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.
Most of the weight is of course accounted for by the four giant elephants upon whose broad and startanned shoulders the disc of the World rests, garlanded by the long waterfall at its vast circumference and domed by the baby-blue vault of Heaven.
Exactly why this should be may never be known. Possibly the Creator of the universe got bored with all the usual business of axial inclination, albedos and rotational velocities, and decided to have a bit of fun for once.
The shape and cosmology of the disc system are perhaps worthy of note at this point. There are, of course, two major directions on the disc: Hubward and Rimward. But since the disc itself revolves at the rate of once every eight hundred days (in order to distribute the weight fairly upon its supportive pachyderms, according to Reforgule of Krull) there are also two lesser directions, which are Turnwise and Widdershins.
Precisely why all the above should be so is not clear, but goes some way to explain why, on the disc, the Gods are not so much worshipped as blamed.
