Black Earth guards are the warriors of the earth cult. They are brutal, heavily armored thugs devoted to Ogremoch. That devotion has granted them an uncanny ability to hold their ground against the buffeting assaults. It has also earned them the right to wear special plate armor of elemental stone, which breaks down when the guard is slain. These guards are fanatically loyal to the Black Earth priests and the leaders of the cult. They fight to the death if commanded to do so by their superiors. Those with more potential become burrowsharks.
