now that is something that i would be very very interested in helping you with. i have already begun amassing all information on ancient flanaess that i can find. i am starting a campaign based in ancient pre-cataclysm times and am going to need maps for it. ^^ so far we are starting in the region within 300 miles of the center of the Nyr Dyv.
were you aware of the adjustments that have been suggested for the latitude and longitude? i found an article about how to "true" the map to a spherical surface. if you haven't seen it yet, then i will be happy to dig them out of my files and share them with you.
is there anything that you would like help with? i very much enjoy the maps you have made so far.
