Crystal Entity in the Clockwork City

Hyper-detailed 3D render of a luminous crystal entity floating in a sprawling clockwork city. The city is a labyrinth of brass gears, copper pipes, steam vents, and towering clock towers linked by cog-lined streets. The crystal is multifaceted, emitting a soft blue-green glow while refracting light into a rainbow spectrum that dances across nearby metallic surfaces. Warm amber gaslamp lighting contrasts with the crystal's cool refracted light. Add light rain for reflective puddles, subtle mist, and steam. Camera slightly below eye level with a dramatic focal length, shallow depth of field, and crisp micro-details on the entity and foreground gears. Realistic textures, metal wear, subsurface scattering in the crystal, volumetric fog in the distance.
