Briana Matthews in Oathbound: Character Analysis

Overview: The Scion Who Chose Her Own Cage

Briana "Bree" Matthews enters Oathbound as a protagonist in crisis. She is a Legendborn Scion of Arthur who, at the end of the previous book, made a desperate bargain with the Shadow King to save her friends. That bargain, and the incomplete debt it leaves behind, becomes the engine of her story. The novel opens with the Shadow King's magic engulfing her on a hill above the Northern Chapter's Keep, and from that moment forward, Bree is removed from the world she knows and thrust into a brutal, isolated apprenticeship under a demon king who has stolen her memories of everyone she loves.

This analysis traces Bree's arc from captive to weapon to self-possessed survivor. It distinguishes between what the text explicitly establishes and what readers may reasonably interpret. The central tension of her character is not whether she will gain power—she does, rapidly—but whether she can reclaim the parts of herself that power was meant to protect.

Plot Role: The Bargained Scion

Bree's role in Oathbound is twofold. First, she is the narrative's emotional and physical center, enduring the Shadow King's training while the rest of the cast searches for her. Second, she is the story's key to the Shadow Court's politics. The Shadow King—revealed early on to be Erebus Varelian, a demon who murdered the real Erebus and impersonated him for years—does not simply want a student. He wants a weapon. He tells her as much after she surrenders Excalibur, vowing to build her into something he can use.

Her disappearance ripples through every other plotline. William Sitterson, the Scion of Gawain, refuses to leave the Northern Chapter's Keep without her. Mariah and her aunts work to protect Alice Chen, who lies in a coma-like stasis. Nick Davis engineers his own arrest to secure a sanctioned quest to hunt the Morgaines, partly to survive assassination attempts and partly to act against the Council's corruption. Selwyn Kane, consumed by demonia after feeding on Bree's root, becomes a threat his own mother must contain. Bree is, in effect, the absent center around which the entire novel's conflicts orbit.

Motivations and Traits Shown Through Actions

Bree's primary motivation is control. She has lost her mother, her memories, and her sense of safety, and she refuses to lose anything else. When Erebus presses her on what she wishes to become, she answers with a triad of goals: untouchable, unstoppable, and impervious. Her stated reason is that her power and pain must belong to her. This is not a passive wish; it is a survival strategy born from grief and repeated violation.

Her actions throughout the training arc demonstrate a fierce, sometimes reckless determination. She sprints into a forest with a ten-minute head start, knowing the cambion twins will hunt her using only their aether sense. She fights them when they catch her, releasing root that engulfs their heads in flames. She forges her first construct—a purple protective dome—under the threat of a lightning strike, surviving the blow. She kills a goruchel demon on her first night of field practice, driving a blade through its chest and watching it die. These are not the actions of a passive victim; they are the actions of someone actively choosing to become dangerous.

At the same time, Bree's emotional vulnerability remains visible beneath her hardening exterior. She feels envy watching a couple on the street, wondering if she once had a connection like theirs. She feels guilt when she thinks of the Merlin boy who sacrificed himself for her, and longing for the boy who ran after her as she left. She hides her silver curl—the mark of Arthur—in a braid, aware that it marks her as something the world will try to claim. Her toughness is real, but it is also a shield.

Chronological Arc: From Captive to Ruthless

Bree's arc in Oathbound can be divided into four phases.

Phase One: The Bargain and the Abduction (Chapters I–II)

The novel opens with Bree standing on a hill as the Shadow King's magic engulfs her. She recalls her recent losses: Volition's destruction, her friends' compromised refuge, Alice in a coma, and Selwyn fallen to demonia. The King takes her hand and transports her through shadows to a windowless corridor, revealing himself as Erebus Varelian. He explains that Nick would not have let her leave, and promises no one will find her. In London, he demands Excalibur. When she resists, he reminds her that her incomplete bargain leaves her owing him a debt, threatening Selwyn, Alice, Nick, and her father. She surrenders the sword to a goruchel named Agaraz. The King returns empty-handed and vows to build her into a weapon.

This phase establishes the power dynamic. Bree is not a willing student; she is a debtor. Her compliance is coerced, and the threat against her loved ones is explicit.

Phase Two: The First Lessons (Chapters II–VI)

Bree arrives at Erebus's home, where she learns he murdered the real Erebus and has been impersonating him. She is confronted by the cambion twins, Zoelle and Elijah, who mistake her for tribute. Erebus reveals they are his wards and sets her first lesson: she must learn to seal her power so demons cannot detect it. The twins hunt her, and when they attempt to consume her root, her bloodmark awakens and burns them. Erebus explains that the bloodmark binds a human to a debt and marks them as claimed. He alters its spellcraft so he can sense her root levels at any distance.

In her first formal training session, Erebus demands she forge a construct. She creates a sword, but he insists on something defensive. He presses her on what she wishes to become, and she resolves to become untouchable, unstoppable, and impervious. When he asks what she will sacrifice, she silently answers: anything. The world goes black.

This phase is defined by loss. Bree wakes to discover that a day has passed and her memories of living people have been erased. She cannot remember her father's face, the boy she kissed, her best friend, the Merlin boy, or the boy she ran from. Erebus denies manipulating her memories, claiming the loss was unexpected. He offers a truth-telling agreement and questions her about oaths she has made to herself. She forges her first protective dome and survives his lightning strike. He declares her untouchable and says they are ready to begin.

Phase Three: The Weapon in Training (Chapters 14–31)

Three months pass. Bree hunts lesser demons with the twins, kills an imp with a knife forged from her Bloodcraft, and reflects on the nature of her memory loss. She understands that her personal history remains intact, but the identities of living people have been erased, leaving only emotional impressions. She remembers the dead clearly—murdered boys named Russ, Whitty, and Fitz, and a man named Martin Davis—but the living are gray, misty shapes.

She bonds with the twins during a night at a demon bar, where they share personal revelations about attraction. She encounters a Black girl with golden eyes and the scent of root magic in a bathroom, a girl who has been beaten and is clearly being trafficked. Bree wants to help her but is pulled away by the twins, who fear Erebus's punishment. This moment crystallizes her growing unease with her situation.

When the twins learn that another Shade, Mikaelaz, holds the King's crown, they infiltrate an auction at Mikael's estate. Bree descends to the basement to steal the crown, blinds security cameras with her power, and fights a masked thief who can dissolve her root constructs. The thief recognizes her and calls her by name. He stages a romantic scene to escape detection, introducing himself as Benedict Pierce and her as his fiancée, Iris Bauer. Bree does not recognize him, but the reader understands this is Nick Davis on his quest.

Phase Four: The Reckoning (Chapters 50–60)

Bree regains consciousness in an underground cell with Mariah, Zoe, and Nick. Lawson, their captor, reveals himself to be Erebus in disguise. He explains that he was investigating the Regents for the Merlin deaths, using the Lawson alias to monitor events. He manipulated Bree and Zoe into retrieving his crown, hoping a Morgaine would unlock it. He learned the Regents are targeting Rootcrafters. He praises Bree and Zoe for their loyalty, then leaves them imprisoned, inviting them to attempt escape.

In the final confrontation, Bree faces Erebus directly. She uses her power to restore her memories, choosing to reclaim her soul even at the cost of losing something else. When she lets the King go, he collapses back into Erebus's body, bloodied. He tells her she has become ruthless, after all. The novel ends with Bree reunited with her father, Nick, and the others, but the cost of her transformation is left ambiguous.

Relationships: The People She Lost and Found

Bree's relationships in Oathbound are defined by absence and recovery. Her memory loss means she experiences her closest bonds as emotional impressions rather than concrete identities.

Erebus Varelian / The Shadow King: Her captor, teacher, and antagonist. He is manipulative, cruel, and genuinely invested in her development as a weapon. Their relationship is a twisted mentorship built on coercion and debt. He removes her memories, alters her bloodmark, and uses her to retrieve his crown, yet he also teaches her to control her power. The text leaves his ultimate motives ambiguous, but his final lesson—that she has become ruthless—suggests he succeeded in shaping her.
The Cambion Twins (Zoelle and Elijah): Initially hostile, they become Bree's closest companions in captivity. They bond over shared vulnerability and honest answers about attraction. Zoe, in particular, reveals that she and Elijah live in fear of Erebus's punishment, hinting at a shared trauma that Bree only begins to understand.
Nick Davis: The boy she ran from. Bree retains only a feeling of longing for him. Their reunion at the auction is charged with unrecognized intimacy. When her memories return, she feels every emotion she had started to nurture at Penumbra blossom fully, and she sees that Nick had yearned for her as she had for him.
Alice Chen: Her best friend, in a coma-like stasis. Bree's memory of Alice is reduced to worry. When she finally sees Alice again, she is afraid she won't feel what she should. The fear dissipates when she sees Alice's sleeping face, and she holds her hand, whispering her name.
Selwyn Kane: The Merlin boy who sacrificed himself for her. Bree retains guilt. Selwyn consumed her root, which caused his demonic state. His mother, Natasia, later reveals that Bree is his Scion of Arthur, and that Bree's mother Faye was Natasia's true Scion. Selwyn's fate is a direct consequence of Bree's power, and his hunger for her is a thread that runs through the novel.

Key Decisions and Consequences

Bree makes several pivotal decisions in Oathbound, each with significant consequences.

Surrendering Excalibur: When Erebus threatens her loved ones, Bree gives up the sword. This decision saves her friends in the immediate term but leaves her in the King's debt and without her primary weapon. It also sets the stage for her entire captivity.
Vowing to Become Untouchable: When Erebus asks what she wishes to become, Bree answers with a triad of goals and silently agrees to sacrifice anything. This decision shapes her training and her identity. It is both a declaration of self-possession and a surrender to the King's methods.
Choosing to Restore Her Memories: In the final confrontation, Bree uses her power to reclaim her memories, even though the cost is the loss of something else. This is her most important decision: she chooses her humanity over the cold, controlled power Erebus offered. The text suggests this is what makes her truly ruthless—not because she is cruel, but because she is willing to suffer for what she loves.

Theme Connections

Bree's arc connects directly to the novel's central themes.

Identity and Self-Possession: Bree's memory loss is a literal loss of identity. Her journey is about reclaiming who she is, not just what she can do. Her vow that her power and pain belong to her is a statement of self-possession in the face of systemic exploitation. See the identity and self-possession theme page.
Oaths, Debts, and Bargains: Bree's entire situation stems from an incomplete bargain. The bloodmark that binds her is a physical manifestation of debt. Her story explores what it means to owe someone your power, and what it costs to break free. See the oaths, debts, and bargains theme page.
Power, Exploitation, and Systemic Corruption: Erebus exploits Bree's power for his own ends, just as the Regents exploit Rootcrafters. The vials labeled "BM" (Bree's blood) found in the Institute's labs show that the Order is trying to replicate or neutralize her power. Bree is a target of systemic corruption on multiple fronts. See the power, exploitation, and systemic corruption theme page.
Sacrifice, Grief, and Transformation: Bree's transformation into a ruthless fighter is born from grief. She sacrifices her memories, her comfort, and ultimately a part of herself to become what she needs to be. Her arc is a study in how grief can either consume or transform. See the sacrifice, grief, and transformation theme page.
Legacy, Bloodline, and Inheritance: Bree is the Scion of Arthur, and her bloodline carries a power furnace claimed by Erebus through her ancestor Vera's bargain. Her silver curl marks her as Arthur's heir. Her story is about inheriting a legacy of violence and deciding what to do with it. See the legacy, bloodline, and inheritance theme page.
