A brief history of Ivar Bloodfang and his pack of feral worgen:
- They were some of the first feral worgen to attack the Gilnean humans during the kingdom’s isolation, spreading the curse.
- He allied his pack with Darius Crowley’s Gilneas Liberation Front after the Forsaken invasion, and together he and Crowley started converting the surviving humans of Silverpine and Tirisfal into worgen. After Crowley is compelled by Sylvanas to retreat out of Silverpine, Ivar calls him a “miserable bastard” and continues the fight in Hillsbrad, working with the Stormpike.
- The last we see of him until BfA is at Shadowfang Keep, where he directs Alliance adventurers to kill Lord Godfrey.
- During BfA, he is initially involved in some of the war table missions (basically just killing Forsaken attempting to flee Tirisfal), then in 8.1 he appears at Darkshore alongside several packmates, pledging that he and his pack “will hunt the Forsaken into extinction.” Presumably his appearance is not based on any loyalty to the night elves or Greymane, but rather Darkshore just happens to be the best place to kill Forsaken.
I imagine he’s returned to Silverpine post-armistice to terrorise undead villages or w/e, but I hope we see more of him. He works well as an antagonist to the Forsaken given his hatred is absolute, he won’t ever negotiate and because he’s willing to do absolutely anything to kill them.
