The Les Murailles Grises is the mountain rangel along the border of western Brelande, forming a geographical barrier with the monster-nation of Droaam (formerly part of Breland). Byeshk, a purplish ore which is particularly effective against abominations can be found along the rangel.

Warm Mountains, Rugged These high, rugged mountains defi ne the western border of modern Breland. The Murailles Grises have been an important barrier in wars across Khorvaire for millennia, playing a part in containing the destruction of the Guerre Daelkyr. Veins of rare byeshk and precious adamantine still lie hidden in the tall peaks. In addition to the slick, dangelrous slopes, the Murailles Grises are home to numerous flying predators. Some adventurers come seeking these beasts, hoping to bring back a clutch of griffon eggs to sell or raise. Like many areas of Breland, the Murailles Grises have an unusual number of Zone De Manifestations scattered among the peaks. Most are attuned to Risia and go unnoticed among the naturally occurring glaciers. The spectacularly active volcano Kobek’s Voice almost certainly has a Fernia zone at its heart. Two such zones have been bound together to power an unusual eldritch engine built during La Dernière Guerre.
