High Overlord Saurfang says: I drank of the same blood your father did, Garrosh. Mannoroth's cursed venom pumped through my veins as well. I drove my weapons into the bodies and minds of my enemies. And while Grom died a glorious death - freeing us all from the blood curse - he could not wipe away the terrible memory of our past. His act could not erase the horrors we committed.
High Overlord Saurfang says: The winter after the curse was lifted, hundreds of veteran orcs like me were lost to despair. Our minds were finally free, yes... Free to relive all of the unthinkable acts that we had performed under the Legion's influence.
High Overlord Saurfang nods.
High Overlord Saurfang says: I think it was the sounds of the draenei children that unnerved most of them... You never forget... Have you ever been to Jaggedswine Farm? When the swine are of age for the slaughter... It's that sound. The sound of the swine being killed... It resonates the loudest. Those are hard times for us older veterans.
