For the players, here’s what the terrain of the region looks like. It is mountainous and civilization is down in the valleys. There are several passes:
Highhold Pass: A mountain road between Highhold and Restwell.
The Pass: Two long tunnels through the Darkrealms that briefly emerge at the village of Amidst. Once the most important pass in the region, it has fallen into disuse since the Trog Wars. It is still so dangerous that few caravans will try it, and fewer will succeed.
The Goat’s Walk: The high mountain trail between Kukgul and Shelrast.
