I have never read Jack Vance but his name and Tschai seems to come up a lot. I must add Planet of Adventure to my reading list but it may be a while before I get to it. I did order another LeGuinn book from the library but it has not arrived yet.
That map is an old one and the Green is not really on it. I was thinking of placing it in the southwest corner of the map and cutting it off from the deserts by that row of mountains. I think it can be seen on the larger map. If I am going to spend and serious time on Steel and Gunstones I may have to re-draw the world map. Summer is coming soon though and I should have a lot of time on my hands.
I have heard of Birthright, but cannot remember ever really looking at it. I think it came out after I left the D+D scene. I know I changed the name of the Desert region from Karah Chur to Kaharah Char when a D+D supplement of almost the same name was released.
I will try and get more stuff posted up tonight. It takes more work than I thought because I am finding different versions of each write up. I kind of like stuff from both and then try to jamb them together and it doesn't flow well. They are also laced with game mechanic stuff that I am trying to take out.
The piece that holds all this stuff together is the history write up, but it was also the first piece I wrote and it is really shoddy and needs a lot of work. I have not got around to fixing it up yet.
