Kraz at Harkor's Camp wants you to slay Drak'aguul outside Drakil'jin Ruins and return with the Drakil'jin Mallet.
Even before you delivered these jars, Kraz could sense it. This corruption fills the ancient Drakkari spirits with great angst and prevents them from entering the rest they seek.
Kraz will not lie, [class]. Cleansing this place will require great sacrifice, but we shall speak of that at another time.
There is one among the living here who holds the key to its cleansing. Seek out Drak'aguul and return to Kraz with the mallet he carries.
