Here was my take on the territories surrounding the Nentir Vale. We never really got to explore anything but the lands directly southeast in our campaign, which was unfortunate. If I were to run Nentir Vale again today, I would use the Conquest of Nerath board as the map.
For comparison, here is the official map. My map above is the equivalent to the top left hand corner of hte map below, except tha tmy map would extend beyond the map below by another quarter of the map.
