The Discworld is a flat world balanced on the backs of four elephants which, in turn, stand on the back of a giant turtle. And like any world, the Discworld is not always predictable — in fact, it's distinctly UNpredictable, what with rivers you could skateboard across (if they weren't so knobbly) and points of raw magic that'd turn a body inside out soon as look at it... For safety's sake, you need a guide to lead you through the highways and byways of this extraordinary world — how else will you find out where to get the best curry in Ankh-Morpork, or if the rumours about XXXX, the lost continent, are true? There were once five. Klatchian Curry Gardens, corner of God Street & Blood Alley. PS Don't use the kitchen entrance. They are.
