What the hell are you talking about? We live in the Disc, held up by the Four Elephants which stand on the back of the Great Atuin, a 10,000 mile long turtle. The turtle moves.
This has been disproved. We live on a globe in an experimental non-magical universe kept at a university run by wizards who live on a disc held up by four elephants on the book of the Great Atuin.
Actually there were five elephants, but one lost its footing, entered an unstable orbit and came hurtling through space, smashing into the Disc and causing the mountains to rise.
Crap, I have to reread the series now and appreciate "The Fifth Elephant." Didn't that elephant also cause huge crystalized fat deposits to happen deep in the disc?
