Photorealistic Castle in a Volcanic Crater

Photorealistic depiction of a grand medieval castle perched inside the bowl of a volcanic crater. Steep basalt walls surround the rim, with steam vents and wisps of ash. In the crater's center a glowing lava lake bathes the scene in orange-red light, reflecting on wet stone and on armor. The castle features moss-covered stonework, crenellated towers, a sturdy keep, and a wooden drawbridge spanning a lava-fed chasm. Torches line the ramparts as banners flutter in a smoky breeze. In the foreground are scorched vegetation, pumice, and rising steam. Lighting is dramatic and cinematic: warm lava glow contrasts with cool cavern shadows and a dusky sky. High dynamic range, ultra-crisp textures on rock, moss, metal, and water; deep perspective with a slight tilt for epic scale; 8K realism.
