A black iron cauldron bubbles with bright green liquid in front of a stone fireplace. Its glow spills over the flagstones and the vapor rises in a thin curl. Corked jars of dried herbs and dark tinctures stand along the mantel and the stone ledge, next to a mortar and pestle.

An open spell book with a pair of round spectacles lies in the foreground. More worn leather volumes are stacked on the right, topped by another pair of glasses and a carved pumpkin. Small jack-o'-lanterns glow at several points in the scene. The thick, textured paint and warm browns are set off by the green of the potion.
