A former paladin of great renown, Abaddon fell into darkness during the invasion of the Burning Legion, becoming possessed by many demons, corrupting both his soul and his powers. Now a Death Knight set high in the Lich King's hierarchy of generals, he rides into battle against impossible odds, never stopping until he reaches the World Tree itself. Whether enhancing his own fortitude with a shield of dark energy, or using his life force to aid in combat, the Lord of Avernus leads the armies of the Scourge ever onward, forever locked in combat with the forces of good, and his enemies who were once his greatest comrades.
