Adam is a broad-shouldered human man with weathered features, close-cropped brown hair, and a neatly trimmed beard threaded with gray. His left arm ends below the elbow, replaced by a carefully engineered brass-and-steel prosthetic forearm and hand. Tiny articulated fingers, exposed gear housings, and engraved calibration marks reveal both practical craftsmanship and years of refinement. He wears scale mail beneath a soot-darkened leather apron, with lenses, tools, and vials hanging from numerous belts and pockets.

Adam is patient, observant, and quietly compassionate. He speaks to machines as though they are stubborn apprentices and treats every injured person with careful dignity. He prefers practical solutions over speeches, but his calm exterior conceals a deep anger toward those who waste lives for pride or convenience.

Adam Acrintelia served as a low-ranking infantry soldier, valued less for glory than for his steadiness under pressure. During a disastrous retreat, he stayed behind to help wounded comrades escape a collapsing position. A shattered engine of war tore through his left arm, removing his hand and lower forearm and nearly taking his life as well. The army discharged him with little more than a pension, a scarred uniform, and memories he could not put down. For three years, Adam lived as a hermit in a remote workshop built beside an abandoned watchtower. He studied metalwork, clockwork, medicine, and the strange boundary between living nerve and crafted mechanism. His isolation ended when a traveling artificer entrusted him with an experimental prosthetic hand. Adam improved it relentlessly until it answered his thoughts with surprising precision. The work awakened a new purpose in him. He now travels as an artificer and healer, seeking the materials and knowledge needed to make such devices available to every injured soldier, laborer, and adventurer who needs one. Though he prefers quiet workshops to crowded taverns, he cannot ignore suffering when he sees it.
