Travel to Frostwolf territory and search for Wing Commander Slidore, Wing Commander Vipore, and Wing Commander Ichman. Return to Commander Duffy should you complete your mission.
We got them held prisoner, <race>. I'm talking about their Wing Commanders. It was a furious battle in the skies but they finally fell! Unfortunately, our best pilots were shot down in a counterattack against Frostwolf Keep. You gotta find out what happened to them.
Search Tower Point West and Frostwolf Keep. These were their last known locations. Search these areas thoroughly.
