Underwater Alien Ruins

Slow descending shot: The camera sinks through deep ocean water, descending past schools of bioluminescent jellyfish that illuminate the depths in soft pulsing violet and teal. Below, the massive outline of an alien ruin emerges from the darkness: geometric structures with impossible angles, covered in barnacles and coral but clearly artificial. Strange symbols etched into obsidian surfaces glow with a faint amber light that pulses in rhythmic patterns. A colossal archway frames a dark interior from which a warm golden light emanates. Marine life has colonized the structures: anemones wave in the current, small fish dart between crevices. Particulate matter floats through the water, catching the bioluminescent glow. The scale becomes apparent as a whale passes in the far background.
