Pegasus in a Dragon's Lair: 3D Render

Photorealistic 3D render of a majestic Pegasus inside a dragon's cavern. A pearly-white Pegasus with a luminous iridescent mane and large feathered wings stands on a jagged rock ledge; head held high, eyes bright, nostrils gentle. The dragon's lair around is cavernous with stalactites, mineral deposits, and a sprawling treasure hoard: gold coins, jewel-encrusted artifacts, ancient armor, and crystal formations. A glowing lava pool casts warm orange-red reflections on the Pegasus and rocks. Cinematic lighting with dramatic rim light along the wings, volumetric fog, and floating dust motes. Realistic stone textures, metallic treasure, and crystal facets rendered with PBR materials and ray-traced lighting. Camera at a dynamic 3/4 low angle to emphasize scale, 16:9 aspect. Mood: awe-inspiring fantasy realism.
