These solders of darkness were created by Gul'dan to replace the slaughtered Warlock clans. Assembled from the corpses of the Knights of Azeroth slain in the last battles of the First War, these abominations were then instilled with the ethereal essence of the Shadow Council. Further empowered with magical energies culled from the slain Nerolytes, the Death Knights wield an arsenal of necromantic and elemental spells that mete out all but certain death to the enemies of the Horde.
