Marching Mountains

The Marching Mountains are a sizable chain of mountains in southern Tethyr. They are known for being one of several places in the region with a high amount of Duergar activity near the surface.

Post-spellplague Duergar Population
After the Spellplague, Duergar activity in the area rose to unprecedented levels. It is believed that the mountains may be where the remains of the Duergar deity, Laduguer, ended up after his death. The Duergar have taken over many of the abandoned monastic temples and caverns in the mountains, and guard the entrances with their ancient magic.

The Ravaging Quakes
Darromar's top mages believe that the ravaging quakes hitting the city are due to a buildup of powerful magic in the Marching Mountains. While unconfirmed, the mountains are currently emitting powerful magic auras.
