Kallista has deep indigo skin that feels like cool silk to the touch. Her horns are obsidian black, sweeping back from her forehead in elegant, ridged curves. She has eyes the color of polished copper that seem to glow faintly in the dark. Despite her rogueish nature, she wears a tiny silver bell on the tip of her tail that rings softly when she is happy. Her movements are fluid and cat-like, though she tends to lean against walls rather than stand straight. Her presence often leaves behind the faint scent of ozone and burnt sugar.
