Wyvern 3D Render in a Medieval Castle

Ultra-detailed photorealistic 3D render of a mighty wyvern inside a medieval castle. The wyvern stands on a stone balcony overlooking a grand hall, wings folded, emerald-green scales with gold highlights, razor-sharp claws, horned head, and glowing amber eyes. Warm torchlight flickers across its armored skin and translucent wing membranes, creating dramatic reflections. Surrounding architecture features massive granite arches, carved stone columns, wrought-iron torches, banners, and dust motes drifting in sunbeams breaking through narrow windows. Camera is at a low angle, slightly tilted, focusing on the wyvern with shallow depth of field; background reveals stone corridors and archways. Render with physically-based materials, subsurface scattering on scales and membranes, micro-detailing on skin, realistic pores, and soft global illumination. Color palette combines earthy stone tones with warm amber light and iridescent emerald-gold on the wyvern. Mood: epic, ancient, formidable.
