An underwater photograph of a vibrant coral reef. Out of a deep trench, a large, translucent entity made of fragmented, glowing glass blocks slowly rises, looking almost like a forgotten deity. Schools of exotic fish scatter, and rays of sunlight filter down from the surface, creating complex refractions. Moody and mysterious, deep blue tones, natural bioluminescence, ultra-detailed rendering of glass and marine life. --ar 16:9
