The interior of a cosmic library grown inside a gargantuan, ancient tree on a floating island. The curved walls are living wood, intertwined with glowing mycelium networks that pulse with soft light. The ceiling is an open panorama of a swirling nebula in deep blues and purples, with real stars twinkling. Bookshelves are made of roots, and floating motes of starlight illuminate reading nooks. Whimsical, enchanting, Ghibli-esque, awe-inspiring beauty.
