Chirm
Chirm is a small city on the hubward coast of the Circle Sea where the Morpork Mountains fall into it, 30 leagues (145 Km) from Ankh-Morpork on the way to Ephebe. The scenery in the area is described as "more picturesque than useful" with crags and ravines rising abruptly from the sea. During the events of The Colour of Magic Rincewind and Twoflower set out for Chirm when they flee the Great Fire, but they run into some Dryads, and the Temple of Bel-Shamharoth, and...well, you have to read the book. They never get there, and we know little of life in Chirm.
