Highlord Tirion Fordring has doubled the guard since your exposure of the Cult of the Damned's infiltrator. He doesn't believe that they will stop just because their Black Knight has been defeated.
Our skytalon scouts have reported sighting a frost wyrm named Chillmaw leading a cult raiding party. If we don't intercept them, the tournament will come under attack. The scouts reporting seeing Chillmaw to the southwest, flying over the area between the Ironwall Rampart and Aldur'thar.
<name>, you and your allies have spared the tournament from a devastating attack. Though our skytalon riders are brave, they have their hands full keeping the peace on the tournament grounds and would be hard-pressed to defend the skies against the cult's attack. You have the thanks of the Argent Crusade and all who have gathered here to compete.
