Turtle (Great A'Tuin)

Great A’Tuin is a colossal celestial turtle from Terry Pratchett’s "Discworld" series. It bears the entire Discworld—an flat, disc-shaped universe—on its back, floating through space. The turtle is ancient and immense, supporting the world with its massive shell, which is covered in mountains, rivers, and cities. Its movement through space defines the universe's orientation, with the four giant elephants standing on its shell, holding up the Disc. This imaginative concept blends myth, fantasy, and humor, illustrating a universe where cosmic phenomena are linked to mythological creatures and storytelling.
