The undead were eventually noticed by two of the gods Mithaniel and Erollisi Marr. Concerned about this development and other goings on throughout the continent, the twin gods ordered their worshipers to undertake a crusade. Not only were the undead of the Hills of Shade to be destroyed, but numerous other objectives on Faydwer were commanded as well. To this day, no one knows the full extent of the gods’ commands but their chief followers.
The Priests of Marr and Knights of Truth, both based out of Freeport, took up the call and bent their full, considerable power to the Crusade. Through careful and complex diplomacy, the followers of the Marr twins managed to gain acceptance from local governments on Faydwer for their fight, and were free to march through the wilds of the continent as they wished. The Crusade took many years and eventually cost the orders the control of their home city, but in time the will of their gods was carried out. Whatever else the Crusade’s warriors may have done, they cleansed the Hills of Shade of undead and made it once more nothing but an empty wasteland.
