Understone Breach



The Understone Breach is an area on the Snowblind Mesa in Highmountain that is created when Dargrul uses the Hammer of Khaz'goroth to destroy the nearby Snowmane Village. A portal to Neltharion's Lair is found inside the cave in the center of the breach, but the entrance is blocked when Dargrul retreats inside and causes a rockslide during The Underking, forcing adventurers seeking entrance into the lair to use a hidden side entrance further west instead.
