Photoreal Wyvern in a Wizard's Tower Interior

Photorealistic wyvern perched inside a spiraling wizard's tower study. Textured stone walls with arcane runes carved into columns, shelves packed with ancient spellbooks, vials, brass instruments, and bubbling cauldrons. The wyvern has emerald-green and gold scales, a long serpentine neck, sharp horns, and amber eyes; wings folded along its back with intricate vein patterns on the membranes. Warm candle and crystal lighting cast dramatic highlights on its scales. A tall arched window pours moonlit blue-green light, revealing a starry night outside while dust motes drift in the air. Floating sigils glow softly as magical energy hums in the air. Parchments flutter on a stone table, and the air smells of old ink and ozone. Cinematic, photorealistic detail with realistic textures: rough stone, weathered wood, metallic trim, reflective scales, and moody depth of field; shot with a cinematic lens (85mm) to emphasize the wyvern and tower interior, conveying awe, mystery, and ancient power.
