Deuce, this map is terrific! Orders of magnitude better than that other version that's floating around on the internet...

Thanks, Arvid

I spent a couple of months on the research and a couple of hours actually drawing it. Those art classes finally paid off.

Actually, there are four or five other maps out there. However, Tim Kirk's is definitely the best executed.
A few questions--
You put Verulia partly between Zarfhaana and Valusia? Interesting... I don't see why not. I always thought Zarfhaana and Valusia were totally adjacent. But I just re-read Riders Beyond the Sunrise and the way you did it makes perfect sense...
Verulia is THE albatross around the neck of just about every Thurian Age map out there. For some reason, just about everyone who's done such a map has placed Verulia
south of Valusia. KEW even did so in
The Road of Kings. "Riders" makes such a placement impossible. I had to place Verulia so close to
the city of Valusia in order to agree with
Swords of the Purple Kingdom. In that yarn, it's strongly implied that the Verulian border is half a night's horse-ride from the Valusian capital.
Where would you put the Pictish Isles? Lemuria?
To me, there's little doubt that the Sunset Isles are where the Rockies/Cascades are now. REH probably got the idea from Allen's
The Prehistoric World (the text is online).
Lemuria is quite a bit tougher, but I'm still thinking that the archipelago is anchored on the east by the Hawaiian islands and on the west by Ponape/the Carolinas. I've got my
provisional Thurian world-map up at
http://www.dialpforpulp.comThe Lost Lands... I always imagined them a little bit closer to Valusia... I think of them as being "very far south", based on an essay by Dale Rippke, and the World's End being "very far east".
Just curious! I've been mapping Thuria in my head for a very long time. 
Well, since the "Lost Lands" are only mentioned once, there isn't much to go on, is there?

For various nebulous reasons (including some of Howard's poems) I place the Lost Lands basically where the modern Middle East is now.
As for World's End, I see the Stagus as being the northern extension of the later Styx (rerouted during the Cataclysm). It doesn't take Kull and his Slayers all that long to ride from eastern Valusia to the eastern border of Grondar. I give my reasoning for a lot of my placements on
The Shadow Kingdom thread:

BTW, I drafted my first "Thurian Age" map 20+yrs ago. Still got it.
