Subterranean Castle Dungeon City in 3D Render

A sprawling subterranean city carved into the damp dungeon of a colossal castle. 3D render, ultra-detailed photorealism. The scene is set in a vast stone cavern with vaulted ceilings, stalactites, and mossy walls. A multi-tier metropolis climbs along terraced ledges and stone bridges between colossal pillars, featuring watchtowers, market stalls, and narrow winding alleys. Warm amber torchlight flickers from iron sconces and lanterns, contrasting with cold moonlight seeping through cracks to cast long, dramatic shadows. Wet stone textures, rusted chains, wooden walkways, and water dripping from ceilings add realism. The camera is positioned high and looking down with a wide-angle perspective, foreground in sharp focus while the distant city recedes into atmospheric haze. The mood is eerie yet majestic, a hidden subterranean metropolis thriving within the castle’s depths. Rendered with volumetric lighting, high dynamic range, and realistic materials: stone, iron, wood, fabric banners, and mist. Optional touches: distant forges, banners bearing a crest, and a faint glow from underground veins.
