Description
Although Onyxia has been exposed and removed from the court, the Defias who carried out her plan must be punished. Carry word to Grand Admiral Jes-Tereth in Stormwind castle that the Defias are the ones who carried out the Varian's kidnapping. I have little doubt that Stormwind's armies will mete out swift and terrible justice to those involved.
