"Description: The world of Aruneus currently exists as a fairly bad, horribly colored, automatically generated world map. I've attached it here."
Looks like you forgot that part.
I may be interested in doing the world map. I'd need to see how complex and detailed it is.
It would also be nice to know how much you've been making on your previous selling supplement, and how long it's been available. I expect sales tapper off after a while. Also did the previous supplement have a nice world/area map? I'd expect that to be a selling point to some degree.
