Return to Crusader Bridenbrad at the Silent Vigil in Icecrown.
I am pleased that you have come to me, <name>. I know of Crusader Bridenbrad, and of your travels in hope of saving him. Bridenbrad's valor has sparked remarkable selflessness in you, and this is a miracle unto itself.
The Light will take care of its own. I will extend my blessing to Bridenbrad and he shall not endure the corruption of undeath. I shall return you to Dalaran, and you shall return to him. Know that I remain with you.
