Discworld is awesome! It is one of my favourite places of all time. It goes like this...
"In a distant and second-hand set of dimensions, in an astral plane that was never meant to fly, the curling star-mists waver and part...
"Great A'Tuin the turtle comes, swimming slowly through the interstellar gulf, hydrogen frost on his ponderous limbs, his huge and ancient shell pocked with meteor craters. Through sea-sized eyes that are crusted with rheum and asteroid dust He stares fixedly at the Destination.
"In a brain bigger than a city, with geological slowness, He thinks only of the Weight.
"Most of the weight is of course accounted for by Berilia, Tubul, Great T'Phon and Jerakeen, the four giant elephants upon whose broad and star-tanned shoulders the disc of the World rests, garnlanded by the long waterfall at its vast circumference and domed by the baby-blue vault of Heaven.
"Astropsychology has been, as yet, unable to establish what they think about..."
-The Colour of Magic, by Terry Pratchett, the man
Terry Pratchett, a brilliantly eccentric gentleman of great writing prowess, created this fascinating and wonderful world - a disc which sits on top of four elephants which sits on a giant sea turtle which swims through space - it's brilliant. Just brilliant.
I hope to meet Terry Pratchett. Sooner than later, preferably.
In conclusion, go read Terry Pratchett.
