A young female dwarf with unusually human proportions, standing upright at 4 feet 9 inches and carrying herself like a drilled infantry officer. Her armor gives her a broad, disciplined silhouette, but beneath it she is compactly muscular, with powerful shoulders, a narrow waist, and long forearms built for leverage rather than bulk. Her face is more human than most dwarves, with a straight nose, high cheekbones, and a small pointed chin, though her heavy brow and square jaw preserve a distinctly dwarven severity. Her copper-brown hair is braided into tight cords that disappear beneath her helm, while several loose strands constantly work free around her temples. She moves with controlled precision, never quite relaxing her knees. The unexpected detail is her hands, which are remarkably delicate and nimble, better suited to engraving jewelry than gripping a battlefield weapon. Within a minute of meeting her, most people notice that her eyes do not settle on faces. They travel to door hinges, ceiling joints, weapon belts, and the feet of everyone in the room.

Brunna is disciplined, observant, and quietly compassionate, but her compassion is expressed through preparation rather than comfort. She is generous with labor and stingy with trust. Around strangers, she is patient and almost ceremonially polite because she believes first impressions are evidence. Around family, she becomes controlling, interrupting and correcting them before they can make dangerous choices. In a crisis she is calm, direct, and brave. Afterward, when the danger has passed, she becomes restless and picks apart every decision she made. She wants to be seen as dependable, yet secretly resents how often everyone assumes she can carry one more burden.

Brunna was born in the lower foundries of Kharz Brag, a dwarven mining settlement built around a vertical shaft that descends through three layers of ancient stone. Her mother repaired mining braces, and her father kept the settlement's emergency ledgers. Brunna grew up learning that survival depended less on courage than on noticing what everyone else ignored. At seventeen, she joined the settlement watch after a support collapse killed twelve miners, including her older brother, Orsik. The official report blamed faulty timber, but Brunna discovered that the braces had been deliberately weakened to conceal an illegal excavation beneath the mine. During the investigation, she found her father's handwriting on one of the altered inspection records. He had falsified the report under pressure from the clan council, believing the excavation would secure the settlement's future. The discovery changed Brunna from an eager defender of tradition into a relentless skeptic of authority. She exposed the excavation, but the resulting scandal fractured her family and forced her to leave Kharz Brag. She now works as a caravan guard and structural inspector in surface settlements, quietly gathering evidence that the illegal dig uncovered something still alive beneath the mountain. Her current problem is that her younger sister, Torga, has followed her to the surface and joined the very smugglers Brunna suspects are transporting relics from the buried chamber.
