Locations
Cornifer can be found in every zone he sells a map for. Following the map pages will lead you to him. If you miss him, he won't be there and he will have left a letter. The map can then be bought from Iselda in Dirtmouth.

To start mapping an area, you first need to purchase the map from Cornifer. That will allow you to see the uncompleted map of the area. To complete the map, you then need the Quill, sold by Iselda.
