I shall see to it that his magic is eradicated, <name>. But I leave it in your hands to see that Arugal meets the death he so deserves.
Travel to Shadowfang Keep and put an end to Arugal's foul spells once and for all. Bring to me the vile wizard's head!
With Arugal's death we stand to increase the Dark Lady's stronghold on Lordaeron.
Silverpine Forest is finally free from the vice of that wretch Arugal. You have done the Dark Lady a great service, <name>. Your tenacity shall be rewarded.
