The queen's secret visit to the royal alchemist's study—a dark, mystical alchemy laboratory with a Gothic-style alcove, a wrought-iron-barred window, and shelves filled with glass flasks and vials of colorful potions, with books lying on the table. The center of attention is a beautiful young queen with refined, aristocratic features, large, expressive blue eyes, and captivating lips. She stands slightly turned, looking thoughtfully to the side with a hint of surprise. She wears a golden crown adorned with blue sapphires, a luxurious golden dress with a plunging neckline, a black velvet cape trimmed with fur, and gold jewelry with turquoise stones. Beside her, on a dark wooden table, stands a large, exquisite, golden butterfly-shaped automaton, crafted entirely of gold, with complex mechanics, gears, filigree, and a multitude of multicolored gemstones. The butterfly is mounted on an elegant gold stand with a large glowing glass bulb at its base, emitting a warm golden glow. In the shadows in the background stands an elderly royal alchemist with gray hair and beard, dressed in a dark blue robe with gold embroidery, watching the queen intently. Dramatic lighting, warm golden light from a single burning candle in the foreground and a bright, magical golden glow from the glass bulb at the base of the mechanical butterfly, beautifully illuminating the queen's wings, lower face, and chest. Additional cool, bluish moonlight pours from a tall window in the background. Deep, soft shadows fill the rest of the room. A high level of detail, realistic material textures, cinematic lighting, a mysterious and luxurious atmosphere—a masterpiece of the highest quality, ultra-detailed, photorealistic.
