A breathtaking depiction of a submerged cathedral crafted entirely from crystal-clear glass. Sunlight pierces the ocean's surface, refracting into brilliant rainbows that dance across the cathedral's walls. Schools of shimmering fish swirl through the open spaces, and glowing coral encrusts the structure's base. The central altar is surrounded by spiraling streams of golden light. Shadows of whales and other sea giants glide through the distant water, evoking themes of serenity, spirituality, and the mysterious beauty of the deep.
