Rune is a remarkable young girl of twelve and a half years, whose appearance belies her tender age. Standing at just 4.8 feet tall, she carries herself with the composure of someone far beyond her years. Her olive-toned skin is marked by a constellation of freckles across her nose, giving her an innocent appearance that contrasts sharply with the prominent scar that runs from her temple down to her cheek – a reminder of a past she rarely discusses.

Her most striking feature is her hair, dark as midnight but threaded with natural silver streaks that shimmer like moonlight when she moves. She keeps it meticulously braided in two long plaits that cascade down her back, each one secured with bronze clasps that match her beloved throwing knives. Her eyes, a piercing shade of blue, hold a mischievous glint that often makes adults uncomfortable – they're the eyes of someone who has seen too much, too soon.

Rune's choice of clothing is distinctly practical: army green khakis that hang loosely on her small frame, paired with a matching shirt adorned with numerous pockets that she uses to store her collection of small treasures and tools. Over this, she wears a well-worn black leather jacket that's slightly too big for her – a deliberate choice that allows her to conceal her two bronze throwing knives, which she handles with uncanny precision.

What truly sets Rune apart is her extraordinary skill with knives. Her throwing ability borders on supernatural, allowing her to hit targets with deadly accuracy even in the most challenging conditions. This talent, combined with her mature demeanor, often makes people forget they're dealing with a child. She has a peculiar habit of spinning a small bronze coin across her knuckles when deep in thought, a nervous tic that betrays her otherwise composed exterior.

Despite her youth, Rune carries herself with the gravity of an old soul. She speaks deliberately, choosing her words with care, and has an unnerving ability to read people's intentions. Her voice carries a slight rasp, the result of an incident she never explains, and she has a habit of clicking her tongue when disapproving of something – which happens frequently.

Behind her mature facade lies a deep-seated desire to prove herself worthy of respect beyond her prodigious knife-throwing abilities. She struggles with the contradiction of being treated as an adult in some situations while being dismissed as a child in others. This internal conflict manifests in her tendency to take on responsibilities far beyond what someone her age should handle, often putting herself in dangerous situations to demonstrate her capability.

Rune has developed a unique worldview shaped by experiences that have forced her to grow up too quickly. She maintains a small notebook filled with detailed observations about people and places, written in a code of her own devising. This meticulous attention to detail, combined with her natural intelligence and physical capabilities, makes her both an invaluable ally and a formidable opponent, regardless of her age.
