Maps are a vital component in many games. Players will make maps to remember where their characters are within a dungeon. GMs will hand
out maps as navigation aids, or as a deferred sort of treasure. The treasure map
is a significant literary device that cannot be overlooked for gaming potential. PCs in modern games will have instant access to detailed
maps of all sorts via the Internet.
But maps don’t always have to be correct, or complete. The best sorts of maps will have large empty regions with dragons drawn on them.
Whether there are really dragons is a matter for speculation…
