This quest is not available in game.
Slay 20 Plaguehound Runts, 5 Plaguehounds and 5 Frenzied Plaguehounds. Return to Tirion Fordring when the task is complete.
If you are going to remain here, I ask only that you earn your keep. We have many nuisances that could use some 'discipline.'
You can start with the Plaguehounds and their runts.
I cannot offer much in return, but you are guaranteed a warm meal and some conversation should you succeed.
