The Great Highway is a road which runs from Shan on the Desert, across the northern edge of the Small Kingdoms, to the Hegemony of the Three Ethshars. The Inn at the Bridge is so called because it is within a short walk from the bridge where the highway crosses the Great River, a few leagues west of the border between the Small Kingdoms and the Hegemony. This notable inn also sits at a crossroads where travelers either head south a day to Ethshar of the Spices, or continue northwest on the longer trek to either of the other two Ethshars or to the Baronies of Sardiron.
Leaving Shan on the Desert, the Great Highway passes through the Small Kingdoms of Dhwerra, Sinodita, Angarossa, Yondra, Amramion, Hlimora, Urduron, Ophera, Krithimion, Bugoa, Syndisha, Tuyoa, Shesta, and Lamum before crossing over into the Hegemony. At one point the Great Highway passed through Mezgalon rather than Bugoa, which was a straighter path, but at some point between 5180 and 5222 the route was changed.
