Prompt
A massive deep-sea horror lying coiled in a trench, partially buried in the ocean floor. Its body is serpentine and covered in barnacle-like growths, glowing scars, and ancient markings. Only part of it is visible—a huge eye with no pupil, a fin-like spine, and a ridge-lined face with tendrils. The surrounding water is black and filled with floating particles. Bioluminescent fog drifts through the trench. The creature looks ancient and godlike, too large to fully comprehend.
