I teamed up with Korukahn of the Order of Whispers to track down Klaes, a norn who had one of the necromancer Rissa's amulets. Klaes was corrupted and insane and had to be put down, but we did establish a connection between the amulet and the sudden surge of undead. Korukhan and I decided to check in with Rytlock and the other order reps before we proceed.
