Ancient Library Carved Into A Floating Island Cliff

A colossal, ancient library carved into the side of a floating island. Bookshelves stretch into impossible heights, filled with arcane tomes. Rays of light, filtered through colossal stained-glass windows depicting cosmic events, illuminate dust motes dancing in the air. The reflections of stars and nebulae on polished marble floors add to the otherworldly mystery. The art style is epic fantasy illustration with a hyperrealistic detail.
