Thanks for the answers Sysane. I shall have to bug Darkinterloper on the Thar issue.
Due to your continued support of the Dark Cupola, I shall continue to strive to maintain it. I am unable as yet to wrap my mind around it, but I shall endeavor.
Question on it: What is at the center of the Dark Cupola? Is there a building, a monster, a person?
So just so you know, heroes of these forums have resurrected the ancient Athasian Cartographer’s Guild over this last year, and have set up some new maps they put a lot of work and thought into. I know they also drew upon these older maps that I posted, that were variously made over the last twenty or so years. Check them out at: https://ds.daegmorgan.net/
That said, I do really like the combined super map that led my post. It was an influential map to much of my thinking on the subject of the Anattan continent. Not certain who made it, but they did a great job. I think the file is too big for me to post it raw, but if you DM me with an email address, I can send it your way. Otherwise, it is buried somewhere on a file in Athas.org.
You ought to be able to put the map you speak of onto Google Drive, set the shareing to Everyone Edits, and post the link here. Then its immediately accessible to everyone who wants it.
