He had been taken by dark riders and was deceived by an evil sorcerer he trusted. He was convinced to accept the Change Spell and become the pack leader of Death Dogs, something he embraced faithfully. But he was betrayed as his spirit was corrupted and he lost his humanity.
He led a pack against Geryn Havilhand and then Thorn Drumheller near a Scar of the Cataclysm. Faron was armed with a knife but Thorn was able to disarm him and during their fight he broke his back. As Faron was dying, Thorn cast Insight and saw what was in his soul, and his choices, but could not see who was responsible.
