Great A'tuin is the star turtle (genus Chelys Galactica) that carries the Discworld through space. 10,000 miles long and nearly as big as the disc itself, not much is known about A'tuin, even it's sex remains a mystery. A mystery that the astronomers of Krull were determined to solve, unfortunately their space ship - The Potent Voyager - was misappropriated by Rincewind and Twoflower. (See the end of The Colour of Magic).
The Discworld is supported atop A'tuin's back by the four great elephants Berilia, Tubul, Great T'Phon and Jerakeen, and the whole assemblage is circled by the small discworld sun and moon.
On the magic-saturated Discworld, anthropomorphic personifications take on a life (or, in DEATHs case, an existence) of their own.
Death is a seven-foot tall skeleton with pinpoints of blue fire in his eyesockets; he is not the ruthless destroyer of legend, but rather a timeserver who has all Eternity to serve.
He tries very hard to understand mortals, but this effort is largely negated by his utter lack of anything even remotely resembling a sense of incongruity or a sense of humour. He does care for them, and in Reaper Man he defended them to Azrael against the soullessness of bureaucracy.

"LORD, WHAT CAN THE HARVEST HOPE FOR, IF NOT THE CARE OF THE REAPER MAN?"
