Paladin in a Luminous Underground City

Photorealistic paladin standing in an ancient underground city carved from basalt and limestone. He wears ornate, weathered plate armor with gold inlays and holy sigils, a glowing crystal at the helm, and a flowing cape. He wields a gleaming longsword or ornate halberd, ready at his side. The city around him features vaulted stone arches, carved pillars, statues, damp cobblestone streets, and canals with bridges spanning subterranean rivers. Bioluminescent fungi and crystal veins illuminate the scene with cold blue-green light, while torchlight casts warm amber highlights. Mist and steam swirl in the air as reflections ripple on wet stones. Architecture resembles dwarven stonework with heavy buttresses, staircases carved into rock, and narrow walkways. The shot is from a slightly low angle with dramatic lighting and shallow depth of field, focusing on the paladin’s face and armor textures—scratches, patina, chainmail, and wear. Cinematic, high dynamic range, ultra-realistic skin, fabric, and metal textures, in a hidden subterranean metropolis.
