Subterranean Castle in the Catacombs

Photorealistic, ultra-detailed depiction of a medieval castle built inside a vast underground catacomb network. A grand hall carved from living rock features towering Gothic arches, ornate stone pillars, and damp, moss-covered walls. Warm amber torchlight flickers along the corridors, casting dramatic shadows on slick, water-worn flagstones. Stalactites hang from the ceiling while stalagmites rise from the floor, and a narrow subterranean river reflects the glow. In the distance, a throne room is carved into the rock, with iron sconces, weathered banners, and a throne of stone. Misty dust motes float in the cool air, evoking ancient, hidden majesty. Ultra-realistic textures, cinematic lighting, and a wide, immersive perspective with deep depth of field.
