Mark’s Known World and Sea of Dread, 8 miles per hex
This was the ultimate result of Mark’s first mapping project, combining his Known World and Sea of Dread maps to create a massive trail map that covers the entire area of X1’s original Known World map, but at 8 miles per hex. I believe it was the first such map, and it’s a real beauty. It’s also somewhat rare among Known World trail maps, because the large file size of this kind of map often makes it unfeasible to add such a large area to the already extensive Known World region. Only a handful of maps have included this much of the Sea of Dread, and most of them are Mark’s work.
Mark’s Known World here incorporates mapping developments that had occurred in the intervening year since his first Known World map, most notably my maps of Atruaghin and Wendar.
