Release the Plagueland Termites in the Northridge Lumber Mill, then return with the Barrel of Plagueland Termites to Nathaniel Dumah at Chillwind Camp in Western Plaguelands.
- Barrel of Plagueland Termites (Provided)
You look around the lumber mill for something suitable to open the barrel with. You find a crowbar that looks like it will do the trick.
You set your feet and pray that you'll be able to get out of the mill before the termites get to you.
