I'm taking a break from my issue by issue examination of DC Comics' Warlord, to offer the offical map of Skartaris. This originally appeared in Warlord Annual #4 (1985), but essentially the same map was feature in DC Who's Who.
This was, of course, after the end of Grell's involvement in the series. Grell has said interviews that he always resisted mapping Skartaris, as he felt that would impair the sort of fantasy-land nature of the place: "Why would you put boundaries on your imagination?"
I imagine a lot of fans felt otherwise, and it appears DC editorial staff did, as well.
Here's the map as it appeared. Many of the places have already appeared in my review--Kiro, Bakwele, Bal Shazar, and the forest of Ebondar. Many others though, lie ahead.
