A highly detailed illustration of a mysterious poison bottle displayed prominently on a crowded potion stall. The bottle is dramatically different from the others — it has a sinister, elegant design with jagged glass edges, deep green glowing liquid swirling inside, and a black wax seal dripping down its neck. An ominous symbol (like a skull or serpent) is etched into the glass or dangling from a thin chain. Around it, more mundane potions in various vials and flasks sit in wooden crates or shelves — colorful, bright, and ordinary in comparison. The lighting is moody, with shadows falling over the stall, but a shaft of greenish light subtly highlights the poison bottle, giving it an eerie glow. The environment is a medieval-style apothecary market, with textured cobblestone ground, old cloth canopies overhead, and rough wood beams supporting the stall. Textures are vivid — condensation on glass, rough cork stoppers, worn labels, and aged wood grain. The art style should be dark fantasy realism, reminiscent of game concept art or a scene from The Witcher or Dark Souls. Cinematic contrast, high dynamic range, and painterly brushwork with extreme attention to lighting and materials
