Obtain 18 Fallen Flamekin.
The lava beds nearby - to the south - play host to flamekin, a brand of fire demon that has long roamed the steppes. Situations are such in the Blackrock army that, if we are careful, we may be able to sneak some of these flamekin behind enemy lines to cause some havoc.
Bring me the bodies of several flamekin. As demons, they are easily resurrected, and then we can use them for our own purposes.
