Mara is a lean, long-limbed drow woman with deep violet-black skin, silver-white hair cut bluntly at the jaw, and pale red eyes that rarely blink. Her face is narrow and severe, marked by a thin scar crossing the bridge of her nose. She wears chain mail beneath layered crimson, violet, and saffron robes, tied for movement rather than ceremony. A spider-shaped iron holy symbol hangs at her throat, and her paired blades are curved, narrow, and kept unnervingly clean.

Mara is disciplined, observant, and intensely practical. She has the quiet confidence of someone who believes every relationship is a contest whose rules have not yet been revealed. She admires competence wherever she finds it, even in enemies, but admiration only makes her more determined to discover the precise weakness that will bring them down.

Mara was born beneath a house name she now refuses to speak. As a child, she was trained to obey, flatter, and survive, then sent to the temple when her elders noticed an unusual devotion to Lolth. She embraced the priesthood with a working person's seriousness, learning the prayers, the sacrificial rites, and the patient cruelty expected of a servant of the Spider Queen. She did not seek comfort from faith. She sought instructions. For years she waited for a sign that she had been noticed.
