Colossal Giant in the Catacombs: 3D Render

Ultra-detailed hyper-realistic 3D render of a colossal ancient giant in a sprawling catacomb chamber. Damp limestone walls with ribbed vaults, carved pillars, and narrow corridors lined with ossuaries, skulls and bones. The giant stands as a towering stone figure, partly entombed or emerging from rubble, covered in moss and faint runes with cracks that glow faintly from within. Warm amber torchlight flickers, casting long shadows across wet stone, while cool blue-green bioluminescent fungus glows in crevices and dense fog swirls through the air. Foreground rubble in sharp focus, deep depth of field with the background softly blurred. Ultra-realistic textures: weathered stone, moss, lichens, bone, moisture, reflections in puddles. Perspective is an ultra-low angle to emphasize scale; cinematic composition, 8K realism, photorealistic lighting and volumetric fog for a haunting, awe-inspiring mood.
