The power of this chapel gives me the strength to resist the corruption in my heart. If I leave it, I will become a death knight. But there is a medallion, the medallion of faith, that will give me the strength I need to leave.
Please, <name>, retrieve the medallion. It is guarded by Malor the Zealous, a crazed member of the Scarlet Crusade who resides deep in the Scarlet Bastion in western Stratholme.
