A dark fantasy digital : A photorealistic 8K of Thog, the nightmare monster from Robert E. Howard's "The Slithering Shadow." The creature is depicted as a massive, amorphous entity covered in dark, textured skin that merges between reptilian and cephalopod qualities. It has several long, coiling tentacles stretching outwards, with each tentacle appearing to be alive with a mind of its own, grasping at the air menacingly. Its eyes are large, lidless, and glow a deep, hellish red, scattered randomly across its head, adding to its otherworldly terror. Thog’s mouth is cavernous, filled with uneven, jagged teeth coated in a dark viscous fluid. Drawn in a highly detailed style reminiscent of H.R. Giger and Zdzisław Beksiński, using vivid yet muted colors to emphasize the horror. The shot is a full body to focus on creature, with white background
