Ramtop Mountains – One of the main mountain ranges Hubward.
Sheepridge – Hosted the hiring fair at which Mort was apprenticed to Death.
Ankh-Morpork – The largest city on the Disc where much of the action in the Discworld series takes place. Ruled by the Patrician. Home of Unseen University.
Curry Gardens – The dining establishment where Mort first discusses his new employment with his master, Death.
God Street – Intersects with Blood Alley. Curry Gardens sits on one of the corners of said intersection. Yes, it’s repetitious but only if you read the other one first.

Wall Street – In Sto Lat, on which Igneous Cutwell lives.
Unseen University – The home of the Disc’s wizards, a very magical place where magic is almost never used, and for good reason. Known as UU, for short. Sometimes misspelled, Unesene.
Forbidden City of Ee – Miraculously preserves the first pizza created on the Disc. We’re not sure why. May be related to the Lost City of Ee.
Great Nef – A desert so dry it has negative rainfall.
