Raven in a Photorealistic Magical Library

A photorealistic raven with glossy black feathers perched on a carved wooden railing inside a magical library. Surrounding shelves tower with ancient leather-bound tomes, some books floating mid-air and glowing with faint runes. Warm candlelight and brass lamps cast amber highlights and soft shadows, while wisps of magical light and swirling dust motes drift through the air. The raven's eye reflects the flicker of a flame; its beak and feather detail are ultra-realistic with a subtle iridescent sheen. Background shows intricate carved arches, ladders, and a spiral staircase receding into softly blurred depths. Mood is mysterious, enchanted, timeless; textures include rich wood, leather, gold, and blue-violet ambient glow.
