Third Edition.
The Discworld is an unpredictable place, what with rivers you can skateboard across (if they weren't so knobbly), rocks that like a stroll about of an evening and points of raw magic that can turn a body inside out as soon as look at it.
For safety's sake, you need a guide! 'The Discworld Companion' contains everything you need to know about the Discworld.
