A close-up of a potion master in dim, atmospheric lighting, their face partially obscured by a hood. The figure is holding a glowing glass vial that contains a swirling cosmic texture—miniature galaxies, nebulae, and sparkling stars floating within. The vial’s light casts ethereal reflections of blues, purples, and silvers on their hands and face. Their eyes are intense and focused, as though peering into the secrets of the universe. Wisps of cosmic mist escape from the flask, shimmering faintly in the dim light. The blurred background features shelves filled with mystical ingredients, arcane tools, and faintly glowing runes, enhancing the sense of otherworldly alchemy in this intimate and detailed scene.
