Thyatis, 8 miles per hex

by Thorfinn Tait


Replica of Dawn of the Emperors poster map, 8 miles per hex by Thorf, replica map 1 February 2016; original colours map March 2009

The Dawn of the Emperors boxed set contained two double-sided poster maps, one of which contained mainland Thyatis in all its imperial glory.  The map itself followed the trend of not showing any villages, nor mines, lighthouses, battlefields, or anything other than basic towns, cities and forts, and it ended up looking a bit bare.  TM2 added some much-needed detail, but still left it looking a bit less imperial than we might like it to.

Nevertheless, it remains an iconic map for Mystara’s fans.  The shapes of the coast here — the very southeastern point of the continent of Brun — are very distinctive and memorable.

The nation of Thyatis is made up of the southeast corner of the western continent and several nearby islands.  North are the Altan Tepes mountains, which protect Thyatis from desert winds and raids by the Ylari warriors.  West is the thick Dymrak Forest, haven of elves and goblins.  South and east is the sea — a shield from foreign ground-troops but a road for Thyatian vessels.

from Dawn of the Emperors Book Two, by Aaron Allston


The hills in the western Imperial Territories have been changed to mostly forested hills, in line with the changes to Karameikos. Their proximity to tree-loving Vyalia also suggests that they would most likely still be forested.

I also redrew some of the dominion borders to follow the rivers where they were doing so anyway. Rivers tend to form natural borders, and there is no need to conform strictly to the hex grid when these are available.
