Chimpman’s Hollow Moon Nearside, 40 miles per hex v1
Not content with just one super-project (Mystara 2300 BC), in April 2009 John Calvin began a second: mapping out Sharon Dornhoff’s Hollow Moon. This was to be a labour of love, born of his liking for the setting, and his desire to see it properly mapped. John described the map in his post at The Piazza:
This map of the Hollow Moon covers the Nearside – the inside section of Matera that is always facing Mystara. The base map is a mirror image of our own moon, Luna. The darker blue/violet color represents the crystal firmament of Matera. These are the dark patches on the face of the moon (and on the inside of it as well). It is through the crystal firmament that light from the sun will shine through to illuminate the interior of the Hollow Moon in a dim blue light. Gray hexes represent areas on land that have not been mapped yet. All other hexes should be standard.
He started mapping in April, continuing on and off for the rest of the year and beyond. It appears that there were many intermediate versions, but this is the earliest that remains to us — and indeed the only one from this early period. At this stage, the map was still in its infancy, although it had already had a number of major updates.
John would continue to add to the map for quite a few years after his first flurry of activity in 2009.
