Mystical Underwater Cavern

This image illustrates a serene underwater cavern, where a giant, luminescent pearl floats above a rocky altar. The pearl is perfectly spherical, glowing with shades of soft blue and iridescent white, illuminating the cavern with a gentle, otherworldly light. The water is a deep cerulean, with shafts of light piercing through from the surface, casting ethereal patterns on the cavern walls. In the foreground, colorful corals and seaweed sway gently, adding to the serene ambiance. A lone diver, silhouetted against the pearl, hovers nearby, adding a sense of exploration and awe. The style is reminiscent of a fantasy seascape, with a focus on tranquility and the mysterious beauty of the ocean depths.
