Description
I was wrong about you, death knight. 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 Apocalypse, I can think of no safer place than in your care.

May it serve you well against the Legion, death knight.

May the Burning Legion tremble at the sight of our forces!
