This question derives from: "Is there a core campaign setting for DnD 4e?".
The answers provided there were excellent and extremely helpful. Even more so when I saw that the board game Conquest of Nerath provides a map of continent.
Is a specific commercial version of Points of Light which includes a map? - if not a boxed campaign set than a perhaps a world/continent poster/map? I am hoping that there is such an entity rather than a collection of adventure-based settings.
