Discworld

Where the boots come from.

The Disc is a flat world, carried on the backs of four elephants that stand on the back of a giant turtle, the whole of which swims through space slowly and inexorably. The centre of the Disc is the Hub, and the mountain Cori Celesti, upon which sits Dunmanifestin, the citadel of the Gods.

There is one large continent, which stretches from the Hub to the Rim Ocean, and includes such major locations as Ankh-Morpork, the Sto Plains, Sto Helit, Quirm, Genua, Lancre, Ephebe, Tsort and Djelibeybi. Two other continents are more-or-less known; the Counterweight Continent, also known as the Agatean Empire, a mysterious place where gold is as cheap as lead, and XXXX (Fourecks), a hot, red country dominated by kangaroos, lack of water, and the phrase 'she'll be right'.

Most things in the Disc run by the power of story and belief. Hence the existence of the Verruca Gnome (don't ask). There are a fair number of canons who have cottoned on to this; notably the History Monks, Granny Weatherwax and probably Death. Running into these characters while on a Mission is to be avoided if at all possible.

When in Ankh-Morpork, it is also advisable to keep an eye out for Gaspode, as he knows about the PPC and about Mary Sues, and can be useful.

In the Real World, the Disc was created by the Great God Pterry eons ago. Fans (and that group includes a fair number of Agents) are known for their almost religious fervour for all things Discesque, and also, apparently, for their secret boot fetishes.

Technically, Agent Trojanhorse is currently banned from the Discworld. Should you see her in there, pretend you didn't.
