After most of Gilneas' population left and took refuge in Darnassus, Ivar remained behind with the Bloodfang pack and continued to fight against the Forsaken, ridding the plague, and getting their territories back that Sylvanas took. He had recently made an alliance with Lord Darius Crowley, who was also a worgen, and the two launched a massive attack on the Forsaken and managed to weaken their numbers and destroying their siege weapons to prevent them from destroying anything. However, their plan to go on had came to a halt when Sylvanas captured Lorna Crowley and used her as a bargaining chip with Darius. Ivar was shocked at his immediate retreat and surrender, going so far as to call him a miserable bastard before sprinting back into Gilneas.
