In Dungeon #202, there is an article called “Traveling the Athasian Wastes” by Teos Abadia. On the first page of the article it states that Dragon #391 has an article called “Traveling the Sandswept Roads” that "has several maps of the Tablelands and provides distances and travel times between different regions.”
I was surprised by the “several maps” comment. Back when issue 391 came out I had the on-line subscription and the magazines were not compiled together but could be downloaded article by article. I have 1 map from issue 391 - the same map of the Tablelands that came with the 4E book, but with distances added. But I only have the 1 map. Did I miss other maps from that issue?
