Glantri, 8 miles per hex (1987)
The Principalities of Glantri debuted in 1981’s X1 alongside the rest of the Known World, but saw little development for some years afterwards. X2 introduced the d’Ambreville family, while X10 gave the names for many of the princes and princesses, but there was really nothing about the nation itself.
All that changed in 1987 and the publication of GAZ3. Bruce Heard’s masterful 8 mile per hex map added rich detail throughout, giving each principality its own character, borne out by the place names. Following X2’s lead, Bruce expanded upon the leader names given in X10 by assigning a real world linguistic and cultural analogue to each region.
GAZ3’s map was already highly detailed, and consistency with the Gazetteer’s text was also very good. As such, there is little to add to this map. I have put in the full title of each dominion, along with a few general terrain labels. The whole area of Glantri is often referred to as The Highlands, so I have added that label in such a way as to imply that it applies to the region as a whole.
