Antiga bibliotecária élfica em uma biblioteca de árvore luminosa

An ancient library hidden inside a giant hollowed-out tree, filled with floating books and glowing scrolls. Scene: the tree's interior is vast, with spiral staircases of living wood wrapping around the walls, shelves carved into the bark holding thousands of books, and a grand desk at the center. Subject: an elderly librarian — a wise, ancient elf — with spectacles and a staff, floating a glowing book from a high shelf with a gesture. Important details: visible book spines, glowing scripts, mossy wood textures, soft magical light from the books themselves, tiny glowing moths fluttering between the shelves. Lighting: warm golden light from the books, soft ambient glow from the ceiling (bioluminescent moss), cozy and serene. Use case: fantasy concept art for a game setting. Constraints: photorealistic, magical atmosphere, no watermark.
