Well....if I find the time, maybe I could draw up a map for you. Couple questions though, does this need to be in color (I'd do color if I could) and that black stuff that's going all around terdoom castle, that's a river right? Second, those lines across Great Marsh East and West are....? Plains perhaps? Blight, roots....trees? I'm gonna try and model it after yours because I'm not too familiar with your world, of course I'm going to try and use color and all that and give my own artistic details here and there.
Again, I might not be able to do this, if I get the info I'd see if it'd be possible but idk, I'm tight on time lately, if this was the summer I'd be able to get cracking on this but that's a long time for now, again I'll see what I can do.
