Enchanted Treehouse Library with Mythical Creatures

A majestic, ancient tree has been transformed into a multi-level library and observatory, complete with spiral staircases, glowing windows, and a telescope. The scene is illuminated by a twilight sky filled with stars and nebulae, with magical butterflies fluttering around. At the base of the tree, a unicorn drinks from a glowing pool, a griffin rests nearby, and a small dragon perches on a branch, creating a scene of pure fantasy.
