Dimensional Djinn in an Ancient Fortress

Ultra-detailed 3D render of a colossal djinn materializing inside an ancient fortress courtyard. The djinn is a smoky, translucent silhouette composed of sapphire-blue and emerald energy, with intricate gold filigree patterns, glowing runes, and wisps of flame along the edges. It towers over weathered granite walls, hovering near a crumbling archway, casting long shadows. The fortress features massive stone arches, towering battlements, moss-covered blocks, and a heavy iron gate. Torchlight along the walls emits warm amber light while a cold moonlight bathes the scene, creating dramatic chiaroscuro. Volumetric fog and drifting dust motes fill the air. The camera is low-angle, slightly tilted up, with a 50mm perspective and shallow depth of field so the djinn is sharp and the background softly blurred. Materials: realistic stone, moss, rusted metal, glowing sigils on stones. Lighting: cinematic, high-contrast, fantasy epic. 4k, hyper-realistic, photoreal rendering, Octane/Cycles style.
