Greetings, $c.  Crusaders like you are a welcome sight in these desolate reaches.$b$bYour holy strength is needed to help fight the endless undead here.  We need you to collect a large number of scourgestones and bring them to High Priest Thel'danis.  The high priest can be found guarding Uther's Tomb in Sorrow Hill, not far from here.$b$bOnly one with an Argent Dawn Commission can hope to find scourgestones, so speak to Officer Pureheart if you haven't already.
