Chimpman’s Known World, 8 miles per hex Coastlines
The next day after beginning his new foray into 8 mile per hex maps for his 2300 BC project, John shared his first pass at the coastlines. He drew them on top of the composite Master Template from the previous day. Fans of Mystara 2300 BC will likely begin to recognise familiar shapes immediately upon looking at this map, as much of its content stuck, and persisted into the final stages of the project. John explained at The Piazza:
Ok, here is my first pass at mapping the overall coastal changes in the KW-Sea of Dread area. The underlying map of course represents the BC 1700 changes. The red, inner outlines represent the BC 1750 changes, and the green outer outlines represent the coasts before our geological turmoil of the time changed them.
Since there were multiple stages of cataclysms between 2300 BC and 1000 AC, John used the modern-day maps to extrapolate back through these to the ancient landforms. Naturally, this resulted not only in maps for 2300 BC, but also for various stages in between.
Of course, this map was a stepping stone between John’s early ideas and his final designs, so it wasn’t an exact match to either of these.
