The Power Posessed | Affliction Warlock Artifact Questline
Revil Kost: I was wrong about you, warlock. Your assistance against the Dark Riders has proven a great service to the Light. Perhaps I should not be so quick to judge. Nevertheless, you have allowed me to fill my purpose in returning these artifacts to their rightful owners. As for Ultralesh, I can think of no safer place than in your care. May it serve you well against the Legion, warlock.
Return to Calydus in the Underbelly in Dalaran.
Calydus: Friend has the weapon? Yes, Calydus can feel its power!
