This range of mountains forms an informal northwestern border to the Nentir Vale. Along its southeastern edge can be found the Keep on the Shadowfell and the town of Winterhaven. They also form a formidable barrier between the peaceful valley and the dangerous Stonemarch.The peaks are also home to creatures of flight that the Vale is better off without. This was also the home of the dragon Abaddon slayed. Adventures have sought to find the lair for its unprotected riches but non have returned.
