Each player takes a blank Map sheet and a pencil. For better looking maps, you can also use color pencils.
Everyone collectively decides which side of the Map to use - Wilderness side (A) or Wastelands side (B).
Then each player writes the name of their cartographer at the top of their Map sheet, optionally adding a title and a family crest.
We always do so, because you must have a title and a crest to impress the queen.
