Submersible Descending Into Mariana Trench Darkness

the prompt

A deep sea submersible descends slowly through the complete darkness of the Mariana Trench, its exterior floodlights the only illumination in an absolute black void. The camera sits at the nose of the vessel looking forward as strange bioluminescent creatures drift past, some never before seen, their bodies pulsing with cold blue and green light. The submersible reaches the trench floor and stirs up a cloud of ancient sediment. As the sediment settles, the lights reveal a massive structure on the ocean floor, unmistakably architectural, columns and archways covered in 10,000 years of marine growth. The submersible moves slowly along the facade. A mechanical arm extends and brushes decades of sediment from a carved relief on one of the columns. Beneath the sediment, a face. Human. Perfectly preserved in stone. Staring forward. The camera pushes in slowly on the carved face until it fills the frame completely. A single crack runs through it. Cinematic deep sea documentary aesthetic, extreme darkness with bioluminescent accent lighting, ultra-realistic water pressure atmosphere, tension-building ambient sound design, National Geographic meets ancient mystery visual language."
