Shadera is a highly skilled assassin operating out of the impoverished Boundary ring of New Found Haven. Driven by the execution of her parents twenty years prior, she harbors a deep hatred for the ruling Veyra class and President Maximus. She accepts a dangerous contract to assassinate the president's son, viewing the job as symbolic retribution. Fiercely independent and prone to using physical violence, she actively resists emotional intimacy to maintain her focus.

Greyson is the son of New Found Haven's totalitarian president and serves as the state's official Executioner. Plagued by guilt over the murders he commits for the regime, he attempts to offset his complicity by secretly smuggling medical supplies to the outer rings. He views his privileged life in the Heart as a gilded cage and longs for freedom from his father's absolute control. His life fractures further when he is forced into an arranged marriage with the assassin sent to kill him.

Maximus is the totalitarian president of New Found Haven. He rules his city-state through systemic starvation, mass surveillance, and extreme brutality. In his private life, he subjects his family to severe physical and psychological abuse. He routinely uses violence against the women in his family to coerce obedience from his son, manipulating the lives of his citizens for political theater and absolute control.

Brooker is the eldest son of the Serel family. He is believed to have been murdered by a Daggermouth assassin prior to the events of the story. His violent death casts a long shadow over the Serel family, deeply wounding his younger siblings and fueling Greyson's resentment toward the rebellion in the outer rings.

Lira is Greyson's sister and works in public relations for the Heart. Having survived horrific sexual violence orchestrated by her own father, she has learned to navigate the extreme misogyny of New Found Haven's political sphere. She outwardly conforms to the regime's oppressive standards for women while secretly training in combat and plotting her own resistance against her father.

Callum is a powerful business owner who operates an illicit club in the Heart district. As Greyson's best friend, he provides a rare safe space for the Executioner to speak freely. He actively protects the sex workers in his employ and secretly gathers blackmail material on the Heart's elite. He maintains a careful distance from Lira despite harboring deep romantic feelings for her.

Elara is the wife of Maximus and mother to Greyson, Lira, and Brooker. She strictly adheres to the Heart's masking laws, keeping her face covered even during private family dinners. She endures severe, frequent physical abuse from her husband, occasionally intervening at great personal cost to protect her children from his violent temper.

Jameson is a skilled marksman and smuggler from the Boundary who operates under the rebel alias Ghost.

Driven by the loss of his sister to preventable illness, he works tirelessly at an understaffed clinic and heavily involves himself in the outer rings' resistance movement.

Jaeger is the leader of the Daggermouth assassins. Operating out of the Wolf's Head pub in the Boundary, he distributes contracts to fighters like Shadera and helps coordinate logistics for the local resistance movement against the Heart.

Captain Mikel is a senior officer in the Veyra army. He observes the elites of the Heart and carries out Maximus's orders, serving as a constant, intimidating reminder of the regime's surveillance state. He frequently interacts with Greyson, acting as both an enforcer of the law and an observer of the Executioner's behavior.

Moraine is a young woman from a prominent Heart family. Maximus initially arranges for her to marry Greyson as a political maneuver to solidify alliances and test his son's loyalty.

Maya is a sex worker operating under Callum's protection at Club Thane. She maintains a longstanding, familiar relationship with Greyson, offering him a brief respite from his stressful life.

Kestrel is a rebel leader based in the Cardinal, the middle ring of New Found Haven. She observes the regime's tightening grip on agricultural workers and attempts to coordinate resistance efforts with fighters in the Boundary.

Marcus is a Veyra sniper tasked by Maximus to surveil Greyson's apartment. He represents the ever-present threat of the Heart's secret police and possesses a dark history tied directly to Lira's past trauma.
