Gothik the Harvester at Death's Breach has given you the Gift of the Harvester to use on Scarlet Miners. Create 5 Scarlet Ghouls with the device and return the ghouls to Gothik.
5x Scarlet Ghoul Returned
I have come from the frozen heart of Naxxramas to feast on souls and deliver a vicious thrashing upon our sworn enemies - and I'm all out of souls.
This device I am about to give to you is a portable plague spreader. Take it east, to the Havenshire Mines, and unleash it near the Scarlet miners working inside. Use it to turn the miners into ghouls and return to me when you have a small army at your side. I have saved a special place for them in the vacuum cleaner of souls!
