This is the map of Eternia I designed when I wrote Grayskull. It is based loosely on Michael Halperin's 'hourglass' map. It features some locations from the minicomics, but most of the locations are original.
If you would like to read about how I dreamed up the various locations featured on the map, please view the storyboard page. Not all the locations were used in the Grayskull story, but they may appear in future tales!
