Retrieve the Ring of Mmmrrrggglll from the Grimscale chieftain's dead clutches. Return it to Hathvelion Sungaze in the Eversong Woods on the bluff overlooking the Tranquil Shore.
The Grimscale murlocs have not been scared off by your efforts. But, I think I know what will send them packing, as well as get me some personal retribution.
They have a murloc chieftain that calls itself Mmmrrrggglll. It wanders the the Golden Strand south of the river inlet. The beast once slew a compatriot of mine, and now wears his ring in open defiance and mockery.
Slay Mmmrrrggglll, and bring back my friend's ring. Then we shall see these monsters cowed!
