A black and white drawing of a skeleton surrounded by skeletons

Create an intricate, high-resolution 4K (UHD) illustration that closely resembles a page from a meticulously crafted demonology book. The illustration should vividly portray a malevolent entity cloaked in shadow, its form consisting of a grotesque arrangement of bones. These bones should be organized in a macabre fashion, with the faces of tormented souls intricately etched and drawn onto the surface of the bones. These imprisoned souls' expressions must bear the weight of their past sins, profound regrets, and agonizing screams of torment. The entire scene should be engulfed in an oppressive ambiance, conveying a sinister and eerie atmosphere, and the color palette should be strictly limited to shades of black and gray, giving the image a foreboding and spectral quality. Furthermore, emphasize the creature's own countenance, distorting it to the point of being utterly unrecognizable. This distortion should enhance the horrific nature of the entity and accentuate the chilling details of the bones and the imprisoned souls, making it a truly nightmarish vision. Please execute this prompt with meticulous attention to detail to create a truly haunting and evocative representation in the style of a demonology book, and ensure that the final image is in stunning 4K resolution (UHD).
