Edmund, a privileged member of a high-citizen family, serves as the deuteragonist and Loredana’s love interest. As the son of the powerful Headmistress Phillipa Prew, he’s born into immense wealth and power, but he rebels against the expectations of his caste by maintaining loyal friendships with low-citizens Jack Carroway and Dickie Langley, whom he has protected since childhood. His conflicting obligations inspire him to wield violence without hesitation to defend those he considers his own, and he also risks ridicule from callous peers who read his compassionate acts toward low-citizens as weakness or sentiment.

Edmund’s behavior in this regard marks his own personal quest toward Finding Connection in a Divided Society. Haunted by the controversial death of his grandfather, the Vanguard hero Ernest “The Hellion” Prew, he seeks to restore his family’s honor by recovering Ernest’s lost uniform in an attempt to prove that his grandfather didn’t flee from his final battle or die a coward. This goal leads Edmund to agree to a loveless, arranged engagement with Irene Hussey, who promises to give him his grandfather’s flight jacket in exchange. However, this engagement sits in open contradiction with his growing love for Loredana, a Green and the daughter of his family’s political enemy, Bruce Waldsten. Edmund’s relationship with Loredana forces him to confront the injustice of his world’s rigid divisions, and he begins to question his place within them. 

At the same time, he clings to a rigid perception of honor that compels him to endure his sister Rosamund’s psychological warfare and his mother’s blatant physical abuse. Notably, his refusal to retaliate against his mother’s abuse is a manifestation of his refusal to become the “beast” that she wants him to be. As the novel progresses, he engages in a quiet rebellion that gradually grows more public as his love for Loredana strengthens.

Charlotte, Loredana’s close friend, is estranged from the protagonist at the beginning of the novel, but once the two women reconcile, she becomes a major ally. Her journey is defined by loss, regret, and a desperate search for security and forgiveness. A year ago, she cut off her friendship with Loredana to immerse herself in the world of the Blues with her then-boyfriend, Jack. Now, her return to Loredana’s side shows that her loyalty, though compromised, was never fully extinguished.

Charlotte continues to struggle with the consequences of sabotaging her romance by attempting to cheat on Jack with Edmund, thereby losing both men’s regard. Because her own father has cut ties as well, she’s isolated and financially vulnerable, and when she rejoins Edmund’s entourage alongside Loredana, she’s once again targeted by Rosamund, who views the women’s proximity to Edmund as a threat. At the end of the novel, Charlotte rashly challenges Rosamund to a death duel that she can’t win. When Loredana saves her, the women’s friendship strengthens further, and she remains a loyal ally.

Rosamund repeatedly threatens Loredana and Charlotte, providing much of the novel’s conflict. As Edmund’s twin sister, she’s a high-ranking Blue who wields her status with casual cruelty, and she flouts the Bliss ban to feed her own addiction to the drug. Indulging in a possessive fixation on both her brother and Jack, she sees any woman who gets close to them as a rival to be eliminated. This jealousy drives her to viciously attack Charlotte and orchestrate Loredana’s public humiliation by leaking edited footage of Charles Blackwell’s death. 

Though she’s largely a static character, Rosamund’s intense need to control Edmund and Jack stems from her deep-seated insecurity and desire for affection. She, like Edmund, is subject to Phillipa’s physical abuse, and the novel suggests that her traumatic upbringing has warped her understanding of love. In the end, however, she embodies the moral decay and destructive entitlement of the Blue elite.

Bruce, father to Loredana and her sisters Vivian and Hillaire, is a loving father whose determination to ban Bliss and improve the lives of low-citizens make him a political firebrand. His political acts turn his family into targets for the vengeful Blue elite, complicating Loredana’s experiences at Grandmaster. As a Green Representative, he’s a man of strong convictions, but his paternal instincts often clash with his professional goals. For example, although he warns his daughters to be cautious and avoid Blues, his political actions repeatedly place them in harm’s way. His secret, long-standing friendship with the Blue President, Theodore Reeve, further complicates his public anti-Blue stance, revealing the subtle, hidden alliances that drive individual survival in the cutthroat world of politics.

His outlook on Bliss is shaped the death of his younger sister, Daisy, from a Bliss overdose. Throughout the novel, he mentors Loredana, but his lessons about the harsh realities of public life are insufficient to prepare her for the gauntlet that awaits her at Grandmaster. Yet despite his flaws, his decision to run for Governor of the Rainbow District reaffirms his unwavering commitment to fighting for a more just world, even at great personal risk.

Jack, Charlotte’s former boyfriend, is a member of Edmund’s entourage and has an alcohol addiction that arose in the aftermath of Charlotte’s betrayal. As a Green orphan, his life was transformed when Edmund took him and Dickie under his protection many years ago. His unwavering loyalty to Edmund often conflicts with his personal feelings, particularly in his fractured relationship with Charlotte. 

When Charlotte returns to Edmund’s entourage, Jack makes efforts to get sober, but just before the high-profile fencing duel between the Green and Blue Fraternities, he relapses, and his drunken state costs him the opportunity to duel. Though often cynical and guarded, Jack argues against the collective punishment of Heretic families and risks his own safety to protect Loredana and Charlotte. Although his arc remains unfinished at the end of the novel, the narrative implies that he must still undertake the difficult work of breaking free from his addiction.
