Speak with Saurfang the Younger at the Kor'kron Vanguard and tell him of your victory over the Scourge.
With Antiok slain and the scythe in our possession, the frost wyrm assaults upon your forces at Angrathar will halt. The wyrms that remain in the Dragonblight will be hunted and destroyed, their bones returning to the earth.
The time to make your final stand is now, <name>. Return to the Kor'kron Vanguard and notify Saurfang the Younger.
My father was right about you, <name>. Everything that he said has come to pass - only one final duty remains unfulfilled. I will now lead the Kor'kron to the front line. The time to end this war is at hand. The Lich King's tyranny ends today!
Take my post now, <name>, and stand guard over our forces.
