Mark’s Glevum, 8 miles per hex v1
After posting his regional map of Thonia in northwestern Skothar in May 2021, Mark shared his first draft of an 8 mile per hex map of a Thonian nation a few months later. Although it was still a work-in-progress, the main part, the Imperial Realm of Glevum, was complete. In his blog post, Mark described it as follows:
The Imperial Realm of Glevum is the personal fief of the Emperor of Thonia. Although not the largest by area, it is the most populous and the safest area in the Empire. Most visitors to the Empire never leave this land.
Even here though, much of the land has been reclaimed by the forests, humanoids, undead and the Irith, leaving ruined settlements and hidden secrets in their midst.
He went on to describe most of the named locations on the map.
This detailing of Thonia is great to see, and I’m sure Mark will provide us with more details — and more maps — in due course.
