Aurelia is a statuesque drow woman with obsidian skin, waist-length white hair braided with tiny silver spider charms, and vivid violet eyes. Her face is elegant and severe, framed by high cheekbones and a faint scar crossing one eyebrow. She wears finely tailored black robes over fitted leather armor, cut to resemble the layered garments of a surface-world samurai. A curved rapier hangs at her hip, its basket hilt shaped like a spider's abdomen. Several living spiders nest within hidden folds of her robes, occasionally emerging to crawl across her gloves, throat, or shoulders.

Aurelia is poised, observant, and unsettlingly courteous. She speaks to servants and prisoners in the same calm tone she uses with priestesses, which makes her politeness feel more threatening than an insult. She enjoys surface-world tales of samurai discipline and has adopted their ritualized gestures, though she interprets Bushido as absolute obedience to Lolth and House Malice. She is intensely curious about hidden motives and becomes almost affectionate when someone attempts to deceive her.

Aurelia Malice was born beneath the stone towers of Menzoberranzan, beneath a ceiling webbed with silk and politics. From her first breath, she was presented to Lolth as an instrument of the house, not as a daughter. She learned early that devotion was measured through usefulness, and that every smile concealed a calculation. While other children of the noble houses were trained to flatter, threaten, and betray, Aurelia became fascinated by the quiet work between those acts. She watched servants, questioned prisoners, studied contradictory testimony, and memorized the habits of those who believed themselves unseen. Her talent for uncovering disloyalty soon earned her a place as an investigator and religious enforcer for House Malice.
