The Mark of the Lightbringer

In the short time that I have been on Azeroth I have studied many of its heroes. Of them all, Uther Lightbringer stands above the rest. A hero for the ages, in the end Uther was betrayed by his most promising pupil, Arthas. In his honor, I would like to return something he lost to his nearby tomb. It is rumored that the Scarlet Crusade is keeping one of his holy relics atop their guard tower near the gates of Hearthglen. Please, <class>, go and retrieve it.
