A dark, desolate futuristic cityscape with ancient ruined architecture, toppled buildings, broken statues, scattered debris and cracked pavement. The environment is lit by soft ambient moonlight or deep blue atmospheric lighting. The skyline is filled with destroyed high-rises and silhouette towers lost in mist. No humans, no machines, no glowing cores — only ruins and forgotten structures. The scene is post-apocalyptic, eerie, and quiet — meant to suggest a civilization long gone. Tileable elements, high-detail textures on stone and rubble.
