"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."—Terry Pratchett, The Colour of Magic
