A cluttered, dimly lit medieval alchemist's laboratory filled with shelves of glass jars containing strange specimens, glowing potions, and dried herbs. In the center, a cauldron bubbles with green smoke that forms the shape of a dragon. An old wooden table is covered with star charts, parchment scrolls, and brass instruments. Candlelight flickers, casting long, dramatic shadows. Moody atmosphere, oil painting style reminiscent of Rembrandt, rich colors, high contrast, volumetric lighting.
