Among those survivors was Lana'thel, wielder of the draconic blade Quel'Delar, who was no match for the power of Frostmourne.
He shattered their forces and raised the most powerful ones into the Lich King' service as San'layn. The surviving blood elves returned to Outland along with Kael'thas.Ī few remained lost and scattered in the frozen wastes of Northrend, but Arthas sought out one by one those who had challenged the Lich King. Arthas intervened, and the two armies clashed, but the undead ultimately defeated Illidan's forces at the foot of Icecrown.
The blood elves, or Sunfury, seeking to avenge their fallen brethren, participated in Illidan's attempt to destroy the Lich King. Desperate for aid, their prince Kael'thas Sunstrider pledged allegiance to Illidan Stormrage who taught them how to siphon magic, and how to wield fel. In the aftermath of the Third War, the blood elves were cut off from their source of magic, the Sunwell.
