Characters
Salem Salazar
Salem Salazar is a deeply complex and determined young woman, marked by a mixture of intellectual curiosity, emotional vulnerability, and personal trauma. At just twenty years old, she is studying criminology at Mortimer University, driven not only by academic ambition but by a haunting family past—her sister Olivia’s mysterious disappearance and presumed death on a beach.
Salem carries the heavy burden of her family’s scandalous history, which shapes her desire to redeem their name while grappling with her own isolation and mistrust. She possesses a sharp forensic mind, able to dissect crime scenes with clinical precision, but beneath this rational exterior lies a wounded soul haunted by claustrophobia and past traumas, such as being trapped in a coffin at a funeral.
Her interactions with peers are tinged with wariness, shaped by betrayals, yet she also yearns for connection and trust. Throughout the story, Salem’s emotional journey is defined by her growing bond with Cazimir van der Waal, a relationship that challenges her guarded nature and draws out both her vulnerabilities and fierce determination.
Her investigative drive is relentless, fueled by a need to uncover hidden truths behind a series of student deaths and her sister’s fate, intertwining her personal and academic worlds in a dangerous quest for justice.
Cazimir “Caz” van der Waal
Cazimir van der Waal, often called Caz, is an enigmatic and brooding figure whose presence is as magnetic as it is intimidating. A post-graduate artist at Mortimer University, Caz carries a turbulent past and a hidden agenda that anchors much of the narrative tension.
His tattoos and muscular physique give him a striking, almost mythic appearance, and his artistic talent is deeply intertwined with his emotional state, using his creativity as an outlet for rage, pain, and passion. From the moment he first encounters Salem at the beach crime scene, she becomes his muse, reigniting a creative fire that had been extinguished by loss and frustration.
Caz’s demeanor oscillates between protective intensity and dangerous volatility; his relationship with Salem is fraught with tension, desire, and mutual challenge, revealing layers of trust and mistrust. Beyond his personal struggles, Caz is entangled in a shadowy world of secret societies, surveillance, and power struggles on campus, indicating a larger role in the mysterious forces shaping Mortimer University.
His protective instincts toward Salem grow as he becomes increasingly invested in their shared mission and emotional connection, even as he battles his own demons and the looming threat of betrayal.
Dr. Merlin
Dr. Merlin emerges as a charismatic but potentially sinister figure whose influence permeates the darker undercurrents of Mortimer University.
As a psychology professor closely linked to Salem’s sister Olivia’s past, Merlin carries an aura of manipulation and hidden menace. His interactions with Salem are laced with subtle threats and psychological games, underscoring his role as an antagonist wrapped in academic prestige.
His possession of Olivia’s stolen pendant and a suspicious scar on his face add to the mystery and suspicion surrounding him, suggesting deeper involvement in the deaths and disappearances haunting the university. Merlin’s leadership in the cruel Mortemian cult and connection to violent initiation rites further paint him as a figure of danger and control, wielding his position to maintain a web of secrecy and terror within the student body.
Aditi
Aditi serves as a vital ally to Salem, representing warmth, resourcefulness, and a pragmatic approach to navigating Mortimer University’s complex social and institutional hierarchies. As a scholarship student, she contrasts with the privileged backgrounds of many peers but commands respect through her intelligence and social connections.
Aditi’s alliance with Salem brings essential support in uncovering hidden truths, accessing restricted databases, and confronting the university’s dark secrets. Her presence softens some of Salem’s isolation and provides a grounding friendship amid the suspense and danger surrounding the main characters.
Through Aditi, the narrative explores themes of loyalty and courage within a hostile environment.
Melissa
Melissa is a friend of Salem’s who becomes a direct victim of the university’s sinister forces, highlighting the stakes and brutal realities lurking beneath Mortimer’s elite facade. Her capture by the Mortemian cult and subsequent rescue by Caz underscores the tangible threats faced by the characters and the violent, secretive rituals that tie into the broader conspiracy.
Melissa’s ordeal personalizes the danger for Salem and strengthens the urgency of their fight against the cult and its leaders, adding emotional weight and human vulnerability to the narrative’s darker elements.
Selina Salazar
Selina Salazar, Salem’s mother, is portrayed as a dignified and emotionally complex figure, embodying both the pain and resilience of the Salazar family legacy. Her warmth and elegance reveal a side of Salem’s upbringing that contrasts with the latter’s earlier feelings of isolation and mistrust.
Selina’s interactions at the gala with Salem’s friends and Caz hint at a family history steeped in both tragedy and social stature, emphasizing themes of heritage and redemption. Though emotionally distant at times, Selina’s presence underscores the generational impact of the family’s scandals and losses, and her eventual approval of Salem’s relationship with Caz suggests hope for healing and unity.
Eric and Baron
Eric and Baron represent antagonistic forces within the university’s social and power structures. Eric is volatile and aggressive, engaging in tense confrontations with Caz, while Baron is cunning and manipulative, actively investigating and threatening both Caz and Salem.
These characters embody the dangerous political and social currents swirling around Mortimer, where rivalries and secret agendas threaten to engulf the protagonists. Their presence heightens the story’s suspense and underscores the peril inherent in the protagonists’ quest for truth and survival.
Themes
Trauma and Its Lingering Impact
Trauma forms a foundational undercurrent throughout Enigma by RuNyx, deeply shaping Salem’s motivations and worldview. The novel presents trauma not simply as a past event but as a living force that colors Salem’s present and future.
Salem’s sister Olivia’s mysterious disappearance and presumed death on a beach haunt Salem’s psyche, fueling her obsession with uncovering the truth and seeking justice. This traumatic family history manifests in Salem’s complex relationship with her own identity and the burden of her family’s scandalous reputation.
The trauma is compounded by the subtle but relentless way it isolates Salem socially and emotionally, making her wary of trust and connection. The novel carefully explores how trauma engenders a protective emotional armor, evident in Salem’s icy demeanor and her reluctance to form deep bonds despite her yearning for companionship.
The claustrophobia and panic attacks she experiences reveal the physical embodiment of trauma’s psychological grip. Importantly, trauma in Enigma is not static; it resurfaces in the unfolding investigation, with every new death or secret echoing past wounds.
Salem’s journey is a painful negotiation between confronting trauma head-on and protecting herself from its consuming power. The narrative also explores how trauma intersects with institutional failures—the university’s history of unexplained deaths and cover-ups intensifies Salem’s sense of danger and mistrust, underlining the theme of trauma’s pervasive, often systemic nature.
Power, Secrets, and Corruption
Mortimer University, with its historic prestige and hidden elite networks, serves as a microcosm of power structures riddled with secrecy and corruption. The theme of power is explored through the insidious ways authority is wielded behind closed doors—whether through secret societies, academic hierarchies, or clandestine rituals.
Salem’s investigation reveals layers of institutional corruption that enable violence and silence victims, reflecting a world where appearances mask darker realities. The university’s legacy, steeped in tradition, acts as a smokescreen for exploitation and cover-ups, suggesting that power often protects itself by controlling narratives and erasing inconvenient truths.
The novel scrutinizes how power dynamics shape relationships, with Salem navigating social hierarchies that favor privilege and suppress dissent. Figures like Dr.
Merlin and Baron symbolize the menacing enforcers of this corrupt order, manipulating students and instilling fear. Caz’s involvement with secret societies highlights the ambiguous nature of power—where it can be both a tool of oppression and a weapon for resistance.
Through Salem and Caz’s intertwined paths, the story examines the cost of challenging entrenched power and the risks involved in seeking transparency. The persistent secrecy and shadowy dealings underscore the theme that knowledge and truth are contested territories, with dire consequences for those who dare to uncover them.
Identity, Isolation, and Belonging
Salem’s personal journey is deeply tied to questions of identity and the human need for belonging, which is complicated by her family’s tainted reputation and her own trauma. She grapples with a fractured sense of self, torn between the desire to distance herself from her family’s dark past and the undeniable connection to her sister’s unresolved fate.
This internal conflict is mirrored externally in her social interactions at Mortimer University, where academic excellence and lineage dominate, making true belonging elusive. Salem’s isolation is palpable—not just physical, as she often stands apart from peers, but emotional, as she struggles to trust and open up.
Yet, moments of tentative connection, such as her friendships with Aditi and Melissa, and her complex relationship with Caz, reveal a yearning to break through loneliness. The novel presents identity as fluid and contested, shaped by past experiences but also by choices and relationships forged in the present.
Salem’s evolution throughout the narrative—from guarded outsider to someone willing to forge deep bonds—reflects the tension between self-protection and vulnerability. The theme extends to the university environment, where group psychology, secret societies, and rituals speak to the human drive for inclusion, often at a high cost.
The costs of belonging are explored through Salem’s navigation of social games, betrayals, and alliances, suggesting that belonging can be both empowering and dangerous.
The Duality of Art and Darkness
Art serves as a complex symbol and narrative device within Enigma, embodying both creation and destruction, beauty and pain. Cazimir “Caz” van der Waal, as a tortured artist, personifies this duality.
His artwork, especially the collection inspired by Salem, translates inner turmoil and trauma into powerful, evocative images that capture both vulnerability and strength. Art here is not merely aesthetic; it acts as a form of communication beyond words, revealing hidden emotions and truths that characters struggle to express.
This artistic expression stands in stark contrast to the darkness permeating the story—murders, rituals, and psychological manipulation—but also connects to it intimately. Caz’s art becomes a channel for processing grief, rage, and desire, underscoring the therapeutic yet dangerous edge of creativity born from suffering.
The motif of the “Painter” at the crime scene, as well as Caz’s mysterious presence on campus, symbolizes how art and violence coexist, blurring lines between muse and monster, creator and destroyer. The story uses this duality to explore how individuals cope with trauma and chaos through creative outlets, and how art can be both a refuge and a weapon.
Moreover, the secret societies’ involvement and the ominous rituals hint at a darker, almost mystical connection between art and power, where creativity is intertwined with control and manipulation.
Love, Trust, and Vulnerability
The evolving relationship between Salem and Caz is central to the emotional fabric of the story, presenting love as a complex, fragile, and transformative force. Their connection is marked by mutual attraction, intellectual sparring, and deep-seated wounds that both hinder and draw them closer.
Love in Enigma is not portrayed as simple or idealized; it is fraught with mistrust, secrets, and the scars of past betrayals. Yet it is precisely through this vulnerability and imperfection that their relationship gains depth and realism.
Both characters grapple with their fears—Salem’s guardedness born of trauma, and Caz’s chaotic, nomadic existence and dangerous affiliations—highlighting the difficulty of building trust when surrounded by danger and uncertainty. Their intimate moments blend physical desire with emotional tension, illustrating how closeness can be both healing and threatening.
The narrative also explores how love intersects with power dynamics and personal agency, as both struggle to maintain autonomy while leaning on each other for support. Ultimately, the theme emphasizes that love can be a source of strength and hope amid darkness, but it requires courage to break down walls and accept imperfection.
Through Salem and Caz, the novel portrays the fragile beauty of human connection in a world shadowed by mystery and danger.
