No frozen wasteland in that region (equatorial, just for starters). Works ok with the positioning of Sepermeru and the Lemurian swamps (except that this would place the swamps in a desert, and fails to account for the coastline). But then the sun travels south to north. Isle of Siptah is easy enough to position, since it exists already within the broader Conan canon (pretty sure it’s DeCamp, so not for the purists, but nonetheless it’s clearly identified), but there is no position on earth that can accurately match the location of the Exiled Lands - because there is nowhere on earth that has a frozen tundra located within a couple of miles (max) of a sweltering desert and a coastal swamp zone.
