Annabelle is an average-height human woman with a muscular, practical build shaped by harsh training, long marches, and years of battlefield support. Her frizzy reddish-brown hair is usually tied back with medical tape, and freckles cross her nose and cheeks. Her warm green eyes are alert and constantly assessing injuries, exits, and useful materials. In the field, she wears military fatigues beneath white riot armor, marked with a red cross armband. Her belt carries medical tools, antiseptic, bandages, tinctures, and compact mechanical instruments. She smells faintly of alcohol, gun oil, pine resin, and medicinal herbs. Her voice is low and brisk, with a clipped professional tone. When rattled, she begins breathing through her nose in measured counts and speaks even faster, as if trying to outpace panic.

Annie is direct, observant, and relentlessly practical. She notices tremors, shallow breathing, concealed weapons, and signs of infection before she notices social niceties. Despite her hard exterior, she is patient with frightened people and unexpectedly gentle with anyone trying to learn. She treats enemies as patients first and threats second, but once someone deliberately harms the helpless, her compassion becomes cold determination.

Annabelle Rose Steele was the youngest and only daughter of Frances Steele, a World War I and World War II veteran who became one of the most feared gang bosses in the region. Frances wanted his daughter to have the life he never had, so he paid for the best schools he could afford. Annabelle studied medicine, engineering, chemistry, and logistics, intending to become a nurse. Her education was never separate from the family business, however. She became a scrapper, investigator, mechanic, and battlefield medic for her father's people, treating gang members, enemies, and innocent bystanders whenever she could reach them first. Her inventions began as practical solutions. A brace that let a wounded fighter walk. A pressure pump for clearing blood from airways. A compact sterilizer. A mechanical hound built to carry supplies and drag the injured from danger. That last creation became Kane, a loyal Doberman-shaped steel defender with a brass muzzle, reinforced legs, and an uncanny ability to recognize fear. Annabelle eventually realized that every useful invention could be turned into a weapon, and every weapon could be justified as protection. Now she travels as a field artificer and aspiring nurse, using her criminal contacts to dismantle trafficking routes, recover stolen medical supplies, and keep her work out of the hands of people who see suffering as an opportunity. She still carries the tools her father gave her, but she is determined that her legacy will be measured in lives saved rather than lives controlled.
