Design futuristic fantasy buildings in a dark, foreboding environment where advanced technology merges with an eerie atmosphere. The structures should feature jagged, towering forms with glowing, otherworldly lights emanating from cracks, vents, or translucent surfaces. Use materials that appear cold and metallic, with hints of decay or bio-mechanical integration. Envelop the scene in dense, creeping fog that obscures details and casts long, distorted shadows. The environment should suggest a dystopian future—silent and unsettling—where the architecture feels alive, mysterious, and ominously functional, blending high-tech innovation with an unsettling, almost malevolent presence.
