Photorealistic Castle Dungeon Altar at Dusk

Photorealistic scene of an ancient sacrificial altar in a damp castle dungeon. Rough-hewn stone walls etched with moss and lichen, dripping water, and iron torches in wall sconces casting warm amber light that flickers across grimy surfaces. A weathered stone dais supports a carved altar plate, a rusted ceremonial dagger, a brass chalice, and a ring of wax-draped candles; dried petals and faint dark stains suggest ritual use. Heavy iron chains and manacles hang on the walls. In the background, arched pillars fade into a dim archway and a grated window lets through a pale, foggy glow. The air feels cold and humid, with mist curling along the floor. View is slightly low-angle and close to the altar, with shallow depth of field, emphasizing highly detailed textures: chipped stone, carved runes, patina on metal, and wax drips. Color palette of cool grays and earthy browns illuminated by warm amber light, cinematic lighting, hyper-detailed photorealism, ultra-high realism.
