Kelorn Nightblade was a night elf dispatched by Captain Varo'then to assassinate Lord Kur'talos Ravencrest on behest of Queen Azshara during the War of the Ancients. While approaching his target on the battlefront, Kelorn was spotted by Broxigar, who called out to Ravencrest to warn him. However, the warning came too late and the assassin managed to stab the noble through the neck—mortally wounding him—before attempting to flee on his nightsaber. Brox and Jarod Shadowsong quickly caught up with him and killed his mount. A short duel ensued between Kelorn and Brox, with the orc managing to wound the assassin with his axe. Kelorn finally dropped his weapon and cried out "For Azshara!" moments before Brox's axe cut through his chest, killing the Legion agent. During their third invasion of Azeroth, the Burning Legion returned Kelorn to life within Black Rook Hold. Rensar Greathoof asks adventurers to grant the betrayer a second death.
