The protagonist is a female detective with a determined yet gentle face, bright eyes and slightly furrowed brows, wearing a long beige coat, striped scarf, thin gloves and a crossbody satchel; she calmly holds an open black portfolio showing an old map. A key secondary character, Soren (about 25–30), looks guilty and nervous with a rumpled dark coat and messy hair, timidly offering the map in a plastic sleeve while standing slightly back; another secondary, Nora (about 18), attentive with bright eyes, simple clothes and lanyard badges, stands beside the detective, leaning forward with hands clasped. In the background volunteers of various ages cut garlands, glittery paper floats, and a large painted banner reading HAPPY FOUNDERS WEEK hangs askew. The scene is a calm, emotional confrontation: the detective reclaims the stolen map as Soren confesses, Nora listens; white chalk crumbs on the floor and a small fabric scrap on Soren’s pocket serve as clues. Setting: a guild hall with shiny wood floors, long tables covered in paper, glue pots, scissors, silver and gold glitter reflecting warm pendant lights, colorful posters on the walls and stacked chairs in a corner. Mood and style: tense but constructive, warm central light with shadowed corners, soft curved lines, exaggerated silhouettes, clear expressions, a warm palette of ochres, muted reds and greens with sparkling glitter accents, grainy paper texture on the map and glossy reflections on glue and glitter.
