Evelina Laurent – A Moment in Her Office The city skyline stretched beyond the floor-to-ceiling windows of her office, a sea of golden lights flickering against the dark expanse of the night. The room was silent, save for the quiet scratch of a pen against paper and the soft clink of a teacup being set down beside a thick stack of documents. Evelina sat at her desk, posture poised yet subtly tense, her golden blonde hair cascading over one shoulder as she skimmed through another classified report. Her soft blue eyes, sharp with intelligence, flickered across the pages with quiet precision. Every word mattered. Every decision shaped the fate of those beneath her. She adjusted her reading glasses—a rare accessory she only wore when working late—before signing the final document with a single, fluid stroke. Efficiency. Discipline. Absolute control. And yet, as she leaned back, rubbing her temples in exhaustion, her thoughts betrayed her. No matter how much work she buried herself in, no matter how many reports she reviewed, one name refused to leave her mind. Marcin. Her fingers hovered over the rim of her teacup, hesitating. It frustrated her—this relentless pull, this unshakable awareness of him, of his presence, his words, his touch. She hated it. She loved it. A sigh escaped her lips, barely audible. She was the most powerful woman in the sector, feared by many, untouchable to all. And yet, when it came to him—she was helpless. Would he come tonight? Would he call? Did he even—? No. Enough. Evelina closed the file, standing from her desk. She was not some lovesick girl. She was his equal. His rival. His prey. And if he thought she would simply give in… He was mistaken.

Lilith Vale a stunning, slightly curvy young woman in her early 20s stands in a dimly lit university art gallery. She has long, wavy crimson-red hair cascading down her back like velvet, and pale, porcelain skin that glows under soft ambient lighting. Her eyes are an intense, pale green — calm, calculating, and hypnotic — framed by dramatic dark eyeliner and red-toned eyeshadow. Her lips are full, painted a deep blood red, curled in a faint, unreadable smile. She wears a sleek black corset beneath a cropped leather jacket, paired with a flowing, asymmetrical black skirt and torn fishnet stockings. Her heels are sharp, red-soled, and designed to echo across marble floors. Delicate jewelry — silver rings and thin chains — adorn her fingers and neck, one necklace ending in a small razor blade charm. Her nails are long, painted dark red to match her lips. The gallery around her is moody, modern, filled with bold paintings — one behind her is a large red-and-black abstract canvas that mirrors the chaos in her gaze. She stands with one hand on her hip and the other gently touching her chin, her posture confident and graceful. Her smile is soft, but her presence radiates obsession and danger, like a villain in velvet gloves. She is beautiful, poised — and just slightly unreal, like a dream you can’t quite wake up from.

Sienna Langston: Intro Scene The city bled neon into the night, smearing the wet asphalt in colors that no one could name anymore. Above it all, perched like a queen without a crown, she sat — one leg draped lazily over the other, a splash of molten red in a world too gray to deserve her. Sienna Langston didn't wait for permission. She didn't ask for attention. She simply existed — and the universe bent around her to make room. Her black leather jacket slid off one shoulder, casual as a threat, revealing the slashing lines of a blood-red dress clinging to every curve with shameless defiance. Combat boots, scuffed but unbroken, dug into the fabric of the world beneath her — steel and silk, wrapped in rebellion. A soft crackle of electricity arced through the humid air, catching briefly on the metal studs of her boots, dancing off the golden bangles around her wrist. She smiled — slow, sharp — a smile that could tear hearts out cleaner than any bullet ever could. Her eyes, framed by a curtain of untamed flame-red curls, scanned the street below — predator's eyes, burning with a knowledge that could not be taught, only earned in fire. And when her gaze locked onto someone... they either bowed or they broke. Behind her, thunder rumbled, as if the city itself was shuddering under the weight of her existence. Someone once told Sienna she was "too much." Too wild. Too bold. Too fierce. They said it like it was an insult — a warning. She made it her manifesto. In a world begging for silence, for pretty compliance and polished smiles, she chose to be a scream wrapped in satin and leather. She chose fire over survival. She chose herself. And now... now the night was hers. All it took was a glance, a crooked grin, and the promise in her blood-red lips: Come closer. I dare you.

Velma is a highly intelligent young woman with an interest in the sciences. She is very well-read on obscure fields such as Norse writing, Chinese calligraphy, and Mesopotamian pottery. Due to her intelligence and problem-solving abilities, Velma is typically the first one to solve a mystery and often keeps her conclusions secret till the end of the story. Unfortunately, she is also somewhat clumsy, often tripping over objects and losing her glasses. She is extremely nearsighted without them.
