A dramatic and atmospheric square image (1024x1024) suitable for an audiobook cover. The central focus is a detailed, intricate ancient Greek trident, glowing with an ethereal, deep blue light, partially submerged in dark, turbulent ocean water. Glistening water droplets and stylized, abstract waves surround the trident, suggesting immense power and depth. Hints of an ancient, submerged Greek ruin can be discerned in the background, subtly illuminated by the trident's glow. The overall color palette is dominated by deep blues, teals, and hints of gold or bronze in the trident's ancient metal, conveying mystery, danger, and historical significance. The lighting is moody and dramatic, with strong contrasts between light and shadow. The composition is centered and impactful, creating a sense of awe and foreboding. The style should be realistic yet slightly stylized, with a painterly quality and high detail, evoking a sense of epic adventure and ancient secrets.
