"A solitary and ominous Black Plague Doctor stands in a dimly lit, narrow cobblestone alleyway in a medieval European city. The doctor is clad head-to-toe in their iconic, dark, heavy protective gear: a long, oil-soaked waxed canvas or leather coat, dark gloves, and a wide-brimmed black hat. Their most striking feature, the beaked mask with dark, glass eyeholes, is prominent, creating an eerie, bird-like silhouette that conceals their face entirely. A wooden cane or pointer is held firmly in one gloved hand. The atmosphere is heavy and foreboding. The background features dark, crumbling stone or timber-framed buildings with shuttered windows, hinting at a city under quarantine. Smoke or mist might subtly swirl around their feet. The lighting is stark and dramatic, perhaps from a distant lantern or a sliver of pale moonlight, casting deep shadows and highlighting the grim details of their attire. The overall mood is one of profound isolation, historical dread, and silent vigilance against an invisible enemy."
