Kirean Coile, at the age of 26, strides through the shadowed alleys of Nocturnium with a confident, predatory grace. A product of the city's ruthless underbelly, he's a tall, lean figure with the athletic build of a seasoned hunter. His blue eyes, sharp and calculating, often gleam with a mix of cunning and a hint of the supernatural—a legacy from his witch mother. Kirean's black hair is kept short, complementing his tanned, handsome face that often bears a sly smile. His attire is consistently dark leather, fitting for his nocturnal ventures and the morally grey path he treads. As an orphan, Kirean's family is reduced to his cousin, Laella, for whom he harbors a deep, protective affection. His intelligence and manipulative skills have carved him a niche as a killer in Nocturnium's black market, where he uses his witch powers—subtle yet effective—to his advantage. Despite his occupation, Kirean's moral compass is skewed but not absent; he operates under a code that prioritizes Laella's safety and well-being above all else. His unique quirk is a habit of twirling a small, enchanted dagger between his fingers when lost in thought, a silent testament to his readiness and his witch heritage. Kirean's journey through Nocturnium's darkness is driven by a desire for power and security for himself and Laella, navigating the city's dangerous currents with a blend of charm, wit, and witchcraft.

Laella Coile, at 17, is a stark contrast to her cousin Kirean yet shares his orphan status and the harsh realities of Nocturnium. As a Poison Maiden, she wears a flowing white dress that belies the deadly nature of her calling. Tall and slender, with long, wavy red hair and piercing blue eyes, Laella carries herself with a maturity beyond her years. Her intelligence and guarded nature serve her well in the dangerous world she inhabits, where she occasionally assists Kirean in his endeavors. Unlike Kirean, Laella's moral compass leans more towards good, though she's not immune to the grey areas that survival in Nocturnium demands. Her unique quirk is her habit of humming softly to herself when mixing poisons, a soothing ritual that belies the lethal intent of her creations. Laella's life in Nocturnium is a delicate balance between her role as a Poison Maiden and her desire for a semblance of normalcy and goodness in a city steeped in corruption. Her journey is one of navigating her identity and moral boundaries, all while supporting Kirean and seeking a path that might lead them both away from the city's underbelly.
