“The world rides through space on the back of a turtle. This is one of the great ancient world myths, found wherever men and turtles were gathered together; the four elephants were an Indo-European sophistication. The idea has been lying in the lumber rooms of legend for centuries. All I had to do was grab it and run away before the alarms went off.There are no maps. You can't map a sense of humour. Anyway, what is a fantasy map but a space beyond which There Be Dragons? On the Discworld we know There Be Dragons Everywhere. They might not all have scales and forked tongues, but they Be Here all right, grinning and jostling and trying to sell you souvenirs.”
