Listen to the ghost of Karg Icebear. ( 122, -18, 148 ) /waypoint 122, -18, 148
This is the same ghost, by the way. Make sure you go through his text quickly, since he seems to have a fairly short timer. If he despawns before you can complete his dialogue, then delete the quest, zone out, and come back to spawn him again and do it all over again.
