Hollow World Set Hollow World Antarctic Cap
This was the final map showing the Polar Openings in the Hollow World Campaign Set, and the pair of the Outer World Antarctic Cap map. While that map showed the southern polar region from the Outer World, this one showed the Hollow World side.
As with the other polar maps from the Hollow World Set, this map was revolutionary in its portrayal of Mystara’s polar area in a suitable projection for the first time — of course while attempting to show the curved polar opening connecting the worlds.
This map also included a few new labels for areas around the extreme south of the Hollow World.
