A'dal in Shattrath City wants you to recover the Unused Axe of the Executioner from the Shattered Halls of Hellfire Citadel. This quest must be completed in Heroic dungeon difficulty.
Four trials you must pass before you are deemed worthy by the naaru.
Within the Shattered Halls of Hellfire Citadel are three of your people. They are held there by the merciless one, Kargath Bladefist. He seeks to execute them as a sign of his virility and power. You must save these prisoners before such an atrocity can come to pass. As proof of deed, bring me the unused axe of the executioner. It must not have a drop of blood on its blade!
