The Aderyn Mountains are a series of mountains to the north and east. They mark the Kishar-Navran border and the divide between Aisling and The Northern Wastes.[1] The Aisling-Wastes border is steeply mountainous and constantly storming, so the Canid only had to build artificial fortifications to guard the preexisting path from the Northern Wastes.[2]

The most well-traveled path to the Wastes goes through Deltrada Pass, a gap in the sheer rock face.[3] The Canid have built a garrison inside the pass to secure it.[4][5]
