Pegasus in a Damp Underground Tunnel

A hyper-realistic depiction of a majestic pegasus standing in an underground tunnel. The tunnel is carved from damp gray rock with rough surfaces, occasional stalactites, and rivulets of water running along the walls. Sparse yellow-orange conduit lights along the ceiling cast warm pools of light and long, dramatic shadows across the scene, reflecting off the pegasus's glossy white coat and iridescent wings. The wings are large and detailed, each feather rendered with realism, while the mane and tail flow as if stirred by an unseen breeze. The pegasus gazes forward with luminous eyes. Dust motes float in the stale air, and a thin fog clings to the ground where wet gravel and puddles mirror the light. In the center of the tunnel, parallel rails fade into a distant vanishing point, emphasizing depth and scale. The overall mood is awe-inspiring and mysterious, with photorealistic textures on fur, feathers, damp rock, metal rails, and subtle weathering. High-resolution, cinematic lighting, and a sense of grandeur that makes the tunnel feel vast behind the mythical guardian.
