' effect on their channeling ability places her on the side of transparency, even when transparency risks the mission.
Five Questions About Rhiannon Matthias
1. What is Rhiannon's summoning signet, and how does it reflect her character?
Rhiannon's signet allows her to summon objects across distance, manifesting most dramatically when she pulls an alloy-hilted dagger through a wall to save Violet from exposure during Varrish's search. The signet aligns with her relational role: she retrieves what is hidden—objects, trust, the truth itself. In a novel preoccupied with secrecy, her magic is the mechanism by which concealed things re-enter the open.
2. How does Rhiannon respond when Violet keeps secrets from her?
Rhiannon confronts the distance directly. During the land navigation exercise, she tells Violet she notices the isolation and assures her she will wait for the truth. She does not guilt Violet, withdraw her friendship, or demand disclosure as a condition of loyalty. Instead, she names the problem and leaves the door open—a response that ultimately enables Violet's confession in Chapter Thirty.
3. Why does Rhiannon organize the squad gathering where Violet reveals the ward plan?
Rhiannon believes that squads are family and that survival depends on trust both on and off the battlefield. When Violet tells her how to raise the wards, Rhiannon immediately recognizes the disclosure's implications for the fliers and creates a neutral space where the information can be shared. Her framing—"we're trusting you to do with this information what you will"—emphasizes agency rather than coercion, embodying the forging unity across divides theme.
4. What role does Rhiannon play in the wardstone activation?
Rhiannon participates as Feirge's rider, one of six dragons needed to fire the Aretian wardstone. Her inclusion is narratively earned: she has been Violet's confidante, the squad's leader, and the person who ensured the fliers' voices were heard before the wards were raised. Her presence at the activation symbolizes the collective effort required to counter the venin threat—a contrast to the secrecy and individual burden that characterize much of the novel's conflict.
5. How does Rhiannon's leadership style differ from Xaden's approach to protecting others?
Where Xaden withholds information to shield people from danger, Rhiannon insists that transparency is itself protective. She discloses the ward plan to the fliers even though it risks operational security. She confronts Violet about her distance rather than letting it fester. This philosophical difference is never presented as a direct conflict—Rhiannon and Xaden operate in different spheres—but their contrasting approaches illuminate the novel's central question about trust and secrecy: does love protect by hiding the truth or by sharing it?
