A highly detailed stone relief carving of a menacing skull. The skull has deep, cracked textures, giving it an ancient and weathered look. Surrounding the skull are intricate gothic patterns and mystical symbols, resembling an old temple engraving. The relief is chiseled into rough, aged stone, with shadows emphasizing the depth of the carving. The overall feel is dark, ominous, and mysterious, like something from an ancient cursed ruin.
