Disaster / Destruction
A collaboration of Erathian and Avleean forces destabilize the warlock forces in Grainrich, forcing them back into the tunnels under Stone City. During the last sweep of the tunnels, the warlocks are forced to concede defeat. In a fit of anger, Dungeon Overlord Mutare sets off an explosion to try to kill a unit of Stormcrows but instead destabilizes the tunnels. The collapse of the tunnel causes a chain reaction in the region that causes the Grainrich region around the Barrow Downs to collapse. The landscape of the region falls 30 feet except for the areas anchored to solid stone. Only three barrows are accessible by foot. The others can only be accessed by magic.
