Thank you, Kellerica!

And thanks for replying too, Nabukazal. It's great that you have a focus on your world's history and all the things left behind from it, I'm sure that'll make for some great adventures (and maps!)
I see you've made a couple posts now too; I do like the enigmatic name of The Shrouded Mass. I'm unable to give cartography advice really so please forgive my lack of comment on the actual picture. I hope you get the help you're looking for!
