Character analysis
Rhiannon Matthias
in Fourth Wing by Rebecca Yarros
Rhiannon Matthias is Violet Sorrengail's first and most loyal friend at Basgiath War College, acting as her emotional anchor and moral compass throughout Fourth Wing. A confident and sharp-tongued rider candidate from a military background, Rhiannon faces the harsh realities of the war college with practical courage instead of recklessness. She connects with Violet almost instantly during the perilous Parapet crossing, recognizing Violet's intelligence and resilience beneath her delicate appearance—a loyalty she maintains even as social and political pressures increase.
Rhiannon's journey revolves around growing trust and tested loyalty. Assigned to the same squad as Violet, she quickly becomes the glue that holds their friend group together, bringing in other cadets and boosting morale. Her bond with her dragon embodies her grounded and fierce spirit. Importantly, Rhiannon is one of the few individuals Violet confides in about the escalating threats tied to Xaden Riorson's rebellion secrets, proving her worth by standing strong instead of retreating to safer alliances.
Her key traits include fierce protectiveness, blunt honesty, and a knack for reading people accurately. She identifies manipulation—including Dain Aetos's controlling behavior towards Violet—before Violet herself fully recognizes it. Rhiannon also shows bravery in battle during the novel's intense combat scenes, holding her own against both wingleaders and venin-related dangers. She embodies the ideal of a chosen family forged in adversity: not born of blood or obligation, but built through intentional, repeated choices in the face of life-threatening challenges.
Who is Rhiannon Matthias?
Rhiannon Matthias arrives at Basgiath War College as a rider candidate with a military family background, practical intelligence, and a confidence that reads as hard-won rather than inherited. She is neither naïve enough to romanticize the college nor cynical enough to abandon its ideals entirely. From her first extended appearance during the Parapet crossing—the terrifying initiation walk across a narrow beam high above the ground—she distinguishes herself by choosing to engage with Violet Sorrengail not out of strategy but out of genuine recognition. Where most cadets see a general's daughter as too fragile to survive, Rhiannon sees someone worth knowing. That initial choice to extend friendship across social and physical danger establishes everything essential about her character: she is perceptive, loyal by intention, and unafraid to put skin in the game.
Her sharp tongue and blunt delivery never tip into cruelty because they are always aimed at truth rather than dominance. She calls things as she sees them—assessments of fellow cadets, of political dynamics within the wing, of people who claim to protect Violet while actually constraining her—and she does so without apology. This makes her one of the novel's most reliable moral registers.
What is Rhiannon Matthias's arc and motivation?
Rhiannon does not undergo a dramatic reversal or crisis of identity in the way Violet does; her arc is quieter and, in some respects, more demanding for it. She begins the novel committed to survival and honest solidarity, and she ends it having deepened those commitments at genuine personal cost. Her motivation is fundamentally relational: she wants a life in the Riders Quadrant that is built on chosen trust rather than coercion or political debt. The war college's brutality—its engineered attrition, its culture of domination—is the pressure she must resist without becoming hardened by it.
Her growth lies in expanding her circle of trust. Early in the novel, loyalty to Violet is her primary orientation. As the year progresses, she absorbs the trauma of losing squadmates, navigates increasingly dangerous secrets, and widens her understanding of who counts as an ally. By the time Violet begins drawing her into the orbit of Xaden's rebellion-connected network, Rhiannon's willingness to stand firm rather than seek safer alliances represents a mature, deliberate choice—the same quality she showed on the Parapet, scaled up against far higher stakes.
What are Rhiannon Matthias's key moments?
The Parapet crossing is the foundational scene. Rhiannon's decision to strike up a genuine conversation with Violet during the crossing—and to extend ongoing protection afterward—sets the terms of their entire relationship. It signals that Rhiannon evaluates people by demonstrated quality, not reputation or appearance.
Squad formation and social architecture: Throughout the early training chapters, Rhiannon functions as the connective tissue pulling together their squad. She mediates, recruits, and encourages, quietly building the chosen-family unit that sustains Violet through the novel's mounting dangers.
Her skepticism of Dain Aetos surfaces repeatedly in squad interactions and private moments with Violet. Rhiannon identifies his protective instincts as controlling before Violet is ready to name them, demonstrating an emotional acuity that functions almost as foreshadowing of Dain's eventual betrayal.
Liam Mairi's death is a shared wound that reorients Rhiannon's protectiveness into something grimmer and more urgent. The loss of a squadmate who served as a fellow guardian hardens her resolve without breaking her fundamental warmth.
Combat sequences and the venin-related dangers in the novel's later chapters confirm that Rhiannon's loyalty is not merely emotional support—she holds her own physically and tactically, backing her convictions with action.
What are Rhiannon Matthias's most important relationships?
With Violet, Rhiannon functions as the chosen sister that blood family cannot reliably provide. Their bond is reciprocal: Violet offers Rhiannon intellectual partnership and a cause worth the risk; Rhiannon offers Violet the unconditional acceptance that neither General Sorrengail nor Dain ultimately delivers.
With Dain, Rhiannon maintains a steady, low-temperature wariness. She never manufactures conflict, but she does not soften her assessments, and her consistent skepticism serves as a quiet corrective to Violet's residual affection for him.
With Xaden, her posture is one of cautious, evidence-based recalibration. She distrusts his reputation and power before gradually conceding him as a legitimate ally—a realistic arc for someone whose loyalty is earned, not assumed.
With Liam, she shares the complementary role of protector, and his death becomes a formative grief that sharpens her sense of what the college's dangers actually cost.
With Imogen, there is a guarded but developing mutual respect between two women who occupy analogous roles in separate circles—a relationship that mirrors the larger, tentative merging of Violet's world with Xaden's.
How is Rhiannon Matthias connected to the other characters?
- Violet Sorrengail
Rhiannon is Violet's closest friend and chosen sister at Basgiath. She befriends Violet during the Parapet crossing and consistently champions her throughout training, combat, and the revelation of dangerous secrets—offering the unconditional loyalty that Violet's formal relationships often fail to provide.
- Dain Aetos
Rhiannon is openly skeptical of Dain's influence over Violet, perceiving his protectiveness as controlling and self-serving long before Violet does. Her wariness of him creates low-level tension within the squad and foreshadows Dain's later betrayal.
- Xaden Riorson
Rhiannon is cautiously distrustful of Xaden at first, given his fearsome reputation as a wingleader and rebellion-marked rider. As Violet's bond with him deepens, Rhiannon watches closely, gradually accepting him as an ally rather than a threat to her friend.
- Liam Mairi
Liam is a squadmate and fellow protector of Violet, and he and Rhiannon operate as complementary guardians within their tight-knit group. His death is a shared trauma that deepens Rhiannon's resolve to protect those she loves.
- Jack Barlowe
Jack represents the predatory cruelty of Basgiath that Rhiannon stands against. His targeting of vulnerable cadets, including those in Violet's orbit, makes him a direct antagonist to everything Rhiannon values about solidarity and honor among riders.
- Imogen Cardulo
Imogen and Rhiannon occupy parallel roles as fierce, protective women within their respective circles. Their relationship is guarded but evolves toward mutual respect as the lines between Xaden's inner rebellion network and Violet's friends begin to blur.
Questions readers ask about Rhiannon Matthias
How do Rhiannon Matthias and Violet Sorrengail become friends?
Rhiannon befriends Violet during the Parapet crossing, the initiation walk across a narrow beam high above the ground. While most cadets dismiss Violet as too fragile to survive, Rhiannon engages in a genuine conversation and provides ongoing support afterward, driven by recognition of Violet's intelligence and resilience. This act of connection establishes the chosen-sister bond that anchors both characters throughout the novel.
Why is Rhiannon Matthias suspicious of Dain Aetos?
Rhiannon perceives Dain's protective instincts toward Violet as controlling and self-serving before Violet is ready to acknowledge them. Her wariness surfaces in squad interactions and private moments, creating tension within the group. Her skepticism, grounded in accurate character-reading rather than jealousy, functions as foreshadowing of Dain's eventual betrayal—making Rhiannon one of the novel's most reliable moral registers.
How does Liam Mairi's death affect Rhiannon Matthias?
Liam's death is a formative shared trauma that shifts Rhiannon's protectiveness into something grimmer and more urgent. She and Liam had functioned as complementary guardians of Violet within their squad, so losing him makes clear the real costs of Basgiath's dangers. The grief strengthens her resolve while maintaining her fundamental warmth, deepening her commitment to the chosen family she has built instead of leading her toward safer, less costly alliances.
What is Rhiannon Matthias's relationship with Xaden Riorson?
Rhiannon initially views Xaden with cautious distrust, wary of his fearsome reputation as a wingleader and rebellion-linked rider. As Violet's bond with him deepens and more dangerous secrets come to light, Rhiannon watches closely and gradually recalibrates, recognizing him as a legitimate ally rather than a threat to her friend. Her arc with him reflects her broader approach to loyalty: trust must be earned through evidence, not assumed based on reputation.
What role does Rhiannon Matthias play within her squad?
Rhiannon acts as the connective tissue of the squad—mediating conflicts, welcoming new members, and maintaining morale throughout the intense early training phases. Her blunt honesty and fierce protectiveness foster a culture of solidarity that consciously resists Basgiath's engineered competition and isolation. She is the architect of the chosen family that supports Violet and their squadmates under increasing pressure.
Does Rhiannon Matthias fight in combat, or is she primarily emotional support for Violet?
Rhiannon fulfills both roles: she offers crucial emotional and moral support while also standing her ground physically and tactically in the novel's intense combat sequences, including venin-related threats in later chapters. Yarros uses her to complicate the definition of a rider—showing practical courage grounded in solidarity instead of the reckless heroism that leads to many cadets' downfall. Her bravery is shown through actions, not mere performance.
How does Rhiannon Matthias's relationship with Imogen Cardulo develop in Fourth Wing?
Rhiannon and Imogen start with a guarded mutual wariness, each being fierce protectors within their respective circles—Rhiannon in Violet's squad and Imogen in Xaden's rebellion-connected network. As those worlds begin to intersect, their relationship evolves toward cautious mutual respect. The novel depicts them as analogous figures whose developing rapport mirrors the larger, tentative merging of Violet's friendships with Xaden's inner circle.
What motivates Rhiannon Matthias to stay loyal to Violet even as rebellion secrets make it dangerous?
Rhiannon's core motivation is to build a life at Basgiath based on chosen trust rather than coercion or political calculation. When Violet involves her in Xaden's rebellion secrets, Rhiannon's choice to stand firm rather than retreat to safer alliances reflects the same quality she displayed on the Parapet—now against much higher stakes. For Rhiannon, loyalty is a deliberate, repeated choice, which makes it particularly meaningful.
