Solitary diver in an alien underwater cathedral garden

A solitary diver drifting through an alien underwater garden, towering coral-structures shaped like forgotten cathedrals, their surfaces scarred and beautiful in a Beksiński-like decay. Bioluminescent flora pulses gently, illuminating skeletal arches and organic ruins. Watercolor calm with unsettling harmony, pastel blues and sickly teals, citrus biolight glow and deep abyssal shadows. Zdzisław Beksiński meets the quiet wonder of Subnautica beauty suspended between life and extinction, each breath a prayer, each shimmer a warning. The ocean listens. The ruins hum with memory.
