Identical twin halflings with striking sea green hair and large, dark, liquid eyes that sparkle with deep sea intelligence. Their skin is dotted with patches of delicate, iridescent silver scales that shimmer when wet. They have a lithe and muscular build from swimming. They wear matching thick, quilted coats over comfortable trousers, and often carry coiled nets and heavy harpoons suited for aquatic hunting.

Kayleigh and Kendra are inseparable and intensely nurturing. They possess a quiet, watchful nature typical of those who grew up in the shadows. They speak softly, often finishing each other's sentences, and move with a synchronized grace. While they are fierce hunters of the deep, their hearts are overwhelmingly kind, dedicated entirely to the comfort and safety of their adoptive mother.

Born to a superstitious sailor who saw their silver scales and aquatic nature as a curse, Kayleigh and Kendra were abandoned on the docks of a bustling coastal city at a tender age. They survived by hunting in the city's murky harbor and navigating the dangerous alleys, becoming expert urban and aquatic scouts. Their lives took a turn for the better when they were purchased from a harsh workhouse by the benevolent Claire Capstone. Though Claire was once a wealthy woman, her mind had regressed, leaving her in a vulnerable state of mental childhood. The girls immediately recognized a kindred soul in her vulnerability and took on the role of her protectors. Over the years, the master-servant dynamic dissolved into a deep, filial love. They now travel with Claire, treating her like their own sick mother. They provide her with constant care, assisting with bathing, feeding, and medical needs, viewing her not as a burden but as their greatest treasure. To avoid unnecessary stops and maintain her dignity during their travels, they have adopted unconventional habits including wearing protective padding themselves to stay focused on the journey ahead.
