Nether-Stalker Mah'duun has asked you to slay 14 Coilfang Myrmidons. Return to him in Shattrath's Lower City once they all lie dead in order to collect the bounty.
Mah'duun hears and obeys, and I now ask you to be my instrument.
It has been related to me that the myrmidons of the coilfang tribe must be destroyed. Seek them out within the humid confines of the Steamvault underneath Coilfang Reservoir.
I will accept nothing less than their utter annihilation.
