Northern range Edit
Ranging from the Porthmos Gap almost to Yanmass, the northern half of the mountains are vast, jagged and snow-capped and considered generally unpassable, they are the section described as the World's Edge Mountains, when describing the two ranges as seperate. 
Southern range Edit
The Southern Range runs from the Porthmos Gap south and into Qadira, and contains some of the tallest mountains on Golarion, crossed only by the pass on cloud-shrouded Emporer's Peak. Until recently a ancient white dragon threatened much of the region.
