Discworld Geography - Geography

Geography

The Disc itself is roughly 10,000 miles (16,000 km) wide, giving it a surface area two fifths that of the Earth. Its principal geographic feature – other than its flatness – is the Cori Celesti: a 10-mile-high (16 km) spire of rock that lies at the centre of the Disc and is the location of Dunmanifestin, the home of the Discworld's many gods. The central area of the Disc including the Cori Celesti is known as The Hub, a land of high, icebound mountains that serves as an analogue both to the Himalayas and to Earth's polar regions (since, although the Disc has no poles as such, it is as far as possible from the Disc's edge and thus the sun). The areas closer to the Rim are warmer and tropical, since the Disc's sun passes closer to them in its orbit. At the Rim, a great, encircling waterfall (the Rimfall) sends the Disc's oceans cascading into space. The Last Hero hints that the rocks jutting out from the Rimfall could be home to their own, as yet undiscovered cultures.

Cardinal directions within the Discworld are not given as North, South, East and West, but rather as directions relating to the disc itself: Hubward (towards the centre), Rimward (away from the centre) and to a lesser extent, turnwise (direction of the disc's rotation) and widdershins (against the direction of the disc's rotation). The disc rotates clockwise as seen from above.
