A high-quality anime illustration in a medium shot, 3/4 view, depicting Adelheid von Luger, an imperial female knight and first lieutenant, walking along the night wharf of the Imperial Free City of Lübeck in a fantasy world inspired by the Holy Roman Empire. Adelheid is a noble woman with long, flowing silver hair and piercing indigo eyes, wearing a detailed imperial military uniform consisting of a structured midnight-blue tunic with gold braided epaulettes, a white officer's shirt, and polished black leather boots. She carries a mithril silver magic sword sheathed at her waist, her right hand resting lightly on the hilt as she strides forward with a dignified and resolute expression. The environment is a dark, atmospheric harbor at night, with wooden piers, docked merchant ships of the Hanseatic League, and the distant silhouette of medieval city spires under a starry sky. The lighting is moody, with warm lanterns casting long shadows and shimmering reflections of moonlight on the dark water, creating a sophisticated and solemn atmosphere with a rich, deep color palette.
