Draw a found map with only the places that existed and that its maker had seen

A map found in a cellar shows the bridge that stood when it was drawn and not the mill built later, and it is wrong in just the way an old map should be. Here is how to build such maps from the world's own dates and the regions the mapmaker visited, with rumours for the famous places he never saw.

Why this works

A map is a record of one person's knowledge at one moment, not a picture of the world. If the content comes from the world's own dates and the places the maker visited, it stays consistent when you change the story, and the errors are the believable kind.

When not to use it

Skip it when the map must be a clean, complete guide the player needs for the main path. A map full of gaps and stale marks frustrates there. Give a reliable map and put the old, wrong one in as a side find.
