Futuristic Megacity Black Singularity AI Image Prompt

Create a vertical cinematic sci-fi cityscape showing a vast futuristic megacity at night in monochrome {argument name="color palette" default="black, white, and cold silver-gray"}. The viewpoint is a high aerial perspective looking down across an endless dense skyline of countless narrow skyscrapers, towers, and glowing city grids stretching to a hazy horizon. In the right-center foreground, place a colossal circular black void or artificial singularity embedded in the city, like a perfectly dark bottomless hole, surrounded by bright concentric rings of light trails that spiral around it like an accretion disk. The luminous rings should be made of many fine white and silver lines, suggesting extreme speed, orbital traffic, data streams, or gravitational distortion. Tall buildings cluster tightly around and beneath the vortex, with some needle-like spires rising above the light rings; emphasize intricate architectural detail, glowing windows, reflective metallic surfaces, and immense scale. The atmosphere should feel ominous, awe-inspiring, and futuristic, with mist, fog, bloom, and a soft bright horizon band under a dark sky. Use ultra-detailed photorealistic digital matte painting style, high contrast, deep blacks, volumetric haze, sharp skyscraper silhouettes, and cinematic lighting. No people, vehicles, signs, logos, or readable text.
