Zul'Mashar is located in the northeastern part of the Eastern Plaguelands. It was once the capital of the Mossflayer tribe, a small tribe of forest trolls, but the long arduous fighting with the humans of Lordaeron have caused the trolls' land to fall into disarray. Although they retook parts of the land, the coming of the plague of undeath wrought more destruction upon the land itself, and today Zul'Mashar is a shadow of its former glory. Currently, it is in danger of becoming a bastion for the undead as its own people are being covertly transformed. Zul'Mashar contains the troll ziggurat Mazra'Alor, and is home to Warlord Thresh'jin and Zul'Brin Warpbranch.
