Photorealistic Star Shining in a Damp Dungeon

Photorealistic scene of a glowing star resting on a damp dungeon floor inside a medieval stone chamber. The star is crystal-like with sharp facets, emitting an icy blue-white light that spills across wet flagstones, creating reflections in puddles. Flickering torchlight from wall sconces casts warm amber contrasts on rough mossy stone walls, rusty chains, and an iron gate. Dust motes drift in the air as a looming archway and crumbling masonry fade into the background. Captured in ultra-detailed realism with dramatic chiaroscuro, volumetric light, and shallow depth of field that keeps the star in razor focus while the background remains softly blurred.
