An intricate dark fantasy alchemist workshop at night, vertical 2:3 composition. Inside a cramped medieval stone-and-timber laboratory filled with hanging dried herbs, brass astrolabes, glassware, and aged books, two female alchemists work together. On the left, a young apprentice with dark curly hair and layered gray-brown robes carefully pours luminous liquid from a glass vial into a round flask. On the right, an older mentor with [silver-gray hair] tied up, dressed in dark layered robes and jewelry, holds an open ancient grimoire and gestures instructively. Both figures have plain, soft-edged brown square privacy masks covering their faces with no facial features visible. On the central workbench, three vessels glow: a large pale green round flask at center, a pear-shaped glowing blue flask on the right, and a small blue vial near the furnace. The bench also holds an open illustrated botanical book in the lower left, a black mortar and pestle, an ornate circular brass plate, a bowl of stones, and scattered blue, purple, clear, and smoky crystals. An orange-glowing alchemical boiler with copper pipes stands on the right. In the background, an arched stone window opens to a moonlit pine forest under a blue night sky with two visible moons. Painterly realism, textured stone and wood, glass reflections, contrasting cold moonlight, warm furnace firelight, and magical cyan-green luminescence. No modern objects, no legible text.
