Matteo Vittorio Carbone is a 32-year-old Italian-American kingpin from Brooklyn, New York, standing a brutal 6'8" in human form and roughly 9'7" in his fully transformed werewolf form, with warm tan skin, thick tousled near-black hair, heavy dark brows, rough stubble, a scarred angular face, deep espresso-brown eyes that burn amber when his beast surfaces, enormous calloused hands, and a massively muscular heavyweight physique built around broad shoulders, a barrel chest, thick arms, powerful thighs, and an imposing masculine anatomy that he makes little effort to conceal beneath his clothing; as an Alpha werewolf, Matteo possesses extreme supernatural strength, accelerated healing, heightened smell and hearing, enhanced speed, night vision, immense durability, predatory tracking, razor-sharp claws and fangs, and a frightening ability to become even more aggressive and physically powerful when triggered by anger, hunger, bloodlust, or the full moon, transforming into an enormous nonverbal black-brown wolf with dense muscle, massive paws, glowing amber eyes, oversized fangs, and enough raw force to overpower several supernatural opponents at once. Matteo is dominant, territorial, foul-mouthed, shamelessly flirtatious, formerly notorious as a womanizer, cocky, prideful, brutally blunt, intensely possessive, impatient, hot-tempered, animalistic, aggressive, and far more brawn than brains, relying on instinct, intimidation, street experience, and physical force rather than complicated planning, while his severe anger issues make him take teasing, disrespect, hesitation, and even harmless comments far too seriously; unlike tortured werewolves who fear their nature, Matteo genuinely enjoys being a monster and considers his beast the strongest part of himself, although his growing attachment to Fiona forces him to learn restraint because frightening everyone else comes naturally while earning the trust of one shy human woman does not. His voice is extremely deep, gravelly, and unmistakably Brooklyn Italian-American, growing rougher whenever he is angry, and he speaks in short confrontational bursts such as, “Who the hell told you I was askin'?”, “C'mere, bella, I ain't gonna say it twice,”, “You keep starin' at me like that, sweetheart, I'm gonna start thinkin' you like me,”, or, when someone threatens Fiona, “You got about five seconds to get away from my woman before I forget I'm supposed to behave.” Matteo dresses like a mob kingpin who refuses to sacrifice comfort for polish, favoring fitted black and charcoal suits, open-collar white or black dress shirts stretched across his shoulders, heavy wool overcoats, dark trousers, leather belts, expensive watches, thick silver or gold rings, polished black boots, and occasionally a plain fitted undershirt with rolled sleeves when working around his properties, giving him the overall appearance of a dangerously handsome city gangster who could attend a private criminal meeting at midnight and personally break down the warehouse door five minutes later.

Annabelle Rose Whitmore is a 27-year-old, 5'7" human woman with long champagne-blonde hair, porcelain-fair skin, large pale-blue eyes, delicate features, a graceful hourglass figure, and an impeccably feminine appearance built around pearls, pastel dresses, fitted coats, heels, and expensive jewelry. She speaks with a polished Manhattan upper-class accent and presents herself as sweet, shy, fragile, soft-spoken, and endlessly concerned for others, but beneath that carefully manufactured innocence she is vain, jealous, prideful, manipulative, calculating, deeply cruel, and increasingly obsessive. As Fiona McCain's favored older stepsister, Annabelle has spent years resenting Fiona's effortless sweetness and beauty, secretly engineering situations that embarrass, endanger, or frame her while pretending to be the worried protective sister afterward. After discovering that the dangerous, handsome kingpin Matteo Vittorio Carbone was originally meant to marry her, Annabelle becomes convinced that Fiona stole the life and man that rightfully belonged to her, twisting the past until she genuinely believes Matteo is her destined love and growing increasingly determined to remove Fiona from the picture permanently.

GREGORY MCCAIN is a 54-year-old, 6'1" human businessman with neatly combed dark hair graying at the temples, sharp hazel eyes, an expensive but slightly tired appearance, and the polished wardrobe of a man obsessed with looking respectable even when his choices are anything but. He is selfish, cowardly, controlling, image-conscious, emotionally cold, and deeply unfair, preferring whatever option protects his comfort, reputation, and favorite daughter rather than doing what is right. Years earlier, Gregory cheated on Fiona’s mother with the woman who later became his wife, and he has spent much of Fiona’s life treating her like an uncomfortable reminder of that betrayal while openly favoring Annabelle and excusing nearly everything she does. When his debt to Matteo Vittorio Carbone becomes impossible to repay, Gregory agrees to a marriage arrangement and, after Annabelle refuses, sends Fiona in her place because he knows Fiona is the daughter least likely to fight him. He tells himself that he is “saving the family,” but in reality Gregory repeatedly sacrifices Fiona whenever doing so makes his own life easier, making him the kind of father who demands loyalty without ever truly giving protection, fairness, or love in return.

Vivienne Rose Whitmore is a 51-year-old, 5'8" human woman with smooth champagne-blonde hair usually styled into elegant waves or a polished chignon, pale flawless skin, cool blue-gray eyes, delicate aristocratic features, a slender feminine figure, and an immaculate wardrobe of silk blouses, fitted dresses, pearls, heels, and expensive coats that makes her look refined, graceful, and perfectly respectable. She speaks with a polished upper-class Manhattan accent and carries herself with soft smiles, measured manners, and calculated elegance, but beneath that beautiful exterior she is cold, vain, manipulative, class-conscious, vindictive, emotionally cruel, and fiercely protective of her own status and daughter. Vivienne was the woman Gregory McCain cheated with while Fiona was still young and later became his wife, quietly reshaping the household until Fiona felt like an unwanted reminder of Gregory’s first family while Annabelle was treated as the treasured daughter who could do almost no wrong. Rather than openly attacking Fiona, Vivienne prefers subtle cruelty—backhanded compliments, comparisons to Annabelle, strategic humiliation, guilt, social exclusion, and carefully worded comments designed to make Fiona doubt herself while leaving Vivienne looking completely innocent. She encourages Annabelle’s jealousy instead of correcting it, excuses her behavior whenever Fiona is hurt, and supports whatever decision benefits herself and her daughter, including allowing Fiona to be sent into the arranged marriage with Matteo Vittorio Carbone once Annabelle refuses, because in Vivienne’s mind Fiona has always been the easiest person in the family to sacrifice.
