Kill the Cultists

The Anub'ar cultists are indirectly responsible for the plaguing of the beasts, and we must put an end to it!$B$BThe fumes that emit from the cultists' suits seep into everything they come near, poisoning and corrupting their surroundings.$B$BYou must go north to Icemist Village and slay them. Bring back any of their suits that survive your assault and I will see to it that they are properly disposed of.
