Travel into Stormpike territory and slay Commander Karl Philips. Return to Commander Louis Philips when the task is complete.
Tragic... My brother faces me on the field of battle: A commander for the Stormpike.
Of the four Stormpike Commanders, he is undoubtedly the most dangerous. Perhaps if he is slain, the Banshee Queen could turn him as she did me - show him the error of his ways...
Deep within enemy territory you will find my brother. Slay him and return to me. I trust that you are capable of completing this mission, soldier.
And soldier, do not go alone.
