Callista Gearwright is a small, wiry gnome with an unmistakable air of eccentricity. Her wild Blond hair is perpetually frizzed, as though she’s been shocked one too many times by an experimental device (which she has). A streak of silver runs through one lock, a "souvenir" from an energy-core accident that left her more determined than ever.

Her large, blue eyes shine with curiosity, rimmed by dark circles that hint at sleepless nights spent tinkering. A thin pair of goggles sits perpetually on her forehead, the lenses smudged with soot and grease. Her rosy skin is marred with tiny nicks and burns from countless experiments gone awry, but she wears them like badges of honor.

Callista dresses in practical patchwork clothing adorned with pockets, straps, and utility belts brimming with tools, gears, and vials. A leather apron, charred at the edges, is secured over her tunic, and her boots are scuffed from endless hours scouring ruins. Around her neck, she wears a pendant crafted from a shard of Aetherheart's original core, glowing faintly with a soft blue light.

Aether is a sleek, clockwork beetle designed for utility and durability. Its tiny size allows it to scuttle into tight spaces, scout ahead, and serve as an extra pair of "hands" for Callista. Its glowing eyes double as tiny lanterns ideal for working in tight spaces, and its mandibles are capable of precise manipulation or a sharp bite if needed.
