Thunderbird in an Ancient Library (Photorealistic)

Photorealistic image of a colossal thunderbird inside a grand, ancient library. The bird perches on a tall wooden ladder, wings partially unfurled, crest high, eyes piercing as if guarding ancient knowledge. Its feathers are hyper-real: deep indigo-black with iridescent blue-green highlights, each feather showing fine texture and a subtle, almost metallic sheen. Electric blue sparks trace along the wings and tail, crackling softly. Warm amber library light from brass lamps highlights the plumage and the carved oak shelves filled with leather-bound books and scrolls. A spiral staircase winds through the shelves; dust motes drift in sunbeams breaking through a large arched window. Beyond, stormy skies and a jagged lightning flash frame a stained-glass window depicting thunderbird imagery, adding dramatic backlighting. The mood is majestic and otherworldly, blending myth with knowledge. Cinematic lighting, ultra-high resolution, photorealistic rendering, natural color grading.
