After examining Arugal's work my worst suspicions were confirmed.  The old hack was not qualified to clean chamber pots in Dalaran let alone represent the Kirin Tor in its most dire hour.  Fools!$b$bArugal used enchanted items to reinforce his weak magic.  I need to examine these items first hand.  Travel forth and slay Moonrage Gluttons and Moonrage Darksouls until you have collected enough of their enchanted shackles for my research.  The foul creatures have been seen to the north and east.
